Interfacing Notes
It is important that the wiring of the cable between the Ashtech Z12 and the COM port is bi-directional, i.e. allows two-way data transfer, so that the Qinsy driver can request new ephemerides from the receiver.
System Configuration
The Ashtech Z12 GPS receiver can be configured for use by Qinsy by using the Screen 4 Mode Control.
INTERVAL [001.0] defines output rate of real-time MBEN (measurement) files;
MIN SVS [3] as well as ELEV MASK [00°] influence number of sent MBEN files.
