4 CBX ELECTRICAL CONNECTIONS
All Matrix 450™ models can be connected to a CBX connection box through one of the
available CAB-MSxx accessory cables. These accessory cables terminate in a 19-pin
connector on the Matrix 450™ side and in a 25-pin male D-sub connector on the CBX side.
We recommend making system connections through one of the CBX connection boxes since
they offer the advantages of easy connection, easy device replacement and filtered
reference signals.
If you require direct wiring to the reader the details of the connector pins
and relative connections are indicated in Chaper 5.
NOTE
The table below gives the pinout of the CBX100/500 terminal block connectors. Use this
pinout when the Matrix 450™ reader is connected by means of the CBX100/500:
