4.5.4 MECHATROLINK Connections
The following example shows I/O350 Units connected to an MP940 Module.
When connecting an MP940 Module to an IO350 Unit, or an IO350 Unit to an IO350 Unit,
use a JEPMC-W6000-A3 Standard Cable.
Always insert a JEPMC-W6020 USB Terminator into the connector terminals (1. and 2. in the above
diagram). Refer to the section on cables for appearance and internal connection diagrams.
The connectors for MECHATROLINK 1 and MECHATROLINK 2 are the same.
Insert a JEPMC-W6020 USB Terminator into unused ports.
Only a single MECHATROLINK port channel can be used on the MP940 Module. There are two con-
nector ports, but as the above diagram shows, they are both the same.
