WP 34S - best cable layout ?

[rallyrabbit]

I am curious as well. Considering the vast amount of people that are WP-34S fans, there is general no information on the cables. I found a pinout of the board, and a pin pitch. But other than that. I can tell that the erase button is optional for sure as you can jump that with Vcc with batteries in to erase the unit.

The thing I am unclear on is whether the reset is required, and if the TX/RS are tied together or not for full/half duplex.

Would love to see more information
