For those who want to make their own interface cable and are confused by the naming of the signals:
1 Eng TX+ (audio from cameras to intercom matrix)
2 Eng TX- (to intercom matrix)
3 Prod TX+(to intercom matrix)
4 Prod RX+ (from intercom matrix to cameras)
5 Prod RX- (from intercom matrix)
6 Prod TX- (to intercom matrix)
7 Eng RX+ (from intercom matrix)
8 Eng RX- (from intercom matrix)
If you only need one intercom channel you only need to connect pins 3-6.
Do you want to connect an RTS intercom system, then you cannot use a normal UTP cable to connect the intercom matrix analog (4-wire) port to the ATEM Constellation. Instead, cut one RJ45 connector of, get rid of the orange and brown wires, and connect the remaining wires like this:
pin 3: solid blue
pin 4: white-green
pin 5: green
pin 6: white-blue
This side connects to the ATEM Constellation.
To connect both the engineering and production channels to an RTS intercom system, take a second UTP cable and connect the blue and green pair to pins 1, 2, 7 and 8 in addition to the connections above as in the photo. Again, this side connects to the ATEM Constellation. The two other RJ45 connectors go into the analog (fourwire/AIO) sockets on the matrix.

I've tested this today (see photo) and both intercom channels now work flawlessly. I am using an RTS ODIN intercom system, ATEM Constellation and BMD URSA Broadcast cameras.

Several things to consider. The constellation does support both Production and Engineering channels that are additionally supported with the Studio/Cameara Fiber converter. None of the other ATEMS or the Talkback Converter 4K (or earlier) support the Engineering channel which is on SDI 13/14. Also, the Talkback Converter 4K cannot be used in conjunction with the Constellation Talkback. Either use one or the other as they do not pass everything back and forth. This is the same for other "Talkback Aware" ATEMS like the 2/4ME, TVS HD/HD Pro and 4K Pro. If you are using a separate Talkback Converter then you can shut off the use of SDI 13-16 on the Constellation in the Setup. I hope this helps.
