The EQDir cable is a "nice to have" option for the EQmod set-up.
You can get all the benefits just using the serial upgrade cable which comes with the mount (well, you may need a serial>usb adaptor (Keyspan recommended) anyway) between the PC and the handcontroller.
Set the controller via "Utilities/" to PCDirect and Eqmod will effectively communicate between your planetarium program (I use CdC) and the mount.
Simples......
