When the Protege 16 PGM Output Expander is operating in Elevator Mode the configuration switch
settings need to be set to the correct mode and address. This should be done BEFORE connecting
and powering the unit.
Always connect the PRT-RDI2 or PRT-RDE2 Reader Expanders SA and SB terminals to the NA and NB
terminals of the slave 16 PGM Output Expanders. The S+ and S- must go to a 12V power supply source as
