Expander Connection

The MCS-3000X Expanders may be physically attached to the
MCS-3400 or MCS-3800 Controller, forming a continuous
control surface.
(MCS-3800 shown with 3 MCS-3000X Expanders attached)
Alternately, the Expander can stand apart from the MCS
Controller. In that case, an optional set of simulated stone end-
bells may be purchased to make the Expander more attractive.
(MCS-3000X shown with Optional End Bells attached.)
The instructions for physical interconnection, and electrical
hookup are on the following pages.
