Hi,
Well I added a CR into the response of the barcode scanner and still nothing
I tried using the print and input commands also and nothing.
Just for some backround, the way this scanner communicates is a command is issued and a response in sent. An example is as follows:
PLC --> Scanner: <STX>2?SF<ETX>
Scanner --> PLC: <STX>2SF000<CR>
The above is the ideal. As of now though I get no response to the message.
I hooked up the programming cable to plc comm 1 to pc comm 1. I then ran a sniffer on pc comm 1 and reset the plc. what came out was a well formed "<STX>2?SF<ETX>". I then connected the same cable to the scanner and issued the command "<STX>2?SF<ETX>". I got a response of "<STX>2SF000<CR>". Because of this I know Im running 38400,8,N,1 on both plc and scanner. The only thing I can figure at this point is flow control. Just so you know, I am connected pin 2-3, 3-2, and 5-5.
I sure hope you can figure this out. After 2 days I dont have much hair left to pull out.
Cheers,
Todd
