5 Power up the IO Extender. Connect the power cord to the
extender’s power plug port (or connect the Ethernet cable if
powering over PoE+) and then into an electrical outlet.
Note: The Ethernet network should be installed before you
install the IO Extender.
Installation Guide
Note: If powering the IO Extender with AC power, we
recommend that you connect any external devices (serial, IR,
contacts, and relays) first, before powering up the IO Extender.
• Composer Pro is required to configure this device. See the Composer
Pro User Guide ( for details.
• The IO Extender V2 requires Control4 OS 2.9 or newer.

Control4® IO Extender V2
Model number
The Control4® IO Extender V2 enables a Control4 system to control
home theaters, video devices, garage doors, motion sensors, and other
devices that use infrared (IR), serial, contact, and relay connections.
The IO Extender serves well as the companion to the EA Series of
entertainment and automation controllers to expand input and output
capabilities of a Control4 system.
The IO Extender V2 adds the ability to power the device by PoE+ to
simplify installation and provide power and network connectivity over a
single CAT5e/CAT6 network cable.
10/100BaseT compatible
Inputs / Outputs
8 IR out—5V 27mA max output
4 DB9 ports
8 contact sensors—30VDC maximum input
12VDC 1.25A maximum output
8 relays—AC: 36V, 2A; DC: 24V, 2A maximum
100-240 VAC, 60/50 Hz or
PoE+—up to 25.5W, IEEE 802.3at-2009
In addition, the IO Extender V2 provides flexible options for mounting
in an equipment rack (1U) or on a shelf. The included rack ears may
be installed at the front or back of the IO Extender V2 for maximum
installation flexibility.

To attach the rack ears to the IO Extender:
1 Remove the two screws in each of the rubber feet on the bottom of
the extender.
2 Remove the rubber feet and place the rack ears. The rack ears can
be positioned for front or rear rack mounting.
3 Use the screws from the rubber feet to secure the rack ears to the
The IO Extender provides four DB9 serial ports. The serial ports support
many different baud rates (acceptable range: 1200 to 115200 baud for
odd and even parity).
Additional resources
Using the included rack ears, the IO Extender can easily be mounted in
a rack for convenient installation and flexible rack placement.

Installing the IO Extender
To install the IO Extender:
1 Ensure that the home network is in place before starting system
setup. The IO Extender requires a network connection to use all of
the features as designed.
2 Mount the extender in a rack or stacked on a shelf. Always allow
plenty of ventilation. See “Mounting the IO Extender in a rack” in
this document.
3 Connect system devices. Attach IR, serial, contact, and relay
devices as described in “Connecting the serial ports,” “Connecting
the contact ports,” “Connecting the relay ports,” and “Setting up
IR emitters.”
4 Connect the controller to the network. Connect an Ethernet patch
cable to the RJ-45 port and to the network port on the wall or at
the network switch.
Note: If powering the IO Extender with a PoE+ connection, we
recommend that you connect any external devices (serial, IR,
contacts, and relays) first, before powering up the IO Extender
with the Ethernet PoE connection.
1 To configure a port’s serial settings, connect the driver’s RS-232
connection to the IO Extender serial port in the Connections tab in
Composer Pro.
Connecting the driver to the serial port will apply the serial settings
contained in the driver file to the serial port. See the Composer Pro
User Guide ( for details.
Setting up IR emitters
The IO Extender provides eight IR ports. Your system may contain thirdparty products that are controlled through IR commands. The included
IR emitters can send commands from the controller to any IR-controlled
1 Connect one of the included IR emitters into an IR OUT port on the
IO Extender.
2 Remove the adhesive backing from the emitter (round) end of the
IR emitter and affix it to the device to be controlled over the IR
receiver on the device.
Pluggable terminal block connectors
For the contact and relay ports, the IO Extender makes use of a
pluggable terminal block connector, which is a removable plastic part
that locks in individual wires (included).
To connect a device to the pluggable terminal block:
1 Remove the terminal block from the back of the IO Extender.
Note: The COM, NC, and NO terminals are used for relay
devices (outputs or something to control). The +12, SIG,
and GND terminals are used for contact devices (inputs and
2 Insert the wires into the appropriate holes and secure the wires by
tightening the screws.
3 After securing all of the wires in the terminal block, re-insert it into
the appropriate slot in the IO Extender.

Connecting the relay ports
The IO Extender provides eight contact ports for the included
pluggable terminal blocks. See Figures 3-5 for examples on how to
connect common devices to the contact port.
Figure 3. Connecting a dry contact (door sensor)
The IO Extender provides eight relay ports for the included pluggable
terminal block. With most applications, attach one wire to the COM
terminal and the other to the NO or NC terminal. The relay switch closes
or opens when the relay is activated.
Use Auto Discovery and SDDP to add the driver to the Composer
project. See the Composer Pro User Guide for details.
