System Memory - DKS 1803PC Owner's Manual

3.1.3 System Memory

Prior to starting the programming of the PC programmable telephone entry system, you must know
the memory capacity and the type of the EEPROM chips that are installed in the unit. This can be
determined by inspecting the small chip that has a tag listing the memory size on it. This memory
size determines the number of residents, vendors and four-digit entry code numbers that can be
stored in the system. If the memory chips are MemPLUS chips, device (card, transmitter) codes,
relay hold time zones, security levels, and elevator control functions can be entered into the system
memory. MemPLUS chips are identified by the letters "MP" printed on the tag on the small chip. If
the tag does not indicate MP, the chips are standard chips and the system will not have advanced
feature capabilities. The table below list the valid numbers available with each memory level.

IMPORTANT!! MemPLUS (MP) chips must be installed in this system if device (card,
transmitter, PIN) codes, tracker expansion boards, or elevator control boards are used with
the system. Relay hold open time zones, security levels, and elevator control functions
require MemPLUS chips. None of these features are available if standard (non-MP) chips are
used.
