9755 ATC Console Pin-Out

[jivinjoe]

Hello everyone - Im adding a console phone to my site and they no longer sell the cable that goes from the 9755 ATC to a break out box. I'm looking for the pin-out for the Din plug on the back on the 9755 ATC so I can make my own cable. Can anyone help me out?
Also looking for the command to stop the RPV errors showing up all the time.

Thanks for any help you can provide

OK, I have some experience with these PITA assemblies, and here is what I've found.... If you're still lucky enough to be running the original power supplies that came with the console all you need is a flat 8-wire silver satin line cord with RJ45 plugs on the ends in the straight through configuration, or just use a hunk of CAT5 cable and wire it like it was a straight thru line cord.

However, I have had several power supplies fail, and I have been buying replacement power supplies from Black Box Resale, and those NEW power supplies will no longer work with that silver satin straight thru cord. Took me a few hours to figure that out. Finally I said "I wonder" and went and grabbed a standard CAT5 patch cord out of the data closet just for giggles, and that worked. Will not work with the old original power supplies tho...

Hope that helps.

I have a new power supply from blackbox that just has the screw terminals. But the pin-out I need is for the 8 pin din connector on the back on the 9755 ATC console phone. From there it will go to a break out box I will make for input from power supply and wiring back to the ATC card in the CBX. I know I need tip and ring and then 2 data, 2 for power. I just cant find the information for 8 pin din connector so I can solder up my own custom cable.

the "Newest" new spare I have just has a cord coming out with 2 flat wire connectors on it designed to go under the screws on the jack just like the original. You should be able to open up the existing wiring block and connect those two wires in place of the two that were in there from the original power supply and be done.

My second most recent power supply that I just used had an RJ45 connector on the power supply. That connects to the bottom of the console using a standard CAT5 patch cord (not supplied). Then the other wire from the power supply had an RJ45 phone jack block on it that the power wires were already punched down on. I had to make my own cable that had an RJ11 on one end to go into the phone jack and on the loose wire end I had to punch down the blue pair to the supplied wiring block - then I was good to go with that one.

The crap just comes in a bag with no directions - it was more than a little annoying!!

Ok Im must be not be explaining what I need correctly. The 9755 ATC Console phone has a 8 pin din plug you have to use to hook it up, I do not have that cable and they do not sell it anymore, so Im making one. I have the solder 8 pin din but I need to know the pin-out on the back on the phone. Here is a link to a picture to help. Its the round plug that I need the pin-out for.

Nope, my fault. 9755 and 9765 are very close sounding )

Let me go into the system install manuals and see if I can find a pinout.

I have never seen a pin out of the Din Plug, I would take one of the ones that is working and meter it. To stop your RPV errors go into DIA and DIS TEST RPV, when ever ypu want to check a Rolmphone just EN TEST RPV

Thanks for the info on clearing the RPV erros. I have a existing cable I can take apart and check but then the only console will be down. Maybe I can do that some morning, shouldn't take that long. But we know what happens when you say that lol

Just turn the ATC off before you unplug the cord

Well I looked at the Din plug this morning and it has a cap that is crimped and soldered on so I can't open it and look at the pin-out. Dang. I'll wait a couple days and see if anybody knows it. If not then I might destroy it to find out.

I have the Siemens CD set, but I don't have the Archive disk and the 9755 docs look to be on that disk. All I have are the setup docs for the 9004 and 9005 stuff and those just talk about programming and not the hardware. Sorry I wasn't paying attention the first time I read your post.

As far as testing the cable, as long as they don't have any wire that go like a serial cable where one pin on one side goes to 2 pins on the other side or something else strange, you should just be able to take an ohm-meter and touch one pin on one side and see where it goes on the other. I guess even if one pin did go to more than one on the other end you would be able to tell that. Also be sure to look for pins on the same side of the plug that are just jumpered together and don't go across. An ohm-meter with a beeper on it is even more helpful!

Depending on the pinout, there used to be some audio equipment several moons ago that used DIN cables to connect components, and you might be able to find something on one of the audiophile geek sites if it's just a straight thru cable or something...

Did you have any luck finding the pin-outs? The only thing I found was from the original console for the 8000, doesn't really help as you need the DIN jack connections. The 9751 Maintenance Manual only provides drawings and a description of the ATC. The last resort may to take it apart and hopefully see the same colors on the jackmsuch as wh/bl for T & R, wh/or for data, and maybe gn/wh for power. The old ATCs actually had an additional pair, wh/bn for lamp power.

I wonder how I can attach part of the old ATC document that may help slightly, copy and paste won't work. Clicking picture just brings up script prompt.

I was able to set up some down time, then I ohmed out the cable. I got the console install and up and running. Only thing I can't change yet is when both console are on its seems to alternate calls between them both. So I just have to make sure they put the console in night tone when they are not at it.

 

[PERRYPJ]

That's they way they work alternating back and forth
