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
