SDM-SIO4 User Guide
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.
PORT1-4
These four sets of values are the current port settings in the order as below:
• Baud rate setting
• Data length setting
• Stop bit setting
• Parity bit setting
• Handshake mode
• Delay time value
• Parity error count
• Framing error count
• Overrun error count
• Line break error count
• DTR handshake line status, 0=low 1=high
• RTS handshake line status, 0=low 1=high
• CTS handshake line status, 0=low 1=high
• DSR handshake line status, 0=low 1=high
• DCD handshake line status, 0=low 1=high
You should refer to the appropriate section of this manual for further specific
detail.
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.
