Connecting the Devices
Tip
Use Composer Pro to step through the connection process before or after the Cisco Controller is
physically connected.
Connect all applicable devices to the Cisco I/O Extender using one of the connection options described
in the
“Rear View (Input and Output Ports)” section on page 5
.
Pluggable Terminal Block Connectors
For the contact and relay ports, the Cisco I/O Extender makes use of a pluggable terminal block
connector—a removable plastic part that locks in individual wires (included).
To connect a device to the pluggable terminal block:
Procedure
Step 1
Insert one of the wires required for your device into the appropriate opening in the pluggable terminal
block you reserved for that device (
Figure 4
).
Step 2
Insert the wire as follows:
•
If using solid core wire, push the wire into the hole below the slotted retention tab, and ensure that
it’s tightly secured.
•
If using stranded wire, push the slotted retention tab in using a small flat-blade screwdriver. Insert
the wire into the hole below the tab, and then release the tab to secure the wire (
Figure 4
).

Insert Wires into the Connectors
For example, if you add a Motion Sensor, connect its wires to the following Contact openings—power
input to +12V output signal to SIG, and ground connector to GND. See the
“Connect to the Contact Port”
on page 7 or the
“Connect to the Relay Port”
on page 8 to learn how to connect the devices.
Step 3
Repeat Steps 1 and 2 for all wires required for your device.
