Digital Headend Transcoder

• Each SCT2860 module may be easily mounted or removed from the RMT150 rack tray to provide for easy expansion or maintenance.
• Rapid programming for HITS and DISH Network transponders using factory stored preset programming configurations.
• Auto Seeking configuration for DISH Network transponders.
• High output power of +40 dBmV which may be locally or remotely monitored and adjusted.
• Remote control functions with monitoring allows changes and activation of "hot" standby units. Controlled over a local area network or the Internet with the addition of the optional SCTeci ethernet controller interface
• LCD for monitoring and setup from the PS151 power supply. Displays QPSK or 8PSK S/N , data rate, output level in dBmV, and other operational data.
• Operates in DVB or DigiCipher® II modes.
• QAM output may be programmed in 16, 32, 64, 128, or 256 QAM modes.
• High MER ensures a low bit error rate.
• Can be used with standard or stacked LNB installations.
• Forced air cooling in the RMT150 rack mount tray allows for cool operation even when mounted adjacent to other components. Fans are easily maintained from the front panel.
• CW output test mode available.

PRODUCT DESCRIPTION

The R.L. Drake SCT2860 transcoder module is a professional quality, modular, digital headend component providing QPSK or 8PSK to  AM transmodulation and RF upconversion functions in a single module. It receives a wide bandwidth QPSK/8PSK input signal from a satellite  transponder, demodulates the digital signal, and resends the  recovered MPEG2 digital transport stream through the cable system via a much narrower bandwidth QAM modulated signal. The end user normally utilizes a set top decoder authorizing the programming to be received.

The SCT2860 transcoder module populates the RMT150 rack tray which holds up to ten transcoders. This modular approach allows the system to be expanded one transcoder at a time instead of requiring the purchase of more capacity than desired. Up to ten SCTx860  transcoders may be powered by the PS151 power supply which also mounts in the RMT150 rack tray. The PS151 power supply also serves as an RS232 communications link for the remote control of up to 70 SCT series transcoders.
