GENERAL TAP INSTRUCTIONS

Be sure to look in the "Specific Scanner Info" directory to see if your scanner is listed.

Finding the Right Pin

---

Look on the charts provided in this directory for your scanner. If your scanner is not listed, find a model that is similar to yours and look at the chip number listed. Try to find that same chip in your scanner. If multiple pins are available (for AM, FM, NFM, or WFM), you will want the NFM (or FM) pin for most decoding applications.

To find pin 8 or 9 (or whatever pin you need) on the discriminator chip, you have to know which pin is pin 1. Most chips will have a small circle by pin 1 or an 'indent' in the chip between pin 1 and the last pin. The pin numbers increase as you go around the chip in a counter-clockwise direction.

Examples:

   ______

1 |o | 16 2 | | 15 3 | | 14 4 | | 13 5 | | 12 6 | | 11 7 | | 10 8 |_____ | 9

  ___ ___

1 | U | 16 2 | | 15 3 | | 14 4 | | 13 5 | | 12 6 | | 11 7 | | 10 8 |_______| 9

One Wire or Two?

---

The information in these files give the location where you need to solder the discriminator tap signal wire. To find a ground point on your radio, the best method is to use a continuity tester (Ohm meter) and find a location that has a zero ohm difference from the outside of the antenna connector or other known ground point. Many scanners with metal cases do not need a ground wire soldered, becuase the jack you install will automatically be grounded by the case.

• You should have some soldering skills before attempting this modification.

Tools you will probably need

---

1. Fine point soldering iron (around 60 watts) 2. Rosin core Solder (60/40 .032 light duty works fine) 3. Wire cutters/strippers 4. Philips Screwdriver or other tools to open radio 5. Drill and bit for jack mounting hole 6. Pliers to tighten jack nut 7. Ohm meter (continuity tester)

General steps to discriminator tap mod

---

Mod overview: Determine Jack location->Solder tap wire ->Install jack->solder to jack

Details: 1. Open the radio on a soft surface to avoid scratching the case 2. Before you do anything else, determine IF and WHERE you can install the jack - some handheld radios are so tight, there is almost no way to install a standard jack inside the radio. 3. Locate the discriminator tap point that you will solder to. Soldering directly to the discriminator chip pin is not always the best place to solder to. Many scanners have a test point that is easier to solder to. Use an Ohm meter to see if there is an easier place to solder to. 4. Strip some insulation off the tap wire. If you are going to wrap the wire around something, strip about 1/4 inch off the insulation. If you are soldering to a solder pad, strip about the width of the solder pad. The more exposed wire you leave, the greater chance there will be for a short circuit. 5. Leave the tap wire as long as possible until you know the exact lenght you will need. It does not hurt to leave the wire a little longer than necessary. 6. "Tin" the tap wire by melting a little solder to the exposed end - this will make it easier to solder in place. 7. Solder the tap wire to the tap point on your radio - do it as quickly as possible to avoid excessive heat to the chip, or dislodging the post you are soldering to. 8. If necessary, solder a ground wire in a similar manner. 9. Route the wire to the location you have chosen to install the jack. 10. Strip some insulation off the other end of the tap wire and tin the end with some solder. 11. Figure out if it would be easier to mount the jack before soldering to it or afterward. 12. Drill a hole to mount the jack, slow rotation of the drill bit works best. Keep metal shavings from falling into the scanner. An 11/64" drill bit is about the right size for a 3/32" jack. If you want a tighter fit start with a 5/32" bit. A counter-sink or much larger drill bit works well to remove the rough edges of the hole you drilled. Turn the radio upside down and blow out any shavings that may have fallen into the radio. 13. Thread the tinned tap wire through the hole on the jack that goes to the TIP of the jack. 14. Solder the wire in place. 15. Solder a ground wire if necessary (if you are mounting the jack to a plastic case, you will need a ground wire). 16. Mount the jack. 17. Close the radio.

