tions Board. Refer to 3-1-9 Mounting a Communications Board for the
mounting methods.
Memory Cassettes can be optionally mounted to increase memory capacity
over just the built-in RAM. There are two types of Memory Cassette available.
These are shown in the following diagram.
C200HW-ME
When an EEPROM Memory Cassette is installed in the CPU Unit, the user
memory (UM) and I/O data can be directly read and written. There is no need for
a backup power supply. The Memory Cassette can also be removed from the
CPU Unit and used for storing data.

C200HW-ME08K
C200HW-ME16K
C200HW-ME32K
C200HW-ME64K
Note The C200HW-ME64K can be used with the C200HX-CPU65-ZE/CPU85-ZE
CPU Units only. It cannot be used with other CPU Units.
With an EPROM Memory Cassette, the program is written using a PROM Writer.
The ROM is mounted to the Memory Casette and then installed in the CPU Unit.
I/O data cannot be stored.

Set the DIP switch. For an EEPROM Memory Cassette, set pin no. 1 (write pro-
tect) to either ON or OFF. Setting it to ON will protect the program in the memory
from being overwritten. Setting it to OFF will allow the program to be overwritten.
(The factory setting is OFF.)
For an EPROM Memory Cassette, set pin no. 1 (ROM Type Selector) according
to the type of ROM that is mounted.
