CHAPTER 4
CBX ELECTRICAL CONNECTIONS
All Matrix 320 models can be connected  to a CBX connection box through one of the
available  CAB-DSxx-S  accessory  cables.  These  accessory  cables  terminate  in  a  17-pin
connector on the Matrix 320 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, opto-iso-
lated output signals, and filtered reference signals.
NOTE
If you require direct wiring to the reader the connections are the same
as shown in this chapter with the exception of the digital Outputs. Direct
wiring details are indicated in 
Appendix A.
NOTE
To avoid electromagnetic interference when the reader is connected to a
CBX connection box, verify the jumper positions in the CBX as indicated
in its Installation Manual.
