[GreenKeys] Siemens T-1000Z teletype Connection to Demodulator

[W2HX]

Fred. Others here will certainly know more about this unit. I did a little googling and from what I can find, this unit only goes down to 50 baud. For regular USA hams, we use 45.45. I think a friend of mine who has a siemens had to replace the crystal for the baud rate generator to get it down to 45 baud. Regarding the physical connections, others will have to help you there.

Subject: [GreenKeys] Siemens T-1000Z teletype Connection to Demodulator

I have almost finished restoring my T1000Z - took me 4 months
I took it completely apart(not the mechanical printer mechanism). I changed all the electrolytics and tantalum caps, except for the 2 large electrolytic caps in the power supply sitting in those black plastic cylinders.
I have it working on local loop.

How do I connect it to a demodulator ? There was a sticker on the case that said 60vdc and 40 mA.
Is there a power supply inside that has this voltage ? There must be something, because it works on local mode.
There is a cable that comes out and it has multiple colored wires. The 1/4" male plug was ripped off accidentally,
I have no idea how to connect this to my dovetron terminal unit, or my HAL ST-6000
The cable has wires with the following wires:
red - NC
blue - NC
orange - NC
grey - NC
white - this was connected somehow to the jack
green - this was connected somehow to the jack
yellow and brown wires - these were connected together and to the jack going to the demodulator

Need help please !
I have worked so hard on this unit to get it to this point. It would be shame if I could not get it to work.
Thanks, Fred
