A
Splice one decoder blue wire to the 2-Wire path red wire; then
splice the other decoder blue wire to the 2-Wire path black wire.
If the decoder is NOT at the end of the two wire path then make a
three-way splice; one blue wire from the decoder to the two red
wires in the two wire path; then splice the other blue decoder
wire to the two black wires in the two wire path.
B
Splice additional wires from the decoder to the valve or valves to
be controlled, using a pair of the same color wires for each valve.
For example, Rain Bird FD-101 field decoders control a single
valve and have a pair of white wires for connection to the valve.
Other Rain Bird field decoders are capable of controlling multiple
valves. For example, the FD-601 has six additional pairs of wires
for connection to up to six different valves.

NOTE:
When using field decoders capable of controlling multiple
valves, note the wire color combination and decoder address
combinations on the side of the decoder. Be sure to connect
the wires to the different valves in the order you want your
valves controlled, and be sure to affix the decoder labels to your
Programming Guide in the same order.
C
Complete the splices to each valve by inserting the field decoder-
to-valve splices into an approved direct bury splice kit.

WARNING:
Use only 3M DBR/Y splice kits for all electrical wiring
connections to the 2-Wire path. Improper wiring can cause serious
damage to your controller or irrigation system.
D
For future troubleshooting or modifications, it is recommended
to leave an additional 3 feet of 2-Wire cable stored in each valve
box location.

NOTE:
For secondary wire run, the distance between the field
decoder and the solenoid (valve) can not exceed 450 feet (137
meters) using 14 gauge wire.
Typical Field Decoder Wiring
Master Valves and MV Decoders
Up to five master valves can be connected to the ESPLXD-ET controller
through field decoders attached to the two wire path. Master valves
are connected to field decoders using the same processes as described
previously. Be sure to attach the decoder barcode label to the
Programming Guide as a master valve decoder instead of a normal
station decoder.
