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.
j.
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
following ports on the unit to be controlled:
Configuration port
— The front panel USB mini-B connector.

Extron recommends performing firmware updates via the Configuration port

Remote RS-232 port
— The rear panel Remote RS-232 port, the 3 leftmost poles of this 5-pole captive screw connector.

NOTE:
See the two fiber cable connection drawing at right. You can connect the transmitter and 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.
a.
Connect the fiber between the Tx port on the transmitter and the Rx port on the receiver (
1
, at right).
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.
b.
If you want the receiver to return serial data (such as responses from a controlled device), IR data, or returned audio
to the transmitter, connect a cable between the Tx port on the receiver and Rx port on the transmitter (
2
).
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.
