locked Connecting EXOS 2 PMC 8 to ASIair Pro #EXOS2 #TECHNICAL


 

Hi,
 
I emailed Bresser with this question earlier but they didn't know the answer & directed to ask here. 
Although I should have checked before I bought it      (I can still get a refund as I only have it on pre order) I was looking at ways to control my whole Astrophotography set up with my ES EXOS II PMC 8 mount and the ASIair Pro control box seemed perfect. 
But when I looked into how they both connect to each other & after countless searches on line all I could find was that I'd need a cable with an FTDI Chipset but that the chipset would need to be reprogrammed.
 
Unfortunately I'm not particularly technically minded & havnt a clue what an FTDI chipset is never mind how to reprogramme one.
I'd be very grateful if someone has any info on this or can at least point me in the right direction.
Better still would be an idiots guide to connecting them both 😬
 
Regards
 
Steve

Hey Tyler.

Pleas send me a procedure for linking the PMC8 & asiair .
This would make my life a whole lot easier.

Thanks

Dino

It was confusing at first for me as well. But the tech help at Explore Scientific pointed me in the right direction.
True you will need a DB9-USB w the FTDI chip set. I found them on Amazon. Theyre  Cheap.
Then we need to download the programs from their website.
If you go to the group.io and do a search for Asiar & PMC8 someone wrote a beautiful procedure.
I’m still waiting for my exes 2 because it’s backordered.
But for now contact tech support at Explorescientific.
Try emailing Tyler@explorescientific. He will help you.

Hi,

I am in a similar situation, so I tracked through the various messages and ended up with Marco's procedure in the files section for connecting my Exos 2 to ASIAIR Pro. Its very good even for the layman like me!

I already had a serial to usb cable as I have been running with a wired connection so, came to re programming the chip, downloaded the programme and scanned for devices and nothing.

Is it likely that having bought the cable from Amazon that it does not have a chipset but just looks like one? ( I paid about $12 UK £10)

I have been on a specialist site which sells them for about $30 and they are manufactured by FTDI.

Any advice would be greatly appreciated

Thanks
Alan

You have too k ow if you have a usb to serial converter cable.

1.  Do not plug it into the pmc8
2. Plug it into a pc
3.  Open the device manager.  See if it is listed there as a comm port or usb to serial. If not it is not a converter or you have not loaded a driver for it.  Check for that

I bought a great cable for 15$ so it is not impossible that your 12$ cable is an ftdi cable. But you should be able to tell as it will need to have a back shell over the DB9 connector inside of which is the chipset. Many have an led that lights when the thing is plugged into the computer.

Hi Wes,

thanks for the quick response.

The trouble is I am a Mac user, and windows is just so complicated, I have spent hours trying to get to the bottom of this, why cant the PMC8 just have a USB connection?
I have done as you asked and under device manager I have PORTS (COM & LPT) followed by Prolific USB to Serial Comm Port (COM4) is this correct?

I have checked for updates and Windows tells me I have the best driver, however the FTDI programmer cannot find the chipset (if there is one) when I do a scan under devices.
This cable works fine for connecting to ascom (Poth) and driving the scope around via CDC

This is doing my head in as I have read all the info on this forum in preparation to make sure I was heading in the right direction before I bought the ASIair pro, the guidance and the procedure on the files seems excellent

This hobby has more Cul de Sacs than you can shake a stick at in addition to the amount of money I've thrown at it......small steps I know :)

Well the prolific chip set has had issues I know. Jerry has stated the correct chip set to use is the FTDI.  My guess is the programming if the pin on the prolific didn’t work.  Try to get a cable with the Ftdi and see what you can accomplish.

The hobby is indeed one full of nooks and crannies.  And it can sure suck down some money.  

I bought the DTECH 10 ft usb to serial ftdi cable from Amazon.   I don’t use the asiair so can’t say how it might work with that.   It works like a charm in myPMC8 with windows.

If you are using windows you can download an ftdi driver from parallax web site.  See if that driver recognizes your usb to serial. It won’t if it’s a prolific.

Hi Wes,

The one thing about this hobby is it keeps you on your toes, I have learned so much and me in my twilight years.

I think I pretty much worked out that even tho it says serial it must have an FDTI chip, it looks like it has a chipset from the outside but looks can be deceiving!

Earlier I ordered a DTECH version which states it has a FTDI chip from Amazon, so glad that you endorse that. 

A slight aside, re drivers in Windows, is there a way of finding a list of loaded drivers in W10? I am pretty sure I down loaded the driver from FTDI but how do you check?

Many thanks
Alan

Hi,

I don't know if it will help anyone, but here's the schema of my astronomy setup. It seems to be working just fine.

Morning,

Thanks Paul for the schematic, it is very helpful, might be worth storing it in files along with the process for installing ASIair Pro
Just a small point, you're powering the mount from the ASIair?

Anyhows, just to let this small group know, received my new serial to USB cable WITH an FTDI chipset, followed the procedure and YES! it works.
Well I can move the mount, not tried anything else yet :)

Thanks to all for support and help

Hi All, 

Just FYI, I also power my mount (iExos100) from the ASIair Pro, as well as 2 dew heat strips which are controlled by the Air. What I believe ZWO does NOT recommend is powering the cooling function of a camera from the Air.

Alan, 

This schematic is so specific for my situation, but I found it handy when knowing for sure all cables were present where they needed to be :)
With the FTDI cable is essential you reverse the signal with the programming utility, but that is a breeze :)

The PMC-8 is indeed powered by the Asiair, and I haven't found any issues so far.

The dew strips need a lot of Amperes, I'm not sure it's a wise decision to power that by the Asiair. I had a seperate power adapter with too few mA's and the strips wouldn't warm up at all. With a 5A dedicated power adapter I have no trouble keeping my lenses warm.
