How can I verify that my Pocket PC is receiving GPS signals?
Follow the appropriate set of instructions below to determine whether your Pocket PC computer is communicating properly to the GPS receiver. This process will help you to determine the serial port being used by the GPS.

Using Pocket PC 2003

The Pocket PC 2003 version may lead into dialing a number to check on the connection under the Start > Settings > Connections > Connections window.

To avoid this issue, an application named TTY can be used to perform the test between the GPS receiver and the Pocket PC.  The software and instructions on how to use it are listed below.

Download TTY

Once you have successfully downloaded TTY on your Pocket PC, follow these steps.

1. Go to File > Settings.
2. Choose COM1 for the COM PORT option.
3. Set the Baud Rate to "4800".
4. Set the Parity option to "None".
5. Set the Flow Control option to "RTS/CTS".
6. Set the Data Bits option to "8".
7. Set the Stop Bits option to "1".
7. Click on OK.

If the terminal does not generate any script, repeat Step 2 by selecting another COM Port.  Also, make sure that the settings from Steps 3-7 are the same.  Usually the GPS receiver can be found at any port, from 1 through 8.


Using Pocket PC 2002

Note – Make sure that Teletype GPS is not open when you attempt this process.  

Verify that your serial port is working.

Note: To use TeleType GPS you do not need to use modem connection. The only reason we give instructions regarding this set up is so that one can verify that the Pocket PC serial port is working.
a. Go to Start/Settings/Connections
b. Select Connections
c. Under Internet Settings select New
d. Enter the name GPS Test
e. Select the Modem tab
f. Select "New…"
g. Change modem to TeleType 1358 (if using Compact Flash GPS), or Comm1-Hayes compatible, (if using serial device)
h. Change Baud Rate to 4800
i. Tap Advance
j. Set Communications to 8, None, 1, None
k. Check "Use Terminal before connecting"
l. Check "Use Terminal after connecting"
m. Check "Enter dialing commands manually"
n. Tap OK
o. Tap Next
p. Uncheck "Cancel call if not connected..."
q. Uncheck "Wait for dial tone before dialing"
r. Tap Finish
s. Tap OK

Check to see that GPS Signals are coming through.
a. Go to Start:Settings:Connections:Connections:GPS Test (your new connection that you just created) for testing the GPS.  
b. Tap Connect, and tap OK. If you are presented with a dialog box asking for User ID and Password, leave all entries blank and press OK.
c. You should see NMEA GPS data displayed on the screen at this time. (If you are using a wired GPS system, such as those that plug into the bottom of the PDA, you need to insure that power is being provided to the GPS receiver).
d. If you receive an error such as IR send or receive failed, this is indicative of the fact that the PDA system registries have been scrambled and you must perform a factory reset. (Take care to backup important data as it will be lost during factory reset process).
e. Do not Restore your machine or you will have exactly the same problem as you had before the reset. You must manually re-install all programs and data.

Using Pocket PC (older OS)

Note – Make sure that Teletype GPS is not open when you attempt this process.  

1. Check GPS Status screen (Tools, GPS Status, Serial I/O). If you see type coming across the screen it's okay. If not proceed to step #2 below.
2. Verify that your serial port is working. (Note: To use TeleTypeGPS you do not need to use modem connection. The only reason we give instructions regarding this set up is so that one can verify that the Pocket PC serial port is working.
a. Go to Start/Settings/Connections
b. Select Modem

c. Click on New Connection
d. Change My Connection to GPS. Change Baud Rate to 4800.
e. Tap Advance
f. Set Communications to 8, None, 1, None
g. Check "Use Terminal before connecting"
h. Check "Use Terminal after connecting"
i. Check "Enter dialing commands manually"
j. Tap OK
k. Tap Next

l. Uncheck "Cancel call if not connected..."
m. Uncheck "Wait for dial tone before dialing"
n. Click Finish

Check to see that GPS Signals are coming through.
a. Go to Start:Connections:GPS (your new connection that you just created) for testing the GPS.  
b. Tap Connect. You should see NMEA GPS data displayed on the screen at this time.

Windows CE Handheld Computers (v2.11, 2.12)
Verify that the cable connections are appropriate and that your GPS receiver is properly configured for communicating to your hand held computer (HPC). You need to use the "Terminal" program found on your HPC. Here's how to check.

1. Activate "Terminal" program
(path is MyHandheld:Program Files:Communication:Terminal).

2. Make a New Connection

3. Change My Session to GPS

4. Change Telephone # to 111

5. Configure communications:
4800 baud, data bits=8, parity=none,
stop bits=1, flow control=none.

6. All check boxes should be On.
Manual dial... ON
Use terminal windows before...ON
Use terminal windows after...ON

7. Press OK

a. A blinking cursor indicates that the HPC is ready to receive signals from the GPS receiver. 
b. You should see NMEA GPS data displayed on the HPC screen at this time.

c. If you receive an error such as IR send or receive failed, this is indicative of the fact that the PDA system registries have been scrambled and you must perform a factory reset. (Take care to backup important data as it will be lost during factory reset process).
d. Do not Restore your machine or you will have exactly the same problem as you had before the reset. You must manually re-install all programs and data.
