Drake T-4X and R-4A with Digirig mobile

I recently picked up a Drake T-4X transmitter, R-4A receiver. I also picked up the MS-4 Speaker with power supply.

I am wondering if there is a way to setup a digirig with this radio to perform digital modes.

I have attached the manual image showing how the T-4X transmitter, R-4A receiver, and MS-4 Speaker with power supply are connected together.
