As shown in the pictures above, IBM terminal keyboard has a pin called "PE" on the 7th. Where should I connect this one to? :shock:
In addition, in order to complete this converter, is everything I have to do is the following?:

1. Solder/Connect/Wire RJ45's 3, 4, 5, 6, 7 (pins) to teensy++'s Vcc, PD0, PD1, GND, [?]
2. Install hex in teensy++
3. Done :!:

I would be grateful if someone can confirm myself if they are correct and the existence of the PE pin! :roll:

p.s) I am sorry if I am lacking out of some informations, since I still have no clear thoughts on these circuit works :cry:

On my M122-conversions I never connected the PE pin.

PE is likely protective earth and not necessary to wire up to a controller board.
