You can use Type I or Type II cards in the JANUS 2050 to add memory or
connect an I/O device. You cannot use Type III cards in a JANUS 2050.
Which Memory Cards Are Recommended?
You can use Type I or Type II memory cards that have up to 64MB
of memory formatted with a DOS file allocation table (FAT). There
are many types of PC memory cards available:
• ATA (PC Card AT Attached)
• EPROM (Erasable Programmable Read Only Memory)
• EEPROM (Electrically Erasable Programmable Read Only Memory)
• Flash (Nonvolatile Memory)
• OTPROM (One-Time Programmable Read Only Memory)
• ROM (Read Only Memory)
• SRAM (Static Random Access Memory)
Intermec recommends using ATA, flash, or SRAM cards in your JANUS 2050.
Choose the type of memory card that meets your data storage needs:

Type of Data Storage
ATA Use an ATA flash card to store large amounts of data (up to 64MB) that
change frequently. ATA cards retain their data without the use of a
backup battery and are available in larger memory sizes.
Flash Use a flash card to store data (1MB to 32MB) that does not change as
frequently. Flash cards retain their data without the use of a backup
battery.
SRAM Use an SRAM card to store data (up to 4MB) that changes frequently.
An SRAM card has a lithium battery to back up data for the life of the
battery.
Note: Intermec recommends ATA and SRAM cards for most data storage needs. You
should only use a flash card as a low-cost alternative. If you decide to use a flash card,
Intermec recommends flash cards that store 1MB or more of data.
Which Expansion Cards Are Recommended?
You can use expansion or input/output (I/O) cards to connect the JANUS
2050 to I/O devices. Modem cards and network cards are examples of I/O
cards.
