FOXBOX HDMI • Setup Guide

IMPORTANT:  Go to www.extron.com for the complete user guide and installation instructions before connecting the product to the power source.
This guide provides quick start instructions for an experienced installer to set up and operate the Extron FOXBOX HDMI fiber optic extenders.
CLASS 1 LASER PRODUCT, see FOXBOX HDMI User Guide atwww.extron.com
CAUTION:

• These units output continuous invisible light, which may be harmful to the eyes; use with caution. For additional safety, plug the attached dust caps into the optical transceivers when the fiber optic cable is unplugged.

Installation

Step 1 — Mounting
Turn off or disconnect all equipment power sources and mount the transmitter and receiver as required.

Step 2 — Input and Output Connections
a. Connect an HDMI video source to the transmitter HDMI connector.
b. If desired, connect an HDMI video display to the transmitter HDMI Loop-Thru connector.
c. Connect an HDMI video display to the receiver HDMI Output connector.

NOTE: Use a LockIt™ Lacing Bracket to securely fasten an HDMI cable to each device as follows

1. Plug the HDMI cable into the panel connection

2. Loosen the HDMI connection mounting screw from the panel enough to allow the LockIt lacing bracket to be placed over it. The screw does not have to be removed.

3. Place the LockIt lacing bracket on the screw and against the HDMI connector, then tighten the screw to secure the bracket. ATTENTION:
   • Do not overtighten the HDMI connector mounting screw. The shield it fastens to is very thin and can easily be stripped.

4. Loosely place the included tie wrap around the HDMI connector and the LockIt lacing bracket as shown.

5. While holding the connector securely against the lacing bracket, use pliers or similar tools to tighten the tie wrap, then remove any excess length.
   d. Connect an audio input device to the transmitter Input Audio 3.5 mm mini jack.
   e. Connect an audio device to the receiver 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.
   f. If you want the FOXBOX HDMI units to pass serial data or control signals, such as for serial control of a projector, connect the primary 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/Alarm 5-pole captive screw connectors on both units.
   g. 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:
   • 9600 baud
   • no parity
   • 8 data bits
   • 1 stop bit
   • no flow control
   h. 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.

Step 3 — Throughput Connections
NOTES:

• 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 a.
• Two way (transmitter to receiver and return), perform steps a and b.
• One way (transmitter to receiver) with daisy chain (receiver to receiver), perform steps a and c.
• HDCP compliance requires both fiber cables.

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 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 the Rx port on another receiver.
• Set each receiver to daisy chain mode. See “Return Link and
Daisy Chain Modes,” below.

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 that is closest to you.
Return Link and Daisy Chain Modes
The receiver can operate 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 to toggle between return disable, normal, daisy chain modes. Connect a PC to the receiver and issue the following command: 660n#, 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.
The audio on the captive screw output always remains active regardless of the setting of this switch.

Indications
Tx Link and Rx Link LEDs — When lit, the link is active (light is output [Tx] or received [Rx]).
NOTE: The Link LEDs indicate transmission of light only, not whether there is data encoded in the optical link.

Power LED — This LED lights to indicate that power is applied to the unit.
HDMI LED — This LED lights on both units when the transmitter detects a signal on its video input.
HDCP LED — This LED lights on both units when the input signal is HDCP encrypted.
Audio LED — This LED lights on both units when the transmitter detects a low level audio signal for a short period of time.

EDID
EDID Minder switch — Set this switch to one of the positions at right to select the source of the DDC or a specific resolution.
Position 0 — An EDID that has been captured from the display connected to the transmitter HDMI loop thru connector.

Position 1 — The DDC is selected via a serial port on the Tx only using an SIS command or the FOX Extender Control Program.
Position 2 – F — Specify a resolution. The table identifies the switch positions and the associated resolutions.
