USB-4RGB

for some BrightSign units w/USB

USB-4RGB    

Features:

• 4 Sets of RGB drives (12 outputs)
•  footprint (3.5 x 3.5 inches)
• Terminal Block for 5 I/O's (programmable)
• On board LED's to indicate processor running.
• Branch Circuit Protection (Fuses) 4amps *1

Note: Branch circuit protection is set to 4 amps to match up with 24V LED fixtures in order to meet safety requirements.  For 12V LED fixtures, 6 amps versions can be ordered (Custom)

USB Setup: In BrightAuthor, select Presentation Properties, Serial Setup and select port2.  Set the port to 38,400, Ascii mode.  The USB-Serial Interface is handled by a Prolific USB-Serial converter and appears as a serial port in BrightAuthor.

I/O's (TB1):

TB1 is programmable for 5 inputs or 5 Logic Level outputs:

• Mode = 0 : The 5 I/O's are programmed as outputs.  The Brightsign Controls the Outputs with CMD xx.
• Mode = 1: The 5 I/O's are programmed as inputs and are reported to the BrightSign with input changes
• Mode = 2: The 5 I/O's are programmed as inputs and are used to select scenes to play.  Inputs need to be constant during play or play will halt.
• Mode = 3: The 5 I/O' are programmed as inputs and are used to select scenes to play. Inputs are triggers and do not require no change of state.
• Link: Binary to decimal info: 

TB1 Mode = 1:

• Close the inputs to 0V (buttons/switches) to activate the inputs.  The inputs are reported as strings to the BrightSign and are evaluated as decimal in BrightAuthor.  I.E. Sending "1",13 causes a serial string event and evaluates as 1 (not "1").
• When an input is released (goes back high by internal pull-up resistor) an 8 is added to the string.  I.E. "81",13 indicates input 1 was released.  This scheme allows the programmer to respond to inputs going high if needed.
