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.
NOTE: The MNS-Cntrl has been pre-set at the factory.
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:
Maximum no. of messages: 32
Maximum no. of inputs: 32 (8 inputs per module x 4 Input Modules connected)
