Ethernet:
The RJ45 Ethernet connector is used for networking the base station via IP protocol, a PC can use
this connector to monitor and control the base station locally or remotely.
The Reciter supports the 10/100Mbs specification (defined by IEEE802.3u) and the MDI/MDI-X
auto crossover function which means either a straight though or crossover cable can be used to
connect the base station.
There are two LEDs embedded in the RJ45 Ethernet connector, the green LED indicates that the
Ethernet link is active; the yellow LED indicates TX/RX status between the base station and the
network.
RF input:
The receiver RF input connector: 50ohm female, N type.
RF output:
The exciter RF output connector: 50ohm female SMA or Optional N type.
