Just wondering whether anyone has got an XYCOM XVME-566 card working in single-ended mode with a Power PC MVME5100 under EPICS R3.14(.8.2) ? I seem to be having two problems: 1. I am puzzled why the reported raw value of my ai test record is stuck at 4095 when there is no input signal attached to the card. I have checked the numerous switch/link settings exhaustively but can't see anything obviously wrong. 2. After a WARM reboot the following error message is issued: PV: ppcdev:my_ai_record devAiXy566Se (init_record) ai_xy566_driver error On subsequent COLD reboots the card is successfully recognised. The documentation for the card refers to the need to disable the Sequence Controller Enable Bit (Bit 8) in the Control/Status Register before performing a warm reset. I can't see any support for this in the driver (although I can see support for disabling some interrupts). Many thanks for any light anyone can shed Simon Rees Isaac Newton Group of Telescopes
