3.2.3 CPU and Main I/O

Standard ViewSmart 1600+ power requirements are 10-30VDC @ 12 watts applied to terminals 1 & 3(+)
and 5 & 7(-) of TB4 on the standard I/O Board. Recommended cable size is 16AWG.
TB4 terminals 2, 4, 6 & 8 of the standard I/O Board provide a maximum of 500mA fused output power for
powering of auxiliary external devices such as relays, lamps or transmitters. Power consumed from these
terminals should be considered when calculating system power consumption. The CPU board is powered
via a ribbon cable connected to the Main I/O.
