Daisy Chain Capability
FOX 2G Rx AV receivers have a loop-out mode that allows a
signal to be passed from the receiver along a daisy chain of
to up to ten receivers, with a display device attached to each
receiver. The loop-out mode is set using RS-232 commands. For
more information, see chapter 3, "Simple Instruction Set (SIS)
Commands"
.
All receivers in the daisy chain must be compatible, i.e. they
must all be SM or all be MM models, connected with the
appropriate fiber optic cable. Each receiver receives a signal
at its Rx fiber optic port and passes the signal to the next unit
through its Tx port.
N
In daisy chain mode, the Tx port is used to pass audio
and video signals to the next receiver in the daisy chain.
As a result, the Tx port is not available for bidirectional
communication and there are limitations on system
configuration with SIS commands.
N
When multiple receivers are in daisy chain mode,
RS-232 commands issued through the transmitter will
be passed to every receiver but commands issued through
a receiver will apply only to that receiver. Configuring
each receiver independently, matches each output signal
to the unique needs of the display device.
