The pin out for an EBY connector on a Kodak projector remote are:
MALE (Remote) 2 1 53 4
Pins 1 and 2 are closer together and generally have a dot or other mark between them on the case.
Forward is a dry contact closure between pins 2 and 5.
Reverse is a dry contact closure between pins 3 and 5.
Pins 1 and 4 are used for remote focus and varies slightly between the E2=and E3 models.
