RS232 16 Input

16 input RS232 (Serial Interface Board)

Features:

The TX/RX pins can be reversed with simple on board jumper (normal or reverse TX/RX pins).  This feature supports either style of RS232 cable (null modem cable or standard RS232 cable).  The standard RS232 cable has pins 2 and 3 swapped (pin2 of one end connects to pin 3 of the other end).

Operation: (Firmware 3.2)   When an input is grounded (set low), a string is sent out that represents the input (BrightAuthor compatible).  If multiple inputs are activated, successive inputs are reported.  I.E.
