1. IRTrans Ethernet
The IRTrans Ethernet is an IR Transceiver with network interface.
Basic features are:
Receive an transmit IR
1 output fo external IR transmitter
1 input for external IR receivers
10/100 MBit network interface
Webinterface for configuration
IRTrans devices with the optional IR database offer additionally:
128k IR database (sufficient for approx. 1000-1500 IR commands)
Use withour IRServer
128k flash memory for own html pages
IRTrans devices with the optional 2X option:
2nd independent IR output (stereo jack output)
1.1 Connections
On the back there are:
Ethernet connector
5,5/2,1mm connector for power supply
Output for external IR transmitters
On the front there are 4 IR LEDs, 1 IR receiver and a 3,5mm jack to connect ex-
ternal IR receivers.

1.2 Power supply
The IRTrans Ethernet is powered by an external power supply. It must deliver 8-
16V and 300mA per IRTrans device. The positive lead is wired to the center ter-
minal of the 5,5/2,1mm hollow connector.
A 5,5/2,5mm connector may fit as well but will not have reliable contact.
The IRTrans will encounter seemingly inexpliccable reboots.
When using external high power transmitters the power supply should be
capable of delivering 500mA.

2. IRTrans Ethernet PoE
The IRTrans PoE is mostly identical to the IRTrans Ethernet devices. It is availab-
le with IR database and 2X option as well.
Differences to the IRTrans Ethernet:
Power supply over Ethernet (PoE). Alternatively an external power supply
may be used.
2x option with own connector
2.1 Connections
On the back there are from left to right:
Ethernet connector
2nd output for external transmitter: 3,5mm jack
1st output for external transmitter: 3,5mm jack
above: connector for external power supply
status LED of the power supply
The left 3,5mm jack is always built into the devices but deactivated without 2X
option.

2.2 Power supply
The IRTrans Ethernet PoE may be supplied with power by an IEEE 802.3af con-
formal Power over Ethernet switch. According IEEE802.3af the power may be
supplied by a free conductor pair as well as by a data pair.
Older switches not conforming to IEEE802.3af may not be usable to power the
IRTrans PoE.
For an external power supply there is a 5.5/2.5mm hollow connector. The exter-
nal power supply should be capable of delivering 4,5-6V with approximately
300mA. The positive lead must be wired to the center terminal.
If there is power available either via PoE or by external supply the blue
LED next to the power connector will be lit´.
The IRTrans Ethernet PoE requires a different voltage power supply
compared to other IRTrans modules. For this reason the power connec-
tor is 5,5/2,5mm.

3. Ethernet interface
The Ethernet interface allows to integrate the IRTrans in any IP based Ethernet.
The IP stack runs on a Freescale MC9S12NE64 processor.
The ethernet interface is configured to use 10MBit/s per default. 100MBit/s is
possible but not recommended due to higher power consumption and more heat
generated inside the IRTrans. The packages used to control the IRTrans are usu-
ally not larger than 100 bytes so using 100MBit does not improve performance.
Switching to 100MBit is accomplished by setting a jumper inside the device. The
jumper must short pins 4 and 5 of the 6 pin header.
Communication between the IRTrans and the server usually happens on
TCP/UDP port 21000. This port is registered for IRTrans and may have
to be opened in firewalls.
When there is an active link the green LED on the Ethernet connector will light
up. The yellow LED flashes when data is transmitted.
By default the IRTrans uses DHCP to acquire an IP Adress. If there is no DHCP
Server available the device automatically falls back to 192.168.0.32.

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!

4.3 Devices with 2X option
IRTrans modules with 2X option offer a second independent output for external
transmitters. The IRTrans PoE is equipped with a second 3,5mm jack for this
purpose. The IRTrans Ethernet uses a stereo plug for the second output.
5. Connecting external IR receivers
External receivers can be connected by a 3,5mm jack next to the built in IR recei-
ver.
When using an external receiver it must be enabled in the device settings and the
correct receiver type has to be selected.
Older IRTrans Ethernet modules (up to hardware revision 2.2) cannot select the
receiver by software. When using an external receiver with this devices a jumper
has to be set inside the IRTrans. This jumper is located behind the built in recei-
ver and will disable the internal receiver thus enabling the external input. This is
not necessary with current revision or PoE devices.
When using external receivers firstly the receiver must be enabled and
secondly the correct receiver type has to be selected with the IRTrans
software.
6. RS232 interface
Instead of connecting an external IR receiver the connector may be used as a
serial communication port. To use this a special active RS232 cable is required
and the connection can only be uni directional.
