RTU-to-RTU Connection Using MDLC Protocol through
RS232
To establish a link between two RTUs using MDLC protocol, the ports of both RTUs should
be defined as RS232 RTU-to-RTU (RS-Link). The ports of the two RTUs should be
connected by the FLN6457 and FLN6458 adapters, when the adapters are connected.
!
IMPORTANT
Do not connect between RTUs without the adapter cables. A direct connection will
cause a short circuit between the pins that have the same function.
