RJ-11 Pin
Assignments
The FlexSet PEX and PEX/APA is designed so that this extra external power can be supplied
through
pins 2 and 5
on the RJ-11 line
connector.
The customer must determine the number of units to be supplied and their configuration as well
as the type of power supply to be used and its output. The power supply must provide
24 - 48 volts DC
nominal, 15 watts for each FlexSet.
When power is supplied through pins 2 and 5 on the RJ-11 connector polarity is not important
due to an internal diode bridge.
