This article relates to the automatic recognition of banking terminal display messages in order to sequence an automated test cycle. To do this, the normal alpha-numeric message terminal display is suppressed and a simpler 5-bit binary message substituted. The bits are represented by illuminated blocks, each at a character position on the alpha-numeric display. The positions of the 5 blocks are selected so that they are physically as far apart from each other as possible. Each of these 5 character positions used for testing has associated with it an optical sensor to generate feedback signals to the test apparatus. A time-out circuit prevents false indications arising from the off-portion of display cycles.
