ACE3600 RTU-to-MOSCAD RTU Connection Using MDLC Protocol
through RS485
To establish a link between an ACE3600 unit and a MOSCAD RTU using MDLC protocol, the
ports of both RTUs should be defined as RS485 RTU multidrop. The ports of the two RTUs
should be connected using the 3089004V58 cable.
Do not connect between RTUs without the adaptor cables. A direct connection will
cause a short circuit between the pins that have the same function.
