CM4 Four-Point Continuous Monitor

CM4 Technical Manual

E-31

E.7 Serial Device Applications

The  serial  interface  is  designed  for  unidirectional  communication  from 

a CM4 monitor to a single printer or other remote device. It is possible, 

therefore, that the application for this interface requires connection to a 

remote device other than the printer options described in this appendix.

 CAUTION

Cabling used between the CM4 monitor and the external device must 

be shielded and properly grounded to maintain reliable operation and 

control RF emissions and susceptibility

For these applications, note the pin-out configuration in each of the diagrams.
