What do I need to start an I-Telex system Thema ist als GELÖST markiert

[M1ECY]

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

Hi Sean,

If you want a "real" I-Telex you need at least:

- an internet connection with a real IPV4 adress
- you must be able to configure a port-forwarding on your router

You do no need a fixed IP adress because I-Telex includes a DDNS Client.

concerning hardware you need:

- a power supply 2x 15V AC approx 1A each
- a backplane
- power regulator card (SV-Karte)
- an I-Telex-card (I-Telex Ethernet card)
- a TW39 card for the teleprinter.

You will also need a "FSG or Fernschaltgerät" for your FS220.

Johannes has a page detailing it: http://francokok.com/index.php/en/i-telex

PS: If you want to start small, there is a simple interface based on Arduino components.

It lacks most of the features of the modular I-Telex and connects only one TW39 teleprinter , but is fairly simple to build.

It lacks most of the features of the modular I-Telex and connects only one TW39 teleprinter , but is fairly simple to build.

But if you use this you will need either a fixed (static) IPv4 Adresses or an external DynDNS service.

Ok, I think the proper I-Telex Hardware solution is a better way to go - Whilst I enjoy fiddling around making things work, there is a good solution already available - I think I will try this. Been a very expensive month here so far, so will have to wait till payday!

In the meantime, I can start looking for the other odds and ends I will need to get the I Telex box made up - it is strange, Eurocard enclosures used to be so easy to find, but are quite a rare thing here nowadays!

Good, I-Telex is a very versatile system. Think about how many teleprinters you mght want to have, if
you would like to have an emulated one with a RS232 Interface for use with terminal programs.

It's good to take some time before choosing what to get :-)

[M1ECY]

The flexibility of an emulator will be very useful I think

I do not have a lot of space for lots of teleprinters, but I do know of one or two museums here in the UK that have many teleprinters that would look much happier actually doing something!

So, I have a shopping list, am I right in thinking I can build an I Telex in basic format, and then add more modules as my needs expand?

[M1ECY]

Sorry, another question.

Is the TW39 Special board able to drive a Teleprinter as well as the PC Emulator?

Thanks

[FredSonnenrein]

Yes it is.
In fact there are two almost independent units on the board.
One for TW39 and one with a normal RS232 interface (alternative option USB converter on board).

And for special self designed circuits there is also a prototype area on it.

[M1ECY]

Excellent, So I will need to order:

Power supply board
I Telex board
TW39 Special
Backplane (unless I build this myself to suit enclosure)

I need also to source the following:

2x10VA 12-15v AC supply (i assume two are needed to generate the high voltage needed for the teleprinter loop current?)
A suitable Eurocard housing (I have seen the one recommended, but will probably source something that is 19" rack)

FAG200 converter to run TP?

Anything else?
