118 ESP-LXD Controller
Install Station Expansion Modules
The ESP-LXD controller comes standard with 50 stations available. This
can easily be expanded by adding one or two optional ESP-LXD-SM75
Station Modules. Each station module adds 75 additional stations to
increase capacity to 125 or 200 stations.
Once your LXD Decoder module
is correctly installed, you’ll notice
that two additional module
slots are still available. Each of
these module slots can accept
one station module. Follow the
instructions to install one or two
station modules. The controller
will automatically recognize the
additional station capacity.

Connect Field Wiring
The ESP-LXD controller can support up to four 2-Wire connections.
The controller will manage multiple 2-Wire connections as a single
2-Wire path. The cable must be approved for underground use.
Rain Bird recommends use of MAXI Cable, #14 AWG, as your 2-Wire
communications cable.
Connecting the 2-Wire Cable

NOTE: If installing communications wiring for IQ Software and/
or ET Manager, do not install the communications cables in the
same conduit as the 2-Wire path wiring.
A
Strip away approximately 6 in (15,24 cm) of the cable’s outer
sheathing; then strip approximately 5/8 in (1,58 cm) of the
insulation away from the ends of the two inner wires. See Wire
Splices and Field Decoder Connections for more details on the
correct way to splice wire connections.
