USB / RS 485

It is possible to 'daisy-chain' multiple units together so they are controlled via USB on a Mac or PC.

The first unit on the chain should be connected to the Mac or PC by a USB cable (not supplied).

The blue USB/RS485 button on the rear of this unit should be pushed in.

Subsequent units are connected from the RS 485 OUT of the 1st unit, to the IN on the 2nd; from the OUT of the 2nd to the IN of the 3rd and so on
