mesa 7i96e+7i85s encoder problem

Hi everyone,
I added the 7i85s to the 7i76e and used the firmware
7i76e_7i76x1_7i85sx2d.bit

Encoders 0,1,2,3 on the 7i85s board work fine and all inputs and stepgens on the 7i76e board work too
but the encoder on the 7i76e which was previously encoder 00 now doesn't work.

Encoder 00 has now become encoder 0 on the 7i85s board
In my hal configuration I declared 5 encoders.

Some idea ?

The 7i76E's encoder is encoder 8 with that firmware (the 7I85S card 1 and 2 encoders are 0..3 and 4..7)
If you only have one 7I85S, you can use 7i76e_7i76x1_7i85sx1D firmware, in which case,
the 7I76E encoder will be encoder 4.

Thanks PCW ,
with 7i76e_7i76x1_7i85sx1D firmware
should i use the p1 or p2 connector?
Is there any problem if I leave the 7i76e_7i76x1_7i85sx2d.bit firmware with only one card?

If you have only one 7I85S, it should connect to P1

The only disadvantage of using the 7i85sx2 firmware with one
7I85S is that if you need the encoder on the 7I76E, you will
need to enable 9 encoders in the driver command line and there will be
4 wasted encoder accesses every servo thread cycle, though this
only adds a minor amount of time to the communications (about 7 usec)
