This is the current version of keyboard interface electronics used in Honeywell's classic furniture. This interface supports both 'ABCDE' and 'QWERTY' membranes.

Since this interface brings both power and data through a single cable, it can only be used with the CE-compliant EPDGC I/O board and the newer versions of the non-CE EPDGP I/O board - the 51304854-200 and 51304854-300.

The original 5-slot power supply (51400712-100) and 10-slot power supply (51400712-200) cannot be used with this keyboard interface, since they do not furnish sufficient power to operate the keyboard.
