When multiple ZM-
**
are connected to a link unit of PLC, use the terminal converter (ZM-1TC), the
optional equipment for RS-485 connection.
• Set the dip switch (SW1) of ZM-1TC as 2-wire connection when the ZM-1TC terminal converter is used.
• Short-circuit between +RD and +SD, and -RD and -SD when the ZM-1TC terminal converter is not
used.
When multiple ZM-
**
are connected directly to MITSUBISHI’s QCPU port, the optional equipment, ZM-
1MD2 is required. Make sure to use ZM-1MD2 GD port. It is recommended to use a cable, MB-CPUQT, to
connect between a terminal converter ZM-1TC (sold separately) for a ZM-
**
and a ZM-1MD2 for the
Mitsubishi Q series’ CPU too.
• Set the dip switch (SW1) of ZM-1TC as 2-wire connection when the ZM-1TC terminal converter is used.
• Short-circuit between +RD and +SD, and -RD and -SD when the ZM-1TC terminal converter is not
used.
