Switching unit


The unit is used for monitoring of data signals. Up to 12 balanced input signals are adapted, amplified and are feed for monitoring to one monitoring output. The active path can be selected with pushbuttons on the front panel.


The unit is housed in a 19” subrack and consist of the following modules.

-    up to 12 data switch-/amplifier modules
-    processor board with RS-232 interface
-    manual control
-    power supply unit

A subrack with very good RF shielding is used. This provides high immunity against electromagnetic interference. The optimated air flow in the subrack allows effective deheating.
All the necessary signal, power supply and earthing connections are provided at the back.
The mains switch and the pushbuttons for manual control are located on the front panel.


The crossbar is controlled via a RS-232 interface, located on the rear side of the enclosure and via a manual control module, consisting of 12 pushbuttons and 3 LED for each channel, integrated on the front of the subrack.
