ECU Connection to the DX System

The ECU can be connected to any other DX
Module existing in the DX system by way of the
two DXBUS connectors.

Environmental Control Connections

DB9 Connector

Any Environmental Control Device (ECD, an
input device that in some way effects your
surroundings) can be connected into your DX
system by way of the DB9 plug on the ECU
panel of connectors.

Connect your input device(s), as shown in
Figure 6, using a female DB9 socket.

Warning :

The switch contacts in the ECU are rated for 24V, 1A operation only.
The DB9 common contact is rated for 2A only. Do not exceed these
ratings in operation. In particular, 

do not connect the ECU to AC

mains.

For sample Mouse Mover connection to the ECU, see Figures 7 & 8.
