Set the Expander ID#
On the rear of the Expander is a small cluster of four switches,
known as DIP switches.
When the rear dip switch number 4 is up, that is, off, the 3
remaining switches are used to set the “ID” number of the
3000X Expander.
These switches set the ID# of each Expander, so the system
knows which Expander represents channels 1 through 8,
which is 9 through 16, etc.
Set the left-most Expander for ID#1 by making sure that
all four switches are up, that is, off.
Follow this chart to set the ID# of multiple units. Off = Up

Important: Be Sure Each Expander has a Unique ID#
A multiple expander system will not operate correctly if two or
more units are set to the same ID#.
On power-up, turn the Expanders on before the MCS-3800.
The MCS-3800 LCD will display the number of 3000X units
connected.
