Types of PC Cards
The PC Slot inside the DSC is designed to use PCMCIA2 memory cards of between 128kbyte and 2Mbyte of storage
capacity. As existing Flash memory cards have erase and re-write limitations, only SRAM memory cards are fully
supported in the current PCMCIA card software. The exception is that a full set-up (an XAL file) is stored to a Flash card
when it is formatted. The Flash card set-up can be then read at any time, but only written to by performing a complete
format again. This is useful for archive purposes as Flash cards do not batteries to run down. The DSC 280 has been tested
using Fujitsu 256k FLASH cards.
Formatting a FLASH card will also write and XAL file to the card. If a FLASH card is detected when a FORMAT is
started, the card is formatted as usual and then a single XAL file is written to the card using the current unit data. No further
SAVE operations can be performed on a FLASH card although the saved XAL file can be loaded at any time. All FLASH
cards are formatted as 256k with a single XAL file recorded on them, regardless of card memory size.

2 Check with the card manufacturer to confirm if the card can be recharged. Rechargeable cards should be left in the PC Slot of a DSC for a few hours to
recharge. Battery life for a rechargeable card when not plugged into a unit is expected to be around one year; this should be checked with the card
supplier.
