Overview
Broadcast Devices PCC-300, 3 Switch Combiner Controller, with SNMPv2 & Ethernet
The PCC-300 controller is designed for high-power transmitters that employ hybrid power combiners to combine two final power amplifier cabinets, achieving higher power output. These systems employ motorized coaxial or waveguide RF switches, or switchless combiners, to bypass the hybrid power combiner and put one of the two transmitter cabinets on-air by connecting directly to the antenna, while switching the other cabinet off-line for maintenance or repair, thereby minimizing off-air time. The unit supports four (4) operating modes: Combined Transmitter Cabinets A + B to Air, Transmitter Cabinet A to Air/Transmitter Cabinet B to Test Load, Transmitter Cabinet B to Air/Transmitter Cabinet A to Test Load, and Combined Transmitter Cabinets A + B to Test Load
The PCC-300 provides connections for up to three (3) motorized RF switches. All interlocks are managed by the controller to interface with any desired interlock system. The PDC-300 includes web access and SNMP v2 support. SNMPv2 support is provided via an MIB for use with remote control systems and third-party software. Broadcast Devices also provides Microsoft Windows Application software for remote control and system setup. The free software and the SNMP MIB file are available for download from the PDC-300 product page on our website. Of course, the PDC-300 has local GPIO control/status connections as well for local control/ status panels or a legacy remote-control interface.
