backplane number setting. Table 4 provides sample addresses for the first three
backplane number jumper settings.

on P3 relay board has an address of 1. When the backplane number setting is set
to 2, the first relay on P3 relay board has an address of 97.
To set the backplane number

location and backplane number setting.
