Digital Switch network wiring
Each Pow-R-Command Digital Switch (PRCDS) on the digital
switch network (DSN) is powered by the Pow-R-Command
controller. The DSN requires adding a PRC Power Injector
(PRCDSNPI) when more than 15 PRCDS are connected
or total DSN cable length exceeds 500 feet. Due to the
power being supplied to the switches on the same CAT-6
cable as the communication network, 23-gauge CAT-6
wiring is required.
CAT 6 RJ-45 connectors should be used to make
connections to each switch. All CAT-6 connections
will be made using the T-568B wiring standard. The
PRC1000E/2000E have an integrated RJ-45 jack in the
low-voltage connection compartment for connection to
the DSN network.

Switch addressing and network connections
Each PRCDS on the controller DSN requires a unique
address between 1-99. This is done using the two rotary
switches found on the back of each PRCDS. See
Figure 33
.
Network/power connections to each switch will be made
through the RJ-45 connections found on the back of each
Digital Switch. See
Figure 35
. These connections are daisy-
chained between each switch
