Using the RS-232-C Interface
RS-232-C Interface Functions
Reception Function
Allows you to make the same settings (except for on and off of the power supply and
those related to communication) as those which can be made using the keys on the front
panel. This function allows the instrument to receive a request for the output of a
generated set-up value, measured value, panel set-up information and error codes.
Transmission Function
Allows the instrument to output a generated set-up value and measured value at a
specified cycle. The panel set-up information and status byte can also be output. In
addition, error codes which occurred can be output.
Note
• During the talk-only or printer mode (when the printer is connected), only output of the generated
set-up value and measured value at a specified cycle is available.
• When using any source other than an AC power supply, the power supply to the circuit for the RS-
232-C is turned off to increase the operating time available with batteries or the like. Turn on the
power supply as necessary. (See page 37.)

WARNING
When connecting the RS-232-C cable to the connector, make
sure the power switch of the instrument is turned OFF. Connect
the RS-232-C connector to the remote instrument with the cable
before starting the RS-232-C communication.
