Operation can be achieved with just 3 wires…
¾ +24V to pin 4
¾ GND to pin 6
¾ Bi-directional serial data line to pin 8
Pins 4 and 5, and pins 6 and 7, are linked internally. The provision of extra pins is to simplify
the manufacture of a multi-drop cable using thicker wire for the power leads. There can be a
‘power-in’ and a ‘power-out’ pin, and the hoppers daisy-chained..
Note: The hopper can only operate at 9600 baud.
