RS-232 Serial Interface
Use the RS-232 Port for Remote Control
This procedure is intended for those who use the 5730A Calibrator serial interface for
remote control from a terminal or computer with a serial interface.
This section describes how to set up the RS-232 interface for remote control with
protocol similar to IEEE-488. This chapter provides all details on data transmission.
The RS-232 interface is designed in accordance with EIA (Electronic Industries
Association) standard RS-232.
RS-232 Interface Specifications
The RS-232 interface is configured as DTE (Data Terminal Equipment). A null-modem
cable with two female 9-pin subminiature D connectors must be used to connect the
5730A Calibrator to other DTE (Data Terminal Equipment) such as a typical computer
serial interface. Recommended cable is a Fluke RS43.
The choices available and the defaults for all programmable interface parameters for the
Calibrator are shown in Table 5-2.
