had this loads of times in the last 20 years and also usb hubs. and its so weird how they can stop working with just 1 camera but work fine on another and vice versa. USB has always been unreliable for me and imaging. And doesnt seem to matter if they are cheap or expensive just seems totally random.

@sonnyedmonds7993 Месяц назад

In addition to all of that, those tiny connectors inside the plugs get a film on them over time. A simple fix is often to just exercise the connectors by unplugging and reinserting them a few times. It has almost become a routine for me. My ASI 1600MM Pro has been having some cooling anomalies, getting hot pixel scatter in my imaging files. Today I simply unplugged and reinserted all my USB and Power connectors for the win. Why is that? Because it wipes the contacts off and makes good contact again. I've replaced many, many cables over the years.

Indeed, in Europe a well known brand is "kontakt" there is an anti corrosion one : "61" most used for selector switches on tuners, look for "kontakt 600" and amplifiers.

@simontregear2365 Месяц назад

Thanks Cuiv. I had a similar problem that cost me a month or so of observation. Looking back, my "cable management" was probably the problem - all tightly bundled to have clean management.

@CuivTheLazyGeek Месяц назад

Yeah sometimes it's better to have cables that don't look good but have some nice slack in them!

@rickbattle5706 Месяц назад

The fundamental issue is very simple. USB connectors were designed to be used with static computers and peripherals. In other words they do not move and they are not subject to wind or setup and takedown. The male connectors are inserted 90° to the flat surface of the female receptacle and the male connectors never move. Through cable management around your OTA we sometimes string the cables too tightly thus pulling the male connector out of 90° alignment and thus makes an intermittent or no connection. My experience was with PHD2 where the guide camera kept disconnection from Windows and you hear that obnoxious, incessant chime from Windows. Maddening. The cure is to add extra length to the cable run and carefully tie-wrap the cables so they male connector is properly aligned and never moves. In radio threaded connectors with a screw tighten ring are used to prevents such a problem. Maybe the Astro industry could take a hint.

@CuivTheLazyGeek Месяц назад

Thanks Rick, that makes sense too - I need to recheck all my cables for such issues... While still making sure they won't snag... or get influenced by wind!

@joajoajoaquin Месяц назад

In addition to the color, check the number of contacts. You can find blue connectors in the wild with only 4 contacts. So you get a blue USB-2

@CuivTheLazyGeek Месяц назад

Oh man, now that is plain evil from the manufacturer!! Thanks for the tip!

@sonnyedmonds7993 Месяц назад

My ASI1600MM Pro has blue plastic indicating USB3 connectors. Had a lot of trouble with it until a fellow imager suggested to put the umbilical cable from my mount into a USB2 port, Fixed that problem ever since on my laptop. ZWO needs to realize blue plastic does not a USB3 make. So, now I have USB3 cables and a USB3 powered hub feeding a USB2 port on my computer. I don't have a problem with that because I take long exposures. So, my systems have plenty of time to download images and get their control pulses.

@MichaelGoldstein-jb4ti Месяц назад

I tell newbies to buy cables that are long enough, but no longer than you need, and never buy 1. Always buy 2. That way you've got a spare for debugging and replacement. Also, you can buy cables with right angle connectors in the correct orientation that ease strain on the connections, and makes the cable less likely to snag. While a cable can fail any time, it's particularly a problem in cold weather. Below freezing temps make them brittle.

@CuivTheLazyGeek Месяц назад

@Psychlist1972 Месяц назад

I only use L-com cables now (no affiliation other than a happy user). They are more expensive, but have yet to fail, and are even offered in armored versions (I use the plastic armored version for my main camera connection). They are also clear about which USB-C cables support which USB protocols. I've had plenty of Amazon cables, even "good" ones, fail. One would fail whenever I had a meridian flip. But astrophotography image transfer has like zero ability to recover from errors. The same crappy cables cause things like retransmits when used for other things, but with astro, we see the worst case. The flat cables with ZWO cameras go right in the bin when I get them. You'll find that many of those "thick" cables aren't doing you any favors; they are just using a thick rubber coating to make you think they are more robust, no additional shielding or thicker signal wires.

