Daisy Chain Capability
FOX Rx AV receivers have a loop-out mode that allows a signal to be passed 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 (see SIS Commands on page 13).
All receivers in the daisy chain must be compatible, that is 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.
NOTES: In daisy chain mode, the Tx port passes 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 system configuration with SIS commands is
limited.
When multiple receivers are in daisy chain mode, RS-232 commands issued
through the transmitter pass to every receiver but commands issued through
a receiver apply only to that receiver. Configuring each receiver independently,
matches each output signal to the unique needs of the display device.
