DIP SWITCHES – It is recommended to have a DMX Start
Channel value of 503 or less to have channels assigned to 8
PWM outputs and 2 for fre uency programming and setup. See
the Fre uency Setup Procedures for ore infor ation.
NOTE – A RESET/REPOWER IS REQUIRED FOR DMX START
CHANNEL and LOW / HIGH SPEED FREQUENCY SETTINGS
DIP SWITCHES 1-9 - DMX START CHANNEL: [POWER RESET
REQUIRED] sets the DMX512 start channel
(see the DMX512
Channel Assign ent Docu ent). PWM output 1 will be the DMX
assigned start channel and the 2
nd
PWM output is controlled by the
assigned DMX start channel +1 (consecutively) and so on.
Dip Switch’s 1-6 are also used to program the fre uency settings. See the
Frequency Setup Procedure
LED INDICATOR – The Power LED will illuminate indicating power is applied. The Status LED will indicate the
status and modes of the DPM8.
STATUS LED: ON: indicates DMX data is being received.
OFF: indicates no DMX data is being received and the unit is in Stand Alone Mode
SLOW BLINK:
DMX receive error – [overrun error] (reset clears)
Pre Program/Setup Mode, waiting on user to apply settings
MEDIUM BLINK: Programming/setup mode
RAPID BLINK: Programming/setup mode can’t be entered, check settings
PULSE: Programming/setup complete – Reset DIP Switches if needed and RESET POWER
DIP SWITCH 10 - FREQUENCY RANGE: [POWER RESET REQUIRED] sets the low or high fre uency ranges
for all outputs. OFF (down position) = low fre uency range. ON = high fre uency range.
DIP SWITCH 11 – STAND ALONE (No DMX): OFF (down position) = With no DMX signal the all PWM outputs
will turn off. ON (up position) = With no DMX signal the PWM outputs will be the user preset (8 independent)
values. See the Stand Alone progra ing 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 progra ing setup
instructions). When powering up the DPM8 and DIP 12 is ON then the fre uency settings can be programmed,
modified and stored. See the Frequency Setup Procedure instructions
STANDALONE MODE - The Stand Alone Mode is activated when there is no valid DMX present indicated by
the status indicator off. The PWM duty cycle values are all off if the Stand Alone Dip Switch is in the OFF
position. The user set PWM duty cycle values are applied when the Stand Alone Dip Switch is in the ON
position. Take care to setup the values and place the dip switch in the desired position. Test the unit to insure
the desired results.
