Setting The Extension Number Of The Extension Base Unit - Mitsubishi Electric MELSEC-Q Series User Manual

4.1.5 Setting the extension number of the extension base
unit
When using two or more extension base units, their extension numbers
must be set with their extension number setting connectors. Extension 1
need not be set since the extension number is factory-set to 1.
Make this setting in the following procedure.
(1) The extension number setting connector of the extension base unit
is located under the IN side base cover.
First, loosen the upper and lower screws in the IN side base cover
and remove the base cover from the extension base unit.
(2) Insert the connector pin in the required extension number location
of the connector (PIN1) existing between the IN and OUT sides of
the extension cable connector.
