MSI-P600 PC/104 GPS Card w/Digital I/O
The MSI-P600 is a low cost, high performance global positioning system with NEMA 0183 and SiRF binary protocols. Software selectable NEMA protocols using the primary serial port are GGA, GSA, GSV and RMC with optional VTG and GLL. GPS data is selectable at programmable repetitive rates from 1 to 255 seconds, or on demand only.
Baud rates are selectable from 1200 to 38,400 with a default rate of 4800. The DGPS protocol is RTCM SC-104, version 2.00, types 1, 2 and 4. DPGS control data is entered through the secondary serial port. The serial ports are standard IBM PC compatible UARTs. The primary port is jumper selectable for COM1, COM3 or an offset address. Similarly, the secondary port is selectable at COM2, COM4 or an offset address. A time mark of 1 PPS is available as an interrupt or as input into modem status line DCD of the secondary UART for synchronizing events. The primary UART interrupt is also provided for allowing interrupt processing of GPS data. Interrupts are jumper selectable for IRQ3 thru IRQ7 and IRQ9. Four TTL level digital inputs are provided by status lines CTS and DSR of the primary and secondary UARTs.
Four TTL level outputs are provided by OUT1 and OUT2 of these UARTs. The card is supplied with an active antenna having a 5 meter (16.5 ft.) cable and a spacer kit.
A sample test program is supplied that illustrates programming of the UARTs for various NEMA protocols and data transfer rates. Operates from -40° to 80° C. Unit price $260.
