Programmable Inputs and Outputs Wiring

Remote control with external pots and switches is pro-
vided with Programmable Inputs on a standard DB-25
connector on the rear panel. Programmable Outputs
are used to provide external LED indicators and to trig-
ger other events.
Examples of the wiring are shown below.

Control System Interconnections

In addition to a Windows
the DM84 can be controlled by external serial control
system using the RS-232 interface, such as those from
Crestron
RS-232 Port
