30 Chapter 1 Getting Started
Command line interface
Common test procedures can be accomplished using the 882’s physical controls on the
front panel, Virtual Front Panel or through the command line interface. The 882 supports
an ASCII command and query language that allows you to control the 882 interactively or
through batch processing of command files. All 882 functions are supported through this
interface. The command line interface is available through three physical interfaces:
• Serial (RS-232) interface (terminal session, such as HyperTerminal, via the serial port)
• Ethernet network interface (Telnet session or Web browser via the Ethernet port)
• GPIB (IEEE-488) interface (via the GPIB port)
The serial and Ethernet interfaces are described in this section. For information on the
GPIB interface, see Chapter 6, “Using GPIB Interface.”
Working with the serial interface
This section describes how to connect the 882 to the PC via the serial port, how to
establish a terminal session with the 882 using a terminal emulator such as
HyperTerminal, and how to change serial port settings.
To connect the 882 to the PC:
To set up the 882 to use the serial interface, connect a serial null modem cable from the
serial port of the PC to the SERIAL connector on the rear of the 882.
Establishing a terminal session with the 882
The following procedure describes how to establish a terminal session with the 882
through the serial port. For information about establishing a Telnet session over an
Ethernet LAN, see “Establishing a Telnet session with the 882” on page 33.
To establish a terminal session with the 882:
1. Open a terminal emulator, such as HyperTerminal. Configure the terminal emulator to
use the parameters set in the 882. By default, the 882’s serial port is set to 9600 baud,
8 data bits, no parity, 1 stop bit, no flow control.
2. Establish a terminal connection with the 882. Press Enter until the C:> prompt appears.
Configuring the 882’s serial port
The following procedures describe how to change the 882’s default serial port
configuration for a terminal session. You can configure the serial port through either the
front panel, Virtual Front Panel or through the command line interface.
