B-2
AA
Advanced Status
Data Flash Block size in bytes, Total Data Flash in bytes, Largest Unused
program space in bytes, Total Program storage area in bytes, Active programs
stored (A10005008 means programs 1,5 and 8 are stored), F Number of
locations left until oldest data will be overwritten, Wrap status flag (00 = not
wrapped around, 01 = some oldest data has been erased, 11 = wrapped around
and some data erased) and Checksum (sum of all transmitted ASCII characters
since last %; wraps around at 8192 bytes).
Example:
B65536 T4194304 U131068 P131072 A00000000 F2097019 W00 C2379
is the expected response to the AA command after a SM4M has been reset.
nnnnB Move the DLP back nnnn output arrays from its current position. If it is fewer
arrays to the beginning of the file (File Mark), the DLP will be placed at the
beginning of the file. B is the same as 1B. Status is displayed following
execution of command. This command may take some time to complete.
nnnnC
Comma Delineated
ASCII Dump
Dump nnnn output arrays from the location of the DLP. The dump stops if the
next file mark or the Storage Reference Pointer is reached. ‘C’ is the same as
‘1C’. ‘0C’ means dump continuously. Status is displayed following execution
of command.
nnnnF
Binary Dump Dump nnnn locations (two bytes each) until the next File Mark from the
location of the DLP. The dump stops if the Storage Reference Pointer is
reached, followed by two bytes displaying the signature of the transmitted data.
No data conversion is made. ‘F’ is the same as ‘1F’. ‘0F’ means dump
continuously. The status is not displayed following command execution.
nnnnnnG
Go To Location nnnnnn
Use this command to position the Display Location Pointer to any location in
the Storage Module. The Status is then displayed.
OD
Go To the Oldest Data
The Display Location Pointer (DLP) is moved to the start of the oldest data in
the module. (Note: Command is letter OD, NOT ‘zero’ D).
01G
Go To Last File
This command causes the Display Location Pointer (DLP) to move to the
beginning of the current file. The status is then displayed.
08G
Go To Dump Pointer The Display Location Pointer (DLP) is advanced to the Dump Pointer position.
The Dump Pointer is set to the beginning of memory when the SM is reset. It is
advanced only by the CR10/10X (*9) Storage Module-to-Storage Module
Dump command, the ‘4H’ command, and by SMS.
09G
Go To Next File
The Display Location Pointer (DLP) is advanced to the beginning of the next
file. The DLP is advanced as the SM reads through the data until a File Mark or
the Storage Reference Pointer is encountered. For long files, the delay involved
could be noticeable. The status is displayed following command execution.
This command can be used to locate every file in the Storage Module.
09GG
Go To Next File, with
Progress indicator
As 09G, but outputs the value of the DLP every second as it is moved through
memory, as the module searches for the next file mark.
0H
Store
The Storage Module will store all data received on the Transmit Data line (TD)
until the SM is deactivated when the PE (Pin 6) and CLK/HS (Pin 7) lines go
low. External power must remain applied for at least 5ms following deactivating
PE and CLK/HS for ‘housekeeping’. The SM stores two bytes at a time. If the
total number of bytes transmitted is an odd number, a NULL character will be
added at the end of the transmission. This command is not available in
telecommunications through the CR500/510, CR10/10X or CR23X.
