Introduction to the IO Extender

The Control4

®

 IO Extender opens up a whole world of options in the Control4 

system to control home theaters,  video devices, motion sensors, and other 
devices that use infrared (IR), serial, contact, and relay connections. 

The IO Extender serves well as the companion to the Home Controller HC-
1000 to expand output capability; in addition, the IO Extender provides flexible 
options for mounting in an equipment rack (1U) or on a wall.

To mount the unit on the wall, use the optional feet and keyholes on the bottom 
of the unit. These keyholes are designed to fit the screw spacing found on a 
standard U.S. double-gang box.

To mount the unit in a rack, install the included rack mount ears and install the 
device in the rack. The device can be mounted with the front facing outward, or 
optionally, it can be mounted on the equipment rack’s rear rails with the rear of 
the device facing outward for easier access to the input and output connectors.

The rack mount ears can be mounted to the bottom of the device with the ears 
at the front (for front rack mounts), or alternatively, with the ears at the back (for 
rear rack mounts).

Important Safety Instructions

1.  Read and keep these instructions.
2.  Heed all warnings.
3.  Follow all instructions.
4.  Do not use the apparatus near water.
5.  Clean the apparatus only with a dry cloth.
6.  Install the apparatus according to the manufacturer’s instructions.
7.  Do not install the apparatus near any heat sources such as radiators, heat 

registers, stoves, or other apparatuses (including amplifiers) that produce 
heat.

8.  Do not defeat the safety purpose of the polarized or grounding-type plug. A 

polarized plug has two (2) blades with one wider than the other. A ground-
ing type plug has two (2) blades and a third grounding prong. The wide 
blade or the third (3) prong are provided for your safety. If the provided plug 
does not fit into your outlet, consult an electrician for replacement of the 
obsolete outlet.

9.  Protect the power cord from being walked on or pinched particularly at 

plugs, convenience receptacles, and the point where they exit from the 
apparatus.

10. Only use attachments/accessories specified by the manufacturer.
11. Unplug this apparatus during lighting storms or when unused for long peri-

ods of time.

12. Refer all servicing to qualified service personnel. Servicing is required 

when the apparatus has been damaged in any way, such as the         
power-supply cord or plug is damaged, liquid has been spilled or objects 

have fallen into the apparatus, the apparatus has been exposed to rain or 
moisture, does not operate normally, or has been dropped.

13. This apparatus has no AC mains power switch. The power cable is the AC 

mains disconnect device.

WARNING!  

To reduce the risk of electrical shock, do not expose this 

apparatus to rain or moisture.

WARNING!  

This CLASS I apparatus must be connected to an AC 

mains socket outlet that has a protective earthing connection (i.e., third-
prong ground conductor).

 DO NOT DEFEAT THE PROTECTIVE 

EARTHING CONNECTION!

Mounting Options

Before you install the IO Extender, figure out how you want to install it. 

You can:

Place it on a flat surface

Mount it on the wall

Mount it on a rack—front facing or back facing

Flat Surface

Place the device on a flat surface, and connect the devices.

Mount on a Wall - New Construction

The device can mount to a 2-gang wall box. 

Mount the 2-gang wall box.

Hang the device on the two (2) screws in the wall box front side up.

Connect the devices at the bottom of the device.

Mount in a Rack

Install the IO Extender

To install the IO Extender, follow these general steps:

1.

Ensure that your home network is in place before starting your system 
setup, including your Controller

. The IO Extender requires a network 

connection to use all outlet ports as designed. When connected, the IO 
Extender can access Web-based media databases and the Controller.

2. 

Connect the IO Extender Controller to the network

. To connect to the 

Ethernet network, plug the data cable from the home network connection 
into the IO Extender RJ-45 port (labeled “Ethernet”) and the network port on 
the wall or at the network switch. 

3. 

Power up the IO Extender

. Plug the IO Extender power cord (provided) 

into the IO Extender power plug port, and then to an electrical outlet.

4. 

Connect the system devices

. Follow the steps described in the “Connect 

Devices” section that follows.

Configure the IO Extender in Composer
