3.1.7Jumpers B17...B19 Setting Interrupt Level

The VMOD-2 user can set the three jumpers B17, B18 and B19 to use any IRQ level from 1 to

7 as appropriate to his VMEbus systems application. When all three jumpers are set the IRQ

from the VMOD-2 is disabled.I

3.1.8Jumper B20 Enable/Disable "Local" Reset Input

The VMOD-2 user can take advantage of an external signal which when utilized will allow the

two piggybacks to be "reset" whenever certain external conditions occur. The external two-

wire signal is input onto pins 25 and 26 of the 50-way external interface, where the wiring and

use of these two lines are as described in section 2.3.

Note.

Jumper B20 must be set to either 1-2 or 1-3. B20 left open is not allowed.

If this jumper is left totally open (neither pin connected to pin 1) the logic

is floating and may cause spurious resets or other unpredictable prob-

lems.
