UBI EasyCoder 501 – Technical Manual
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 fitted.
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 UBI Fingerprint
software after being preprogrammed using e.g. the UBI
Configuration program. Once programmed, they cannot
reprogrammed.
• SRAM cards may be used the same way as OTPROM cards. The
files 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, i.e. they will work almost like a
floppy disk. Files in a DOS-formatted card are addressed by adding
"card1:" in front of the name of the file. The statement
FILES
"card1:" lists all files in the currently inserted card. Unformatted
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 consumption
of battery voltage as long as the card is inserted in a switched-on
printer. A few minutes are allowed for battery replacement without
any loss of data. Refer to the manufacturer's specifications.
