Dscr Modes - Johansson 9744MC User Manual

Digital SCR Multiswitch (Ref: 9744MC, 9746MC, 9748MC)

dSCR Modes:

SCR mode:
Legacy mode:
The 974xMC can work in two modes on each output independently – SCR Mode and Legacy
Mode.
The default mode is Legacy Mode. The module will automatic switch from Legacy to SCR mode
upon the first DiSEqC command when a SCR set top box is connected. If SCR mode has been
activated, that specific output needs to be powered-off to go back to Legacy Mode.
SCR mode: status LED slow blinking green
When a compatible Set Top Box is connected and set in "SCR Mode" up to 16 User Bands can
be generated and can be tuned independent of each other to any LNB input and transponder.
The 974xMC is compatible with EN50607 and EN50494 CENELEC-standard. The set top box
sends the desired data for the LNB input and frequency selected in DiSEqC commands.
Legacy mode: status LED solid green
When a Legacy Set Top Box (non-SCR Compatible) is connected to any of the ports, the dSCR
works like a standard multiswitch allowing only one tuner to be connected to each output and
allowing the tuner to select a single band, polarity and frequency from the relevant
transponder using 13/18 V and 0/22 kHz tone switching.
