Outdoor Unit (ODU)
An ODU performs the up-conversion from Intermediate Frequency (IF) of IDU (350MHz) to the
desired transmission band, and vice versa; performs the down-conversion from received
frequency band to IF frequency (140MHz) for the receiving part of the IDU. Power is supplied to
the ODU through the IF cable (used for IDU – ODU connection). The software access to ODU, its
management and configuration is possible only from the IDU. ODU management is integrated
directly in the command set of the IDU and it is an integral part of the IDU software. For an easy
primary set-up of the optimal received signal level, the ODU is fitted with the BNC connector,
where the measured DC voltage [mV] is directly proportional to the level of Received Signal
Strength (RSSI).
