5.5.2 Installing an RS232/RS485 module
This component is installed in exactly the same way as for the operating units
with the PMI & mainboard FCM2004 and the PMI & mainboard FCM2027.
No more than one single interface module (RS232 or RS485) can be installed in an
FC721.
The serial modules include:
● RS232 module (isolated), FCA2001
● RS485 module (isolated), FCA2002
These modules are mounted in the slots designed for them on the operating unit.
The mounting procedure of the two serial modules is the same for all modules.
