NOTE:
CLICK’s RS-232 port can provide 5VDC to power one monochrome Micro-Graphic panel. If
two C-more Micro-Graphic panels are connected to both ports, then at least one of the panels must be
powered by a C-more Micro DC power adapter, EA-MG-P1 or EA-MG-SP1, or another 24VDC power
source. Color C-more Micro-Graphic panels must also be powered from a separate 24VDC source.

TIP:
C-more Micro-Graphic panels
(monochrome models only) can get 5VDC
power from RS-232 Port.
The Color Micro-Graphic panel or the
second Monochrome Micro-Graphic
panel needs a separate 24VDC power
source (see the note below).
