Product: VRM-CG2 -

The VRM-CG2 CompactPCI 3U GPS Receiver Module is provided with a high performance receiver engine continuously tracking all satellites in view for a time accuracy better than 1us and horizontal accuracy better than 3m. The receiver is compatible with passive or active antennas and supports the NMEA-0183 data protocol, thus allowing nearly any GPS application program to be used with it.

Features:

- Board Form Factor: 3U Eurocard (100 x 160mm²), front panel width 20.3mm (4HP)

- Serial interfaces: Device: 16C550 compatible Quad PCI UART Oxford OXmPCI954 asynchronous serial protocol:
1 startbit; 7 or 8 databits; 1 or 2 stopbits; optional odd/even parity; bitrates up to 15Mbps
SP1 (internally): SP1/SP2: typical settings for GPS operation SP1=4800Baud (GPS NMEA-0183), SP2-9600Baud (DGPS RTCM SC-104)
SP2 (externally and internally): SP2 front panel connector: PC compatible D-SUB connector 9-pin male, to be used either as DGPS input or as universal serial COM port, ESD protection 15kV, RS-232E transceiver can be disabled by removing jumper J-SP2 (option)
SP3/SP4: on-board pin headers suitable for attachment of CU7-RS485 and CU8-RS232 PHY-modules (option)
Serial driver software (COM port emulation) available
