What is an SFP (Small Form-Factor Pluggable Transceiver)?
A great benet of ber is the interchangeable SFP module, which allows users to
modify the maximum distance for the required transmission run. SFP Modules
are easily and inexpensively attainable.
OS Fiber Grades
OS grading for single-mode ber pertained to the clarity of the ber’s glass. OS1
may be encountered in the eld, however, it is now considered a legacy grade.
Single-mode ber for purchase today is graded as OS2.
AVPro Edge recommends using Cleerline SSF ber, which has proven to be the
strongest and safest to handle, plus the easiest to eld-terminate.
Connector
The AC-EXO-444-KIT uses a universal LC (Lucent connector) connector type, with
two included in the kit that meet the 2 km/1.25 mi distance specication.

If these suggestions do not work, enable the Test Pattern. On the Tx, the Test Pattern is accessed using the API command
line via a connected PC. Using this method, if you see a pattern, the problem exists between the source and the transmitter;
please try a different source.
Using the Setting Button:
(On Front) The setting button can be pressed in different combinations based on what
is needed. The status light on the front will flash based on the selection. The selections are in series, meaning, for
example, if you are on selection 5 (listed below), you can come back later and press it again to move you to 6, 7,
8, 1, 2, etc... Using an ink pen is best to press the button.
The SETTING BUTTON is located front of the transmitter next to the
micro USB port. The indicator light is directly next to the button.
The SETTING BUTTON area looks like this:
EDID Management:
Quick press to select EDID
1. EDID BYPASS --- LED Flashes 1 Time (Default,
from downstream device)
2. 1080P_2CH --- LED Flashes 2 Times
3. 1080P_8CH --- LED Flashes 3 Times
4. 4K60HzY420_3D_2CH --- LED Flashes 4 Times
5. 4K60HzY420_3D_8CH --- LED Flashes 5 Times
6. 4K60Hz_3D_2CH_HDR--- LED Flashes 6 Times
7. 4K60Hz_3D_8CH_HDR --- LED Flashes 7 Times
8. USER EDID --- LED Flashes 8 Times
While in the USER EDID state (8), press and hold the setting button (for 4 seconds) in order to copy the EDID
from the connected display or downstream device to the user EDID and it will apply automatically.
Why do this?
This is commonly used when there is a need for a specific, known EDID that the installer may prefer. It can also
be used if you want to bypass an EDID of an AVR or another connected device. (IE, plug the extender kit
directly into a display and COPY the EDID. Plug it back into an AVR that may not have a current/good EDID).
Scaler Setting:
While in ANY state besides the USER EDID state, press and hold the setting button (for 4 seconds) to toggle the
scaler mode.
The options are:
1. Normal Mode(ICT Mode) --- LED Flashes 1 Time
2. Down Scaler Mode (4K->2K) --- LED Flashes 2 Times
Functions & Setup
of the Transmitter:

Indicator Troubleshooting
Lights on the
Receiver:
POWER - On the front (Setting Light): (Red) the setting light doubles as the POWER indicator. `This is an indicator that the
power is connected. There are only two states for light:
Light Is On = Power supply is connected and functioning.
Light Is Off = Power supply is not connected or there is no power present. (In order to have power: check the power
supply, USP, Outlet, etc...)
H
DMI STATUS - On the back (By HDMI Port): (Red) This indicator shows that the HDMI Sink is connected. The states are:
Light Is On (Solid) = Sync w/ HDMI sink is correct and solid.
Light Is Flashing = The light flashes during the sync process. If it is flashing continuously, you may still have a
picture, but it is indicating that the Rx is correcting a BE (Bit Error) to make the picture show on the display.
Light Is Off = HDMI is not communicating - Please check the cables.
If the RED HDMI SIGNAL STATUS LIGHT is flashing or off AND you have no picture, check the following:
1. The source. Plug it directly into the display to be sure it's functioning properly.
2. Try a longer HDMI cable. Some HDMI cables do not sync well at shorter lengths.
3. If these suggestions do not work, enable the "Test Pattern" (See Below). If you see the pattern, the problem is
between the Receiver and display/sink please try a different sink input or HDMI cable.
4. Contact AVProEdge if these suggestions do not work.

RS-232 Configuration
RS-232 can be used to pass control signals bi-directionally to & from any RS-232 compatible device. This is
commonly used to route control signals in the following way:
1. Control System --> Display/Projector (ie, Power On/Off)
2. Display/Projector --> Control System (ie, Display Status, Volume Status etc...)
3. When ultra long-range serial communication is needed (think concerts, live events). Use the extender.
The unit comes with 3 pin connectors
to allow for any wire an integrator
would like.
The pin out configuration
Left=TX, Center=Ground, Right=RX
and looks like this:
This is how the cable should look. If
using the AC-CABLE-3.5-DB9F
(Female) or AC-CABLE-3.5-DB9M
(Male), the colors will be the same.
With any other cable, please follow Tx,
G, Rx as shown above.
