Mesa 7i96 + 7i87: Error in Mode1 or Mode2

Hello,

I am playing around with a Mesa 7i96 + 7i87 (analog input). Mode0 seems to be fine but when I try to change SSerial Mode to 1 or 2 I am getting this error message during LCNC startup.

Strange, all modes work for me on at least 2.9 and 2.10
(2.8 is hard to test because of Python 2/3 issues)

Maybe some more generic issue
(the OOM error is suggestive of this)

Here's the mode 2 LinuxCNC startup info showing 6x 16 bit analog inputs:

Mhh...ok. I did more testing in Mode 0 and noticed that Port 4 - Port 7 don't show any values when I connect them to the reference voltage.

Ports 0 - 3 are constantly changing ever so slightly around 0V +/- 0.05 but Ports 4 - 7 are at 0V.

Could this be a hardware issue?

Not sure, I get all 8 input working in mode 0.

The mode errors suggest something more fundamentally wrong

Is it possible you are dropping packets?

(the sserial setup process is not very robust with regard to
dropped packets, it really should retry the entire setup
process on any error, but does not currently do this)

Also to make sure we are on the same page here, what is the 7I87 firmware version?
(16 is current)

Ok, I did update the 7i87 firmware to R16 and that fixed everything. Mode0: all channels are on and Mode1/Mode2 will now load without the error.

Thanks.

Ahh glad it was something relatively simple.

Must be a fairly old card, I think V16 came out
more that 3 years ago
