GPIBENET100_RevB9 firmware revision addresses the following issues: - B.9 is required by NI-488.2 for Windows version 2.0 and the NI-488.2 for Mac OS X version 2.0 drivers. - Faster 488.1 writes for both data and command messages for data under 1024 bytes. - Implementation of iblck. See the new user manual for a description of iblck. - Complete compatibility with improved multithreaded-multiprocess behavior introduced by version 2.0 driver. - When making an ibdev call under LabVIEW 6.0.2 on Linux & Solaris, the call would return with an EARG error. This bug was fixed in Revision B8 - Calls to VISA 2.5 on Linux, Solaris, and HP-UX would also return an error code. This bug was fixed in Revision B8. See the Getting Started Manual for your GPIB-ENET/100 for more information on updating the firmware.
