[GreenKeys] Help with Seimens T1200

[Bill Henry]

Fellows, I need some help regarding the Seimens T1200.

We have a potential customer/user in Africa who says that our equipment 
must work with a Seimens T1200 Baudot teleprinter.  At this time, I do not 
know the variant of the teleprinter the customer has - or even what 
questions I should be asking.

Our contact is an Italian Systems House who tells me that a loop interface 
is required.  But there are many varieties of "loop interface" - polar, 
neutral, 20 mA, 60 mA, 80 mA, 28V, 60V, 100V, etc.  All have been used in 
Africa at one time or another and we have supported many, but not in the 
same product.

Like Teletype, Seimens had many variants of each model.  Can someone tell 
me what questions to ask and where the user might look on  the machine to 
determine which options are installed?

This is one of those deals where the stuff must be made up and transported 
to a remote site where a "demonstration" must be made.  The T1200 in 
question will not be seen until the time of the demo but we can ask 
questions in advance.  Or, maybe I can try to be prepared for all of the 
possible I/O options of a T1200?

For example,
	Is there an extended model number such as "T1200/xxxx" or some such format 
that might identify the I/O option installed?
	If so, where on the machine is the tag/placard located?
	Do you have a translation table?
	Is possible that the user can just open the cover and physically observe 
inclusion or lack of I/O options?
	ANYTHING else that will be useful?

Thanks in advance,
