Connect a null-modem cable from the PC’s serial port to the XL-GPS’s “SERIAL I/O” port.

If needed, configure your PC’s terminal emulation program to match the serial port settings above (9600,
8, N, 1). Set Flow Control to “None”.

One terminal emulation program, HyperTerminal, is usually found in Microsoft Windows under
Programs – Accessories

or Programs – Accessories – Communications.

Initiate a serial port connection between the terminal emulation program and the XL-GPS. (The Serial
Port connection does not require you to log in.)

Once connected, press the Enter key on your keyboard to get a command prompt.

From the command prompt, “>”, you can use the functions described in the “Function Reference” section
of the XL-GPS User’s Guide and Reference Manual. The ‘Command Line’ sub-sections provide
instructions and examples.

Troubleshooting Tip:

If the terminal emulation software has trouble displaying XL-GPS responses

(looks like the unit doesn’t respond to inputs), add a 1 ms/character delay to the software’s serial port
settings.

Connecting to the Network Port

The network port provides remote access to the XL-GPS’s command line interface. Complete the
following steps to connect to the network port.

Use function

F100 – Network Port Configuration & XL-GPS Firmware (page 74)

, or

F100 IP – IP

Address (page 76)

, to obtain the XL-GPS’s IP address.

Open a telnet session from your PC to the XL-GPS.

In Windows, click Start – Run, enter telnet ###.###.###.### (where the #s are the XL-

GPS’s IP address), and click OK.

Open a telnet session using a program such as HyperTerminal, TeraTerm Pro, or Minicom.

Consult the program’s documentation for instructions.
