Specifications

2.3 MEM3 AND MEM4 CARD
To operate, the KSU must be equipped with an iDCS 100 MEM3 or an iDCS MEM4 card to
hold the system software and customer database. The software is stored in EPROM chips
for the iDCS 100 MEM3 card in Flash Memory on an iDCS 100 MEM4 card. All specific
customer data is stored in non-volatile random access memory (NV-RAM). The MEM3
and MEM4 cards are both protected by a super capacitor providing up to seven days of
memory protection in the event of loss of AC power to the system.
