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.

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

8, 4 or 2 independent asynchronous serial COM ports

Field selectable RS-422 and RS-485,

independent for each port

Auto-RTS feature makes half-duplex RS-485

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
