EMERSON IC693PRG300 9030 HAND HELD PROG

The keypad for the HHP is a sealed type with tactile feedback, and has 42 keys, arranged in a matrix of six keys across by seven keys down. It has a two-line by 16 character LCD display screen. The HHP has a slot for a removable memory card , which provides a means for non-volatile, off-line program storage and restoration. The memory card can only be used with CPU numbers 311 through 341. CPU numbers 350 and above do not support either the HHP or the memory card. The memory card plugs into a connector accessed through a slot on the lower right side of the HHP (see previous figure). The HHP functionality is basically divided into four modes of operation which are selected through a key sequence on the keypad. These modes are: program mode, protection mode, data mode, and configuration mode.
