2.3 Configuring the CPU/System Controller Board
The CPU/System Controller board is situated on the right side of the
Process I/O board; the combined assembly mounts vertically on edge on
the inner left side of the enclosure. To configure the CPU/System
Controller board, you need to set some switches and jumpers.

Damage WILL occur to
the CPU if the Ethernet
network is connected
to connector J2!
CAUTION:
Solar Pwr. In and Aux. Power Out
are not available on units equipped
with an Ethernet Port.
Ultra Low Power CPU/System
Controller Bds. don’t have an
Ethernet Port.
NOTE:
Do Not Connect a 24V Solar Panel
to Connector TB1-1 & TB1-2!

NOTE: Carefully
examine DIP
switches to verify
proper ON/OFF
position. Different
versions of the
board may have
different switch
positions.
