3. The Modular System Manager comes supplied with a 12
foot modular cable with a modular connector on one end
and stripped wires on the other. Run 18 gauge, 2 conductor
shielded cable for communications from the controller’s 3
wire communications terminal to a junction box. Run 18
gauge minimum, 2 wire, power wires from a separate 24
VAC, 6 VA minimum transformer into the junction box.
Splice the modular cable to the communications and power
wire inside of the junction box by making solid
connections, using wire nuts or butt splice connectors. See
the wiring diagram in this section for correct wiring color
coding and connection.
4. If a CommLink is used for a computer interface, connect
communications using 18 gauge, 2 conductor with shield
cable. Connect from the controller’s 3 wire
communications connector to the CommLink’s 3 wire
communications connector. For this type of system, the
CommLink needs to have its internal jumper set to
“Single”.
5. Use 18 gauge minimum, 2 wire cable for all 24 VAC power
wiring. Be sure to maintain polarity on all boards. If a
CommLink is connected , use the 110 VAC/24 VAC power
supply furnished with the CommLink for its power source.
6. Before powering up the controller, set the desired board
address on the controller (usually 1).
Interconnected Systems
See the “Interconnected System Wiring”on pages 9 and 11 of this manual
for detailed wiring diagrams. Also see pages 28 and 29 for wire and
transformer sizing information. You should review these diagrams be-
fore attempting connections or powering up the controller or interface
devices.
1. Connect all controllers in a daisy chain or star ring format
using 18 gauge, 2 conductor shielded cable for
communications. Install separate 24 VAC, 8 VA minimum,
transformer for each controller and wire to transformers
using 18 gauge minimum, 2 wire cable for power. Observe
polarity on all boards.
2. The Modular Service Tool will connect to any of the
controllers using the supplied cable with DIN connectors
on both ends. The connection point on the controller is
located near the communications connector.
3. The Modular System Manager comes supplied with a 12
foot modular cable with a modular connector on one end
and stripped wires on the other. If the Modular System
Manager is to be mounted in a remote location, run 18
gauge, 2 conductor shielded cable for communications
from the controller’s 3 wire communications terminal to a
junction box. Run 18 gauge minimum, 2 wire,
power wires from a separate 24 VAC, 6 VA minimum
transformer into the junction box. Splice the modular cable
to the communications and power wire inside of the
junction box by making solid connections, using wire nuts
or butt splice connectors. See the wiring diagram in this
section for correct wiring color coding and connection.
4. If a CommLink is used to provide for connection to a
computer interface, connect communications using 18
gauge, 2 conductor shielded cable. Connect from one of the
controller’s 3 wire communications connectors to the
CommLink’s 3 wire communications connector. For this
type of system, theCommLink needs to have its internal
jumper set to “Single”.
5. Use 18 gauge minimum, 2 wire cable for all 24 VAC power
wiring. Be sure to maintain polarity on all boards. If a
CommLink is installed, use the 110 VAC/24 VAC power
supply furnished with the CommLink for its power source.
6. Before powering up the controllers, set the board addresses
from 1-60.
Networked Single Loop Systems
See the “Networked System - Single Loop Wiring” on pages 12 through
16 of this manual for detailed wiring. Also see pages 28 and 29 for wire
and transformer sizing information. You should review these diagrams
before attempting connections or powering up the controller or interface
devices.
Loop Containing VCM Controllers Only
1. Connect all controllers in a daisy chain or star ring format
using 18 gauge, 2 conductor shielded cable for
communications. Install separate 24 VAC, 8 VA minimum,
transformer for each controller and wire to transformers
using 18 gauge minimum, 2 wire cable for power. Observe
polarity on all boards.
2. Connect 2 conductor shielded cable from one of the
controller’s 3 wire communications connector to the
MiniLink PD’s 3 wire communications connector marked
“Local Loop”. Use 18 gauge wire for power and observe
polarity on all boards.
3. If only a CommLink II is used, connect 2 conductor
shielded cable from one of the controller’s 3 wire
communications connector to the CommLink’s 3 wire
communications connector. If only the CommLink II is
used, the CommLink’s internal jumper must be set to
“Single”. Use the 110 VAC/24 VAC power supply
furnished with the CommLink for its power source.
4. If both the MiniLink Polling Device and the CommLink II
are used, connect 2 conductor shielded cable from one of
the controller’s 3 wire communications connector to the
MiniLink PD’s 3 wire communications connector marked
“Local Loop”. Connect 2 wire shielded cable from the
CommLink’s 3 wire communications connector to the
MiniLink PD’s 3 wire communications connector marked
“Network Loop”. When a MiniLink PD and a CommLink
are used, the CommLink’s internal jumper must be set to
“Multi”. Install a separate 24 VAC, 8 VA minimum,
transformer for the MiniLink PD and wire to transformer
using 18 gauge minimum, 2 wire cable for power. Observe
polarity on all boards.
