Current Loop Cable Wiring 

You can wire the ACM/Flex16 with the 20mA Current Loop 
option in various ways to communicate with 20mA Current Loop 
peripherals.  This section describes an example of a Current Loop 
cabling scheme. 

 

Figure 22

 describes a 4 wire cabling scheme between a port on 

the ACM/Flex16 and another port on an external device.
