We use the Extron DTP HDMI 4k 230 tx and rx transceivers. The "230" means it can drive 230 feet of shielded twisted pair. The back of the transmitter looks like this:
and the manual can be found here.
Here is some documentation from the manual on the back panel.
We drive the power through the crestron, we do not drive the audio input, and we also do not use the "over dtp" as far as I can tell.
There are 10 Extron tx/rx pairs in the giant rack in PSC 0240. All 10 of them are transmitter (0240) receiver (lobby) pairs. 9 go to the video wall monitors, and the 10th goes to the little monitor on the wall to the right of the video wall in the lobby.
We use the Brightlink 4k 3x3 Video Wall Controller:
The rear has all of the relevant inputs: the bottom row of 9 outputs and the top row has inputs from a computer.
The bottom outputs are labeled "HDMI Out1" ... up to "HDMI Out9". The video wall has 9 monitors in a 3x3 matrix, so let's label them Top-Mid-Bot and L-M-R for rows and columns. Each monitor on the wall has an Extron rx unit, driven by the Extron tx unit in 0204, and each Extron tx has an HDMI input that comes from the Brightlink, and these are labeled A1, A2, A3, and etc B and C. Here's the mapping from the A1..3,B1..3,C1..3 to the video wall matrix:
| Left | Middle | Right | |
|---|---|---|---|
| Top | A1 | B1 | C1 |
| Mid | A2 | B2 | C2 |
| Bot | A3 | B3 | C3 |
Brightlink mapping of what HDMI cables (labeled A1, A2...) go into what Brighlink output is here:
| Out1 | Out2 | Out3 | Out4 | Out5 | Out6 | Out7 | Out8 | Out9 |
|---|---|---|---|---|---|---|---|---|
| A1 | B1 | C1 | A2 | B2 | C2 | A3 | B3 | C3 |
The Brightlink allows you to setup from either the front panel by pushing the white buttons, or using the remote, or using the web interface. We use the latter.
To use it, drag a laptop into 0204 and get a USB->Ethernet adapter and plug it into the blue cat6 cable that is connected into the "IP" input on the rear of the Brightlink. I used an Apple MacBook Pro, and I found that to connect to the Brightlink, I had to first turn Wifi off. Then open up the network settings and you should see the "USB 10/100/1000 LAB" interface and it should say Connected. Click on it and go into the TCP/IP setup and configure it for Manual IP, then use 192.168.1.8 and subnet mask 255.255.255.0. The Router is 192.168.1.1. Save that configuration, open up a browser, and browse to the Brightlink which is at 192.168.1.168. Login as admin and put in the password (Drew Baden, Jordan Goodman, Anne Suplee, and Steve Rolston know it). If that works, you should see this screen:
Here's how I got it to work:
