1-5 Expanded System Configuration
1-5-1 Serial Communications
The FQM1 system can be expanded using the two serial ports built into the
Coordinator Module: Peripheral port and RS-232C port.
System Configuration
1-5-2 Systems
The serial communications port mode (protocol) can be switched in the Coor-
dinator Module’s System Setup. Depending on the protocol selected, the fol-
lowing systems can be configured.
