Serial Communication Interface

The NPC-486E supports two serial ports, a primary and a secondary. These ports may be
configured as COM1 and COM2 of a standard PC/AT. The line drivers used conform to
the IEEE RS-232C standard. The secondary port also supports RS-485 signal levels.
Either port may be disabled if desired to accommodate an alternate serial device such as a
modem or fax.

8.1

Connectors

The connector for the primary port, J9, is a 10-pin, dual-in-line, male header. The
secondary port, J8, is a 14-pin, dual-in-line, male header.

The pin-out for the primary connector, J9, is:
