THOMSON LDK 4502 User Manual page 17

When the Iso, On-Air or Call signal is
provided by a dry contact, connect the
outputs to the signalling connector as
shown in this figure.
When the Iso, On-Air or Call signal
is provided by a dry contact with a
common return connector connect
the outputs to the signalling
connector as shown in this figure.
When the Iso, On-Air or Call signal
is provided by a DC output voltage
connect the outputs to the signalling
connector as shown in this figure.
Notes: The Iso, On-Air and Call
signal is off if the input voltage is
5..24 VDC. The Iso, On-Air and Call
signal is on if the input voltage is
0VDC. The X370 Signalling inputs
are not galvanically separated. We
recommend using dry contacts and
when these are not available using
galvanically separated DC voltage
outputs.