Warnings: - Be careful not to melt the plastic case with the soldering iron! - Adding solder in the wrong place may ruin your scanner - Watch out for short circuits when choosing where to place the jack - Doing this mod will void your warranty - Perform this mod at your own risk! The mod is simple, but if you don't know what you are doing, you can ruin your scanner.

       Setting up trunker for the first time					Brett Miller 2002

First, you are encouraged to read all the documentation that comes with Trunker. A lot of time went into the documentation. It might not always be easy to find the information you are looking for, but most of the info is in there.

There are two things you need to do to your computer before Trunker will run: Edit your AUTOEXEC.BAT so that it points to the TRACKENV.TXT file you created. Create a file called TRACKENV.TXT which contains information trunker needs to run properly.

1. Editing your autoexec.bat In Windows, Click the ‘My Computer’ icon of the desktop. Then click on drive ‘C:’ In the root directory of drive C: you should see a file called autoexec.bat Right click on the autoexec.bat and select Edit from the popup menu. Your autoexec.bat file should open in Notepad. Add the following line after the last line in your autoexec.bat: SET TRACKENV=C:\TRACKENV.TXT

This tells you computer that the information needed when Trunker is launched is in a file called TRACKENV.TXT which is located in the root C: directory. If you want to put your TRACKENV.TXT file in another location, change this line accordingly. Example:

SET TRACKENV=C:\DIRECTORY\TRACKENV.TXT

2. Creating a TRACKENV.TXT Launch the Notepad application and create a file called TRACKENV.TXT Here is a sample file you can start with:

TRACKSLICERPORT=COM1 TRACKSLICERPIN=DSR TRACKSLICERMODE=INVERT TRACKSCANPORT= TRACKSCAN=PCR1000 TRACKSCANPARK=851.0000 NEWRADIO=10 NEWGROUP=8 FILTERLOG=1

Save this file to the root C: directory (the same directory where your autoexec.bat is located).

Here is what each line means: TRACKSLICERPORT=COM1 ßThis tells Trunker on which serial port to look for your data slicer. TRACKSLICERPIN=DSR ß This tells Trunker what pin on the Com port the signal is on. This Data Slicer puts the signal on DSR. In general, if you don’t know what the setting is, leave it as CTS and try all the different settings within the Trunker program. When you figure out the right one, come back and edit this file with the correct entry. TRACKSLICERMODE=INVERT ßSome scanners output an inverted signal and some don’t. This will either be NORMAL or INVERT. You can toggle between NORMAL and INVERT within Trunker to find the right setting, then come back and edit this file (since Trunker will not keep the setting after you exit the program). TRACKSCANPORT=COM1 ß This is the Com port that Trunker will use to control your second scanner (must be on the list of controlled scanners). You if have a Super Data Slicer with serial pass-through, this will be the same Com port as your data slicer. TRACKSCAN=PCR1000 ß This tells Trunker which protocol to use to talk to your scanner so you can follow conversations and hear the audio. See the Trunker Docs for a list of supported scanners. The Pro-92, 93, 95, 2067, and 2053 cannot be controlled by Trunker. A BC245XLT or 895XLT are good inexpensive scanners if you need to purchase a second scanner for the audio tracking. TRACKSCANPARK=851.0000 ß This is the frequency Trunker will ‘park’ the audio scanner on if there is no activity to follow. Some people choose a quiet frequency, while others choose an active frequency so they can hear activity while Trunker has nothing to follow. NEWRADIO=10 NEWGROUP=8 FILTERLOG=1

MODE and PIN settings The TRACKSLICERMODE and TRACKSLICERPIN settings are the ones that cause the most problems for people because most of the time you don’t know what to set these at. If you don’t know what the settings should be, do the following:

