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.

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.
