1. Connect TriggerBox to the computer.
2. Ensure the box switch is set to blue mode.
3. Ensure OS has identified TriggerBox as USB Serial Port (Windows)/ FT232R USB UART (Mac).
4. Drivers should install automatically. If not, the latest COM port drivers can be found at:  www.ftdichip.com/Drivers/VCP.htm?

Any TriggerBox running firmware 1.2 will communicate at 115200baud, 1 stop bit, no parity bit. Instructions to the TriggerBox must be printed using standard ASCII encoding. Any instruction sent to the box must end with a \n (newline) character.  The TriggerBox acts as a basic COM port, which must be opened before and closed after every session. The specifics of opening and closing COM ports are platform/software dependant, refer to your software/library user guide.

The first character of an instruction specifies either an action to be performed immediately, e.g. "S" to fire the shutters, or defines a programmable parameter, e.g. "s000111" to enable only the last three shutter outputs. TriggerBox settings can be saved to the internal memory (EEPROM) through the "O" command. Upon power-up the box will recall saved settings, negating the need to program again.

Any timing value sent to the TriggerBox is in milliseconds, and has a valid range of 0 to 30,000 milliseconds.
