RF Extender

Introduction

Possible Set-ups

The RF Extender can be used in several situations:

• Your devices can be remotely controlled while the
RF Extender is placed in line of sight (situation A).

• The set-ups in situation A, B and C can
be combined. If you want to control
devices in different locations,
you have to place

• The RF Extender controls devices placed in
an adjacent room (situation B).

• The RF Extender is placed inside a closet
or a rack together with your devices

(situation C ).

You can operate all
RF Extenders with

Working Angle and Range of the IR blaster

Warning The IR signals sent out by the RF Extender always have to be able to reach the

receiving eyes of your devices. Make sure that the IR blaster (dark plastic window
on top of the RF Extender) is aimed at your devices.

Minimum distance:4 inches (10 cm)

Maximum distance: Approx. 16 feet (5m)

Before you install the RF Extender, you should decide which of the

set-up described on p. 1 apply to your needs.

It is also possible to place RF Extender with the IR blaster facing up. In this case,
the RF Extender can be placed at a distance and higher than the devices.
Make sure there are no objects between the RF Extender and the receiving eyes.

Mounting

The RF Extender can be mounted to a piece of furniture using the included
mounting plate and the 4 screws. Take into account the range and the working
angle of the IR blaster. Also make sure to place the RF Extender in a
central position aimed directly at your devices.

Warning It is adviced not to place the RF Extender inside or near a metal closet as

RF signals can be disturbed by metal objects.

Installation

To get optimal results, it is recommended to place the RF Extender horizontally
with the IR blaster facing up or down.

1 Attach the emitter around the receiving eyes of your devices. It is suggested

to adjust the location to find the most sencitive area before fix the emitter.

2 Plug the dual IR emitters into the RF Extender.

Note To avoid interference, the wires of the

emitters should be kept away from the

RF Extender as far as possible.

Connecting the Power Adapter

When connecting the power adapter it is recommended
that you plug the adapter into the RF Extender before
you plug it into the socket. When connected you will
see a red LED on the RF Extender.

How to use the emitters

Note To avoid interference, the adapter cable

The IR emitters can control devices the IR blaster cannot reach, for instance when
there is limited space in a small closet, it can be placed in a location as to where
the infrared receiver, can receive the signal.

Using the Dual IR Emitters

You can use the dual IR emitters as an alternative for the IR blaster.

Note The IR emitters can also be used in combination with the IR blaster of the

RF Extender. Both send out IR signals simultaneously. This allows you to operate
several devices using both the IR blaster and the IR emitters.

Settings

As the RF Extender ‘communicates’ with RC5200/RC9200, you have to set the
same Extender ID (identity) on both appliances. The settings depend on whether
you have a single RF Extender or multiple RF Extenders.

Single RF Extender

When you use only one RF Extender, you can accept the default setting for the
Extender ID (ID=0). Make sure your Remote Control is set to the same default
setting (see the RC5200/RC9200 User Guide for more details).

Multiple RF Extenders

If you want to operate several of your devices independently, e.g. grouped on
different locations, you will need multiple RF Extenders. When using several
RF Extenders, it is important to assign a unique Extender ID to each RF Extender.
16 Extender IDs (from 0 to 9 and from A to F) can be assigned.

1 Choose an Extender ID for the RF Extender by turning

the ID dial with a small screwdriver.

2 On the Remote Control, choose the same

Extender ID for each device controlled
by the RF Extender.

Refer to the RC5200/RC9200 User Guide for
more detail information.

3 Try to operate your devices with the Remote Control.

The red LED will blink when the RF Extender receives a correct command.

4 Repeat this procedure for every RF Extender.

RF Interference

If your devices are not responding to commands or if the red LED on the IR blaster
is blinking without sending commands, it might be possible that there is RF
interference. This can be the case when other RF appliances are operated nearby,
for instance at your neighbours.

When you notice RF interference, you have to choose another channel on your
RF Extender.

Troubleshooting

Troubleshooting

Devices do not respond properly

• Check if the power adapter is connected and the red LED is on.

• Check if the ID and channel numbers on the RF Extender match with the ID and

channel numbers on the ProntoPro Remote Control (see p. 6). Refer to the

RC5200/RC9200 manual for more details on the settings of the Remote Control.

• Check the placement of the RF Extender:

• Check the distance between the RF Extender and the remote control

(see p. 2).

• Check the range and the working angle of the IR blaster.

• Check if the RF Extender is placed in a central position relative to your

devices.

• Make sure that the distance between the RF Extender and your device is

at least 4 inches (10 cm).

• Make sure that the distance between the RF Extender and your device is

at most 16 feet (5 m).

• Make sure the IR signals between the RF Extender and the receiving eyes

of your devices are not disturbed by any objects.

• Check if metal objects, for instance a metal closet, wires or cables,

surrounding the RF Extender do not disturb the RF signals.

• If you are using the dual IR emitters, make sure they are connected

properly and that they are placed within range of the receiving eyes

(see p. 3).

• It might be possible that some commands cannot be sent out as RF signals.

In that case you will have to reconfigure RC5200/RC9200 to operate your

devices with IR signals again.

The red LED on the RF Extender blinks while you are not using remote
control

• This indicates RF interference. Another device in the proximity is sending out

RF signals. Change the channel (CH) on the RF Extender (see p. 4).

There is no red LED on my RF Extender

• Check if the power adapter is connected properly.

The dual IR emitters are no longer adhesive

• Replace the adhesive with a fresh piece of the 2-sided tape.

I cannot find the exact location of the device’s receiving eye

• Check the manual of the device.
When still in doubt, contact your supplier or the manufacturer.
