These are RS-232 and may - be accessed via the front panel or the P2. The front panel connector - has both A and B serial ports on a single connector. DY-4 part number - "OBYC3ASSY901132-000 Rev-" brings these ports out to two DB-25 - female connectors. - - - The MC68681 serial ports are also accessible on the P2 connector. - DY-4 part number "OBYC3ASSY901080-004 Rev A" brings these out - to DB-9 female connectors.
