System Controller Submenu

The XVME-653/658 automatically provides slot 1 system resource functions. The sys-
tem resource functions are explained in the Universe manual. (Contact Tundra at
www.tundra.com for a .pdf version of the Universe II manual.) This function can be dis-
abled using jumper J1. Refer to Jumper Settings in Chapter 2 (p. 2-2) for more infor-
mation. System resources are VMEbus Arbiter, BERR timeout, SYSCLK, and IACK
daisy chain driver. These resources must be provided by the module installed in the sys-
tem controller slot. The status of the XVME-653/658 system resources is reported in an
uneditable field.
