Brightsign USB-A-8IO

for some BrightSign units w/USB

USB-A-8IO    

Features:

• Small footprint (2.5 x 1.5)
• 8 Logic Outputs (USB-A-0x8) or 8 Logic Inputs (USB-A-8x0) or Custom
• Plugs directly into some BrightSigns!
• On board LED's to indicate 5V Power and processor running

This board solves the need for a simple 'low cost' expansion port for the Brightsign Video Player.  The board has a cutout to clear cables on most BrightSign units.  Please verify that it will suit your mechanical requirements of your BrightSign before ordering

USB Setup: In BrightAuthor, select Presentation Properties, Serial Setup and select port2.  Set the port to 19,200, Ascii mode.  The USB-Serial Interface is handled by a Prolific USB-Serial converter and appears as a serial port in BrightAuthor.

Operation:

8 Outputs:

• The board powers up with all outputs low (0V).  Send a single decimal byte to control all 8 outputs.  Use the 'serial sendbyte comma separated' command.
• Link: Binary to decimal info: 

8 Inputs:

• Close the inputs to 0V to activate the inputs.  The imputs 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.

Custom:

   The board can be ordered with custom inputs/outputs.  Allow a couple of extra days for custom orders.

• USB-A-7X1 = 7 INPUTS, 1 OUTPUT
• USB-A-6X2 = 6 INPUTS, 2 OUTPUTS
• USB-A-5X3 = 5 INPUTS, 3 OUTPUTS
• USB-A-4X4 = 4 INPUTS, 4 OUTPUTS
• USB-A-3X5 = 3 INPUTS, 5 OUTPUTS
• USB-A-2X6 = 2 INPUTS, 6 OUTPUTS
• USB-A-1X7 = 1 INPUTS, 7 OUTPUTS

Note: Inputs are the low inputs (1 thru ?) and outputs are the high outputs (2-?)  I.E. if USB-A-4x4 inputs are 1-4 and outputs are 5-8
