Communication Cable - Toro DEC-RS-1000-DR Installation And User Manual

Communication Cable

Please note the following communication cable installation requirements and suggestions:
• The remote gateway is designed for use with shielded,
twisted-pair, communication cable. Toro recommends
Paige P7162D or equivalent.
• More than one cable run can be connected to the Surge
Protection Unit (SPU, part #35-7353).
• A remote gateway communication cable can emanate
from another remote gateway connection.
• If additional communication cable runs are installed for
future system expansion, each cable wire pair must be
terminated with a 600 ohm resistor (Figure 11).
Steps:
1. Starting at the Surge Protection
Unit (SPU, part #35-7353), route
the communication (comm) cable
to each gateway leaving enough
cable at each location to enable
connection. See Figure 10.
If additional communication
cable is installed for future
system expansion, connect a 600
ohm resistor across the wire pair
at the end of the cable as shown
in Figure 11.
2. At the gateway, cut the cable and
pull both ends into the gateway
through the 3/4" (16mm) sweep
conduit.
3. At the cable ends, strip the outer
jacket and inner insulation to
expose the comm wires.
• Gateway connection: Attach a
Phoenix 3-hole connector.
• SPU connection: Attach a
Phoenix 3-hole connector.
• FIU connection: Attach a RJ-11
connector.
4. For the Gateway, plug comm line
into the modem port (Figure 12).
Remove the modem wire
connector(s) until the comm
cable has been tested. Refer to
the installation instructions
provided with the Central
controller for testing procedures.

• If the communication cable is routed in the same
trench as main power wires, or the gateway to decoder
module cables, a minimum of 12" (30.5cm) separation
is recommended to prevent voltage induction on the
communication cable. Check local codes for actual
requirements.
• Refer to the installation instructions provided with the
central control system for communication cable testing
procedures.
• If in-ground cable splices or repairs are required,
the connection must be properly insulated with a
waterproof splicing device. Using an appropriate
splicing kit, such as Scotchcast 82-A1 (or equivalent),
is recommended. Placing the cable splice in a small
valve box for protection and accessibility is a good
installation practice.
