GPS Receiver
Any commercially available GPS receiver should be suitable for use with the IPS, provided it can output the standard NMEA 0183 data strings "GGA" and "VTG". A receiver with differential capability (DGPS) is strongly recommended.
The GPS receiver may be connected to one of the Serial Multiplexer listener ports or to the PC serial port via a shielded RS-232 serial cable. The GPS receiver may also be connected to a RS-232 USB converter which allows you to convert GPS data into USB accessible data that can be input on any windows comport. In addition the RS-232 GPS data may be converted to an Ethernet UDP packet, however an Ethernet port must be opened in the IPS. Please see the Ethernet Configuration section of this manual for more information.
The operations manual for the GPS receiver should be consulted for details of the serial interface, and the procedures for enabling the required data strings. The output protocol should be set to the NMEA standard of no parity, 8 data bits and 1 stop bit.
