r/QSYS

Trying to control a Samsung QH75C commercial display via RS-232 from a Q-SYS NV-32 and can’t get power commands working.

Current setup:

• Samsung QH75C
• Q-SYS NV-32
• Direct RS-232 connection (DB9)
• Display ID set to 1
• Serial settings:
  • 9600
  • 8
  • None
  • 1

Commands being sent as Hex Bytes:

Power ON:
AA 11 01 01 01 14

Power OFF:
AA 11 01 01 00 13

I also used these commands [POWR1]\x0D and [POWR0]\x0D

I already verified:

• Q-SYS is transmitting now
• Hex mode enabled
• No CR/LF being added
• Tried swapping TX/RX
• Not using EX-LINK, using direct RS-232
• Samsung commercial display, not consumer TV
• Tried different BAUD Rate too up to 115200

So, I'm running Windows on a Mac using Parallels. It works great 98% of the time, including for QSYS programming.

When I'm on hardwired Ethernet, I can access cores no problem.

However, I'm now trying to access QSYS cores over wireless connections while onsite, and it's just... not working. I can ping the cores, I can go to their web pages, but QDS doesn't see them. At first I hoped it was something with the older tp-link router/access point I was using, so I ordered a new gl-iNet Beryl 7, and no dice. I have full connectivity except for whatever weird thing QSYS does to connect QDS to their cores.

Anyone have any experience, good or bad, access cores via wireless using Windows on Parallels?

So I’m dealing with the lyntec breaker panel plugin and the power control pins are toggle only. There is a status pin as well.

I’m looking to make a dedicated power on and off controls. What’s the best way to go about this?

I appreciate the help!

Any advantages of the having the av bridging license on the TSC-101-G3 as well?

Big "Thank You" to all of you guys; is this better?

Working with our QSYS vendor and getting conflicting answers.

On a NV21 being used as a decoder, can the local HDMI input be controlled?

For example, I have a NV21 Decoder connected to a TV. A digital signage unit is plugged into the NV21 HDMI input. I want to control the NV21 to sometimes use a network stream (from another NV21 acting as an encoder), but sometimes use the Digital Signage connected via the local HDMI.

This seems possible, and at first it was “no problem” but now I’m being told I need an addition NV-21 to encode the digital signage if I want to control it.

I can’t find a clear answer in the online product sheets or manual, so looking for Reddit to help! :-)

Is this feature specified somewhere I can point the vendor to as evidence?

Hi everyone. I finished my file and sent it, but the grader did not accept it. He said there were several mistakes, but I tested the file and saw that it worked. I also changed my file a few times because the grader did not accept it, but nothing changed. I want to know where I made mistakes.

1. Laptop switching — on my end, it works correctly.
2. Hold button — when you press it, it mutes all microphones and sends the lobby music to the far end. It works on my file.
3. UCI gain control — this is the part I really do not understand. Because I already configured it so that when the fader goes to the bottom, it mutes automatically. But the grader still did not accept it.
4. Q-LAN — the grader said that the music is not going to pass through Q-LAN, but that does not make sense to me. Because it is a simple setup, and you only need to select the transmitter name on the second core.

Maybe I did my file complex and grader just want me to simplify this. But it does not mean it is not work. Can someone have any idea what I have to do? Thanks.

I need to connect 24 NV-21 to a switch. These require PoE++ to work.

The QSYS NS26-1440++ has enough PoE++ ports and budget, but only had a 1Gbps SFP port. Will I be maxing out the bandwidth on the uplink? If I did two of these switches would 12 NV-21 max out the bandwidth on the uplink?

The NV-21 specs vary, and say estimated bandwidth is between 100-800Mbps.
