4- 4
WD n WDERR n WDADDR n
WD n is a count of the number of watchdog resets, WDERR is the number of the
last task that crashed and WDADDR is the address at which the crash was found.
NC 0-9
This is the number of SDM commands the datalogger sent to the SDM-SIO4 that
the SDM-SIO4 did not recognise. This counter may be incremented when the
program is first compiled in the datalogger due to the auto speed detection of the
datalogger.

hexdump
[start address] [number of bytes]
This is used by Campbell Scientific for test purposes and outputs a hex dump of
the SDM-SIO4’s internal address space. The start address and number of bytes to
dump must be in base 10, decimal integer.
errorres
This resets all error counters.
bytewr [address] [byte]
This is used by Campbell Scientific for test purposes and writes a byte to the
memory of the SDM-SIO4.
The address and bytes to write must be in base 10, decimal integer. The address
range is 0-65535 and the byte is from 0-255.
