2-3 Memory Cards
File memory (used to store programs and other data) is attached to the CPU in
the form of Memory Cards. The portable, high-capacity Cards allow large quan-
tities of data to be handled by simply switching Memory Cards. Because
Memory Cards are not provided with the PC, they must be selected and installed
in the CPU. Three types of Memory Card are available: RAM, EPROM, and EE-
PROM. Each of these comes in various capacities. Some of the memory is used
for file management and directories.

Note 1. Batteries should be replaced before the end of their life expectancy. Refer to
the CV-series PC Installation Guide for details on battery replacement.
2. Cannot be used without an CV500-MCW Memory Card Writer.
The following commercially available memory cards can be used for all
CV500/CV1000/CV2000-CPU01-EV1
and CVM1-CPU01/CPU11/CPU21-EV2
CPUs with lot numbers in which the rightmost digit is 6 (6) or higher. The
procedures and applications for using these memory cards is exactly the same
as for the Memory Cards provided by OMRON.
• RAM Memory Cards conforming to JEIDA4.0 and of the following sizes:
64 Kbytes, 128 Kbytes, 256 Kbytes, 512 Kbytes, 1 Mbyte, and 2 Mbytes.
Note The 2-Mbyte Memory Cards cannot be used in the CV500-MCW01 Memory
Card Writer.
Memory Cards must be formatted before use. RAM and EEPROM Cards can be
formatted with the CVSS/SSS or the CV500-MCW Memory Card Writer;
EPROM Memory Cards can be formatted with the CV500-MCW Memory
Card Writer only.
Caution Memory Cards can be damaged by twisting, shock, or exposure to high temper-
ature, humidity, or direct sunlight. Handle them with care.
2-3-1 Mounting and Removing Memory Cards
Mount a Memory Card to the CPU using the following procedure.
1, 2, 3... 1. Open the cover of the Memory Card compartment.
2. If the Memory Card is RAM or EEPROM, set the write-protect switch to OFF
so that data can be written to the Card.
3. Insert the Memory Card into its compartment. In doing so, a slight resistance
will be felt as the connector on the Memory Card mates with the connector
on the CPU. Continue pushing until the Memory Card is inserted completely
into the CPU. If the Memory Card ON/OFF switch is ON, the Memory Card
indicator will light.
