6.3 RS-232[EIA-232] (7352A)
6.3.1 Overview
By using the RS-232 interface, setting measurement functions and parameters of this instrument and read-
ing the measured data can be remotely controlled, and the automatic measurement system can be easily
built up.
Because the interface is electrically isolated from the measurement signal system, measured values are not
affected by external devices.
The remote commands are common to the GPIB commands.
• Specifications
The 9-pin connector (DB-9 male connector) used for the RS-232 interface is located on the rear panel
of this instrument.
Up to 251 characters in one transmission can be recognized as a program code.
If a program code exceeds 251 characters, an error occurs.
If the DSR (data set ready) status is false when it is checked in this instrument, the transmit data (TxD)
output is stopped.
Data transmission restarts when DSR is true.
CAUTION: This instrument cannot use the flow control performed by the X parameter (XON/XOFF).
