Pagina afdrukken1. DESCRIPTION
The product is a PC/104 carrier board that can be used to install a GPS module, a wireless modem,
and a land line modem. The GPS can be used simultaneously with either modem. Either but not both
modems can be used at one time. The board contains serial port circuitry connected to the PC/104
bus to provide communication links with the add-on modules.
Serial ports
2 RS-232 serial ports based on 16C2850 dual UART
Internal TTL-only signals, no transceivers for direct communication to on board UART to system
bus.
Jumper-selected addresses and interrupts
Interrupt sharing capability
Uses ISP Xilinx 9572 CPLD
Serial port 1 is fixed to GPS primary channel
Serial port 2 can be switched between modems and GPS auxiliary channel
Serial port connections for land line and wireless modems are in parallel since only one is used at
a time.
Serial port connections may also be routed from auxiliary serial port connector on Prometheus or
separate 20-pin header compatible with Emerald-MM-XT; these signals require transceivers to
convert to TTL levels on the board. It must be possible to disable the transceivers when they are
not in use.
