Hallo Zusammen

Ich habe zur Zeit 2x T100 auf dem Tisch. Der eine hat Kabelprobleme, und das muss ich mal untersuchen.
Der zweite ist schlimmer, weil mein Empfangmagnet unterbrochen ist. Hat einer von Euch vielleicht so ein Ding zu verkaufen?

Grüsse

I have a new machine here at the office - A Siemens T1000

Henning has already mentioned that the British T1000 is Special , so I will be needing lots of help to get this machine interfaced to I-Telex.

In general, are there any areas of the T1000 that have common issues that should be addressed before I go too far with interfacing the machine to my system?

Thanks
Sean

Hello Everybody.

Recently I did acquire my first Telex, a Siemens T100. There is no FSG, just the machine.
After opening it up (and before applying power), it looked pretty clean, no mice droppings, dust nests and the like.
So power was applied and the motor started, cranks rotated, the gears spins.
But, the keyboard is blocked, and the mechanism which holds the ribbon moves constantly up and down
(ribbon also moves slowly from left to right and vice versa).

Is this supposed to happen, or is the 60mA current a necessity to unblock the keyboard and also to stop
the up/down movement?

There is also a little difference of this machine compared to pictures from the internet, there is a little
extra device with a switch mounted inside, just right of the lamp bulb. Any idea what it's meaning is?
lifting the switch manually stops the motor.

Regards,

Ed

Hi all,

So, I have looked a little deeper into the BT Cheetah, from what I can see it is almost a perfect copy of the LO3000 - pictures to follow.

I have cleaned a lot of the dust and dirt from the PCBs inside the machine, and have repaired a problem with the X2 capacitor fitted inside the power supply.

This far, the power supply is giving all the correct supply rails to the motherboard (tested by removing the line interface card to get to the test points on the motherboard).

I have substituted the battery supply from the battery back up with my bench PSU just to make sure that everything is getting power where it should.

However, this is a poorly machine :( THe screen displays lots of random characters, and the illuminated keys on the keyboard are all illuminated.

I think there might be a problem with the CPU at the moment - either the eprom containing the data for the TP is dead, or the processor has a problem.

Does anyone with experience of the LO3000 have any ideas where...

Hi All,

My FS200 has a most annoying feature .

It gets through ribbons at an amazing rate, and once the ribbon is at end of travel, instead of stopping what it is doing, it decides to carry on overtyping the last character.

I wonder if the ribbon transport should auto reverse to keep cycling through the ribbon again and again?

Or, is there a setting I do not know about that can slow down the usage?

Is there a longer ribbon available - I think the ones I am using from eBay are much happier on a typewriter.

Cheers

Hello all, on my travels around England I managed to pick up a BT Cheetah, I have the machine, a modem, a box of paper and an operators manual.

Does anyone have a copy of the service manual? I suspect that there are some power supply related issues.

Has anyone managed to connect one of these to i-Telex?

Thanks
Sean

Hi all,

are there any I-Telex documents in English? While I can read a little German, this is proving to be quite hard work

Thanks

Greetings. This is Paul, from Arvada Colorado USA. I'm working hard to try to get my Teletype Model 32 working on i-Telex.

First remaining known problem: I have far too much loop current (78ma) so am awaiting some resistors to bring it down. The Teletype was designed for 60ma. I believe, and it might work for 50ma but I won't know until I test it. I may have to significantly rewire the teletype to get it to work with 40ma. Another i-Telex user has provided me instructions do just that. But before I start rewiring, I will try with resistors to bring down the loop current. I've ordered some resistors and am awaiting their arrival in the post.

Second remaining known problem is that the ethernet connection is not requesting DHCP from my router. My subnet is 192.168.1.x. When I look on the router, I do not see any new devices registering. After the power and test sequence is complete, the green LED is lit. The button does not seem to do anything. My german is not the best, but the...

hello you've ever solved the t1000 problem by accidentally shifting the left indent? maybe it is problem with micro switch.

Hi,

I will scan an English version of the book Einführung in die Fernschreibtechnik

Permission for Upload is pending by Siemens AG.

It will take a bit of time because I try to use a better scanner. If any info is needed urgently please PM me,
I will then provide an ad hoc scan by my MFG.

Now that I have a working system, and seeing as there is some interest from others in the UK, I wonder about the possibility of building an FSG from common available parts here in the UK?

Obviously now I understand how critical it is to be able to dial a number, and the ability to switch the TP on and off via the system is also a very good thing.

I guess at the moment the timing of the dialling pulses will be quite critical, but is there any technical reason why I could not base a UK FSG on the design of the Siemens unit I got from Henning?

Looking forward to any ideas regarding this.

Thanks
Sean

Just a picture of my system build - Eurocard is not that common in the UK, so getting sensible (for amateurs) prices on parts to build the enclosure is not so easy.

Subrack was a used item, and sourced at a UK Hamfest, new panels sourced from Reichelt.

Transformer for Power Supply sourced from eBay (much cheaper from Reichelt I have since found!)

Really easy system to build, and surprisingly simple to set up once everything is assembled (Note, polarity of connection to teleprinter is critical :) )

Cheers
Sean

Hello Fred,
I have a persistent problem with 'no subscriber directory'. The web server of i-telex card works smoothly, from outside work well.
After resetting i-telex, I can call for a while. Can help me an update?

Ok, so if I want to start making an I Telex system what do I need to do?

I see some hardware that is available on the main website, and I can understand some of the information that is included, but I do not know exactly the parts I will need.

Will this project require a fixed IP address to work, or is there some clever software that takes care of routing the data?

An English Idiot guide would be very useful :)

Thanks
Sean
