Operating Modes
NOTE:
Only one Operating Mode can be used at a time. For example, if three Input Modules were
connected together,
all three
modules would have to use the
same
Operating Mode.
Discrete Fixed (Mode Ø)
Description:
When an input (IØ - I7) is high, the associated sign message is displayed. It is possible to have several messages
running simultaneously on a sign.
Module configuration:
(modules can be connected
in any order)
Maximum no. of messages:
32
Maximum no. of inputs:
32 (8 inputs per module x 4 Input Modules connected)

NOTE:
All Input Modules are internally fused. Also, the Power Module is internally fused.
NOTE:
Wire the modules according to local electrical code.
