b. Connect a balanced or unbalanced audio device to the
Output Audio captive screw connector, as shown at right.
ATTENTION:
•
For unbalanced audio, connect the sleeves to the ground contact. DO NOT connect the sleeves to the negative (-) contacts.
• Pour l'audio asymétrique, connectez les manchons au contact au sol. NE PAS connecter les manchons aux
contacts négatifs (–).
c. If you want the receiver to pass serial data or control signals, such as for serial control of a
projector, connect the primary device to the transmitter and the secondary device to the receiver via the left three poles
(Tx, Rx, and ) of the RS-232 Over Fiber/Alarm 5-pole captive screw connectors on both units.
_
d. 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.
Receiver Remote RS-232 port — Use the Remote RS-232 3-pole captive screw connector.
The protocol for both of these ports is as follows:
• RS-232
• 8 data bits
e. For remote monitoring of the status of the Rx optical link on either the transmitter or receiver, connect a locally
constructed or obtained device to the two right Alarm poles of the RS-232 Over Fiber/Alarm 5-pole captive screw
connector on that unit. The unit shorts both poles together when no light is detected.

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
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.

HDMI Audio Switch

This switch mutes (Off position) and unmutes (On position) the embedded audio output on the HDMI output connector.
The audio on the captive screw output always remains active regardless of the setting of this switch.
