UPCOM TECHNOLOGIES General Information Safety Considerations Potential safety hazards exist unless proper precautions are observed when working with this unit. To ensure safe operation, the user must follow the information, cautions, and warnings provided in this manual as well as the warning labels placed on the unit itself. High Voltage Hazards Only qualified service personnel should service the internal electronic circuitry of the Outdoor BUC.
UPCOM TECHNOLOGIES Ports and Interfaces Prime Power Connection The Prime Power Connector is the point where the unit receives input power. The AC input can operate over a range of 90 - 260 VAC, at 47 - 63 Hz. This connector is a 3 (three) pin circular connector 3100A 14S-7P and the mating connector is supplied with the unit Pin A-C B Circuit 110/220V (90-260V) AC Ground It’s recommended that the BUC should be powered from a 180 - 260 VAC source.
UPCOM TECHNOLOGIES RF Output The RF Output is provided at a waveguide flange in the Outdoor BUCs. The C Band BUCs have CPR style grooved flange (CPR-137G). An isolator is provided at the output flange with a termination capable of handling full reflected output power. Caution should be observed here to make sure that the antenna or a suitable termination (dummy load) is connected to this port before operating the BUC.
UPCOM TECHNOLOGIES Monitors and Controls Monitor signals and Control lines are present on the M & C Connector when this option is installed. With a Microcontroller equipped system, all Monitors and Controls can also be accessed remotely by RS-232 / RS-485 to a Windows based PC; and other Alarms become available as well. Units equipped with a Redundancy option have a Microcontroller M & C installed by default. The full M & C Connector pin-out is listed here for convenience.

UPCOM TECHNOLOGIES Ground (GND) This pin is connected to the chassis, which also represents the main Ground of the unit. The installation of the BUC at the antenna and the signal and AC cables running from the BUC to the building should be properly grounded to avoid power surges that may damage the equipment. All antennas shall be grounded locally. All cable entries at the building shall be grounded at building entry. Cable entry ground shall be connected to building ground by AWG#4 copper wire.
UPCOM TECHNOLOGIES Status Display This indicator shows the general status of the Outdoor BUC – if everything is good, or if an error condition has occurred, or if the unit has been manually disabled by mute control. Also, the operating status of a Master/Slave redundant pair is reflected. Temperature Display Using the UPCOM TECHNOLOGIES Monitor and Control Software, a thermometer display with a numeric readout of the base-plate temperature of the unit in degrees Celsius is shown.
UPCOM TECHNOLOGIES Quick Start Guide Connect the low power L Band output from a modulator or a 10MHz Insertion Box to the BUC Input port. Nominal input levels are approximately -50 to 0 dBm depending on the output power level of the unit. DO NOT FEED DC VOLTAGES TO THE L BAND INPUT The BUC’s output is taken from the waveguide port (RF Out). Caution should be observed here to make sure that the antenna or a suitable termination is connected to this port before operating the BUC.
UPCOM TECHNOLOGIES General Maintenance With proper care and maintenance, your BUC will provide many years of reliable service. Please follow these maintenance guidelines so that your equipment will provide you with the maximum amount of trouble-free service. Basic Cleanliness The exterior chassis of the BUC acts as a large heatsink that must dissipate at least a few hundred Watts.
