Return Link and Daisy Chain Modes
The receiver can operate in one of two modes (or both modes can be disabled):
Return link mode
— The receiver outputs data on its Tx connector for return to the transmitter.
Daisy chain mode
— The receiver daisy-chains its Rx connector input through to its Tx connector output.
Use SIS commands to toggle between return disable, normal, daisy chain modes. Connect a PC to the receiver and issue the following
command:
66*0*
n#
,
where
n
=
0
= disable,
1
= enable return link (
default mode
), and
2
= daisy chain enable.
NOTES:
•
Up to 10 receivers, each in daisy chain mode, can be connected in a daisy chain to a single transmitter.
•
Daisy chain mode works with non-HDCP sources
only
.
