12.3 Setting the Mode, Handshaking Method, Data Format and Baud Rate
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. Refer to the figure below.
Data bit
(7 or 8 bits)
1 character
Stop bit
1
1 or 2 bits

Parity bit
Even, odd or none
Start bit
Circuit idle
state
Level returns to idle
state (dotted line) or
the start bit the next

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 (0hr 0min 0sec) to 99.59.59 (99 hrs 59min 59sec)
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.
