to be sent by the DSPEC or the % response if the last record has already been sent. RE causes
the previous binary data record to be resent exactly as it was the last time. HA causes the
WRITE command to be halted and responds with a
%130131078<CR>
record.
The number of channels that are sent on a binary data record depends on the record width as
set by the SET_WIDTH command and the number of channels remaining in the window of
interest to be sent. If the record is the last record to be sent, it will contain the number of
channels remaining in the window of interest. This may or may not be the same number of
channels as the previous record(s). If the record is not the last record to be sent, it will contain
as many channels as will fit without creating a binary data record that is longer than the limit
set by the SET_WIDTH command. The following formula can be used to determine the
number of channels that will be sent on a record that isn’t the last record:
In the above formula CHANS is the integer number of channels that will be sent on the record
and WIDTH is the current record width as set by the SET_WIDTH command (maximum
value is 512 bytes).
WRITE_FILE
“aabbccddeeff”
Writes a block of data to the file which was opened with the OPEN_FILE command. Each
byte of data is encoded as a two hexadecimal character. In the example above, 5 bytes are
sent. Multiple WRITE_FILE commands can be used to send a long file to the MCB.
WRITE_FILE_FLASH
“aabbccddeeff”
Writes a block of data to be written to the flash memory beginning with the first byte in the
flash memory. The OPEN_FILE_FLASH command must be set before using this command.
Each byte of data is encoded as two hexadecimal characters. In the example above, 5 bytes
are sent. Multiple WRITE_FILE_FLASH commands are used to send the entire block of data.
