Troubleshooting a DIN

[jackchaos]

Pardon the ASCII graphics below.

I've added a second DIN to my project... only 7 of the pins are needed right now.

I've attached the j2 of DIN1 to j1 of DIN2 as shown below.

I've double checked my cableing between the two (j2->j1)

None of my buttons are responding to it.

Using the scematics here as a reference: http://www.ucapps.de/mbhp/mbhp_dinx4_32buttons.pdf

I've shorted the ground pin g(vs) to pin x(d7) of j3 on the top left of DIN2 and my my app displays it as pin 63 but the other pins do not respond at all. I expected after pin 32 to show up... not 63. None of the other pins respond at all either.

I've check for shorts and breaks in the circuit and it looks fine.

Can anyone suggest a way I can troubleshoot this DIN?

P.S.

I'm running MIOS 1.9 with a custom C application.

As always, Thanks.

P.S.

I just discovered this on the WIKI:

I'll bet you probably already have done this but...

have you tried another app like the ain64_din128_dout128_v2_0 to check the DIN?

also have you tried each DIN connected on it's own to the core, to ensure both DINX4 boards are healthy?

Thanks David,

After looking at it all day and a nap and a movie, I discovered a jumper was missing on the far right of the DIN:
