8-, 4-, or 2-Port RS-422/485 PC/104 SERIAL COMMUNICATION
K E Y F E AT U R E S :
■ 8, 4 or 2 independent asynchronous serial COM ports ■ Field selectable RS-422 and RS-485,
■ Programmable individual non-volatile base addresses
and IRQs simplifies installation
■ Operates as a standard COM port in all operating systems
independent for each port
■ Auto-RTS feature makes half-duplex RS-485
FAC T ORY OP T IONS:
■ 16850 UARTS with 128-byte FIFO ■ 0 to 70°C and -40 to +85°C versions available
communications effortless
■ Speeds up to 921.6K ■ Fixed bias and jumper selectable termination provided
on each transmit and receive channel simplifies cabling
■ Low power required: +5VDC at 80mA typical
The 104-COM-8S Series are eight, four, or two-port, asynchronous, serial communication boards that support both RS-485 and RS-422 communications. Ideal for POS, gaming systems, machine monitoring, military, and high-density networking applications, these boards may be installed in any system with PC/104 support. Ports are accessed via a 50-pin IDC type right angle connector. This board may be operated in two modes. In the Default Mode, the base address for the board is selected by jumpers and all of the channel addresses are sequential. Alternately, the addresses and interrupts of the individual channels may be stored in non-volatile memory on the board and loaded into programmed logic when the board is initially powered. Individual
interrupts for each ……
