Addressing & Baud Rate
Figure 16: Address and Baud Rate Switch Setting
Controller Addressing & Baud Rate
Setting
Before applying power for the fi rst time, it is very important to
correctly address the controller and run through a few simple
checks.
If the VAV/Zone Controller is to operate as a Stand Alone con-
troller (not connected to any other HVAC unit or VAV/Zone
Controller(s)), the controller address switch should be set for
address 1. When the VAV/Zone Controller is to be connected
to other VAV/Zone Controllers on a communication loop, each
VAV/Zone Controller’s address switch must be set with a unique
address between 1 and 58.

NOTE:
The Power To The Controller Must Be Removed And
Reconnected After Changing The Address Switch Settings In
Order For Any Changes To Take Effect.
CAUTION:
Disconnect All Communication Loop Wiring From The
Controller Before Removing Power From The Controller.
Reconnect Power And Then Reconnect Communication Loop
Wiring.

* The CommLink 5 must be set to Low Speed if it is being used
on a system that includes the VCM-X Controller or older
generation of Orion Controllers.
** The CommLink 5 can be set to High Speed if is being used
on a system that only includes VCC-X, VCB-X, or GPC-XP
Controllers.
When programming the VAV/Zone Controller on a Stand Alone
or Interconnected System and you are asked to enter the Unit
ID, you would enter the address for the controller you wish to
program. When programming the VAV/Zone Controller on a
Networked System and you are asked to enter the Unit ID, you
would fi rst enter the MiniLink PD loop address for the loop the
VAV/Zone Controller Package is connected to and then enter
the VAV/Zone Controller’s address. See
Figure 16, below
for a
diagram depicting address switch settings.
Baud Rate Address switches 1 and 2 are used for the baud rate
selection. See
Figure 16,
below
for baud rate setting information.
