Pathway Connectivity PWINF DMX Interface, 6-Channel PWM DC Dimmer

About: Pathway Connectivity PWINF DMX Interface, 6-Channel PWM DC Dimmer

Pathway DMX Interfaces provide a flexible way of creating custom solutions to DMX control challenges.

The 6-Channel PWM DC Dimmer provides direct pulse-width modulation (PWM) control of common anode, constant voltage LED fixtures and other DC loads.

Multiple modes, including 16-bit resolutions, ensure a smooth dimming curve. The unit provides efficient switching control of DC devices such as solid-state relays and solenoids.

Compact and DIN-rail mountable, the Pathway 6-Channel PWM DC Dimmer is field configurable through its front panel, or through RDM.

Features

• Convert DMX512 levels to PWM (Pulse-Width Modulation) signal
• Control constant voltage LED fixtures rated between 5 to 30VDC1
• Six PWM outputs, individually fused at either 4A or 6A; spare fuses included
• Inputs for six auxiliary source 0-10VDC control signals are HTP-merged with DMX input
• DMX-present relay for external triggering of relays or control signals (normally-open or normally-closed)
• Contact Closure "panic" input drives all outputs to full
• DMX512 start address and operating mode configurable from front panel or remotely using RDM
• Indicator LEDs for Power, Processor, DMX Input, Active Output
• User-configurable smoothing algorithm
• User-configurable minimum and maximum output levels
• Multiple loss-of-signal options
• Diagnostics and test modes
• DMX line termination switch
• Data and power easily daisy-chained to other DIN Interface units
• One DMX Input, and one DMX Thru connection 

Operating Modes

Mode 1: Default LED Control (6 Channel)

Incoming DMX slot value is interpolated to create an internal 16-bit value. A weighted fade curve is applied to the output to compensate for LED response, producing an apparently linear fade to the human eye.

Mode 2: DMX Double Precision Mode with Curve (12 Channel)

Two DMX control slots from the controller (coarse/fine) are used to produce a 16-bit value for each output. A weighted fade curve is applied to the output to produce an apparently linear fade to the human eye.

Mode 3: DMX Double Precision Mode without Curve (12 Channel)

Two DMX control slots are used to produce a 16-bit value for each output. No compensating curve is applied. Output follows the DMX values linearly.

Mode 4: Non-Dim Mode

When the value of the corresponding DMX slot is below 50%, the associated output will be off. When the DMX slot is above 50%, the associated output will be on (full). A hysteresis zone of about 1% occurs at the 50% level, where the output's state is undetermined. Use this mode to drive non-dim loads such as solid-state relays and solenoid coils.

Mode 5: Single Channel Control (1 Channel)

One DMX slot (the start address) controls all six outputs simultaneously. A weighted fade curve is applied to the output to produce an apparently linear fade to the human eye.

Mode 6: Three Channel Mirror with Curve (3 Channel)

Outputs are paired (1 and 4, 2 and 5, 3 and 6). Paired outputs are driven by the same DMX control slot. The DMX value is interpolated to create a 16-bit value. A weighted fade curve is applied to the output to produce an apparently linear fade to the human eye.

Mode 7: Three Channel Mirror without Curve (3 Channel)

Outputs are paired (1 and 4, 2 and 5, 3 and 6). Paired outputs are driven by the same DMX control slot. The DMX value is interpolated to create a 16-bit value. No compensating curve is applied. Output follows the DMX value linearly.

Util Mode Options

• A: Adjusts the smoothing algorithm between 1 (very smooth) and 100 (no smoothing). Default is 64.
• B: Adjusts a Grand Master maximum output level between 0 (off) and 256 (full—default).
• C: Sets a minimum output level between 0 (default) and 255, that the card will always maintain, even in the absence of DMX.
• D: Sets loss-of-DMX behavior. Options, as shown on the seven-segment LCD screen, are “0” - zero seconds; “0.5” - thirty seconds; “1” - one minute; and “--” - forever (default).
