b. Connect a balanced or unbalanced stereo or mono audio
device to the Output Audio captive screw connector. See the
drawing at right.
ATTENTION: For unbalanced audio, connect the sleeves to the ground contact. DO NOT connect the sleeves to the negative
(–) contacts.
c. If you want the PowerCage FOX SR HDMI to pass serial data or control signals, such as for serial control of a
RS-232

projector, connect the master device to the transmitter and the slave device to the receiver via the left three poles
(Tx, Rx, and
_
) of the RS-232 Over Fiber 5-pole captive screw connectors on both units.
NOTE: For RS-232 responses (from the receiver to the transmitter), you must install the Receiver-Tx-to-transmitter-Rx cable in
step 2b and leave the receiver in normal configuration (see “Return Link and Daisy Chain Modes,” below).
d. For serial control of the receiver, connect a host device, such as a computer, to the Remote RS-232

port via the left poles (Tx, Rx, and
_
) of the Remote RS-232/Alarm 5-pole captive screw connector. The protocol for
these ports is as follows:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no flow control
e. For remote monitoring of the status of the Rx optical link, connect a locally

constructed or obtained device to the two right Alarm poles of the Remote RS-232/Alarm 5-pole captive screw
connector. The unit shorts both poles together when no light is detected.
Step 4 — PowerCage Conguration Port
If desired, for serial control of the transmitter and receiver, connect a host device to the PowerCage enclosure Configuration
connector via the 9-pin D to 2.5 mm mini jack TRS RS-232 cable (included with the PowerCage enclosure or available separately using
part number 70-335-01). Repeatedly press the Comm Select button until the Comm LED lights for the slot where the transmitter or
receiver is installed. The protocol for this port is as follows:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no flow control
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 & Technical Support Hotline at the number shown below 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 or to the PowerCage enclosure
Configuration 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.
HDMI Audio Switch
This switch mutes (Off position) and unmutes (On position) the embedded audio output on the HDMI output connector.
ON
OFF
The audio on the captive screw output always remains active regardless of the setting of this switch.

HDCP LED — This LED lights when the video signal is HDCP encrypted.
Audio LED — This LED lights when the receiver detects a low level audio signal for a short period of time.