@siberx4 Месяц назад

So it's possible what happened here is that the USB 2.0 data pins in your faulty cable broke, but the high-speed USB 3.0 pairs were still intact. These two channels operate mostly independently in a USB3+ device, so if the main sensor chip lives on the USB3 (xHCI) bus and the built-in hub and built-in guide chip live on the USB 2.0 (EHCI) bus, then a partial failure like this could happen and would result in symptoms like you saw. Definitely agree that shielding is substantially more challenging in flat cables than rounded ones. It's _possible_ to make a quality flat cable, but a lot more difficult, so if you don't need the flexibility, stick to the rounded ones for high data rates where possible. USB C to C cables are definitely very challenging; there's no clear identification in the general case, and manufacturers are very inconsistent about colour codes and labels as to what each cable will or won't do. I make a point of marking any cables I have bought and confirmed as proper USB 3 cables with a small "3" so I don't get confused down the road, but in general the 3+ cables are somewhat thicker/stiffer. If your C to C cable is quite flexible, it's likely a 2.0-only cable. If the cable is 15ft or longer, it's almost certainly a 2.0-only cable! Even 10ft is tricky for USB 3.0+ speeds.

@VisionCommunications Месяц назад

This is very helpful! One of the reasons I don't bunch my cables together in the interest of so-called "cable management. I learned from the world of audio and video production that power cables should not be coupled with signal cables. The power cables can interfere with the signal cables. It seems your issue was a bad cable. I do make sure that none of my cables gets snagged while slewing, but "cable management" is for more permanent installations or for pictures of gear that people put on the Internet, so other people won't complain about a lack of cable management! :-)

@CuivTheLazyGeek Месяц назад

Good point! I will say that some cable management is good in windy conditions, and when they can get snagged somewhere - but sometimes it's done purely for aesthetic reasons :)

@VisionCommunications Месяц назад

@@CuivTheLazyGeek Yes, people do it mainly for aesthetic reasons (to post pictures of their setup). Typically I don't show my gear set up since it only invites gripes from the "cable management police." :-) In actual use, I never have a problem with my cables.

Sometimes it's not the cable but the usb port. If look with a strong magnifying glass or very close up camera, you'll notice two bendable clips on one side of the port that should push up onto the cable, that might be pushed in, giving you that loose cable feel and sometimes causing disconnects. With some small needle thingy, try bending it a little back towards the cable side to give the slot that new cable, tight feel. I hope you understand because it hard to explain.

A great video Lord Cuiv 😊 I’ve spent my working life (over 40 years) troubleshooting and diagnosing data communications network faults and problems. Whilst there are numerous methodologies, I generally find that starting at the lowest level and working up (reference the OSI 7 layer model) provides a good basis for fault finding. Ensuring the most basic elements function first - physical connections and interfaces, ensuring all wires in an ethernet or USB cable are intact, providing signal etc. and then moving on up.

@cosmoscarl4332 Месяц назад

My latest problem has been the length of my USB 3 cables. The DSLR worked fine with my four meter cables but not when I tried to use the new dedicated QHY 183 M camera. From my former experience as an electrician I realized the longer the cable, the more copper conductor, the more voltage drop and signal loss due to increasing resistance in the longer conductors. Interference usually isn't a problem unless you're running power cables with data cables, as USB cables have braided shields around them that carry unwanted signals to ground. AC and DC power cables create electromagnetic fields that can corrupt data pulses. The fields surround the cables when they're energized. The fix, I believe, is to use a powered USB hub, like Pegasus Astro power box. This should boost the signal from the camera, although im sure it has it's limitations as well. Another option I just learned about are "powered" USB cables. Basically the same thing, just built into the cable itself.

@memyselfandi906 Месяц назад

Cuiv! You fantastic creature! It's all your fault 😊 You got me in to this.

