Joop,

please help me again, I was so close but not quite!

o.k. let's go ...

1st bummer: how do I get to test "49"? When I press
TEST and then STEP, STEP, ... I can get the ocunter
up to "09" and then it rolls over to "00" :-( How
do I count up to 49?

O.K. :-)

Hmm, ffd-ing to where you describe the board:

> The servo control board is the third  board if you start 

> counting from the left. The first is called write driver 

> module, the second read amplifier and the third servo control.


and this is talking only of the first (left) set of modules.
There is another set of three boards to the right. Right?

O.K. I took out the left 3-pack and found a lonely jumper
on the third board from the left (i.e., the right-most
board in this triple.)

Now, what is the "1-2" position? The Jumper sits there
like this

top


     [*] A
     [*] B
      *  C


bottom

and there are no labels 1, 2, or 3. So, I don't know which
is 1, 2 and 3.

But no matter where I put it, I can never dial test number
49.

The other question I had is how to use the terminal connection?
I tried plugging in a terminal with null-modem, with and without
modem control various baud rates but never did I see or cause
anything to happen on this terminal line. How is that used?
Is it needed to go to test 49?

O.K. and mine does not show that number. So there is definitely
something wrong with it.

yes, I want that, but how?

 
> Return the jumper to the original position


which would be 2-3, but where is that? The upper or lower
position?

Thank you so much for your help,
-Gunther
