Connect the A, A/, B, B/, Z, Z/ signals as shown in the 7i33
documentation provided by mesa:
http://mesanet.com/pdf/motion/7i33man.pdf
Then connect the 7i33 to the 5i20 with a ribbon cable.
Then, in your hal configuration, you will use the corresponding
m5i20.<board>.enc-<channel>-* pins and parameters for the position
feedback from the motor.
http://linuxcnc.org/docs/html/hal_drivers.html#r1_5
For instance, if you connect A to ENCA0, A/ to ENCA0/, B to ENCB0/ and
so on, and connect the 7i33 to the 5i20 connector P2 on your first or
only board, then the HAL items corresponding to this encoder will be
named
m5i20.0.enc-0-*
In the sample configuration "m5i20", m5i20.0.enc-0 and m5i20.0.dac-0 are
set up to correspond to the machine's X axis.
