8292

GPIB CONTROLLER

Complete IEEE Standard 488 Controller Function

Interface Clear (IFC) Sending Capability Allows Seizure of Bus Control and/or Initialization of the Bus

Responds to Service Requests (SRQ)

Sends Remote Enable (REN), Allowing Instruments to Switch to Remote Control

Complete Implementation of Transfer Control Protocol

Synchronous Control Seizure Prevents the Destruction of Any Data Transmission in Progress

Connects with the 8291 to Form a Complete IEEE Standard 488 Interface Talker/Listener/Controller

The 8292 GPIB Controller is a microprocessor-controlled chip designed to function with the 8291 GPIB Talker/Listener to implement the full IEEE Standard 488 controller function, including transfer control protocol. The 8292 is a pre- programmed Intel® 8041A.
