To terminate the RS-485 bus,
jumpers J12 and J11 should be
across pine 1 & 2. The default
position is un-terminated and
jumpers are across pins 2 & 3.
Jumpering across pins 1 & 2 of J1
enables lithium backup of RAM
memory. If lithium backup is
disabled, powering the unit down
will cause a Cold Boot.
If the Security Switch is ON the
proper Security Code must be
entered in PCCU or user will be
unable to connect to XRC
Controller Board and configure
the unit.
