Procedure
Step 1 Ensure that your residential network is in place before starting your syst em setup, including your Cisco
Controller: The Cisco I/O Extender requires a network connection to use all output ports as designed.
When connected, the Cisco I/O Extender can access web-based media databases and the Cisco
Controller.
Step 2 Connect the Cisco I/O Extender to the network: To connect using an Ethernet connection, plug the da ta
cable from the network connection into the Cisco I/O Extender RJ-45 port (labeled “Ethernet”).
Step 3 Power up the Cisco I/O Extender: Plug the Cisco I/O Extender power cord (provided) into the Cisco I/O
Extender power plug port and then to an electrical outlet.
Step 4 Connect the system devices: Follow the steps described in the “Connecting the Devices” on page 6 .

or IR Blaster” section on page 9 for more information.
4 Ethernet—One (1) RJ-45 port for a 10/100 BaseT Ethernet connection.
5 LED Indicators—Status, Data, Link, Power.
The LEDs on the front and back of the device are the same.
See the “Front View (LEDs and Other Features)” section on page 4 for details.
6 Reset Button—Recessed Reset button. Use the end of a paper clip to press and reset the device.
7 Contacts (8 sets, Bottom Row)—Pluggable terminal block connectors for eight (8) dry contact closures, logic input
connections, Door Contact Sensors, or Motion Sensors. Provides power for small devices (12 V), signal input (SIG),
return path (GND). The current, 1250 mA, is shared across all eight (8) sets of contacts.
8 Relays (8 sets, Top Row)—Pluggable terminal block connector for eight (8) normally closed or normally opened
switchable connections, such as a blind, a fireplace, or a projector screen. The set contains a connection for Normally
Opened (NO), Normally Closed (NC), and Common (COM). Relays are rated for 24 V 6 A maximum operation.

Connecting the Devices
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 (
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
Figure 4).
Figure 4).
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.

OL-27368-01
Note If you connect dry contact closure devices, such as door switches, connect the switch between +12V
(Power) and SIG (Signal).
Connect to the Contact Port
The Cisco I/O Extender provides four (4) contact ports for the pluggable terminal block provided.
See Figure 5 through Figure 7 to learn how to connect the device to a contact port.

Connecting the Devices
OL-27368-01
Note +12V and GND are used to power the Motion Sensor. SIG and GND are used to detect the state of the
Contact in the Motion Sensor.

Connect to the Relay Port
The Cisco I/O Extender provides eight (8) relay ports.
For most applications, attach one (1) wire to the common terminal, and the other to the normally open
terminal. The Relay switches close when the Relay is activated. The Cisco I/O Extender can support
applications that require a normally closed Contact.

Connect the Serial Ports
Configuring the Cisco I/O Extender
The Cisco I/O Extender provides four (4) DB9-style serial ports that use the RS-232 protocol. Connect
a device to the Cisco I/O Extender—for example, a receiver or disc changer—by aligning the pins,
inserting the plug and tightening the screws. Serial ports support many different baud rates. All ports
support Odd, Even and No Parity and hardware flow control.
Setting Up IR Emitters or IR Blaster
Your system may contain third-party products that are controlled through IR commands (usually using
remote controls). To provide a way for the Cisco Controller to control a device that only recognizes IR
commands, complete the following:
Procedure
Step 1 Plug the 3.5 mm connector end of one of the 4 IR stick-on emitters provided into an IR Out port on the
Cisco I/O Extender.
Step 2 Place the stick-on emitter end over the IR receiver on the Media Player, TV, or other target device to
drive IR signals from the Cisco I/O Extender to the target.
Configuring the Cisco I/O Extender
After you install and connect the hardware, use the Composer Pro software to configure the devices and
customize the system.
See the Cisco Smart+Connected Residential Installation and Configuration Guide for more information.

Resetting the Device
Resetting the Device
Procedure
To reset the Cisco I/O Extender for system recovery, perform the following steps:
Step 1 On the back of the device insert the end of a paper clip into the small hole (to the right of the Ethernet
connector).
Step 2 Power cycle the device by pressing and holding the Reset button for about 5-7 seconds and the Status LED
blinks orange. This action starts the recovery process.
Using the Identification Button
• To reset the device to the network defaults, power cycle the Cisco I/O Extender (using the power
button on the front of the device) and hold the Identification button until the Data, Link, and Power
LEDs are solid blue; immediately release the button.
• If during the boot sequence, the Status LED stays Orange, press and hold the Identification button
until the LED blinks Blue, and then release it.
