BrightSign Sync Board

for Brightsign Units with GPIO

Sync_board    

Features:

• small footprint (1.3 x 1.9 inches)
• 4 Output Drivers for Brightsign Players (1 ampere maximum each output)
• 4 Inputs (direct to the Brightsign)
• Attaching Hardware Included (2 custom screws)

This board solves the need for 'Custom Sync' cables.  The Brightsign has a limitation of driving about 3 other BrightSign video players on a single channel.  This board has Mosfet drivers to drive up to 100 video players.   Four inputs go to the Brightsign inputs (Btn-0 through Btn-3 and four of the Brightsign I/O pins (Btn-4 through Btn-7) drive the outputs.

Note: Do NOT connect the 3V terminal to any BrightSign!  The 3V terminal is for Testing Only!
See the schematic for constructing and LED Indicator Fixture

BrightAuthor Setup:

Under 'File, Preferences' set Btn 4 thru Btn 7 to outputs.

Set these outputs low in the attract loop or startup of the play sequence.

Programming the sync of Master and Slaves:

In order to synchronize all player, they need a 'pre-load' signal and and play signal.  The pre-load command allows for the time to search the memory card and load the file (ready to play).  After a pause, the master sets the signal 'play file' to high (true) and starts the video.  The slaves respond to the 'play file' signal and immediately start their files.
