3. Insert the RDO sensor (cable first) into the center hole of
the adapter plate, on the side opposite the cable grip;
press the sensor firmly until it clicks into place.
4. Place the nut and split seal (shoulder toward the nut) over
the cable.
5. Feed the RDO cable through the cable grip. Work the split
seal into the cable grip until almost flush, then pull the
cable through to eliminate slack.
6. Partially tighten the nut on the cable
grip.
7. Apply a small amount of lubricant to
the orange o-ring inside the large opening in the adapter
plate. Insert the front (sensor) end of the TROLL 9500
through this opening, beside the RDO sensor. Align the
RDO sensor between sensor ports 1 and 2, as shown, and
the cable beside port 1.
8. To insure a good seal, press firmly until the instrument’s
sensor block surface is flush with the adapter plate
surface. When the pieces mate properly you will hear and
feel them click together.
9. Tighten the adapter plate screw with a Phillips head
screwdriver, not overly tight.
10. Align the 3-pin connector on the RDO cable harness with
the connector in port 1 or 3 of the TROLL 9500, and press
it firmly into the port.
Tip: If you need a little more cable length, loosen the
screw, slide the adapter off, and try steps 7 and 10 in
reverse (plug in the sensor first, then attach the adapter).
Lock into place by tightening the screw.
11. Tighten the nut on the cable grip completely to insure a
good seal.

The RDO sensor will function properly only when
installed in port 1 or 3. Port 1 is normally easier to
access. If installing in port 3, you may wish to remove
the port 2 sensor temporarily (if installed). Replace
the sensor o-rings if necessary.
TIPS: If the fit is tight, apply lubricant sparingly to the
TROLL 9500 body between the label and the sensor block.
To avoid damage to the temperature sensor, orient the RDO sensor
away from the temperature sensor.
Considerable force may be needed to insure a tight seal between
the RDO adapter plate and the TROLL's sensor block
