Hi PDB,

I found the exact entry you referred to :-)

It was already commented out !

Not sure whether to laugh, cry or just buy a new cable.

Actually, I've ordered a new cable :-)

Yes, there are many reports of cloned/fake so-called prolific chips.

However, do bear in mind that in this instance (Eq6-r Pro) Well, I'd like (Hope) to think Skywatcher buys direct from Prolific ? :-)

Hi Avo,

Yep, I guessed it was vnc or similar :-)

I'm just saying is there APPEARS to be something flakey going on in relationship to the pl2303 driver.

Do you know if your Pegasus is using the "standard" Prolific pl2303 driver ? It would just be interesting to know

Hi nMac,

the range of experiences with all this stuff is really quite odd. Makes you wonder if it just all depends on which side of the bed you got out of :-)

@ Avo

forgot to say that this looks like a Prolific pl2303 driver problem specifically

Hi Avo,

I've messed around quite a lot with this and it's all a tad confusing :-( - for something so apparently simple it's bizarre ! I now strongly suspect that in this case it is a buggy driver implementation. I don't know which piece has the dodgy implementation, whether it be Astroberry/Debian/INDI et al or a straight defect in this particular driver.

I've used FTDI, Prolific, and the bargain bucket jobs for MANY years. I've never had a problem like this.
I'm pretty sure it's not the prolific hardware per se. If it was, they'd be out of business :-)

Looks like my options are buy or make something.

I have the bits to make something, just can't locate a verified pin-out diagram. Looks like FLO will be getting an order :-)

Oh, thanks for taking the time to make the screen shot.

@Hy.

Thanks for the thought. I may ultimately have to resort to something like this.

Hi PDB.

I just looked for the file at the location you suggested and it doesn't exist.

Thanks for the suggestion though - another tool in the bag :-)

Yes, I'm running a Mac and remoting into a pi running Astroberry.

Oh well. Onwards and upwards.....

Hello Hy. Many thanks for your suggestions :-)

Yes, there are a few ways I could go with this. I have tried connecting to the mount using AstroTelescope which worked fine (I needed to know if my mount was broken so I went back to the fundamentals) although it would only connect at 9600 bps.

I happen to have an FTDI FT232 ttl cable and I'm wondering if I can "spoof" INDI by making it think it has an FTDI interface. As I say, I'm not sure how to proceed. I need to sit and think for a while - but not tonight, it's way past my bedtime and my head hurts :-)

Thanks again for your suggestions, I'll add them to the mix - so to speak.

As they say. Tomorrow's another day.

Best regards,

cas

Hello. Very interesting information. Unfortunately I'm in this situation. I have a Moonlight focuser which uses the FTDI driver and my mount (EQ6-R Pro) uses the Prolific driver. I can't get my mount connected :-( I'm not sure how to proceed.

Any suggestions you might have will be gratefully recieved. Both of these devices are quite expensive and I just can't afford to replace either.

No one said it would be easy :-)

Cool.

Thanks for your help

Hi,

thanks for the useful warning.

I'll hunt around for the firmware.

Many thanks,

Hi,

thanks for the reply. Sorry, more questions.......

Did you have to compile from source ?
Are you Plate-Solving on the Pi ?
Is buster easy to get hold of ? (Not Pi savvy) Been doing stuff on Arduino.

Grateful if you have time to reply.
