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
