2.4  Communication Interfaces 

2.4.1  LTR-1200 Communication Concept 

The LTR-1200 is equipped with several communication interfaces, which can be used simultaneously. 
Every communication interface has its own receiving buffer. 
The router will process every received message. The message is forwarded to the desired device. As 
soon as the router task has received the responding message from the device, the message is forwarded 
to the corresponding interface. 
Every communication interface has the same priority. All messages are processed successively. 
 

 
A connection is always between one control software and one device. The Terminal, device number and 
Channel are not directly associated. 
Terminal represents only the output on the Back-Plane of the LTR-1200. One device can be connected to 
more than one Terminal. 
Channel represents the output channel of one device (

e.g.

 CH1 or CH2 in the case of TEC controllers.) 

Please consult the “LTR-1200 Configuration Sheet” (which was supplied with the LTR-1200) to find out 
which device channel is connected to which Terminal. 
 

2.4.2  Connecting LTR-1200 over Ethernet 

The LTR-1200 does not support DHCP. A fixed IP Address configuration must be set over the display 
menu. Please set the following settings: 

  IP Address 

  Gateway Address (required for routing) 

  Network Mask 

Please try to access to the built-in LTR-1200 web server by entering the previously configured IP Address 
to your web browser.
