FEATURES OF CR510
The CR510 is programmed in the same way as the CR500 and executes existing CR500 programs. The
CR510 has a clock and memory backed by an internal battery. This keeps the time and data while the
CR510 is not connected to external power.
GENERAL
POWER UP
When primary power is applied to the CR510, it
tests the FLASH memory and loads the current
program to RAM. After the program compiles
successfully, the CR510 begins executing the
program. If the ring line on the 9 pin connector
is raised while the CR510 is testing memory,
there will be a 128 second delay before
compiling and running the program. This can
be used to edit or change the program before it
starts running. To raise the ring line, press any
key on the CR10KD keyboard display or call the
CR510 with the computer during the power up
sequence (i.e., while “HELLO” is displayed on
the CR10KD).
LITHIUM BATTERY
A lithium battery powers the clock and RAM
when the primary 12 VDC is not connected.
The clock is more accurate when connected to
the primary 12 VDC power supply. The lithium
battery has an expected life of four years of
continuous use. That is, the primary 12 VDC
can be disconnected for four years before the
clock stops and data are lost. The voltage of
the lithium battery is found in the 8th window of
the
∗
B mode. The voltage of a new battery is
approximately 3 volts. The lithium battery must
be replaced when its voltage falls below 2.4
VDC. (Section 14.11)
TWO FINAL STORAGE AREAS
Final Storage can be divided into two parts:
Final Storage Area 1 and Final Storage Area 2.
Final Storage Area 1 is the default storage area
and the only one used if the operator does not
specifically allocate memory to Area 2. Each
Final Storage Area can be represented as ring
memory, where the newest data writes over the
oldest data.
INTERNAL FLASH PROGRAM STORAGE
Several programs can be stored in the CR510
Flash Memory and later recalled and run using
the
∗
D Mode. (Section 1.8)
LOW VOLTAGE INDICATOR
When primary power falls below 9.6 VDC, the
CR510 stops executing its programs. The Low
Voltage Counter (
∗
B window 9) is incremented by
one each time the primary power drops below 9.6
VDC and E10 is displayed on the CR10KD. A
double dash (--) in the 9th window of the
∗
B mode
indicates that the CR510 is currently in a low
primary power mode. (Section 1.6)
CONTROL PORT COUNTERS AND INTERRUPTS
Control port 2 can be used to measure switch
closures up to 40 Hz. Control port 2 can also
be used to activate interrupt driven subroutine
98. (Sections 1.1.2, 9, Instruction 3)
TAPE
Cassette tape is not supported as a data
retrieval method with the CR510.
