I recently did some tweeking to the position of my actuator arm to allow me to access more of the eastern end of the arc and sat down today to import the data and add the satellite names and send them back to the asc-1. I have already downloaded the updated loader software and updated the firmware when i initially set the asc-1 up and had done this process once before. Now when i try to send the information back to the asc-1 the asc-1 locks up when trying to send the information. I have read and re-read the manual and am making sure that i switch the master power off after downloading the list to my laptop and do a 5 count before switching it back on. after i make whatever changes i and save the file have tried several combinations of closing the editor and reopening the program and selecting my list from a saved file and sending, or re downloading the list from the device, switching the master power off, making changes, saving to file and just clicking send to device. It locks up no matter what. could this be an issue with the usb cable, my laptop having an issue? other then that the asc-1 works as it should moving to whatever saved position i select with the receiver. Thanks in advance for any help.
