USB - Flexible GPIO
USB-8GPIO-FLEX
This device has the flexibility to take any combination of inputs and outputs through the 8 flex terminal connectors. Micro switches set the status of the GPIO terminal block.
A custom syntax for setting the GPIO outputs and converting the INPUTS to useable string.
All communications are via serial over USB.
SPECIFICATION
Serial over USB:
38,400 baud, N,8,1Syntax:
INPUTS state changes will send a string via the USB connector to the BrightSign device in the following format:
IN0001
First 2 letters: denote IN or OU
First 2 numbers: denote the GPIO terminal (00 through 07)
Second 2 numbers: denote the status ON or OFF (00 = OFF, 01 = ON)
OUTPUTS can be switched on and off by the BrightSign device by sending the control strings TO the board via USB. The string must be formatted the following way:
OU0301
First 2 letters: denote IN or OU
First 2 numbers: denote the GPIO terminal (00 through 07)
Second 2 numbers: denote the status ON or OFF (00 = OFF, 01 = ON)These are sent as ASCII and must contain \r\n (<CR>) to close the string. The same will be sent from the board to the BrightSign.
