MRD 3187B - User Manual
Page vii (245)
This configuration utilizes the internal backplanes independent from one another
allowing one MRD to input two independent inputs simultaneously. With this
configuration, the MRD essentially acts like two configuration 1 no decoder units in the in
the rack space of one MRD. One input per RDS can be active.
Configuration 2 “Config 2” (Single Decoder)
This configuration utilizes the internal backplanes independent from one another. This
configuration operates identical to a configuration 1 unit except for input cards placed in
RDS2 (Slots 2-2, 2-3, 2-4) cannot be decoded. A popular use of this configuration is to
place an RF card and an ASI card (i.e. 8701A and 8702) in RDS2 to provide RF input
and ASI output to act as an 8-VSB or satellite receiver. The bottom RDS may then be
used independently to decode a different independent input.
Configuration 2 “Config 2” (Dual Decoder)
This configuration utilizes the internal backplanes independent from one another
allowing one MRD to input and decode two independent inputs simultaneously. With this
configuration, the MRD essentially acts like two configuration 1 single decoder units in
the in the rack space of one decoder. One input per RDS can be active and decode
unique video simultaneously.
