Note
The Programmable Terminal cannot be connected using a peripheral port con-
nection when communicating via a 1:1 NT Link.
Application Procedure
Setting communications.
Connecting the cables
Use the settings in the PC Setup (DM6645 to DM 6649) for
RS-232C communications.
(Turn OFF the Communications switch on the CPM2A’s CPU
Unit or pin 1 of the DIP Switch on the CPM2C’s CPU Unit.)
Connect to a Programmable Terminal.
The CPM2A’s communications are controlled by the communications switch on
the front of the CPU Unit and the CPM2C’s communications are controlled by
the DIP switch on the front of the CPU Unit.
