FOX II T/R DP 4K • Setup Guide (Continued)
If you want the FOX II DP 4K units to pass serial or IR data or control signals, such as for serial
h.
control of a projector, connect the primary device to the transmitter and the controlled device to
the receiver via the Over Fiber 5-pole captive screw connectors on both units.
For remote monitoring of the status of the Rx optical link on either the transmitter or
i.
receiver, connect a locally constructed or obtained device to the two rightmost poles
of the Alarm and Remote RS-232 5-pole captive screw connector on that unit. The
unit shorts both poles together when no light is detected.
NOTE: The transmitter port reports the status of the link from the receiver
The receiver port reports the status of the link from the transmitter.
For remote control of a unit and for loading firmware, connect a host device, such as a computer or control system, to either of the
j.
following ports on the unit to be controlled:
Configuration port — The front panel USB mini-B connector.
NOTE: Extron recommends performing firmware updates via the Configuration port only
Remote RS-232 port — The rear panel Remote RS-232 port, the 3 leftmost poles of this 5-pole captive screw connector.
The protocol for the Remote port is as follows:
9600 baud
•
1 stop bit
•
Step 3 — Throughput Connections
NOTE:
See the two fiber cable connection drawings below. You can connect the transmitter to a compatible
receiver in one of two ways:
•
One way (transmitter to receiver) only, perform step 3a.
•
Two way (transmitter to receiver and return), perform steps 3a and 3b.
Connect the fiber between the Tx port on the transmitter and the Rx port on the receiver (
a.
NOTE: Ensure that the transmitter and connected receiver are the same transmission mode,
singlemode (SM) or multimode (MM) and that you use the correct SM or MM fiber cable to connect the
devices
If you want the receiver to return serial data (such as responses from a controlled device), IR data, or returned audio
b.
to the transmitter, connect a cable between the Tx port on the receiver and Rx port on the transmitter (
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
.

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. See the contact
