Well I just tried to update the handset and it failed again. This is starting to bug me!
When I insert the Jaycar USB-RS232 cable into the PC my Device Manager lists the new port as "Prolific USB-to-Serial Comm Port (COM7)"
Then, after the ETX-90 has been powered up, I connect the Meade cable into the Audiostar. Next I start StarPatch, and set the port to COM7 via Options, and select the Audiostar handset.
Then I selected the spf via the pull-down list, and unticked the 4 or 5 items at top to do with GPS, leaving all the rest as they are.
All good so far. But when I hit the Update Handset button nothing happens for a short while, then StarPatch issues a comms failure message appears
(see attached).
I repeated all the above usiong COM5 instead, and even a PC reboot. same result. Grrrrr ...
Perhaps I need a different driver, or I've damaged the connection cable somehow? It did work a couple of weeks ago when I was playing with Autostar Updater, but even that doesn't work now.
BTW when the Audiostar is powered on it displays:
497EP A3S5
AUDIOSTAR
