Result of Judgement
Result of judgement when operating the balance with the limit function (S1: one
character).
Status (S2: One Character)
2.3.5 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
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.
