DMX to PWM Controller Driver
SR 1.xx
CONNECTION
The DPM8 PCB is a DMX to 8 channel PWM (Pulse Width Modulation) controller driver with a wide range of
tunable frequencies that can be user set. This PCB will allow up to 4 different frequencies to be tuned (2
independent outputs per frequency). The low speed frequency range is from 123hz - 31.25Khz and the high
speed frequency range is from 980hz - 250Khz. There are 8 independent outputs that will vary the duty cycle in
respect to the assigned DMX channel level. Optionally there are 4 pairs (A, B, C, D) of frequency settings that
can be user set. PWM outputs 1 & 2 (pair A), can be set to any frequency within the set low/high range, PWM
outputs 3 & 4 (pair B) and another frequency, etc. Note: The low/high frequency range setting is set for all 4
pairs and the unit will only operate in either low or high ranges. Once powered with a frequency range set all
programmed frequencies will be in either the low or high ranges.
Each PWM output is a ground drive output that allows multiple control voltages to be used. Each PWM output
can drive up to 150mA at 12VDC (30VDC Max). Designed to control SSR (Solid State Relays) that could then
directly power high power LED engines or fixtures, or any PWM circuits that uses a PWM control input (pending
ground drive capability).

- Page 1 Pin 9 - FUSED 12V OUT The DPM8 PCB is a DMX to 8 channel PWM (Pulse Width Modulation) controller driver with a wide range of tunable frequencies that can be user set. This PCB will allow up to 4 different frequencies to be tuned (2 independent outputs per frequency).
- Page 2 FOR POSITIVE CONTROL VOLTAGE PWM OUTS Connect the PWM Outs as shown for positive control voltage units. The PWM outs will output a positive voltage low current signal to control other equipment. Reference the equipment to the ground connection of the DPM8. Insure that the maximum current is not exceeded per output.
- Page 3 See the Stand Alone programming setup instructions DIP SWITCH 12 – ENTER PROGRAM SETUP MODES: OFF = normal operation. If the DPM8 is powered and DIP 12 is turned on the stand alone values can be programmed (see the stand alone programming setup instructions).
- Page 4 FREQUENCY SETTINGS The DPM8 has 4 groups (A, B, C, D) that can each have a set frequency within the Low or High frequency range selected by the FREQUENCY RANGE dip switch. 1A and 2A will have the same frequency, 3B and 4B the same etc.
