Greetings to all and hope somebody might be able to help solve an issue I am experiencing. At times I have been taking advantage of the tethering process: D700, the Sofortbild software an a USB cable. I turn the camera on and I'm good to go. Last week I had to send the D700 in for repairs and pulled out my backup D300. I do the exact same routine as I did with the D700 but it's not working. When the D300 is powered up I get the "PC" in the control panel and no connection to the software. I've tried bring up the software first & turning on the camera and turning on the camera first and then opening the software - same "PC" both times. There has to be a simple answer. Hopefully it is just a simple setting I've overlooked? It would be great to be up and running with the backup before my next event. No ETA yet for the D700. Thanks in advance.
