2.3. Wiring the RF Gateway to
a CPC Site Controller (I/O
Network)
Each Einstein or REFLECS site controller
that will receive a temperature value from an RF
Sensor must have an RF Gateway installed on its
RS485 I/O Network. For Einstein controllers,
this means the RF Gateway will be installed on
the I/O Network; for RMCC, BEC, BCU, and
other REFLECS products, the RF Gateway will
be installed on the COM A or COM D network.
2.3.1. Wire Connection
Using shielded three-conductor network
cable (Belden #8641 or equivalent), connect the
RS485 I/O Network wire to the three-terminal
connector on the RF Gateway board as shown in
Figure 2-3. For further information about how
RS485 networks are configured, refer to your
site controller’s user manual.
2.3.2. Setting the Board Number-
ing Dip Switch
The Einstein or REFLECS controller inter-
prets the RF Gateway board as a series of four
16AI Analog Input boards numbered in succes-
sion. Dip switches 1 through 4 set the first board
number used by the RF Gateway; when this
number is set, the RF Gateway will also use the
next three board numbers above the first board
number. For example, if an RF Gateway dip
switch is set to board number 3, the RF Gateway
will use board numbers 3, 4, 5, and 6 on the I/O
Network.

Note: The RF Gateway dip switch is mounted upside
down on the circuit board. Figure 2-4 and Figure 2-5
show the correct positions of the dip switches when
viewed upside down.
