use with HD600 and HD2000

ROKU_GP_485    

(Roku_GPIO_DMX)

Features:

• small footprint (4.0 x 4.0 inches)
• 4 High Current Drivers (6 amp mosfets)
• Terminal blocks for all I/O connections
• Modes of operation selectable on board
• 6V,12V or 24V operation (requires external power supply)
• on board LEDs to indicate Roku Power and Processor running.
• High speed microprocessor and RS485 port for DMX-512 connection.

The modes of operations are as follows:

Operation:

This board has 12 input connections and utilizes 2 of the Brightsign Outputs for DMX control. (This can be customized).  One of six outputs and and 1 DMX control pin can be assigned.

The default configuration is setup so that LED5 and LED6 outputs of the Brightsign control the DMX operation.  Setting LED 5 high turns the dimmer pack on instantaly.  With LED 5 low, LED 6 output from the brightsign enables fade on and fade on to the DMX dimmer pack.  When LED 6 goes high, the dimmer pack fades to on (fade time selectable by teh options header).  Likewise, When LED6 goes Low, the signals are sent to the dimmer pack to fade the lights off.  Again, the fade rate is selectable by the options header.

Note: Custom software available to meet your special lighting requirement.  Any number of DMX channels can be programmed per your requirement.

See the document on DMX-512 for a description of DMX dimmer pack use and implementation.
