hope someone can help. I have a Celestron Astro Fi 5 telescope which naturally doesn't come with a hand controller, but I got that stressed out with WIFI and the sky portal app that i couldn't cope with the disconnections and hoped that a Celestron hand controller would be a better solution. So I pulled the trigger and bought one on Ebay without really researching a compatible one for my scope. Anyhow I have tried it on my cope and it seems to show the message Transmit Data and this message stays on the hand controller. Now i am wondering have i bought the wrong version of hand controller for my scope. On researching i can see that the version 4 hand controller is compatible with mine but it doesn't show on the hand controller which version it is. if i post a picture does anyone know which version this is?
If it is the correct version of hand controller is there any other reason the controller could be stuck on Transmitting Data?
any help much appreciated,
That's a NexStar* ("NexStar-star", Version ) HC. NexStar+ ("NexStar-plus") HCs have different button positions and nomenclature.
NexStar* HCs run Version 3 or Version 4 firmware. Version 3 HCs can not be updated by the user; Version 4 HCs can be. I think that "Transmit Data" mode is for programming, so that one is probably v4.
NexStar+ HCs run Version 5 firmware.
If you can get it to work at all, the Version command under the Utilities menu will tell you exactly what firmware is loaded.
If it always 'wakes up' in Transmit mode, some keys might be stuck. If both the INFO and UNDO buttons are pressed on power up, it wakes up in Transmit mode. Maybe try jiggling them, or starting with them pressed then restarting with them not pressed [grasping at straws here].
Pressing the 0 (Zero) button while powering up will do a factory reset (I think... it does on v5 HCs). You will probably want to do that before using it, anyway. Give that a try... maybe that will shake the cobwebs out [more grasping at straws, but can't hurt].
Mike Swanson's excellent nexstarsite.com is a great resource for all things Nexstar. Maybe he will notice your plea and ride in to your rescue here, too.
Good luck! Please let us know what you find.
