Overview
Remote Interface Features
The 5071A‘s remote or serial port interface provides a variety of features for
such tasks as:
• Terminal operation (or terminal emulation) to allow single-line command
entry and display of instrument response.
• Remote control via computer programs or scripts to facilitate multiple
command-line tasks (with or without a modem).
• Output to a printer to provide hardcopy record of the instruments internal
operation and Event log.
• Remote communication using a modem (short-haul or telephone line) to
increase the effective distance between an operator for controlling computer
and the 5071A.
These features are discussed as they occur for hardware setup (in this section)
and later for software beginning with the Programming Overview section in this
chapter and command reference information in Chapter 5.
Serial-Port Description
The 5071A‘s serial port is a DTE device that may be connected to a printer,
terminal, computer, or modem. The available transmission protocol features are:
• RS-232C serial port supports both XON/XOFF (software) or DTR-DSR
(hardwired) pacing. Both are always enabled with the DSR input transparent
when not connected.
• Baud rate, Handshaking include 300-9600 baud, 7 or 8 data bits, 1 or 2 stop
bits, and odd, even, or no parity
•
Input End-of-Line character line-termination with CR (ASCII 13, decimal),
LF (ASCII 10, decimal), one followed by the other in either order. The
5071A‘s line termination of formatted output is <CR> and <LF>.
