With the 2-PI MEB installed, the flow computer will accept two pulse
inputs from customer input devices such as reed switches, slot sensors,
magnetic pick-up, and uncommitted transistor outputs. Up to four boards
may be installed in the unit.
A unique address that determines the software configuration must be set
using jumpers JP1 and JP2 for each 2-PI MEB installed. The address
jumpers are configured as shown in the table below.