Make sure your tapped scanner has a good control channel signal and is in MANUAL mode (the volume setting does not matter). Make sure your data slicer is plugged in to the tapped scanner Make sure your data slicer is plugged into the serial port on your PC Make sure you have edited the AUTOEXEC.BAT file and created the TRACKENV.TXT file. Start Trunker and wait to see if you get a signal % in the top right corner of the screen. If it says “wantCTS” or “sig?inv” you need to change one or more settings. Look at the Command / Response Area at the bottom of the screen. Hit the Space bar to view the second screen of menu options. Hit ‘C’ for Configure (Cfg) a. If it says “sig?inv” in the top right of your screen press ‘m’ to toggle the mode setting and wait to see if that gets it working. b. If it says “wantCTS” press the ‘p’ key to make Trunker look at another pin. You may have to press this twice to toggle between the 3 different pin options (CTS, DSR, DCD). You may have to wait about a minute before the signal % updates itself. c. You may need to try all six combinations to find the right one. i. INVERT – CTS ii. INVERT – DSR iii. INVERT – DCD iv. NORMAL – CTS v. NORMAL – DSR vi. NORMAL - DCD If this doesn’t solve the problem, you may have the wrong Com port specified. Go back the the TRACKENV.TXT file and change the TRACKSLICERPORT setting to a different serial port and do the above steps again. If it is still not working, it is very likey that Trunker is not seeing the Com port. Running Slicer.exe is a good test for this.

Checking the Hardware

The data slicer should be putting out about 2 volts AC between pin 5 (Ground) and 8 (CTS) on a 9-pin connector (DB-9)

If you are not seeing the right voltage on the data slicer port (the 9-pin connector that attaches to the computer). Check the scanner to see if the discriminator tap is working. You should see around 0.2v AC or more at the discriminator tap output. Different scanners put out different voltage levels.

Win2k_XP_ConfigHelp

Note: The following text has been copied from various Internet postings (mostly from the Trunker yahoo group) that deal with getting Trunker working under Windows 2000 and Windows XP (there is also a Microsoft Bulletin relating to Windows 98 & ME at the bottom). I am not the author of these postings and cannot comment on their accuracy. You can search the Trunker Yahoo group to get the full context of the discussion. This is intended to provide general guidance. Do so at your own risk. www.dataslicers.com

Go to Lindsay Blanton's fine site www.trunkedradio.net and download slicer.exe. Open a command prompt (or run straight from DOS) and connect your dataslicer to the com port and discriminator tap. Type in "slicer 1" (or 2 if your slicer is on com 2) and watch the screen. When tuned to a Motorola or EDACS control channel you should see defined spikes. Read the slicer.exe docs to decipher the screen display.

Slicer will tell you what pin on your serial port the data appears on. Trunker works on the CTS, DSR and DCD pins. While these are usually chosen in the track environment settings they can be toggled within Trunker. Press the "C" key to get to the Config menu and then use the "p" key to toggle between the 3 pins available. Also try toggling the Invert/Normal polarity by using the "m" key on the Config menu.

I think you will have much better results using the MMX200 machine with the version of DOS that comes in Windows 98. While I often run Trunker within Windows on my own 200 MHz Pentium with Windows 98 I find I have somewhat better results running from DOS, not in a DOS window.

You can set your machine to start at a DOS prompt by altering the hidden file "MSDOS.SYS". Within Windows go to "My Computer" and go to the View Menu. Select Folder Options and then select the View tab. Select the option "Show all files".

Next look on the "C" drive for a file called MSDOS.SYS. Right click on it and select Properties. Unclick the box marked "Read Only" and close the Properties window. Then open MSDOS.SYS with Notepad, change the line reading "BootGUI=1" to read BootGUI=0". Save the change and close all the open windows. You may want to go back and recheck the Read Only attribute of the file and hide the system files again to prevent future problems.

The next time you start or restart the machine it will display the Windows 98 splash screen and then boot to a C: prompt. If you keep Trunker in a folder (directory) called Trunker you can write a little batch file to run Trunker from the C: prompt like this:

cls cd\ cd trunker trunker

Name this Trunker.bat and leave it loose on the root directory of the C: drive. Leave duplicates of it wherever you may end up being in DOS. This allows you to run Trunker by just typing in "trunker" from any prompt that this little batch file exists. I keep a copy in my Windows directory since some times I end up at c:/windows>, I also keep it in Trunker and elsewhere. This batch file clears the screen, changes to the root directory, then changes to the Trunker directory and runs Trunker.

