Information

The 1260 switching modules are a range of C size, VXlbus compatible switching modules that provide switching for microwave, RF, audio, high voltage, high current, low level and video applications. The modules are configured as matrices, multiplexers, switching trees, SPDTs and DPDTs. The switching modules are installed in a VXlbus compatible chassis in a continuous set of adjacent chassis slots. One of the modules to be fitted to the chassis must be designated the system Master, and must be fitted with Option 01. All other modules are slaved to the master. The module fitted with Option 01 must be fitted in the leftmost chassis slot that is to contain a switching module. If only one module is to be fitted to the chassis, several jumper wires must be removed from, or DIP switches opened on, the switching module. !f more than one module is to be fitted to the chassis, these jumpers must be removed from (or the DIP switches opened) the module in the rightmost chassis position containing a switching module.
