9.4 How to Set Stage Numbers for the Extension Base Unit
When using two or more extension base units, their stage numbers must be set with
their stage 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 stage number setting connector of the extension base unit is located under the
IN side base cover. (Refer to Section 6.4 for the setting of the extension number
setting connector.)
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 stage number location of the connector
(PIN1) existing between the IN and OUT sides of the extension cable connector.

(3) Install the base cover to the extension base unit and tighten the base cover screw.
