18 Getting Started Chapter 1
NOTE The interrupt priority jumper MUST be installed in position 1 when using the
E1406 command module. Level X interrupt priority should not be used
under normal operating conditions. Changing the priority level jumper is not
recommended. Do not change unless specifically instructed to do so.
Configuring the
Switch Card Wire
Jumpers
The relay switch card has thirteen factory-installed wire jumpers (see
Figures 1-1 and 1-5) that connect COM lines of banks together to form

dual 1x32 channel configurations. These wire jumpers can be changed to
reconfigure the switch card to various 8-channel or 16-channel
configurations.
NOTE It is only necessary to change the wire jumpers when reconfiguring the
switch card for groups of eight or 16 channels (from 32). DO NOT CHANGE
the wire jumper positions unless instructed to do so in the applicable
operating procedures.
