The common port ("Com") of this high performance relay switch module can be
switched to one of two input/output ports ("In A", "In B"). The unused input/output
port is terminated internally.

The port "In A" of the high performance relay switch module is connected either to
the port "Out A" or to the port "Out B". In the latter case, the port "In B" is connected
to the port "Out A", otherwise to the port "Out B".
Note that logically, this transfer switch module is handled like any other 2:1 (DPST)
switch, i.e. the representation in the Web Interface, via SNMP, and via all CPH
protocols corresponds to a 2:1 switch even though the signal routing is realized as
described above.

The common port ("Out") can be switched to one of two input/output ports ("In A",
"In B"). The unused input/output port is terminated internally. The module is able to
pass an external 10 MHz reference signal.
