I am installing an HAI - Model 32A30-1 Touchscreen Hub and 2 touchscreen to my existing omni IIe with one Keypad.
Question:
Do I move the existing Keypad to the hub and install the hub controller connection to where my existing Keypad is wired to my controller?
I know the ground is important.
I just want to make sure that I am hooking this up correctly.
I believe I am supposed to hookup the A and B controller connection along with the ground to my controller places the A and B where the A and B terminals are connected to my existing Keypad and move my only Keypad to the hub. Is this correct?

OR do I add the hub leaving the Keypad wiring as is?

Thank you
