FB3 Inverting X, How?

[norty303]

I know its a little old now but as Jimbo asked I should probably reply.

I got 3 DB25 jumper boxes and made up one with 1+14 switched (X inverted) one with 2+15 switched (Y inverted) and one with both switched (X+Y inverted) I can then use whichever one is appropriate to the situation and it was cheaper than building a multiway DB25 switch box (About £10)

EDit:
Ok, that didn't work, although that was the advice given in my thread on the same subject...

AS far as i can make out, the FB3 connector is wired:

X sig to 1
X grnd to 14
Y sig to 2
Y grnd to 15



Edit:

Solution now realised, prompted by Jimbo! *thanks*

Look here for the opamp diagram