Others have written batch files to automatically delete the 1234sys.txt and other default files Trunker develops when it can't find a system ID. I leave this be, and changed the system name in 1234sys.txt to "I haven't ID'd the system yet!"

Also be sure that you use a file called in your Autoexec.bat to set the trunker environment variables. I have a file on the c: drive called track.txt, and a line in the autoexec,bat that says:

set trackenv=c:\track.txt

Then be sure that your slicer pin, polarity, tracking radio (if used) and other variables as noted in the Trunker docs are set here.

If you mean you just want to view on the screen using one scanner, then the only difference is the variable trackenv.txt will not work if set in the autoexec.bat file in C: I had to set the variable by selecting "System Properties" from the control panel. Then select "Advanced" and at the bottom select "Environment Variables". Enter the variable here.

Like I said in my last post I have good accuracy until I try to use the second radio. If you only want to view the system and not listen to it this should work. You can also set the variable from a "Command Prompt" window, but it will only work for that window until it is closed.

Has anyone had luck making XP work with two radios? The other post wasn't specific about the setup except that it worked.

I thought I enabled Compatibility mode on my Trunker here (right- click-->Properties-->Compatibility), but I just checked it and I do not have it enabled.

To start Trunker in XP however, I have a batch file with the following in it:

set trackenv=c:\trackenv.txt trunker

My trackenv.txt file contains the following:

TRACKSCANPORT=com2 TRACKSCANBAUD=19200 TRACKSCAN=BC245 TRACKSLICERPIN=CTS TRACKSLICERPORT=com1 TRACKSCANPARK=147.3400 NOEMERGENCY=1 TRACKDIGITAL=1 TRACKSLICERMODE=normal TYPE2LURK=1 FILTERLOG=1 NEWRADIO=50 NEWGROUP=50 TRACKCOLORS=0,2,7,14,14,4

Of course that will vary because of different settings, etc.

Perhaps I'm not having any trouble because I upgraded from Windows98 to WindowsXP. You can try compatibility mode and see if that works. Bottom line: I've heard of several people running Trunker in WinXP fine. On the other hand, I've also heard lots of people having problems. Hopefully a Windows version will be available soon. Good luck. I got it working now. While in the Explorer window, I clicked on Tools and then Folder Options. I then clicked on the View tab and unchecked the box that says "Hide file extensions for known file types." Appearantly, when I named the file trackenv.txt, Windows mistook the ".txt" to be part of the file name, rather than the file extnsion. More than likely XP uses the NT form of environment variable setting. These should need to be set only once when done this way.

Clip from Win2kPro help file:

---

To add or change the values of environment variables

Open System in Control Panel. On the Advanced tab, click Environment Variables, then click the name of the user variable or system variable you want to change, as follows: Click New to add a new variable name and value. Click Edit to change a current variable name and value. Click Delete to remove a variable name and value. Notes

If you are not logged on as administrator to the local computer, the only environment variables you can change are user variables. To open a Control Panel item, click Start, point to Settings, click Control Panel, and then double-click the appropriate icon. Windows 2000 saves changes in the registry so they are available automatically the next time you start your computer. You may have to close and reopen running programs for the new settings to take effect. From: "Dewey" <dewey3@c...> Date: Tue Nov 13, 2001 4:52 pm Subject: RE: [trunker] Re: XP ?

I can not comment on XP since I'm not running, but I wrote a very short batch file that sets *and* unsets the variables some I can run Trunker effectively in Windows. When you look at the batch file, you will see that it sets *all* the variables for me, then calls Trunker. Once Trunker is terminated, the batch file unsets the variables. This has worked for me for years with no problems. I named the batch file TRNK.BAT, and created a Windows shortcut to it (the shortcut is also set so the DOS does not know that Windows is running). Here's the file.... I hope it helps:

Well if I go in and turn the com port off and then on it works fine. Then if I go to use it on another program such as my external modem it tells me that the comport is in use despite having exited from trunker normally.

