18-3 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 (e.g. while the
balance is processing 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).
18-4 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.