And Yes, understanding collimation is a "thing" .. #$/:-/ Anyhoo, last session my focuser didn't connect. It did before right? Spent a few hours with the Device Manager open,( restarting windows., reinstalling Ascom driver etc) indeed and almost gave up, until I unplugged the cable and plugged it in the usb port next to it! It pinged, opened a fresh unused COM port and worked happily all night. Check out the focuser by the way, an EAF GEMINI 2 pro on Ali. Backlash is about 30 steps. Above all I'd like to thank you. I would not have been where I am without you. So, thank you! Clear skies!

I am about to spend money on Cable Mod cables just because you are guarenteed quality.

@robertgrenader858 Месяц назад

I always throw away those cheap OEM flat cables from ZWO, and replace them with high quality connectors. The other issue that can contribute to cable shorts is extreme 90 deg bends at the connectors.

Short cables with good shielding is the key, and only use USB3 if you absolutely need to... And dont bend cold cables!

And then, exactly the same problem happened, even with a beefier power supply and brand new eagle. Decided to buy two new usb cables. First one, same problem AGAIN, but the other one finally fixed it and I havent had a single mount disconnection issue since.

Try a ferrite bead on your cables before you trash them. It’s a type of choke that suppresses high end electronic noise. Also, make sure you don’t have kinks or lots of slack.

An alternate theory ( if you haven't thrown that cable away yet ), Your device manager was in a high refresh rate due to a port conflict. If your computer had already assigned a port for the focuser and then you added the ASI2600 MC Pro Duo, on power up it detected the guide camera and assigned it the same port as the focuser and that's when it went down hill. The cable may still be an issue but I think the port assignment was also an issue. Clear skies #LookUpItsTheOnlyWayOut.

My worst nightmare struck when my first mount the EQM35-Pro's DEC wire snagged on an azimuth bolt head and it stopped the mount while I was slewing. I had never had this issue since I had the mount for almost a year. It bent the pins inside the cable and I had to use pliers to straighten them as much as I could but they are still bent. They are really hard to bend back. I just put in an order for my second mount, a budget harmonic drive that has more capacity. I got the new UMi 17R with FRAM on preorder. Hope you can review this one as well, Cuiv!

@richardwitzke5492 8 дней назад

I agree that the flat cables supplied by ZWO lack shielding, but they are also weak (wire is too thin). When I first bought a ZWO camera I liked this flat design cable, since it bundled nicely in a cable management scheme, but within several months one failed, then another and then another. I tried them on other devices and they did not work. I have since gone to a good quality slender, round, braided design of cable with no issues after several years use. Sometimes it is even how loose the USB plug fits that will make it fail. On the female ports on my laptop, for instance, I have used a dental pick to bend the springy retaining tangs for improved grip (computer powered off of course).

@michaelstolz1797 Месяц назад

I only realized this year that USB-C cables are actually active components with logic boards in their plugs. They can negotiate speed and voltage with the connector they are plugged in! This was a revelation to me, which was very important for example for getting a very compact and reliable 12V power supply out of a 12V selecting cable in connection with a (quite new) powerbank. That cable itself basically negotiates with the powerbank, that the powerbank should provide 12V, not 5V, and presto!

@RobertKarlBerta Месяц назад

That is the difference between Android, Windows, and Apple. Android has the circuitry in their boxes and NOT the cable. That is why Apple cables cost more.... the Android cables are the way they should have implemented it.... KISS method that Apple failed to follow.

@ysl109812 Месяц назад

Thanks for the great video. Cable failures have happened to me way too often and ruined many of my imaging hours. It is particular annoying when the issue lies with the powebox plug. It could be much harder to find the culprit. Now I have developed a method whenever this happens. That is to unplug all cables and start with only the camera USB 3 cable and plug them back in one by one to pinpoint where the issue is. It could take some time and sometimes the results can be inconsistent, but still a little more systematic and useful than blindly plugging cables in and out as I did before.

