4.4.1 Transceiver

The radio transceiver is housed in an aluminum alloy case. The connectors are listed

in the following sections.

Figure 9: Transceiver

4.4.2 IF Port (Radio Control)

The transceiver IF port (female F-type connector) is for communications with the

terminal. This port is connected with the terminal through coaxial cable.

4.4.3 RF Connector

The transceiver RF port (female N-type connector) is for sending/receiving the RF

signal to/from the antenna. A short coaxial cable is provided to connect the

transceiver to the antenna.

4.4.4 Alignment Pin and Audible Signal

For basic alignment using the received signal, an alignment buzzer (intermittent tone

sweep generator) and a voltage pin is available on the ODU transceivers. The faster

the repetition rate of the buzzer displays the stronger the signal received from the

remote end.

You can also adjust for a voltage peak using a DC voltmeter connected to the

alignment voltage pin on the ODUs (if equipped). Use of either the buzzer or

alignment pin is enabled using the software interface. Use the Web interface field

General Antenna Alignment to enable and disable this feature (Refer to section 5.5:

Configure System on page 38).

4.4.5 Antenna

The same type of antenna can be used for both ends of any PTP deployment. Refer to

section 8.3: Antenna and Power Specifications on page 81 for descriptions and

specifications of available antennas
