Chapter 13 Memory Card Adapter
13.3 Memory Card
Types
The printer’s Read-Only Memory ("rom:") or Random Access
Memory ("ram:") can be supplemented by memory cards comply-
ing with the JEIDA-4 standard and with a maximum size of 2
Mbytes.
The printer must be equipped with an optional memory card
adapter inside the front lid. Such an adapter can either be bought
as a kit or be factory fi tted.
Non DOS-formatted memory cards are available in two types,
OTPROM (One-Time Programmable Read-Only Memory) or
SRAM (Static Random Access Memory), each in several sizes in
regard of memory capacity, see below.
• OTPROM cards can only be read by the Intermec Finger-
print fi rmware after being preprogrammed using for example
the Toolbox Confi guration program. Once programmed, they
cannot reprogrammed.
• SRAM cards may be used the same way as OTPROM cards.
The fi les in such a card are regarded as an integrated part of the
printer’s ROM memory and can be listed using the statement
FILES "rom:".
DOS formatted memory cards are always of SRAM-type and
can both be read from and written to, that is, they will work almost
like a fl oppy disk. Files in a DOS-formatted card are addressed
by adding "card1:" in front of the name of the fi le. The statement
FILES "card1:" lists all fi les in the currently inserted card. Unfor-
matted SRAM cards can be DOS-formatted in the printer using the
FORMAT statement.
All SRAM memory cards require internal 3V lithium batteries
(coin type) to retain their content. Note that there is no con-
sumption of battery voltage as long as the card is inserted in a
switched-on printer. A few minutes are allowed for battery replace-
ment without any loss of data. Refer to the manufacturer’s specifi -
cations.
