System Installation
6 VA minimum power and should be connected using 18
gauge minimum wire. In the Settings Menu, enter <63>
for the System Manager Address.
7. The Modular Service Tool SD 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. The
Communications setting must be set to Lo Speed
Network Mode.
8. Using 2 conductor shielded cable, connect from the
CommLink 5’s 3 wire communications connector to one
of the MiniLink PD’s 3 wire communications connector
marked “Network Loop”. The Loop switch on the back
of the CommLink 5 must be set to “Multiple”. The
CommLink only needs to be connected to one of the
MiniLink PDs on the system.
9. Using a modular cable, connect from each MiniLink
PD’s modular connector marked “Network Loop” to
the next MiniLink PD’s “Network Loop” modular
input connector using modular cable. Connect all the
remaining MiniLink PD’s in the same manner using a
daisy chain format.
10. Before powering up the controllers, set each VAV/
Zone Controller’s board address to a unique number
from 1 through 58. Address the VCM-X E-BUS
Controller at 59. Set MiniLink PD’s address from 1 to
60.
Loops Containing VCM-X E-BUS Controllers without VAV/
Zone Controllers
1. Connect all VCM-X E-BUS Controllers on the loop in
a daisy chain format using 18 gauge minimum,
2 conductor shielded cable for communications.
Install a separate 24 VAC, 8 VA minimum, transformer
for each controller and wire to its transformer 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. Connect 2 wire shielded cable from the CommLink 5’s
3 wire communications connector to the MiniLink PD’s
3 wire communications connector marked “Network
Loop”. The Loop switch on the back of the CommLink
5 must be set to “Multiple”. Use the 110 VAC/24 VAC
power supply furnished with the CommLink for its
power source.
4. Only one MiniLink PD on the system should connect to
the CommLink. Install a separate 24 VAC, 8 VA
minimum, transformer for each MiniLink PD and wire
to transformer using 18 gauge minimum, 2 wire cable
for power. Observe polarity on all boards. Each
MiniLink PD’s address switch should be set with a
unique address between 1 and 60.
5. Using a modular cable, connect from the each MiniLink
PD’s modular connector marked “Network Loop” to the
next MiniLink PD’s “Network Loop” modular input
connector using modular cable. Connect all the
remaining MiniLink PD’s in the same manner using a
daisy chain format.
6. 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 controllers is
located near the communications connector. The
Communications setting must be set to Lo Speed
Network Mode.
7.. The Modular System Manager is 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 remote location, run 18
gauge, 2 conductor shielded cable for communications
from one controller’s 3 wire terminal connector to one of
the MiniLink PD’s in the same manner using a daisy
chain format. The Communications setting must be set
to Lo Speed Network Mode.
8. The System Manager TS II utilizes a 3 wire
communication terminal block for connection to
any controller on the communications local loop that
has communication wire terminals. A separate
transformer is required for the System Manager TS II.
It has a 2 wire 24 VAC terminal block for connection to
a 24 VAC transformer. The transformer should be sized
to provide 6 VA minimum power and should be
connected using 18 gauge minimum wire. In the
Settings Menu, enter <63> for the System Manager
Address.
9. Address the VCM-X E-BUS Controllers from 1 to 59.
