Jim,??
Attachments are not allowed so we are not seeing what I assume are your screen captures.
I read thru the previous thread and what was suggested. ? Are we dealing with Windows or MAC? this time.
306? is a " not talking to Command Station ".? This could be the PR3 not talking to your DCS51 Zephyr Command Station while the PR3 is in
the Interface mode or it could be the PR3 is in Standalone Programmer mode but the setup is wrong.? This needs to be determined,
Check device Manager for the USB Serial Device. Connect / disconnect? the PR3 a few times while looking at DevMGR? to confirm which COM it has been
assigned . Is the Device Driver loaded? for it (USBSER.SYS) .
