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 preceding or subsequent data
characters. Each character is sent as a complete entity without
relationship to other events.
IEEE 488.2 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. No IEEE 488.1 messages such as DCL, GET,
and END are available.
