Programming Over HP-IB

Interface Capabilities

Interface Capabilities
The interface capabilities of the HP 16500B, as defined by IEEE 488.1 are
SH1, AH1, T5, TE0, L3, LE0, SR1, RL1, PP0, DC1, DT1, C0, and E2.

Command and Data Concepts

The HP-IB has two modes of operation: command mode and data mode. The
bus is in command mode when the ATN line is true. The command mode is
used to send talk and listen addresses and various bus commands, such as a
group execute trigger (GET). The bus is in the data mode when the ATN line
is false. The data mode is used to convey device-dependent messages across
the bus. These device-dependent messages include all of the commands and
responses found in chapters 9 through 12 of this guide for the mainframe and
the respective Programmer's Guides for each module installed in the
mainframe.

Talk/Listen Addressing

By using the touchscreen fields in the System Configuration menu, the HP-IB
interface can be placed in either talk only mode, "Printer connected to
HP-IB," or in addressed talk/listen mode, "Controller connected to HP-IB."
