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.

NIn 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.

NWhen 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.
