Description:
The TM2020B provides a complete solution for a transparent QPSK to QAM transmodulation system. The modular TM2020B system includes universal AC input power supply, and LNB DC supply. Control and configuration is available not only locally via front panel controls, but also remotely via an RS485 or RS232 connection to a PC or modem. Up to 12 transmodulator cards are housed in a standard 19" rack-mount chassis, which may be stacked at intervals of 4U. Two TM2020B versions cover the full 54 to 860 MHz cable band.
Compatible with HITS as well as Echostar and ExpressVu! |
