Synscan controller won't work
Posted 30 March 2013 - 12:52 AM
Now when I use the hand controller it freezes or simply powers off. I can barely get beyond entering the date and it freezes. I have to disconnect the cable and reinsert it for the process to start again and usually terminate at the previous step. I sent the hand controller back to Orion and they said it was fine. I upgraded the software but same results. I then sent the cable back and they say the cable is fine too. The mount and the cable connection are fine as I use a serial cable to connect the mount to my laptop to control it through EQMOD and it works fine.
Any suggestions as to what to do would be greatly appreciated.

They like nearer 14V than 12V, 2A min.
I trust the serial cable goes to the handset or an eqdir unit, not direct to the mount? that's a quick way to fry the motor control board then the handset won't connect.
Try just the handset to mount and nothing else.
Then once it's aligned you can use 'pc direct' mode to allow pc control.
(latest handsets may not need this).
I use the Celestron driver with ascom and HNSky to control the mount with a usb>serial adapter and the skywatcher serial cable to the handset which provides the TTL conversion so the voltage matches the control board, but sometimes it doesn't like having 2 masters and it gets confused.

Straight from the pc the serial control signal voltage is too high. It needs converting to TTL somehow, either through an eqdir or through the handset, or you will fry the mount's motor control board.
PC > eqdir or handset > mount.
In my case, when using a laptop with no native serial port it's;
PC usb> usb/serial adapter > handset > mount.
Try your handset on another mount and see if that works, if it does then your mount board may be suspect.

It may be something as simple as a bent connector pin, have you tried swapping out the handset cable?

In the field I plug in to a 35 Ahr deep cycle battery from a disabled buggy that gives 13.6V when fully charged and warm.
Many of the little 'wallwart' adapters don't give enough amps, typically only 500mA.
It's well worth checking the little gold contacts in the cable sockets.

Instead, I got a wireless X-Box gamepad and configured it for EQASCOM and will be using it with my laptop for mount control.
