So, anyone know anything about these? Web info seems *very* sparse. I
found one new. It appears to me to be a generic programmable serial
control panel for large machines. It's got RS-232, RS-422, and RS-485
input and outputs. It's got a four line display and a keypad. It powers
up and appears to work fine.

The web info I found shows a program called "GUS" for programming it, and
I'm gonna download it. But I guess I'm wondering if it can be custom
programmed, or if it only supports some goofy protocols. Anyone used one?

I also can't find any decent documention on programming, so any pointers
would be welcome. I'd be interested in using it for an interface to custom
microcontroller projects perhaps using a PIC or something. Yes, I know
this isn't really metalworking related, but I believe this device *is* used
in large metalworking machinery. I gladly welcome corrections on that,
though, as I'm not completely sure.


Its intended purpose is as an interface to a PLC (programmable logic
controller) and it does communicate via some sort of ASCII protocol. I'm
not familiar with this unit, but have used several made by Maple
Systems. Maple's stuff is quite flexible and can be configured to talk
to devices other than PLCs - motion controllers, VFDs, etc. This Maple
doc may give you some clues about your device...

Some of the keywords I'd use to Google for more info would be, in
various combinations: OIT HMI PLC

Are you sure you can download the software? It's unusual to get
programming software for industrial controls for free. There's usually
at least a nominal charge.
