Removing the Low-to-Guard Isolation Jumper
Isolation jumper JM1 connect the Low (L) and Guard (G) commons to each
other. To minimize errors caused by lead resistance in the low lines, you
may wish to remove the jumper. Use Figure 2-4 to locate jumper.
Selecting the Interrupt Priority
The multiplexer module generates a backplane interrupt after a channel
relay closing or opening completes. You can select seven different interrupt
priority levels for this interrupt. Level 1 is the lowest priority and Level 7 is
the highest priority. The multiplexer module’s factory setting is Level 1.
Refer to Figure 2-5 to change the interrupt priority. To change, clip and
remove two jumpers from the old priority location. Install and solder two
