Chapter 1 General Description
© National Instruments Corporation 1-3 GPIB-VXI/C User Manual
• Interface
– TNT4882C ASIC coupled with DMA
–
Full, transparent support of individual status bytes for each GPIB
address
– Buffered operation decouples GPIB and VXIbus operation
– Controller can address one VXIbus device to talk and one or more
other VXIbus devices to listen
• IEEE 488.1 capabilities
– SH1 (Source Handshake)
– AH1 (Acceptor Handshake)
– T5, TE5 (Talker, Extended Talker): multiple primary or multiple
secondary addressing
– L3, LE3 (Listener, Extended Listener): multiple primary or
multiple secondary addressing
– SR1 (Service Request)
– DC1 (Device Clear)
– DT1 (Device Trigger)
– RL0 (Remote Local)
– PP0 (Parallel Poll)
• IEEE 488.2-compatible 488-VXIbus translation
The IEEE 488.1 capabilities are supported for all VXIbus devices
associated with GPIB addresses. The IEEE 488.2 compatibility applies to
488.2-compatible VXIbus devices associated with GPIB addresses through
the GPIB-VXI/C.
Local Command Set Overview
The GPIB-VXI/C local command set supports the following types of
operations:
• System configuration and control
