Table 6 - Jumper Options Description
The MON7 line conflicts with a Digitac signal. Always remove E1A when using
the CIB with a Digitac comparator.
Some Spectra-TAC comparators with the "B" version Signal Quality Module
(SQM) can be damaged when 15V is applied externally on the Disable input. For
this reason, for CIB modules shipped after January, 2003 are shipped with E1B In,
setting the input pull-up to +5 VDC.
Remove the E1B jumper if your comparator requires +15 V pull-ups.
