For any units with USB Port

8 Inputs, 8 LED DRIVES

USB-RJ12-8X8-5V (SET OF 2)

Features:

• This board set is used to 'remote' buttons or LED's or buttons with lights.
• The USB portion of the 'Set' plugs directly into a USB port.
• Footprint (2.5 x 2.5 inches) (I/O board)
• 8 Inputs (for logic interface or switches)
• 8 LED drives (direct drive to the LED or switch light)
• On board LED's to indicate Processor running.
• Serial Setup: 38,400 baud, N,8,1 (standard serial communication)
• RJ12 phone cable for easy interface (up to 50 feet) (order separately)

Outputs:

The Controller (BrightSign or other controller) has to send a single byte to control the 8 outputs.  The bits of an 8 bit byte controls the 8 outputs.

At any time, the Brightsign sends out the 'Set Port Byte', then the outputs will turn on according to the bit pattern of the 'Port Byte'.  I.E. Bit 0 of the byte set to '1', will control output 1.  Bit 7 of the byte set to '1' will turn on control output 8.

I.E. To control the outputs, send the byte that represents the bits of the lights (see table below).  The single byte turns on/off the LED's according to the bits and option 2 setting.

Option 2 (OFF)  The port byte is not inverted.  So sending a binary '1' turn on the output 1

Option 2 (ON)  The port byte is inverted. So that sending a binary '1'  turns off the output 1

• Bit     Binary              Decimal      Output                                                    
• 0       00000001b      1d                  1
• 1       00000010b      2d                  2
• 2       00000100b      4d                  3
• 3       00001000b      8d                  4
• 4       00010000b      16d                5
• 5       00100000b      32d                6
• 6       01000000b      64d                7
• 7       10000000b      128d              8

Just add the decimal numbers together to get the bits set that you want.  Setting all bits is 255d (decimal).  Setting bits 0 and 7 is 128+1 or 129 decimal

Inputs:

As inputs are closed, a string representing inputs 1 to 8 is sent (2 bytes).  I.E.  "1",13 (ascii 1 followed by a carriage return for input 1 closure.  This way the BrightSign will respond to the inputs after a carriage return.

When all inputs are released, a 'zero string' is sent.  I.E. "0",13 (ascii 0 followed by a carriage return

Options:

Option 1 does a cycle diagnostic (cycles the outputs and sends decimal 170 to the BrightSign

Option 2 'OFF' passes the port byte to the outputs.  So that bits that = 1 turns on the light

Option 2 ON inverts the port byte so that bits = 1 turns off the light

Note: It is highly recommended that you use a 'serial port terminal' with your computer to get familiar with the operation of the board
