Connecting digital mode interface to acc port


I want to do true RTTY connecting my digital modes interface to the ACC port of my IC7000.
The FSK output ot the interface is open collector. May I connect this FSK output directly to pin 10 of the ACC port?
Or do I need to add a pull up resistor?

And for CW, given that the CW of the interface is open collector, may I connect it directly to the KEY port of the 7K?

I would appreciate any help much.
