RPI components
Jumper lead to PSU 2
The RPI-8, which has only one power supply unit, has
grounding straps and plates fitted so it can be upgraded to an
RPI-16 (see illustration "RPI components").
Wiring the RPI
The maximum two-way DC loop resistance for power pairs,
including interconnections for each Base Station, is 90 ohms.
You need one or two power pairs between the RPI and the
Base Station, depending on the wire size of the power pairs
and the distance between the Base Station and the RPI.
