12.5.1
Procedure for transmission
(1) An input command is sent from an external device.
The full-duplex transmission system allows you to send an input command at any time
independently of the data transmit timing of the balance.
(2) Upon successful completion of an input command, the balance will send out either a normal
completion response or the data requested by the command. If the operation has not resulted
in normal completion, or if the received input command is invalid (in error), the balance will
transmit an error response.
When the balance is in normal display mode, it usually sends a response to an input command
within one second after it is received.
However, if the balance receives a tare range command when the Set Tare function is set so
that the display is reset to 0 when the balance is stabilized after the Zero/Tare key is pressed,
or if it receives an input command that takes a long time, it sends a response after the
command is completely processed.
If the balance receives an input command when you are setting a function, when it is under
span adjustment, or it is busy for other reasons, it sends a response after that operation is
completed.
1) Commands to which a response is sent back after a specified operation is executed:
•
Tare range command, span adjustment/test command
2) Commands to which a response is sent back immediately or in 1 second after they are
received:
•
Commands other than those specified in 1) above
3) Once you have sent an input command from an external device, do not send another input
command to the balance until the external device receives a response to the command
from the balance.
