Communication Cable
Please note the following communication cable installation requirements and suggestions:
• The remote SmartHub is designed for use with
shielded, twisted-pair, communication cable. Toro
recommends R7162D or equivalent.
• More than one cable run can be connected to the Surge
Protection Unit (SPU, part #35-7353).
• A remote SmartHub communication cable can emanate
from another remote SmartHub 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 15 ).
• If the communication cable is routed in the same
trench as main power wires, or the SmartHub 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.
Steps:
1. Starting at the Surge Protection
Unit (SPU, part #35-7353), route
the communication (comm)
cable to each SmartHub leaving
enough cable at each location to
enable connection. See Figure
12 .
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 13 .
2. At the SmartHub, cut the
cable and pull both ends into the SmartHub
through the 3/4” (16mm) sweep conduit.
3. At the cable ends, strip the outer jacket and
inner insulation to expose the comm wires.
• SmartHub 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 SmartHub, plug comm line into the
modem port ( Figure 14) .
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.
