Multiplex

The Programmable Multiplex Control (PMC)
consists of three basic components. The Control
Master, fuse modules and switches located
throughout the motorhome.
The Control Master continually monitors
the status of all switches and fuse modules.
When a switch is pressed, the Control Master
identifi es the address and command of the
switch, processes the command and activates or
deactivates the corresponding circuit on a fuse
module.
Operation:
Some switches operate items directly, such
as a light or the water pump. Other items are
programmed to go through a series of checks
before the switch will operate the item.
All dimmable lights have seven settings.
Dimmable lights are marked with up and
down arrows next to the light location
noted on the multiplex switch. Press
and hold the switch to cycle through
the different settings. The system will
remember the dimmed setting when
turned off.
