3-2-4 Data Carrier Usage Level Check Function
The Data Carrier’s usage level check function varies with the Data Carriers
memory
(SRAM or EEPROM). With the SRAM DC, usage level is obtained from
the
battery check function. With the EEPROM DC, the usage
level is obtained
from the number of rewriting operations (100,000 max.).
SRAM DC with Battery
Battery Check Data
Carrier battery checks are not performed
automatically
, only when the con
-
tents
of the production date area (addresses 0000 and 0001) are read. When
a
battery
check is performed, a small current is passed through the DC’
s internal
circuitry.
T
oo much power
would be consumed if a battery check was performed
automatically every time DC memory was accessed.
Use
one of the following commands to read the contents of the production date
area
and check the battery’
s production date and current status. (The
s
at the
end of each command means carriage return.)
1, 2, 3...
1. Read command: RD H/A 1/2 0000 02*s
2. Auto Read command: AR H/A 1/2 0000 02*s
3. Polling Auto Read command: PR H/A 1/2 0000 02*s
If
the end code of the response is 00, the battery is operating normally
. If the
end
code is 7B, the battery is low. The following are responses to Read and Auto
Read commands sent to a DC with a good battery:
RD 0 0 0 9 9 5 *
AR 0 0 0 9 9 5 *
