4. External IR transmitters
There are a variety of external transmitters available with 3,5mm jacks.
4.1 stick on minitransmitters
The minitransmitters can be sticked directly to the IR receiver of the your devices.
Please note:

The transmitter casing is not transparent all the way around. The transmit-
ters will only work when the paper of the sticker is removed.

Range is limited to 20-30cm (~1ft). The transmitters should be sticked
directly to the IR receiver.

Individual control of multiple external transmitters is not possible with the
IRTrans devices covered by this handbook.

Standard cable length is 1,8m (~6ft). Cables may be extendet to up to 5m
(~15ft). Longer cables may cause signal distortions.

Important: When using external high power transmitters there is a jumper
to enable full power. This jumper must be removed when using minitrans-
mitters.
4.2 external high power transmitters
The external high power transmitters are equal to the built in IR LEDs. They are
available in a high frequency version as well (455kHz). The high frequency trans-
mitters can be recognised by clear LEDs. High power transmitters can be
connected to all of the IRTrans devices.
Cables should not be extended beyond standard length (1,8m~6ft). Longer
cables lead to distorted IR signals.
For using external high power transmitters a jumper has to be set inside the IR-
Trans. The following pictures illustrate the position of this jumper:
The jumper must not be set when using stick on minitransmitters!
