Data Format
The serial 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

Level returns to idle
state (dotted line) or

Baud Rate
The baud rate can be selected from 1200, 2400, 4800, and 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 output data.
Setting range: 00.00.00 (0 hr 00 min 00 sec) to 99.59.59 (99 hrs 59 min 59 sec)
Initial value: 00.00.00
When set to 00.00.00, the interval is equal to the display update rate. In addition,
when the specified interval is shorter that the display update rate, the data is output
using the display update rate.
Note
The error code 390 may appear depending on the status of this instrument. In such a case,
lower the baud rate.
