Input commands
Users can control the balance remotely by transmitting commands from an external device. Two types of control commands
are available: instruction for tare subtraction and setup of output control.
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 and 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 a confirmation on the first
transmission is received before transmitting the next.
