11.3 Setting the Mode, Handshaking Method, Data Format and Baud Rate
11-8
Data Format
The RS-232-C interface of this instrument performs communications using start-stop
synchronization. In start-stop synchronization, one character is transmitted at a time.
Each character consists of a start bit, data bits, a parity bit, and a stop bit. See the
figure below.

Baud Rate
The baud rate can be selected from 75, 150, 300, 600, 1200, 2400, 4800 or 9600.
About the Terminator
Data can be received with either "CR+LF" or "LF" terminator. For transmission
terminator, you can select from "CR+LF," "LF," and "CR."
Interval
In case of the talk-only mode, this setting specifies the interval to send data.
Setting range: 00.00.00 (0 hr 0 min 0 sec) to 99.59.59 (99 hrs 59 min 59 sec)
Initial value: 00.00.00
Note
The error code 390 may appear depending on the status of this instrument. In such a case,
lower the baud rate.
