Interface Capabilities

Interface Capabilities

The interface capabilities of the HP 16500C, 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 10 through 14 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 talk-only mode by connecting to the printer or in addressed talk/listen mode by connecting to the controller.

Reference

Talk-only mode must be used when you want the system to talk directly to a printer without the aid of a controller. Addressed talk/listen mode is used when the system will operate in conjunction with a controller. When the system is in the addressed talk/listen mode, the following is true:

Each device on the HP-IB resides at a particular address ranging from 0 to 30.

The active controller specifies which devices will talk and which will listen.
