Supplying Power:
There are several ways to supply power to the Suprex units. Each of these will be
discussed in detail.
A. The “
4 Wire
” method. This method uses one supply to power both the Central and
Remote units. It requires 4 wires to connect the two units together. A typical power supply would be
a 12Vdc “wall wart” rated at 500 ma.
The power supply can be located at either the Central or Remote unit. However, only one power
supply should be used for this configuration.

The 4 Wire method is used when there is only one power supply and the distance between the two
units is not very large.