Go in turn it off and back on and it works the external modem.

I looked at the power save registry edit but mine was already all "o".

I know this is not the computer thread but it is a pain in the butt when running trunker. I'm not sure if I posted my resolution to the COM port problem.

I broke down and called the Vendor (Dell) Great Support !!!!

They finally before going for a Mother Board replacement, said Re-Set your BIOS . Once we did that, all is well back here in Boston !! Date: Sun, 19 Oct 2003 15:33:01 -0000

Subject: Trunker and WinXP Part 34829334

Recently I have tried to use Trunker in Windows XP on 2 different computers. Using information from this forum's members and elsewhere I have had great success!

Computer #1 is a Dell Inspiron 1800 with a built-in Serial Port and dual PCMCIA slots. With a dual boot, I was able to run Trunker just fine from Win98 on a separate partition. I could use the built-in serial port for bith the slicer and the AR8000 using a special cable.

From WinXP I was unable to get the built-in serial port to work with a dataslicer and Trunker at all, but I was able to get Trunker to work with the Socket Dual IO PC Card serial port. I guess the drivers for the Socket Card work better with DOS applications than XP's drivers for the built-in serial port.

Following the adivice from this forum I added a line to the autoexec.nt file in the System32 directory that set the tracking variables by pointing to my track.txt file within the Trunker directory. (set trackenv=e:/trunker/track.txt). I used Com4 for the Slicer since the serial port card ended up with Com4 and Com5. The AR8000 second radio works fine off of the built-in serial port (Com1). I was unable to get both the slicer and the AR8000 to work off of a single com port in any NT based OS (XP or Win2K) but it works fine using separate ports. When connected to the same serial port the AR8000 goes to the Park frequency but the dataslicer sees no data.

With my old laptop running Win2K I was unable to leave Trunker running in the background since the serial port seemed to stop seeong data unless Trunker was in the front window. That issue has seemed to disappear, Trunker runs happily in the background, even minimized, with no loss of data decoding. It also sends the AR8000 to voice channels with no problems minimized or in the background.

On my little Sony Viao V505 that has no built-in serial port I also used the above tricks to get Trunker working, but of course I had some problems. I used the same serial port card as from my Dell and everything worked great. I then bought a new Socket Dual IO serial port card so that I could leave one laptop in the car without having to disassemble everything. Since the new card was an updated version it had different drivers. It took me a while to get it installed since the installer would barf when it came upon the old card's drivers. Since I didn't want to diddle with the Dell now that it was working fine I had my In-House IT Department (son) get those old drivers flushed out so the new card would work.

Now the Sony works just as good as the Dell. Since there is no built-in serial port I was able to use Com1 and Com4 on the Socket card, so that both my track.txt files are identical.

The next project is to get the Dell's built-in serial port to change to Com5 or 6 so I can put both the AR8000 and the slicer on Socket card so that both machines are consistant. My GPS works fine on a USB adaptor, so I will use that for both machines, thus I won't need to swap cords around all the time.

I had VERY similar problems when trying to run Trunker/Etrunk (as well as other DOS programs accessing the COMM port) on my Toshiba laptop. Sometimes the application would see the comm port, other times it wouldn't. I tried every power setting I could find, to no avail. Finally, someone on TrunkCom sent me the info to check the comm port's power saver setting in my registry.... yes registry. I fixed that, and have not had any problems since (that was over a year ago)!!!

First, do this at YOUR OWN RISK. Second, if you should do it, record your old settings so you can change them back if needed (like, if this is not the solution):

Run "Regedit", and drill down the following keys:

HKEY_LOCAL_MACHINE System Services VxD VCOMM

If "Enable Power Management" is set to anything other than 00 00 00 00 (four sets of zeros), change it to read 00 00 00 00. This turns off the Registry's power management to the comm port. Like I said, it was exactly what I needed.

