Disabling Parallel Poll Responses

Disabling Parallel Poll Responses

The PPU (Parallel Poll Unconfigure) statement gives the controller the capability of disabling the parallel poll responses of one or more devices on the bus.

The following statement disables device 5 only:

PPOLL UNCONFIGURE 705

This statement disables all devices on interface select code 8 from responding to a parallel poll:

PPOLL UNCONFIGURE 8

If no primary address is specified, all bus devices are disabled from responding to a parallel poll. If a primary address is specified, only the specified devices (which have the parallel poll configure capability) are disabled.

HP-IB Commands

The following paragraphs describe actual HP-IB commands which can be used to perform the functions of the BASIC commands shown in the previous examples.

Parallel Poll Unconfigure Command

The parallel poll unconfigure command (PPU) resets all parallel poll devices to the idle state (unable to respond to a parallel poll).

Parallel Poll Configure Command

The parallel poll configure command (PPC) causes the addressed listener to be configured according to the parallel poll enable secondary command PPE.
