Help with Mesa 7I97T card Servo wiring

I need help assigning the right wires  between the Mesa 7i97t  and SG-AS50 servo drive, I read the Mesa manual for the 7I97T and have seen  a  lot examples that deals with steppers. but cant seem to find information using similar servo drives that I have  

As an example of the basic connections for  channel 0:

7I97T                    Drive
AOUT0 TB3.4        V-REF CN3.1
GND     TB3.3       GND    CN3.16
ENA0+ TB3.2       S-ON   CN3.7
ENA0-   TB3.1       24V    GND

QA0      TB1.1       PA0   CN3.10
/QA0     TB1.2       /PA0   CN3.11
QB0      TB1.4       PB0    CN3.12
/QB0     TB1.5       /PB0   CN3.13
IDX0     TB1.7       PC0    CN3.14
/IDX0    TB1.8       /PC0   CN3.15
 

It makes a lot more sense, now it uses the encoder values from the drive, your the greatest , thank you so much. I was looking for the pulse of reference and the sign of reference all this while

I have another challenge to  overcome I cant seem to get the 7I79 board to work it shows that its unsupported,  

it was a typo I had to used 7I79T I should just use 7I79, the connection  did not work , for some reason the network is interminting 

If you have a 7I97T you need to have the latest mesaflash

The LinuxCNC ISO includes  version is 3.4.9 which does
not support the 7I97T

I would like to ask how it is created for ENA0+ a
ENA0- voltage +/-10V? Mesa is powered by 5 volts. Is there a step up DC-DC module?

ENA+ and ENA-  pins are just a switch (an optocoupler transistor) intended
for enabling the servo drive (They are "on" when enabled)

The AOUT pins are the +-10V analog outputs. There is a DC-DC converter
on the card for the analog outputs.
