I'm trying to find a way to receive a string in my compactlogix that's coming from a device typically used in a lab connected to a PC. There is 2 options according to the manufacturer. They can output it through the USB port, but this device isn't windows based and a driver cannot be added to recognize a USB to serial adapter. Also it does not act as a HID device so that eliminates being able to use a RTA USB gateway. Basically whatever gateway I use has to be able to recognize this device as a com port via the USB. I'd rather not add a PC to the system and find a simpler more cost effective way.
The other option is it has a old style 25 pin centronics style port that is meant to output directly to a printer. They said they can output the string I need that way. I found some black box brand printer to serial converters that would work, but they are powered by the serial port through pins 4 7&9 according to them and from the best I can tell the serial ports on the ASCII cards only have connections for 2&3.
At this point I'm out of ideas. Anyone have any suggestions?
