RS232 ADAPTER

The RS232 adapter provides four RS232 ports. The card contains two female DB26 connectors. An RS232 adapter cable converts the DB26 connection to two standard RS232 connections. Using the RS232 adapter cable, DB26 port #1 becomes RS232 port #1A and port #1B. You can configure each port pair (1A,1B or 2A,2B) for DTE (external clocking) or DCE (internal clocking), and each port supports data rates from 2.4 Kbps to 56 Kbps.

The RS232 supports network side connections, providing dedicated connections to other systems. The adapter can take advantage of slower speed analog lines by using standard synchronous analog modems. The RS232 also supports private network connections through a T1 multiplexer or a channel bank.
