SCT2860 Digital Headend Transcoder

The R.L. Drake SCT2860 transcoder module is a professional quality, modular, digital headend
component providing QPSK or 8PSK to QAM 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.

 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 monitor-

ing 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.
