Note: USB Port:
To make music saved to a USB drive
available to the system, use the USB port on the back
of the System Controller. The USB port is only for
music storage use and USB updates. You
cannot
use
it to connect the PC directly to the System Controller.
Connections
Connect all applicable devices to the System Controller
using one of the available connection methods
including those described on Table 1, “Connection
Worksheet for System Controller”. Connect all
applicable devices to the System Controller. The
following sections provide guidelines on making the
various connections, including:
•
Using Pluggable Terminal Block Connectors
•
Using BACnet port
•
Connecting to the Relay Port
•
Setting Up IR Emitters
•
Using USB Port to Set up External Storage Device
•
Using Video Sense Loops
Using Pluggable Terminal Block Connectors
For the Contact, Relay, and BACNET ports, the System
Controller makes use of a pluggable terminal block
connector—a removable plastic part to lock in
individual wires. This connector is included.
To connect a device to the Pluggable Terminal Block:
1.
Insert one of the wires required for your device into
the appropriate opening in the Pluggable Terminal
Block you reserved for that device (refer to Table 1
on page 4).
2.
Lower the openings latch until it locks the wire in
place.
3.
Repeat Steps 1-2 for all wires required for your
device.
Using BACnet/FLBus ports
The System Controller provides one BACnet® Network
port (labeled RS-485/FC-Bus as a subset of the
pluggable terminal block provided). See the following
figure to determine how to connect to this port.
Figure 1:
BACnet (RS-485/FC Bus) Port
For example, to install a BACnet Networked
Thermostat:
1.
Install the BACnet® Networked Thermostat and
wire the thermostat’s MS/TP Communications Bus
according to documentation provided and the MS/
TP Communications Bus Technical Bulletin (LT-
12011034).
2.
Connect the communication wires from the
thermostat to the System Controller as follows.
Connecting to the Relay Port
The System Controller provides one relay port as a
subset of the pluggable terminal block provided.
Figure 2:
Relay Port
Attach one wire to the common terminal and the other
to either the normally open terminal or the normally
closed terminal.
The relay switch closes when the relay is activated.
The System Controller can support applications that
require either a normally closed contact or a normally
open contact.
