ting of three jumpers B17, B18 and B19, where when all three are set the IRQ from the
VMOD-2 is disabled. See section 3.1 (jumper configuration) for detailed settings.
2.2.3 Interrupt Vector Options
The user can select between several different ways to use his VMOD-2's Interrupt Vectors as
the VMOD-2 is provided with a jumper (B1) with three different possibilities. See section 3.1
(jumper configuration) for detailed settings.
1). Vector can be generated by either or both piggybacks, if these piggybacks are intelligent
enough. Most are.
2). Vector can be generated by the VMOD-2, using preset jumper coding, where non-intelli-
gent piggybacks are being fitted. In this mode a further option to assign both piggybacks
the same vector is provided by the setting of a three-pin jumper B11.
3). Vector can be generated by the lower piggyback ("B") and derived from jumper settings
on the VMOD-2 for a non-intelligent piggyback fitted into the upper piggyback ("A") loca-
tion.
The features of some piggybacks you may wish to use on your VMOD-2 are:
Dumb = no on-piggyback vector generation ability.
