These messages are of binary format. Users are unable to use a
terminal emulator program to control the GPS Receiver unit through the
CDU port. Special software supporting the TSIP protocol must be used
for this purpose.
When operating the GPS Receiver from a PC based Control-Display-Unit
using TSIP software, the cable link should be made with the RS232
ports, i.e. PC COM port to the GPS Receiver Command Channel port. A
special ’Y’ cable is required (NOT SUPPLIED) to connect both the
Command Channel and CDU ports simultaneously.
