ESD Warning: To avoid ESD (Electrostatic Discharge) damage to sensitive components, make sure
you are properly grounded before touching any internal module materials. Use an ESD wristband
and cord with an alligator clip attached to a good ground source.
To adjust an RX Module for cable length:
1.
Remove the screws on each side of the receiver (four screws total).
FIG. 85
Remove screws indicated and lift top plate up
2.
From the rear of the module, free the edge of the module's top cover from the tabs on the rear plate
and lift the edge up.
3.
Open the lid on its hinge far enough to access the DIP switches.
4.
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.
0 = OFF (toward the power jack) and 1 = ON (toward the RJ-45 port).
FIG. 86
Set toggles on both DIP switches to the same value
5. Close the lid, inserting the tabs on the module's back plate into the slots on the top cover. Insert
screws and tighten until snug.
Tip: Gain adjustments can also be made on the potentiometers while the lid is lifted off the RX
Module.
