DMX input connection:

Apply DMX512 signals to
the connector labeled
DMXIN. Pin outs and
color codes are as follows:

LED indicators:

LED Color Ref Des. Function
Red D8 Power
Green D3 Signal
Amber D4 Output Level Mimic for Channel 1

Address settings:

The DIP switches at the end
of the board are used to set
the DMX address in binary
format. The address is set
from the sum of values.

Example: To set the start
address to 200 switch ON
switches 8, 7, 4. Switches
1,2,3,5,6,9 should be
switched OFF

connection. Output is 0 to 10 VDC @ ( ) 15 mA ( )100mA. Maximum output voltage
can be adjusted using trim pot R8.
The output will respond to the ( ) first ( ) second ( ) third addressed DMX channel.

Connect wires for the analog output to terminal block TB1 using the COM and CH2
connection. Output is 0 to 10 VDC @ ( ) 15 mA ( )100mA. Maximum output voltage
can be adjusted using trim pot R6.
The output will respond to the ( ) first ( ) second ( ) third addressed DMX channel.

The relay closure is available on header J2. The Common (Black), Normally Open
(N.O., Red), and Normally Closed (N.C., White) connections are present on this

0.156" header. The relay will close when ( ) first ( ) second ( ) third addressed DMX
channel goes above 60%. It turns off when the channel goes below 40%.
