ESD Warning: To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure
you are properly grounded before touching any internal AF-10 materials. Use an ESD wristband and
cord with an alligator clip attached to a good ground source
.
To adjust an AF-10 RX Board for cable length:
1.
Remove the screws at the top and bottom of the board’s faceplate.
2.
Push down on the board extractor handle and pull the board out.
3.
Set toggles (1-2-3-4) on both DIP switches (a small screwdriver or paper clip works well) to the
correct position according to the “Line Length Adjustments” table on page 129. Both DIP switches
must be set to the same value.
0 = OFF (toward the handle) and 1 = ON (toward the RJ-45 port).
4. Push the board back into position (handle will snap into place); replace screws.
Tip: Gain adjustments can also be made on the potentiometers while the board is out of the AF-10 .
