Abstract: Sample group programming apparatus comprising a program indicating plug mounted on a sample conveyor and reading apparatus adjacent the conveyor. The program indicating plug includes a support member carrying a vertically disposed optical structure, and a code cylinder rotatably mounted thereon. Five circumferential rows of apertures exist on the code cylinder, one for admitting light to the optical structure and four for providing 16 separate binary coded vertical arrays. The reading apparatus comprises a light source and four light responsive elements appropriately mounted on a support structure adjacent the conveyor to read the operative array of apertures on a plug in a reading position.
