Installation and Wiring
VCM-X Modular E-BUS Controller to
Full Digital Module Wiring
The Full Digital Module directly connects to the VCM-X Modular E-
BUS Controller using a modular HSSC cable. The Full Digital Module
requires a 24 VAC power connection with an appropriate VA rating. See
Figure 4
below for wiring.
Any E-BUS Module can be connected to the E-BUS Controller’s E-BUS
port or can be daisy-chained together using HSSC cables.
NOTE:
Contact Factory for the correct HSSC cable length for
your application. Cables are available in ½ and 3 meter
lengths and 100 and 150 foot lengths.

WARNING!!
Observe Polarity! All boards must be
wired with GND-to-GND and 24 VAC-
to-24 VAC. Failure to observe polarity
could result in damage to the boards.
This Dip Switch Is
Not Used For This
Application
If Using One Module,
Set Addresses To Off.
If Using Two Modules,
Set Addresses
Consecutively.
