LabJack U12 - Page 41

demo – Send 0 for normal operation, >0 for demo mode. Demo mode allows this function to be called without a LabJack.
active – Enables the LabJack watchdog function. If enabled, the 32-bit counter is disabled.
timeout – Timer reset value in seconds (1-715).
reset – If >0, the LabJack will reset on timeout.
activeDn – If >0, Dn will be set to stateDn upon timeout.
stateDn – Timeout state of Dn, 0=low, >0=high.
Outputs:
*idnum – Returns the local ID or –1 if no LabJack is found.
4.36 - ReadMem
Reads 4 bytes from a specified address in the LabJack’s nonvolatile memory.
Execution time for this function is 20 milliseconds or less (typically 16 milliseconds in Windows).
Declaration:
long ReadMem ( long *idnum,
long address,
long *data3,
long *data2,
long *data1,
long *data0 )
Parameter Description:
Returns: LabJack errorcodes or 0 for no error.
Inputs:
*idnum – Local ID, serial number, or -1 for first found.
address – Starting address of data to read (0-8188).
Outputs:
*idnum – Returns the local ID or –1 if no LabJack is found.
*data3 – Byte at address.
*data2 – Byte at address+1.
*data1 – Byte at address+2.
*data0 – Byte at address+3.
4.37 - WriteMem
Writes 4 bytes to the LabJack’s 8,192 byte nonvolatile memory at a specified address. The data is read back and verified after
the write. Memory 0-511 is reserved for configuration and calibration data. Memory from 512-1023 is unused by the LabJack and
available for the user (this corresponds to starting addresses from 512-1020). Memory 1024-8191 is used as a data buffer in
hardware timed AI modes (burst and stream).
Execution time for this function is 20 milliseconds or less (typically 16 milliseconds in Windows).
Declaration:
long WriteMem ( long *idnum,
long unlocked,
long address,
long data3,
long data2,
long data1,
long data0 )
Parameter Description:
Returns: LabJack errorcodes or 0 for no error.
Inputs:
*idnum – Local ID, serial number, or -1 for first found.
unlocked – If >0, addresses 0-511 are unlocked for writing.
address – Starting address for writing (0-8188).
data3 – Byte for address.
