The Site Controller SCM
The DPS Telecom Site Controller SCM mediates Modbus protocol traffic between Tridium JACE-545™ devices
(JACE). The Site Controller SCM converts the 9600 baud RS–232 JACE traffic to 1200 baud 202 for transport to
other Site Control Managers. Central to the Site Controller SCM design is an in-case integration of the Tridium
JACE-545™ device. In other words, the DPS Site Controller SCM and the JACE are inside a single chassis,
reducing the need for extra connectors and rack space.
Note:
the JACE-545 device is a trademark of Tridium, Inc.
The Site Controller SCM has two modes: master and slave. One master Site Controller SCM connects the JACE
Modbus interrogator to the 202 service channel. A slave Site Controller SCM links a JACE Modbus responder to
the service channel. A single Site Controller SCM master unit polls multiple Site Controller SCM slave units.

Power source connections
To connect the Site Controller SCM to a power source, follow these steps:
NOTE:
Do not apply –48V Power to the Site Controller SCM until all power Connections in Step 1
through Step 7 have been completed.
NOTE:
Use proper lug terminations on all power and frame ground connections to the Site Controller
SCM power input terminal strips.
NOTE:
The "A" and "B" power leads must be diversely run from the power input terminal strips to their
power source. One power lead must be routed on one side of the bay and the other routed on the
other side of the bay.
1.
Remove the fuse from the front panel of the Site Controller SCM and make sure that the power supply to the
unit is off.
2.
Remove the screw lug barrier plug from the front panel of the Site Controller SCM.
3.
Connect a –48 VDC line to the –48V terminal and a battery ground to the GND terminal of the screw lug.
Seat the barrier screws firmly, but be careful not to nick the bare wire. Repeat for power source B if you have
dual power inputs.
4.
Push the plug firmly back into its socket. Note that this connection is keyed and the plug must be properly
aligned within the socket.
5.
For earth/frame grounding, connect a copper wire with a ring terminal to the grounding post located on the
back panel of the Site Controller SCM. DPS Telecom recommends wire of at least 14 gauge. Place the ring
terminal between the two nuts and secure the nuts on the grounding post. Connect the other end of the wire to
an earth/frame ground.
6.
With the Site Controller SCM fuse still removed, turn on the power supply.
7.
Connect the black common lead of a voltmeter to the GND terminal and the red lead to the –48V terminal.
The voltmeter should read between –43 and –53 VDC. If the reading is outside this range, check your power
supply.
8.
Do not power the unit until all connections have been made.
9.
Insert the fuse to power the Site Controller SCM.
