Yes, the Remote Request program will look the same as the Mori's. You should have 2 DB-25 connectors on the electrical cabinet. The top one is used for communications, the bottom one is usually for indexer controllers. The same cable wiring should work.
From the Haas LIST PROG screen, cursor to the Remote Request program and hit SEND RS232. When you see RS232 DONE, hit the END key (to highlight ALL) then hit RECV RS232.