BTW: to get to CMOS on a Toshiba laptop, hold down the ESC key while turning the machine on.

Dewey You'll also want to make sure it's not tied to the Ir port device. i had to turn off all power saving features and go into bios to turn off the IR and to configure Comm1. The com port was in power save mode, I would have to run something that called it directly to wake it up. I fixed that with the following registry hack: --- Start Run regedit H key Local Machine (click the +) System (click the +) Current control set (click the +) Services (click the +) Vxd (click the +) Vcomm (open folder) Enable power management (open file) change to all zeros (01 00 00 00 = power save mode on) save restart machine Microsoft Knowledge Base Article - 252184 MS-DOS-Based Programs Unable to Initialize COM Ports on Computers with ACPI Support The information in this article applies to: Microsoft Windows Millennium Edition Microsoft Windows 98 Second Edition This article was previously published under Q252184 If this article does not describe your hardware-related issue, please see the following Microsoft Web site to view more articles about hardware: http://support.microsoft.com/support/windows/topics/hardware/hwddresctr.asp

IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base: 256986 Description of the Microsoft Windows Registry

SYMPTOMS When you are running Windows 98 Second Edition or Windows Millennium Edition (Me) on a computer that supports the Advanced Configuration and Power Interface (ACPI) specification, MS-DOS-based programs that use the Extended Communication Service Int 14h function 05 do not work during the first attempt. To observe this behavior, use the Mode.com tool, type MODE COMx:19200, and then press ENTER. You then receive the following error message: Function not supported on this computer. NOTE: The information in this article is applicable only if you are able to start your computer to an MS-DOS prompt and you are able to run the preceding command successfully. If you receive an error message when you run the preceding command, your computer's Basic Input/Output System (BIOS) does not support the extended communication INT 14h function 05 command. For additional information about this issue, click the article number below to view the article in the Microsoft Knowledge Base: 119595 Function Not Supported on This Computer

CAUSE This behavior can occur because the virtual communication device (Vcd.vxd) incorrectly initializes the default state of the COM ports for MS-DOS virtual machines (VMs) when you start your computer because the COM ports have already been detected and powered off. The virtual COM ports are initialized with 0xFF for all of its states instead of the actual values of the port. Each time a new VM is created, the default state that was detected at startup is copied to the VM. Because the COM ports are trapped and virtualized, some of the responses to in/out commands are based on the default state at startup instead of the current state of the hardware. There are many in/out commands that non-virtualize the port. When this occurs, power is applied to the port, the current state is copied into the virtual settings, and the COM ports operate properly. RESOLUTION To work around this behavior, use either of the following methods: Method 1 Run the MODE command twice to properly initialize the port. Method 2 Disable the power management of the COM ports: Use Registry Editor (Regedit.exe) to locate the EnablePowerManagement value in the following registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\VCOMM

On the Edit menu, click Modify, change 01 to 00, and then click OK. Quit Registry Editor. STATUS Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. MORE INFORMATION This behavior does not affect 32-bit Windows programs and MS-DOS-based programs that program the UART directly, because in both of these cases power is applied to the COM ports and the COM ports are initialized properly.

Function Not Supported on This Computer The information in this article applies to: Microsoft Windows 95 This article was previously published under Q119595 SYMPTOMS Typing MODE COMx:19200 results in the following error message: Function not supported on this computer. CAUSE IBM PS/2-style computers support extended INT 14h services that allow the baud rate to be set up to 19200. MODE uses this extended function support to initialize COM ports on PS/2-style systems.

Most non-PS/2-class machines do not have a ROM BIOS that supports this extended functionality. WORKAROUND Rather than using MODE to set the baud rate, use an application that controls the COM port to set the baud rate. STATUS Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. MORE INFORMATION This information is true for previous versions of MODE.COM as well the version in Windows 95.
