4.1
Power cable
The power cable connects the external power supply to the power interface box.
When attaching the power cable, check the keying: the threads may engage slightly when the connector is rotated by
180° from the correct alignment. Ensure that the threading fully engages. If the power cable is correctly attached and
fully seated, the metal nut at the end of the cable will cover the gasket on the power box input.
⚠
Incorrectly seating the power connector will likely result in a short circuit, which will damage the cable and
interface box.
4.2
RX in cable (LMR-195)
This LMR-195 cable connects the LNB to the antenna RX IN port. The cable requires a right-angle N-type connector at
the antenna end to maintain the low profile of the antenna without sharp or protruding cable bends. The connector has
standard N-type connectors at teach end.
4.3
TX cable
This N-type IF cable connects the BUC in the ODU to the TX Out of the modem within the IDU. The TX cable works in the
frequency range from 1050 MHz to 1700 MHz and passes a 10 MHz reference signal to the BUC. This protocol and the
cabling is dependent on the specific modem and BUC used for each solution. Kymeta provides an N-type to F-type
adapter to connect this cable to the modem.
4.4
RX cable
This N-type IF cable sends the L-Band (950 MHz to 2150 MHz) signal from the antenna to the modem and provides DC
power for the LNB. It connects the antenna RX OUT port to the modem primary RX IN port (Rx 1). The RX cable works in
the frequency range from 950 MHz to 2150 MHz and provides power for the LNB. Kymeta provides an N-type to F-type
adapter to connect this cable to the modem.
4.5
Ethernet cable
This cable connects the data interface box to port 1 on the modem. The Ethernet port is for a standard 10/100/1000
network and is the primary monitor and control (M&C) port. It supports multiple protocols for a web server (GUI), ACU-
Modem Interface (OpenAMIP™), and an M2M (machine-to-machine) RESTful API. Installation engineers can make
multiple connections with an external switch.
