Each device is different so you will need to check the manual for the specific device in question. Basically for another device to receive data, it must have it's "System Exclusive" mode set to ON or RECEIVE. Usually that's all that's needed.
I am always amazed to see another PDC-100 floating around. They're great for storing data, though I never thought much of the sequencer part.
Hope this helps,
