10.5 Input Commands
Users can control the balance remotely by transmitting commands from an external device. Two
types of control commands are available:
(1) Instruction for tare subtraction
(2) Setup of output control
10.5.1 Command Transmission Method
(1) A command is transmitted to the balance from an external device. Since the data flow
(transmission and reception) is stored by a full-duplex system, commands can be transmitted
regardless of their data-transmission timing.
(2) When the balance has executed the received command, it activates a normal end response or
transmits the requested data, via the transmitting command. If the balance was unable to
execute the command or received an erroneous command, it transmits an error end response.
If the balance is working properly, it usually returns a response within a second after it receives
the transmitted command. If the balance receives a transmission while it is conducting a
procedure (such as the setup of a function or a span adjustment), it will transmit a response
when the procedure finishes.
(3) When transmitting more than one command to the balance from a remote device, wait until you
have received a confirmation on the first transmission before transmitting the next.
