CONTROL SIGNAL
The DMX-512 control signal enters the RE-82D through a 5 pin "XLR" connector on the rear of the unit. A second
connector is used to continue this control signal out to other dimmers in the system. Normally the male
connector is used for the incoming control signal and the female connector is used to loop out to other dimmers.
These connectors are wired in parallel so either connector may be used as input or output. The table below
shows the control signal connector pin assignments.

UP FOR RELAY MODE
Any switch in the up position ADDS the associated value to the starting channel number. All switches down =
starting channel number 1.
For example: to set the starting channel to 13, move the 2nd switch from the right (value 8) and the 1st switch
from the right (value 4) to the up position. For a starting channel of 21, move the third switch from the right (value
16) and the rightmost switch (value 4) to the up position.
MANUAL CONTROL
Dimmer channels can be activated manually by pressing corresponding button switches located on the front
panel. This will latch the associated channel to full on. Push the button again to turn the channel off. The
associated LED will light when the channel is activated.
