Wondering if I can get some help on a new machine (to me)

I have a 1999 Akira Seiki with Mitsubishi Meldas 520 AMR control.

I can send and receive programs no problem.

I have a program too big for memory and would like to drip feed......that's where my problems come in.

Do any of you guys know how to drip feed on a Meldas 520 AMR?????

Any help would be great.

I goto "search" on the command menu and change device to computer and I get an error....I cange it to tape....and it is "searching" but they never communicate.

Do I have to be in "tape"?
do I have to be in "auto"?


Please please help
