  1. EPICS GPIB Interface using HP LAN Box Related Web Page: http://www.slac.stanford.edu/grp/cd/soft/epics/gpib.html EPICS Collaboration Mtg Nov 14-16, 2000

  2. Topics • Requirements • Design • Design Notes • Replacement for Non-EPICS System? EPICS Collaboration Mtg Nov 14-16, 2000

  3. Requirements • Collect Waveforms after an RF Fault • Write to File and Analyze using MatLab • Use Existing HW at SLAC • Use Existing SW from BESSY and APS • Keep Project Small • Experience for Larger Future Non-EPICS Replacement Project EPICS Collaboration Mtg Nov 14-16, 2000

  5. Design Notes • No LAN box auto-reset on power cycle or ethernet disconnect/reconnect • LAN box must be available on IOC boot • No sharing LAN box with multiple IOCs • PV STAT could be more explicit on failure (ie, use TIMEOUT or COMM) EPICS Collaboration Mtg Nov 14-16, 2000
