When the IIB is used with a Comparator I/O Module that supports only 8
receivers, such as a CIB, bank 0 will always be used.
Figure 6 shows the configuration of the two jumper options available on the rear
of the IIB. These jumpers should be installed at system installation time with
power removed from the IIB.

Jumper E1A is located across the top 2 terminals of the 6 pin terminal block. This
jumper must normally be installed. It is only removed for factory test.
Jumper E1B is located across the left side middle and bottom terminals of the 6
pin terminal block. Set this jumper to match the needs of your operator interface
station.
The remaining 2 terminals of the block are unused.

Figure 7 - Jumper Options Description
Because most installations require the pullup voltage to be +13.8 Vdc, no jumper
is provided with the unit for the E1B jumper terminals. If you have an application
that requires the pullup voltage to be set to +5 Vdc, you can order an additional
jumper by calling CTI Products Inc. and ordering part number 27-10351.
