Operating instructions

4.1.3 Network Termination
Dependent on the type of topology, at least one of the connected nodes must be terminated (52.5Ω). The option has two built-in termination circuits
which are activated by the terminator switches S300 and S301.
If termination is provided elsewhere in the network, the termination switches should be OFF. If a double-terminated bus topology is used, the first and
the last node should be double-terminated (105Ω).
Termination switch positions are shown in the table below.
Termination type S 300 S 301
No termination (factory setting) OFF OFF
Double termination (105 Ω)ONOFF
Single termination (52.5 Ω) ON ON
