R command
When a communication error has occurred due to external noise, or a parity error has
occurred due to transmission error, the balance transmits an error code. In this case, send
the command again.
xx is error code number.
13-3. Control Using CTS and RTS
Depending on the "Ct5" parameter of "Serial interface (5if)", the balance performs as follows:
Ct5 0
Regardless of whether the balance can receive a command or not, the balance keeps the
CTS line HI. The balance outputs data regardless of the condition of the RTS line.
Ct5 1
The CTS line is kept Hi normally. When the balance can not receive the next command
(Example: while the balance is processing the last command), the balance sets the CTS line
to Lo. The balance confirms the level of the RTS line before outputting a set of data. If the
RTS level is Hi, the balance outputs data. If the RTS level is Lo, data is not output (The data
is canceled).
13-4. Settings Related to RS-232C
Concerning the RS-232C, the balance has two functions: "Data output (dout)" and "Serial
interface (5if)". Set each function as necessary.
