Hey guys I think my 1784-pcmk card went bad. I was wanting to confirm, and ask what are my options for communicating without using RS232 port on 1747-L541. Is there a cable to go from Prog. Term. to usb or serial? To try and confirm bad 1784-pcmk card, my card was working yesterday, but today gave me an error when configuring on rs linx. It says the plug and play driver does not appear to be loaded. I see the driver in Pnp Drivers folder. In Device Manager it shows up as Generic PCMCIA memory card when I reinsert into slot. It is recognizing something is there. 1784-PCD is working in card reader also. Anything else I can try and any way to connect to Prog. Term. without 1784-pcmk?
