Wire jumpers (bridges) within relay connectors
●
The interface connectors for
BN512690
C0002 must provide bridges between pins
6 & 20
and
12 & 14
and
13 & 17
on the relay side (also bridging pins
8 & 9
at the
R&S
OSP-B104). The relay control cable with part no. 5354.8591.00 provides
these bridges.
●
The interface connectors for
BN640082
or
BN512698
must provide bridges
between pins
8 & 9
on the R&S
OSP-B104 side and between pins
1, 2 & 19
and
21 & 24
on the relay side. The relay control cable with part no. 3642.6776.00 pro-
vides these bridges.
These relay control cables are available via the Rohde

Interlock Monitoring with R&S
OSP-B104
Interlock monitoring with the module R&S
OSP-B104 serves two purposes:
●
Detect an open interlock circuit and inform a connected application software
●
Relay this information to power amplifiers for deactivating their RF output
Connect pins 7 and 15 of the [IN / OUT] connector your door switch, as indicated in
. Pins 3 and 4 of each [RELAY] port are connected to the external relay's
carrier safety contacts. While a relay is turning, the connection between these two pins
is interrupted, thus, opening the interlock loop.
If any of the four [RELAY] ports is not connected to an external relay, supply a bridge
(in a dummy connector) between pin 3 and 4. Not doing so prevents functional opera-
tion of the interlock.
