I can confidently confirm that indeed the R- terminal on the 8ZSA is the positive connection.
This is extremely important when dealing with a situation where a wire was cut somewhere between the amplifier and speaker.
When trying to use a common ground to keep the speakers in stereo, you will have to use L+ and R- for the left and right positive connections.
Then, you can use L- or R+ for the single negative connection.
I know that this doesn't happen every day, and most people would just connect the speakers together as a mono zone.
However, it can be done keeping stereo intact.
Good luck out there,
Brian?

Re: AJA Kumo router control
Same here. The one Control Works (AJA) is offering costs $300.
If anyone has written one (especially for the KUMO 1616 SDI), I'd be extremely grateful, since I'm still pretty green at this.
Thanks-a-bunch in adv.?

Re: Subpage Reference List, Item Visibility
I've had something similar happen where I needed to stagger the visibility joins so that all the items would show up.

The visibility of individual items on a subpage reference list is controlled.
The reference has 1 adv. button. Text on the button are formatted serial joins.
Digital Joins 1 and Serial Joins 1 and 2.
The list vertical with 32 items. Only 7.8 of the items (the 8th is a bit cut off) are visible at any given time.?
The list shows up fine if all items are made visible.
I press a button that shortens the list making items 1-4 visible, 5-12 hidden, 13-16 visible, 17-32 hidden.
But I only see the top 4 items.
If I show all again, then scroll the list to the 13th item, then make press the same button that hides the items, then I see items 13-16.
I've also tried hiding the entire list using the visible join on the entire smart graphics for 0.8 seconds using the out* of a one shot. To essentially try and redraw the list but that doesn't work.?
Also if I hide the entire subpage by calling up another, and then coming back, items 13-16 are visible.
Any ideas??

Re: I'm losing my mind USB to C cables
That "chip" is a USB E-Marker chip. It's supposed to simplify connectivity by comparing the requirements of the source and the sink, as well as the cable's capabilities, to ensure power and data is safely and effectively transmitted over the cable. It may be that the combination of requirements and capabilities of the card reader, the Mac and the cable don't jive or it could also be the cable sucks which is often the case. Could also be the Mac, they do their own thing over there (which isn't always a bad thing). Stick with reputable brands such as Anker, Cable Matters, OWC, even Apple. I have seen lots of issues with other, cheap cables. And if you deal with USB often you may want to consider getting a USB tester like the FNIRSI FNB58. This device will read the E-Marker chips in cables and display their capabilities as well as those of the source and sink. Good tool to have if you interface with USB on the regular.?

So, I have been given an official answer from True Blue, and it is that it was purposefully designed this way.
They didn't explain exactly what they were doing inside, but it is very interesting indeed.
This is the first time that I've encountered this.
However, it is also the first time that I've had a 4-condutor wire with only 3 useful conductors since NAX was introduced.
I guess that I will wire the right speaker positive wire to the right negative terminal and forget this ever happened.

Re: I'm losing my mind USB to C cables
Thanks.? It's the OTG part of that adapter that makes the difference.? After scratching my head with a pitchfork for a couple of days, I cut open the "C" end of one of my cables and sure enough, there's a tiny circuit board inside.? I ordered a package of adapters to keep on hand.? I'll let you know if it does in fact solve my particular problem.

That was a thought that I had, but other "real" amplifier manufacturers use the same terminals for bridging.
They handle it by using internal relays when bridge mode is activated.
Internal relays seem like the proper way of handling this.
Could Crestron be reversing the phase internally before the signal is sent to the right speaker only to be "un-reversed"?
All of it seems a bit odd.

Hi Folks,
I never worked with those amplifiers, just guessing: this is related to the usage of bridge mode.
In bridge mode, the loudspeaker is connected to the positive output pin of the left channel and the negative output pin of the right channel.
If both negative amp pins would be grounded, bridge mode would have to be implemented differently (connecting the loudspeaker between the two positive pins and inverting the signal to the right channel internally).
The positive pin of the right amp being grounded rather then the negative pin is just a matter of circuit design...
Best regards

Re: Mitsubishi mini split and Crestron Home
Going down the rabbit hole on this Mitsubishi heat pump has led me to discover there is a serial port under the cover meant for a cloud integration accessory and somebody has worked out the protocol.? It¡¯s simple enough someone could write a S# driver for it.? It would need a TTL to RS232 voltage adapter to connect to Crestron.? Mike

Hello All,
Maybe someone can shed some light on this one!
So, being an old fart in the industry, I may have dealt with cut wires or drywall screw through a wire just a couple of times before.
Naturally, I have solutions for this.? Step 1 ... determine just how many wires are good on the 4-conductor speaker wire.
Excellent, we have 3 good conductors.? So, there are 2 options.
1. Just connect the speakers in parallel, set the zone to mono, and everything is happy at ~4 Ohms.
2. Use a common ground because all of the negatives are typically commonly grounded on a multi-channel amp or receiver.? Now we still get stereo!
Because I ran into this exact scenario today, I decided to test the 8ZSA to verify the chassis ground situation.
I broke out the old multimeter, connected one terminal to the chassis ground, and tested all negative connections on the 8ZSA.
All RCA connections have the sleeve grounded as per usual.
Balanced phoenix connectors are grounded as well.
Left speaker?? Yup ... it's negative is showing a short with the chassis ground.
Surely the right speaker is grounded similarly, correct?? No, it is not.
For some reason, the right positive terminal is connected to the chassis ground.
In my almost 30 years I have never seen anything like this.
Just to make sure I wasn't losing my mind; I called some other members of our team on jobs in different stages of completion.
Every single 8ZSA that was checked has the right positive speaker terminals connected to chassis ground.
Can anyone think of a reason that this would be the case?
Is there some new "Bob Carver" form of amplification that has 1 speaker grounded to the negative terminal and the other grounded to the positive?
It would seem to me like the right speakers would be out of phase.
I have not had the spare time to place 2 speakers face to face, play a specific frequency from my tone generator, and listen for the cancelation.
True Blue just kept asking me if there was an actual problem.
Umm ... it depends if every right speaker on every 8ZSA is out of phase!
Please help!

Re: RTSP AVER camera on TSW/TS/XPANEL (embedded video)
In Xpanel it is not possible to visualise any stream, in TSW panels without problems, you must in VtPro select Source ID H.264 of Embedded Video.
El 7 may 2024, 13:38 +0200, joan.fuhrmann@... <joan.fuhrmann@...>, escribi¨®:
Hello,
Do you have any feedback on using RTSP streaming on an Xpanel/TSW interface of an AVER camera (550, 520, PTC310...)?
According to the manufacturer's specifications, the RTSP stream is H264. However, I am unable to display the video stream (embedded video) on a TSW/TS/XPANEL.
For your information, the stream is accessible from VLC or PotPlayer, "Open on page flip" is also activated in VTPRO, and I have also tried using "MJPEG VIEWER" without success.
Thank you for your help.

Hello S¨¦bastien
I have only managed to make button changes, which allows them to be made without registering, but I have not been able to register according to the API, I don't know how to do it.
Do you have any samples of this, or could you tell me how to do it?
Thanks in advance.

Hello Juan,
Everything is done with http requests using the documented API.
You have to login first to get a session Id. This session id has to be stored in the module memory. You have to use it as a cookie for each following requests.
