Programming over RS-232-C
This section describes the interface functions and some general
concepts of the RS-232-C. The RS-232-C interface on this instrument
is Hewlett-Packard’s implementation of EIA Recommended Standard
RS-232-C, “Interface Between Data Terminal Equipment and Data
Communications Equipment Employing Serial Binary Data
Interchange.” With this interface, data is sent one bit at a time and
characters are not synchronized with preceeding or subsequent data
characters. Each character is sent as a complete entity without
relationship to other events.
IEEE488.2 Operates with IEEE 488.1 or RS-232-C
IEEE 488.2 is designed to work with IEEE 488.1 as the physical interface. When
RS-232-C is used as the physical interface, as much of IEEE 488.2 is retained as
the hardware differences will allow. Messages for IEEE 488.1, such as DCL, GET,
and END are not available.
