Termination at PC Board
To reduce the risk of interference, the communication BUS should be terminated at each end, i.e. in the units
that are located at the start and at the end of the BUS respectively. On delivery, all buses are pre-connected
with a 120 Ohm resistor between terminals HI and LO on BUS2. When making further connections, remove the
resistor. As an alternative to resistance, the termination switch on the board can be set to the "ON" position.
