For serial control of a unit, connect a host device, such as a computer, to one of the following ports on the unit to be
controlled:
Transmitter or receiver Configuration port — A 2.5 mm mini jack. A TRS RS-232 cable is included with the transmitter.

Operation
After all receivers, the transmitter, and their connected devices are powered up, the system is fully operational. If any problems are
encountered, verify that the cables are routed and connected properly and that all display devices have identical resolutions and
refresh rates. If problems persist, call the Extron S3 Sales and Technical Support Hotline at the number that is closest to you.
Return Link and Daisy Chain Modes
The receiver operates 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.
Issue the following SIS commands from a PC connected to the receiver Remote RS-232 port to toggle between return link and daisy
chain modes or to disable both modes:
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.
