E-BUS Modules to VCM-X E-BUS or RNE Controller Wiring
Figure 2: Multiple E-BUS Modules Wiring to Unit Controller Using the E-BUS Adapter (VCM-X E-BUS
Controller Shown)
Connecting Multiple E-BUS Modules
to the VCM-X E-BUS or RNE Controller
If using multiple E-BUS Modules, the E-BUS Adapter Board can
be used when the one HSSC E-BUS port on the VCM-X E-BUS or
RNE Controller is not enough.
Up to (2) E-BUS Modules can be connected to the E-BUS Adapter
Board’s HSSC E-BUS ports. The Unit Controller connects to the
third HSSC E-BUS port on the E-BUS Adapter Board.
See Figure 2 below for details when connecting multiple E-BUS
Modules to a VCM-X E-BUS Controller or RNE Controller.

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.
