Interfacing Notes

It is important that the wiring of the cables between the DSM and the PC COM port is bi-directional. Every time QINSy needs new ephemerides (e.g. at initialisation or with new satellites), it will ask the receiver for it.

Port B (Control) is designed for RS-232 data connections and is reserved for TSIP input and output. Only Port B lets the QINSy System Configuration, control, and transfer raw GPS data using the TSIP interface.

The wiring of the 9-pin control port B of the Trimble DSM receiver (using the DSM adapter cable to disable hardware flow control) to a 9-pin or 25-pin multiple COM interface board (e.g. Digi 8e) must be as follows:
