Thanks for the recommendations! Always good to know where to get good stuff.

Re: APCC PRO and Virtual Ports

Ray Gralak
 

Hi Jack,

My only suggestion is that you can try increasing the timeout in the AP V2 driver. APCC uses a third-party component for the virtual ports in APCC. The component is exactly the same for both APCC Standard and Pro, and there should be no reason that higher virtual COM port numbers would act differently than lower port numbers.

Ray,

I modified the sample horizon file you sent to me and now have the horizon for my location input into APCC PRO.
But now I have a new issue.

I have been using APCC Standard for years to control my AP1600 using SkyTools PRO V3 and now SkyTools V4
Imaging. I have the mount connected to the computer using the Serial/USB connection on COM3.
I have two Virtual Ports created - COM6 and COM 12. I have been connecting SkyTools to the mount using
ASCOM V2 Telescope Driver - v5.30.10 on COM12 and occasionally I get a lost communication error message,
SkyTools shuts down, and I then have to restart SkyTools and reconnect it. I thought that maybe since I was on
COM12, that was the problem. So I created COM31, went into the ACSOM V2 Telescope Driver setup for
SkyTools, changed the COM port from 12 to 31, checked the port and it was found. But when I went to connect
SkyTools to the mount, a connection could not be established.
I eventually went back to COM12 and it connected right away.

Any idea what the problem could be? I would like to use the higher COM numbers if possible.

Yours truly,

Jack

Re: Cable talk (with Linda Richman)

Dale,

I agree with you on just about everything you said. I've pretty much given
up on soldered connections too. And I too have recently discovered L-com
for USB cables. They're expensive, their shipping is expensive, and they
even add on a Tariff charge. But I'm really liking their cables and the
unbelievable selection they have.

Last night I was looking for a very specific kind of USB3 cable and just
couldn't find all the features I wanted in one cable. Even on their
website. So I gave in and opened a Chat session with them. And within
about 5 minutes the guy found me exactly what I was looking for -- which
doesn't show up on their website unless you have the actual part number. So
they even have more stuff than you can find on your own on their website.

Unfortunately the longest UltraFlex USB3 cable I found was 1.5m long. But
hey, I'm sure I'll find uses for a cable even that short.

Woody

Also, keep in mind it's not just the cable thickness by itself. The length of cable is also part of the equation (as well as if it's in a bundle, underground, if it's double insulated, etc.).

If you have a long cable run, you will need a thicker cable.

The advice of checking the voltage drop with a multimeter is a good way of checking it. Check it under the load conditions such as with motors running, dew heater on max and camera cooler on max during initial warm-up all at the same time.


Re: Power cable conductor gage (AWG) of

Looks like this thread is turning into a “free advice” private club party. Where do I sign up? I wanna laugh too! ;)

Putting it back on track, thanks to Jack for his detailed recommendations. They were almost all on my check list but maybe not on everyone’s.
 
My USB3 cables are no longer than 3ft from devices to hub and are good quality shielded TrippLite cable for the exact reasons you mentioned: signal integrity needs care at USB3 freqs.
 
All unused connectors are covered either by proper covers (or electrical tape until I get some).
 
The junction point of the mount power-wise will be with a harness cable I’ll make with PowerPole end terminals. One branch (to the mount) will be 18AWG and the other 16AWG to the PPBA via the TTM cable in the Mach2. The common end being a 14AWG (also terminated with PPole) to the battery.

No need for a distribution panel in my case, the PegasusPBA wired to the mount’s internal cabling does it all.

I’ll try to post a pic of my setup if I get to wake up before dusk tomorrow. Now is imaging time! :)

Re: Mach2 Slew Speed, Power, and Voltage Question #Mach2GTO

Greg McCall
 

Hi John,
That's excellent information and I much appreciate the detail. You have also raised something that I didn't consider yet with those popular power supply modules as I had not really seriously considered a 12v to 24v converter. You have also saved some effort in those current measurements so again, thanks for that detail.

(I wonder what the 12v current is just operating the Mach2 at 12v.  Something to watch next time. -- The AP spec of 5A minimum is not very helpful as you usually plan for a maximum both in power supply, cabling & fusing)

My LiFePO4 batteries use 14.6v but I know I can set the max on my chargers if needed and the float voltage is 13.8.

I also use a NUC with a 12v to 19v converter. It's designed to power a laptop in a car so I assumed it could handle at least the charge voltages of lead-acid. (just replaced the cigarette lighter plug with a powerpole connector)

cheers
Greg


Re: About APCC and ISS tracking and PC Time

Are any of these using the 1 PPS feature of GPS for better accuracy than the serial data stream?   

 

I’m not sure there is a practical difference but they all seemed to not have it, not sure if that’s a windows/USB thing, or just that they are a bit behind, or if there’s something expensive about it so it doesn’t show up in these products?

 

I went to buy one and felt like I was getting a CFL light bulb instead of LED – not awful, just not current.

@Dale & All,

The app came for free with the GPS dongle. Not very sophisticated. Thus probably missing out on DST. I asked NMEATime2 about preferences of COM over USB vs BT. BT seems to be deprecated. More interesting the 2sec gap between Win10 clock and GPS. I had used the sync with network in the MSFT clock settings popup just 5min prior. Alas I probably hadn't let the GPS soak for  long enough. Will try again.
