3Part Three: Programming the Modem
3.1 CHANGING MODEM PARAMETERS - WINSETGMSK
v Modem parameters may be protected from change by a hardware link setting
described on page 12.
If you want to change modem parameters, they can be programmed by connecting a unit
to a standard PC serial port and using a program, WinSetGMSK.exe, which you can
download from the Wood & Douglas website, www.woodanddouglas.co.uk.
It is also possible to program the modem using command sequences of serial bytes. See
page 25.
Radio parameters are set separately: see page 13.
3.1.1 Adaptor Cable
The unit should be connected to the computer serial port using the type of cable shown in
Figure 8 on page 7. The RTS and CTS connections are essential in this case.
3.1.2 Obtaining and Running the Programming Software
v If you have already obtained and installed the software, go to step 3
1. Download the latest version of the programming software WinSetGMSK.exe from
the Wood & Douglas site on the internet. The URL (address) is:
www.woodanddouglas.co.uk
(In case of difficulty, contact Sales at Wood & Douglas, contact details on the last
page of this manual.)
2. Open the Zip file and run setup.exe, which will install the software for you.
3. Run the WinSetGMSK program. It will run in a normal window with both mouse
and keyboard support.
At this stage, the main window is displayed but behind a dialog shown in Figure 17.
