Switching unit


This unit combines up to 17 switch boards, a backplane and a signal input board. Each switch board acts as a matrix with 20 inputs and 5 outputs furthermore 5 crosspoints can be switched at the same time. All input signals (20 max.) which are connected to the input board are routed via the backplane to every existing switch board. Every input signal can be switched to one or more or all existing outputs of the unit.


The switching unit is housed in a 6 U 19“ subrack with very good RF shielding and consists of the following sub-assemblies:

-    switch boards with max. 20 inputs and 5 outputs
-    I/O board
-    processor board
-    IEEE488 interface
-    manual control module

All the necessary signal, power supply and earthing connections are provided at the rear.
The mains switch is located on the front panel.


The unit is controlled via an IEEE488 interface and via a manual control module with a LC display and pushbuttons which is integrated on the front panel.

Special features

The I/O boards are monitored in a processor routine.
The selected crosspoints as well as the I/O fault messages are displayed on the manual control module.
A status string can also be requested at any time via the control interface.
The unit is constructed using a modular approach utilising 19” plug-in sub-assemblies which enable ease of installation and maintenance.
