The D868 programming cable is, I believe, a simple straight-through USB cable (with the special end). If there is no obvious damage to the cable, I would look elsewhere for the problem.
Here is a link to a D868-specific pdf file from Connect Systems. Refer to the Getting Started section near the bottom of the first page to confirm that your drivers are still valid - Windows updates have been known to corrupt drivers.
Good that u helped me remember that fact. AND i just spent $32 on special driver software that didn't work to help program the 868. The 868 software keeps saying can't communicate with radio and xmit comes on with red light on top.
Any help greatly appreciated !!
The CPS does not remember the com port number previously selected. It seems like the last couple of updates the CPS got 'fussy' about displaying the list of com ports you could select in SET COM. Fussy is not displaying correct number when I think it should. Usually shutting down and restarting has always got it going again.
I'm not sure what the red light is about in normal program mode. Only in Firmware or Icon update does the light come on indicating mode enabled.
With the radio off and then connecting radio and computer, when you turn the radio on does the computer make the connect/new device sound? If not then I believe something is amiss with the driver. If it does make that sound check to see if you have a different com port number to use. Typical of operation system to change number if you use a different physical USB connector on your computer.
