NOTE: RS-232C modular cables must pass through 
a 1.2” thick, 2-348” diameter, round ferrite core three 
times prior to exiting the KSU in order to comply with 
FCC regulations. Up to five cables can be wrapped 
around one ferrite core. 
An optional I/O module may be added to the CBP 
adding one additional RS-232C port (8 pin modular 
4 
jack type connector) and one RS-422 port (6 pin 
modular jack connector). Refer to Sec. 500.6 for the pinouts...
