port on either unit via the left poles (Tx, Rx, and _ ) of the Remote RS-232/Alarm 5-pole captive screw connector on
either unit. The protocol for these ports is as follows:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no flow control
g. 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 Remote RS-232/Alarm 5-pole captive screw
connector on that unit. The unit shorts both poles together when no light is detected.
Step 3 — Throughput Connections
NOTE: See the two fiber cable connection drawings below. You can connect the transmitter and one or more receivers
in one of three ways:
• One way (transmitter to receiver) only, perform step 3a.
• Two way (transmitter to receiver and return), perform steps 3a and 3b.
• One way (transmitter to receiver) with daisy chain (receiver to receiver), perform steps 3a and 3c.
a. Connect the fiber between the Tx port on the transmitter and the Rx port on the receiver.

b. If you want the receiver to send return serial data (such as responses from a controlled device) to the transmitter,
connect a cable between the Tx port on the receiver and Rx port on the transmitter.
c. If you want a receiver to daisy-chain the optical signal to another receiver (up to 10 receivers in a daisy chain):
• Connect the receiver Tx fiber cable to Rx on another receiver.
• Set each receiver to daisy chain mode (see “ Return Link and Daisy Chain Modes ,” below).

Step 4 — PowerCage Configuration 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.
Use SIS commands issued to the connected unit to toggle between normal and daisy chain modes. Connect a PC to the
Remote RS-232 port of either unit or to the Configuration port on the PowerCage enclosure and issue the following command:
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.
