Mesa 7i96 mixed voltage field input wiring

Here is the 7I96/7I96S input circuit

Notes:

1. The quad optos are AC input type

2. The solid GND symbol is input common

 
 

1.)Hello,Is this connection of the 7i96 inputs identical / similar for the 7i95T?

2.)What is the connection diagram for MPG ENCODER INPUTS (7i95T)?

I have a problem - in the manual for the 7i95T (page 17) it says:

" MPG ENCODER INPUTS
Standard 7I95 firmware provides 4 quadrature MPG encoder inputs on isolated
inputs 0 through 7. Since the input threshold on isolated inputs is about 3V, its best to use
sinking inputs (with the input common terminal tied to +5V) with TTL output level MPGs." 

Isn't that sourcing input?

Thanx

Yes, if the input common is a + voltage, those are sourcing inputs.

( it's easy to get confused as sourcing inputs connect to a sinking drivers and vice versa )
