preliminary PREFACE . . . . . . . . . . . . . ............................................................................................. . . . . . This manual is a guide to the proper configuration, installation, and operation of your MBSGPS PC/104 Interface. For setup and operation of the Novatel SSII or OEMV-1 Manuals included with this product. You can use your MBS-GPS-SS2-5HZ card in conjunction with other PC/104 expansion cards, tailoring your system for a wide variety of applications.
preliminary OEMV-1 3.3V GPS. Once the unit is configured and installed it is treated as three standard serial ports on the PC/104 stack. As an example, if the Data Port is configured for an address of 0x3F8 and IRQ 4 then the MBS-GPS is utilized simply as COM 1. Default operation is 16C550 mode with 16 byte FIFO’s. Wide FIFO enable is via software writes to special registers. Please refer to the XR16C2850 UART datasheet. This unit does not support flow control except on the EXT Serial Port.
preliminary 921,600 baud. The Novatel SSII-5Hz supports a maximum of 19,200 baud. The OEVM-1 supports up to 921,600 baud. Environmental -35° to 70° C operating. -40° to 90° C non-operating. RH 5% to 95%, non-condensing. Power Specification 5V +/– 5% at 100 mA maximum.. Antenna common mode output 50mA Maximum. Size 3.6 in. x 3.8 in x 0.5 in. 91.4 mm X 96.5 mm x 15.2 mm INSTALLATION . . . . . . . . . . . . . ............................................................................................. . . .
preliminary Address Selection Rotary Switches For flexibility with most SW and Development libraries this unit will support any valid address between 0x000-0x007 and 0x7F8-0x7FF. However, most platforms have limited IO space. Please refer to your host CPU IO Map for available IO space for this product. Most applications will use one of the common serial port addresses. The most common are: COM1 = 3F8, IRQ4, COM2 = 2F8, IRQ3 COM3 = 3E8, IRQ4 COM4 = 2E8, IRQ3.
preliminary Un-Inverted, I = Inverted. RTS1 Inverts or un-inverts the RS-232 1PPS signal output. Bit set = invert. DTR0 Inverts or un-inverts the TTL 1PPS signal output. Bit set = invert. STATUS MONITORING . . . . . . . . . . . . . ............................................................................................. . . . . . Overview Several status features are available. These are provided to monitor the 1PPS timing pulse from either the GPS or the AUX 1PPS source.
preliminary NOTE If AUX PPS is selected then the these features will work upon the AUX signal instead of the GPS signal. The AUX is primarily used for software development of systems requiring a 1PPS interrupt where no GPS signal is available as GPS systems may not provide a 1PPS without a valid fix. TABLE 1 SIGNAL FUNCTION STATUS LINE FUNCTION DTR1 Reset Line for GPS or Ext device at J7 CD1 TTL Discreet input, active low, J6.4 DSR1 TTL Discreet input, active low, J6.
preliminary PPS IO Connector, J6 Terminal Block J6 is the IO for the 1PP signal. The pinouts are as follows: J6.1 1PPS Output. This represents the 1PPS output in RS-232 level. This signal depends upon the source and polarity selection as described previously. J6.2 TTL level 1PPS output. It is identical to J6.1 except it is TTL level and can be inverted independently of J6.1. J6.3 This is the AUX PPS input. This input accepts RS-232 level signals.
preliminary J7, EXT RS-232 Serial Port J7 is a standard 16C850 128 byte FIFO serial port with the exception that it supports baud rates up to 921 kbaud 1. 2. 3. 4. 5. 6. 7. 8. 9. 10.
