NOTE 1: Changing the modulator type of an Orion 5850 Outdoor Unit may take up to
30 seconds. During this period, the link will not be available. Changing the OU
modulator type does not support Auto Recovery thus; the modulator type of the remote
station must be changed before the modulator type of the local station is changed.
2.2.2 RF Power Output Options
The Outdoor Unit is designed for use in countries that have adopted FCC standards.
It is possible to adjust the output power on the OU using the supplied NMS software or
a SNMP Management application. The FCC standards for the MDR2400 unit require
a limited output power as stated on page 2, U.S. only.
NOTE 1 The firmware on the Orion and MDR type OUs will not accept power level
settings that fall outside the FCC compliant levels.
2.2.3 MDR2400, MDR5800 and Orion 5850 Outdoor Units
The Outdoor Units transmit and receive RF signals through a diplexer interfaced via
an RF cable to an external antenna. The unit has a type-N connector for connection
to the RF cable used between the OU and the antenna.
The Outdoor Unit houses the following main parts:
c. Transmit/Receive Modules
d. Baseband Modulator/Demodulator Circuitry
e. Microcontroller/Framing & Buffering Circuitry
f. Power Amplifier
g. Diplexer
