Condition: During a file transfer, or during the Suneye software installation process, you see this message: ?Error connecting to your Solmetric SunEye device. Please connect your Solmetric SunEye ? device with the USB cable, turn its power on, and click ?Next? to connect to it? Please follow the instructions on this page: http://resources.solmetric.com/get/SunEye-WMDC-settings.pdf (see attachment below) From the SunEye downloads page ( http://www.solmetric.com/downloads-suneye.html ) Before installing the SunEye software: The Windows Mobile-2003-based device connectivity (WMDC) ‘service’ needs be running before installing the SunEye software. Follow the SunEye-WMDC Instructions to configure the WMDC. If this is a new installation, click ‘skip’ when prompted to plug the SunEye USB cable into your PC. You can then configure the WMDC after installing the SunEye software. If you see the message: “Waiting for device connection” or “Error connecting to your Solmetric SunEye Device” , the ‘Windows Mobile-2003-based device connectivity’ service is most likely stopped. Please download and follow the SunEye-to-PC Connection Instructions (see link above or attachment below) to correct the issue. If you see a RAPI.dll error when launching the SunEye program, you will need to reinstall Windows Mobile Device Center. Please see link on SunEye downloads page. The Microsoft download page will say it is for Windows Vista, but this version works on all versions of Windows. Be sure to select the correct version for your PC (probably 64 bit). General instructions to fix the WMDC: Step 1 ? Open the Services window -Search for ‘services’: type ‘serv” in the ‘type here to search’ box, click on the best match – should be ‘Services app’ Step 2 ? Edit the ‘Windows Mobile -2003- based device connectivity’ service -Scroll down the Services list and locate ?Windows Mobile -2003- based device connectivity service?. Double click to open the service editor. Navigate to the ? Log On ? tab. Change the ?Log on as? to ?Local System account?. Click apply. Navigate to the “General” tab, and ‘start’ the service. Click OK. Step 3 – Do the same for the “Windows Mobile – Based Device Connectivity” service. (You will see a message that the ‘changes will not take effect until you stop & restart the service’ – click OK) You can now close the ‘Services’ window. Step 4 – Launch the Windows Mobile Device Center app; ‘Accept Terms’, and ‘Allow this program to make changes to your device’. Step 5 – Unplug and reconnect the SunEye to your PC, wait for the ‘beeps’, and for the message in the Windows Mobile Device Center window to go from ‘not connected’, through ‘connecting’, to ‘connected’. If it does not connect, re-boot the PC. If it still doesn’t connect, please test with another cable (USB ‘mini-B’), and call Solmetric Technical Support for help.
