3.2 L-BAND Rx IF Connection, Type ‘N’
The Rx IF input port connector is a 50Ω Type ‘N’ female. The return
loss on these ports is typically better than 17 dB, and if the user
wishes to connect to a 75Ω system, an inexpensive ‘N’ to ‘F’ type
adapter can be used and is available as an optional accessory. While
there will be a reduction in return loss when doing this, the effect in
most systems will be imperceptible.
There may be DC voltages present on the Type ‘N’ Rx IF connector, up to a
maximum of 48 volts. An LED labeled ‘DC!’ will light to indicate this condition.
3.3 TRAFFIC GE Terrestrial Data Connection, RJ-45F
The TRAFFIC GE connector is an RJ-45 female port used for 10/100/1000 Base-T Gigabit
Ethernet data traffic. The connector pinout is as follows:
