Check whether the Paragon II user station that you want to connect to the KX III is implemented with version 4.6 firmware (or later). If not, upgrade it.
The Paragon II user station can be one of these:
P2-UST
P2-EUST
P2-EUST/C
See Paragon II Help for information on upgrading.
Plug a compatible DCIM-USB into the USB and video ports on the Paragon II user station.
If the system is a two- or three-tier system, ensure the Paragon II user station is connected to the base KX III device (first tier).
Connect the Paragon II user station to a KX III device via a Cat5 UTP cable up to 150 feet (45 m).
Plug one end of the cable to the DCIM's RJ-45 port and the other end to one of the channel ports on the KX III device.
If you want to have more paths to access the same Paragon II system in KX III or CC-SG, repeat Steps 1 to 3 to connect additional user stations to the KX III.
