DL340 CPU Port Pinouts
The DL340 CPU has two built-in
DirectNET slave ports under the hinged
cover.
The ports are limited to RS232C
communication, so you have to use an
RS232C/RS422 converter for multi-drop
connections. This port is an RJ11
(handset connector) phone jack. The
DirectLOGICE Universal Cable Kit
(FA–CABKIT) can be used if you do not
want to create a phone jack connection.

Ports 1 and 2
