Configuration of the Line Termination
On the right next to the plug bridge fields for the E1 connection you will find a two-pole DIP switch with which the line termination can be configured.
*If both pins of the switch are in the "OFF" position, no termination is switched on.
*If the left pin is on the "OFF" position and the right pin is on the "ON" position, this means that this has a 120 ohm line termination.
*If the left pin is on the "ON" position and the right pin is on the "OFF" position, this means that this has a 75 ohm line termination.
