Power is fed into the IDU from the mains power adaptor via a standard low voltage DC
connector. The network connection is presented to the user at the IDU via an RJ45 socket.
Connection between the ODU and IDU is made using standard CAT 5 UV resistant cable. The
spare twisted pairs of the cable are used to feed power from the IDU to the ODU.
1.3.1 The Outdoor Unit (ODU)
The ODU (Figure 2) is a self-contained unit. It houses both radio and networking electronics. A
single CAT 5 cable feeds the unit. Power is fed to the unit via the brown/brown white pair
connected to pins 7 and 8 of the RJ45 plugs and sockets employed. It should be noted that this
powering arrangement is not standard Power Over Ethernet (POE). The OS-Gemini ODU
should only be deployed using the supplied OS-Gemini Indoor Unit (IDU).
