I have a dozen or so of these boards in the field, currently installed where I cannot get to them. There are fully wired for various i/o pins.
We currently only use 4 I/O which generate the RS232 data that the PC acts on. We’d like to send a RS232 command and use one of the i/o pins as a control line.
We expect to have to do our own programming, but need the original software that is shown in the manual - along with any instructions on how to use the software.
Or it may be that the board has pre-programmed functionality that cannot be changed, in which case we need the software so we can experiment with sending RS232 commands and getting of the i/o pins to trigger from the RS232 command.
Any help anyone can offer (other than any suggestions involving replacing everything, using a new piece of hardware etc. - not that these are valuable inputs, but with Covid, we have no access to the hardware/system and cannot implement a more “modern” solution).
