Operating Modes

• Short press the M key to switch between DMX decoder mode and RGB controller mode.
• Press the < or > key to adjust the parameter’s value.
• Long press MODE and > for 2 seconds to start the quick self-test feature.
• Long press the < and > key for 2 seconds to restore the unit to factory defaults.

Operation Settings

• Long press M and < key at the same time for 2 seconds. Short press M key to switch between settings:
  • Decode Mode
    • Short press < or > key to switch between 1/2/4 channel decode mode (d-1, d-2, or d-4). When set as 1 channel mode, the decoder will only occupy a single DMX address and dim all the outputs at the same level. The same is true for 2 channel mode where channels 1/3 and 2/4 will dim together.
  • Grey Level
    • Short press < or > key to switch between 8bit (b08) or 16 bit (b16).
  • Output PWM frequency
    • Short press < or > key to switch between 250Hz (F02), 500Hz (F05), 1000Hz (F10), 2000Hz (F20), 4000Hz (F40), 8000Hz (F80), or 16000Hz (F16).
    • The higher the PWM frequency, the lower the output current however it’s useful to eliminate power noise and reduce visible flickering.
  • Output brightness curve
    • Short press < or > key to switch between Linear Curve (C-L) or logarithmic curve (C-E)
  • Default output level
    • Short press < or > key to change the default 0-100% level (d00 to dFF) when no DMX signal input is detected.
  • Automatic blank screen
    • Short press < or > to enable (bon) or disable (bof) the automatic blank screen.
• To exit the menu, long press the M key for 2 seconds or wait 10 seconds with no button presses.

Stand-alone Mode

• Short press the M key. Once the display shows L01 through L5, it is now in self-test mode. This will only occur when there is no DMX signal present.
• Press the < or > key to switch through diagnostic modes.

Troubleshooting

• A DMX signal amp is typically required if more than 10-15 decoders are connected. This is especially true if the distance between the decoders is very long (250 ft+).
• If there appears to be signal loss, you can try connecting a 0.25 watt 90-120 Ohm terminal resistor at the end of the DMX signal line.
• If the display reads OLA, that indicates an overload alarm (wattage to high).
• If the display reads OHA, that indicates an overheating alarm.
• Alarms should clear automatically if the problem is resolved (may take up to 30 seconds).
