8.4.1 Transmission procedure of command
① Transmit command to a scale from external devise
Command transmission is free from output timing from a scale, because the
system is full duplex.
② If the command is properly received, the scale transmits acknowledgment or
the demanded data by transmission command. If the command is erroneous
or the received command is no effective, the scale transmits non-acceptance.
When the scale indicates quantity on the display properly, the response is
transmitted in 1 second after transmission of the command.
When the command is received in such operation of the scale as settings of
unit weight, judgment values, function parameters, or in calibration, the
command is done after the operation and then the response is transmitted.
③ When the command is transmitted from external devise, do not transmit next
command until the response from a scale is received.
