CBX ELECTRICAL CONNECTIONS 
 
4  CBX ELECTRICAL CONNECTIONS 
 
 
All  Matrix  300N  models  can  be  connected  to  a  CBX  connection  box  through  one  of  the 
available CAB-DSxx-S accessory cables. These accessory cables terminate in an M12 17-
pin connector on the Matrix 300N 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-isolated 
outputs (Outputs 1 and 2), 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 
 
The  table  below  gives  the  pinout  of  the  CBX100/500  terminal  block  connectors.  Use  this 
pinout when the Matrix 300N reader is connected by means of the CBX100/500:
