Note See 3-1-2 Memory Cards and 3-1-3 EM Units for details on installing and remov-
An EM Unit may be installed in the CPU Unit when the EM Area is needed to
supplement the capacity of the DM Area. The addition of an EM Unit increases
the data memory capacity of the CVM1D from 24K words (D00000 to D24575) to
up to 256K words. This EM Area memory is divided into 32K-word banks.
When EM Units are used in a duplex system, the same model of EM Unit must be
installed in both CPU Units.
EM Units are sold separately, order one of the following EM Units when required.
When mounted to the CPU, the EM Unit is backed up by the battery mounted in
the CPU. When the EM Unit is removed from the CPU Unit, a built-in capacitor
will back up the Unit’s memory for up to 10 minutes without memory loss. It takes
about 1 minute in the CPU Unit for the built-in capacitor to become fully charged.
ing the EM Unit.
Memory Cards can be used to store data or programs as files to expand the
memory storage capacity of the PC. CVM1D PCs cannot use the FILR(180),
FILW(181), FILP(182), and FLSP(183) instructions, so Memory Card files can-
not be accessed (read or written) from the program.
Files stored in the Memory Card can be read to the CPU automatically at startup.
Also, data can be backed up from the CPU to the Memory Card when the power
is turned off. These functions are controlled by settings on the CPU DIP Switch.
(See page 32 for details on DIP Switch settings.)

5. Memory Card indicator (M/C ON)
6. Protective covers
The Memory Card indicator will be lit when the power is on. The indicator will
go off and on each time that the Memory Card power switch is pressed. Be
sure to verify that the indicator is not lit before removing the Memory Card.
Do not remove the protective covers.
