8-Position Jumper: 8-position jumper arrangement that uniquely identifies up to eight NE872 remote
distribution monitor and control modules. Placing no jumper, ID position 0, is an invalid configuration. The
Pulsar Plus family of controllers can address up to eight unique NE872s. Note: factory ordered systems are
generally pre-configured and will have the jumpers appropriately set. Jumpers are arranged as shown.
