QUEST (acquiring status) command
If a QUEST command is received from the main unit's microcomputer, data for various adjustment values will be read
from memory and sent back. The return data consist of the received command as an echo back, return data, and a
checksum.
• Return data: A string of characters defined for each QUEST command is converted into ASCII codes and transmitted.
• The configuration and the data length of return data are defined for individual QUEST commands.
Example of communication:
MR / External PC
• Checksum (CS): A checksum is used for judging if any error exists in the data sent back from the panel. If an error is
detected, it is possible to resend the QUEST command from the MR / External PC to try to acquire data again.
