*1: There are restrictions to the distance between stations, being determined according to
the type of cable and number of stations. See sections 5.1, 5.2.1 and 5.2.2.
*2: Specialised training and specific tools are required to connect the connector to the
optical-fiber cable; the connector itself is a custom product. Please contact your nearest
Mitsubishi Electric System Service Corporation when purchasing these items.
For general specifications of the network module, refer to the user's manual for the PLC CPU
that is to be used.
