Channels for each of four devices can be enabled or disabled via the configuration register of the devices.  Conversion times are approximately 800ns to 2200ns for 1 to 8 channels, respectively, of each device. Since conversions are simultaneous, all four devices are converting at the same time for a maximum time of approximately 2200ns for all 32 channels. .

The card is I/O mapped using 16-bit addressing to select the input channels and device status.  Option jumpers are provided for specifying the card base addresses A8 thru A15 and interrupts IRQ2 thru IRQ15.

MSI-P602 PC/104 Trimble Lassen iQ GPS Card with Digital I/O

The MSI-P602 
is a low cost, high performance global positioning system which uses the Trimble Lassen iQ module. It provides 12-channel GPS functionality that is fully compatible with Trimble’s popular Lassen SQ module using Trimble’s FirstGPS® architecture which delivers complete position, velocity and time (PVT) solutions for the host application. It features two GPS signal sensitivity modes: Standard and Enhanced. With Enhanced mode enabled, the module automatically switches to higher sensitivity when satellite signals are weak. The module also supports TSIP download of critical startup information for fast acquisition. This aided GPS (A-GPS) startup provides hot start performance for each power-up. The module supports the four most popular protocols: DGPS (RTCM), TSIP (Trimble Standard Interface Protocol), TAIP (Trimble ASCII Interface Protocol) and NMEA 0183 with an MTBF (mean time between failures) figure of 60 years.

The card provides two serial ports for processing the GPS data. The primary port gives TSIP input and output data at a default BAUD rate of 9600. This port is also selectable for the TAIP protocol. The secondary port provides DGPS (RTCM) input and NMEA output at a default BAUD rate of 4800. Software selectable NMEA protocols using the secondary serial port are GGA (default), GLL, GSA, GSV, RMC, VTG (default) and ZDA. Baud rates are selectable from 2400 to 38,400. The DGPS protocol is RTCM SC-104.

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 85° C.
