R&S OSP
there is a problem with the power on the corresponding connector. In such a case,
please turn off the OSP, try to correct for a possible fault in the cabling or the
connected device, turn the OSP back on and check the LED again.
The LED below indicates the status of the interlock (pins 7 and 15). If there is no
connection between these two pins, or if any of the RELAY connectors does not
connect its pins 3 and 4 (bridge at the connector or carrier safety status of the
connected relay), the LED will show a red light indicating an open interlock. The LED
being off indicates that the interlock is closed.
The input ports are available on the upper D-Sub connector IN / OUT. The input port
can be read at any time. Each input is protected with low-pass and diode against
transients.
The output ports are also accessible on the upper D-Sub connector IN / OUT. Each
output channel is designed as a FET driver switching to GND when activated. Each
output is protected with diode against transients which may occur when switching
inductive loads such as relay coils. All output lines can be programmed independently
from each other.
The R&S OSP-B104 module is supplied with power and controlled from the R&S OSP
via one supply and one control connector on the R&S OSP-B104 printed circuit board.
The connection to the R&S OSP is done via those two connection cables.
The R&S OSP-B104 module is equipped with an on-board memory to store the
necessary configuration data of the module.

When the module R&S OSP-B104 is configured within the R&S OSP, a manual operation
of the module can be performed via the OSP Panel. See
