Hardy Command Numbers
Here is a list of Hardy command numbers:
• 0: READ PARAM CMD. To read a parameter, write a #0 to the command register
(register #0), and write the parameter number in the parameter ID number in registers 2
and 3, most significant word first. The parameter value may then be read from registers
4 and 5, again most significant word first. This value may be in integer or floating point
format, depending on the parameter. The status register in the reply will contain the
lower 16 bits of the system status word.
• Status word bit 0: A/D error
• Status word bit 6 (0x40): Motion status.
• Status word bit 15 (0x8000): Not Found - the requested parameter number does
not exist
• 1: ZERO CMD. Write a #1 to the command register to ZERO the gross weight. The
status register will read 0 if this command succeeds.
• Status Error code 1 (motion)
• Status Error code 2 (A/D error)
• Status Error code 3 (out of tolerance)
• 2: TARE CMD. Write a #2 to the command register to ZERO the net weight. The status
register will read 0 if this command succeeds:
• Status Error code 1 (motion)
• Status Error code 2 (A/D error)
• 4: WRITE NONVOL CMD. Write a #4 to the command register to save parameters in
non-volatile memory.
• No Error Codes
• 5: PRINT CMD: Write a #5 to the command register to send data to the Printer.
• No Error Codes