@CuivTheLazyGeek Месяц назад

Oooh Nice! This is a good, systematic way of diagnosing, it would have prevented me a lot of pain!

@victortapia-montano8114 Месяц назад

You gotta loop the cables so that they are not tight at the bends. Replace the cables with high-quality cables that are nylon braided and shielded. ZWO has a warning for ASAIR not to run the power cables near its antenna. The cables provided by manuifacturers are the cheapest.

@CuivTheLazyGeek Месяц назад

Yes that makes sense! I've always wondered about those braided cables - are they well shielded? I mean it can't be worse than those flat cables :)

@victortapia-montano8114 Месяц назад

@@CuivTheLazyGeek It depends. You have to do your research Like the filters ;) . I have found good quality cables in Amazon that have lasted the Arizona heat and rough handling. I always use shielded cables anytime these will be close to electric carrying cables or power supplies. Yes, these are less flexible and tend to be thicker. You can also use angled connectors to reduce stress on the cables. Not sure why manufacturers don't convert to USB-C which is easier. Just make sure they are labeled SS (Super Speed) for USB 3 or above. Braided cables offer greater durability. and prevent the mini copper cables inside from tearing. Lastly, if the cable is cheap, it is not going to last.

@brod5352 Месяц назад

Interesting topic. I'll have to check my wire bundle and see if I have my camera cables in close proximity. You know I was having problems with my Stellarmate Pro not being able to secure a GPS lock. No matter what I did it just would not lock. So I contacted Stellarmate and they told me to unplug all my USB 3.0 devices and then turn on the Stallarmate Pro. Evidently there is an issue with USB 3.0 only that causes problems with the GPS. Because as soon I did as they suggested, I got an immediate GPS Lock. And it stayed locked even after I plugged my cameras back in. For one of the more simple pieces of equipment, it sure can be a pain in the back side when they want to. ;o)

I had similar issues with an aftermarket cable that worked fine with the 294MC Pro with an ASIAir not working with a 585 MC Pro with the same setup. Switching to the red cable that came with the 585 solved it as well. Going back to the 294 MC Pro and the older cable continued to work fine. I think these cameras can just be more picky about their cables - sometimes they work with cheaper cables, sometimes they don't. Note that the symptom for me was that it would take about 2-5 photos just fine, then stop working. I'd have to unplug/plug it back in again. I guess it could be interference as you suggested as well.

@pompeymonkey3271 Месяц назад

You are right to narrow the issues down to the reliability of the USB connections. However, I am convinced that the real issue lies in the connectors! USB connections are really not designed to function when the cables are moved all the time. The worst culprits for failure are where the socket relies on just the soldered connection to the PCB for mechanical strength. This is not isolated to the astro-equipment industry: Think Walkman jack sockets or mobile phones... :( The only exception I have seen in astronomy equipment is the captive mini USB to the Polemaster, of all things. The irony being that you only need to have it connected occasionally.

I lost 5 hours of imaging time one night because my mount's power adapter's North America AC plug adapter. It had slipped out far enough to not connect, but not far enough to drop out of its slot on the AC adapter. Meanwhile, my mount still had power. It was drawing power through its connection to my StellarMate OS Raspberry Pi. I could use the hand controller to slew the mount manually just fine. But whenever the Stellarmate commanded the mount to slew, it wouldn't move. I also had a USB power adapter plugged into the AC outlet alongside the mount's adapter. I was concerned that maybe something weird was happening between the mount's ground and the USB's ground (I was clutching at straws after hours of faffing around!) So I grabbed my portable power pack, disconnected the power cable from the mount and put in the cigarette lighter power adapter, plugged the various other devices into the power pack's USB power ports, and I was able to start all over again with aligning the mount, polar alignment, etc. and get in 90 minutes of imaging before closing up shop for the night. It was when I was cleaning up that I picked up the mount's AC adapter and had the AC plug fall out onto the ground. I have now glued the North America adapter into its slot with about ten pounds of urethane adhesive. Never again!
