Termination and Biasing***
|
Set DIP switch (inside
case) if Dimmer is at the physical end of the link. Biasing must be supplied
by master for the RS-485 link.

*For rated
power, mount to a flat, thermally conductive surface (steel, aluminum).
**Do not use address 0; it is the broadcast address.
***Both ends of the physical link must be terminated. Master must supply
bias.
