INTRODUCTION
Thank you for purchasing the encoder kit which will allow you to connect
Digital Setting Circles or a computer (DSC / Computer) to your Tele Vue mount.
Gibraltar5/HD5 only: An additional Spacer Kit, product code STS-5002,
is required for installation of the azimuth encoder onto a Gibraltar5/HD5mount. Some Gibraltar5 heads have a 10x32 hole on the arm to hold theazimuth encoder and others have a smaller 8x32 hole. Both size bolts in
1½" length are provided here. The 8x32 bolt includes a washer to secure
the plastic encoder housing. Use the bolt that fits. Otherwise the kit is identi-Altitude Encoder

the mount head). Leave this altitude bearing alone.
2) Using a utility knife blade, pry the name plate off the right side altitude
bearing cover (as seen standing behind the mount head). This is the opposite
bearing from where the alignment marks are.
3) This will reveal 2 Allen key screws. Remove the screws and bearing cap
with the 5/64 Allen key.
4) Check the threaded hole in the right-side brass altitude bearing for a setscrew. If no set-screw is found, use the #8-32x3/8" provided in the parts bag.
5) Make sure the plastic shim is still in place, then slip the shaft of the Altitude

8) Chose the 1½" button head screw that's the right size for the hole in the#10-32x1½"

10) Check the upper threaded hole in the lower azimuth bearing basefor a set-screw. If no set-screw is found, use the #8-32x3/4" provided in
the parts bag.

11) Connect the azimuth lead of the Wiring Harness to the Azimuth Encoder.
12) Press the Azimuth Encoder shaft down into the hole in the center of
the azimuth bearing.

13) With the 5/64 Allen key, lock the set-screw against the az. encoder shaft.
14) Rotate the encoder so the wiring harness terminal faces the Altitude
Encoder and route the remaining terminals out the back of the Yoke, under
the cradle. (See photo , right.)
15) Slide the Azimuth Encoder Cover down between the Yoke Arms sothat the screw holes line up with the middle of the three clearance holes inthe Yoke Arms. The Azimuth Encoder Cover will fit only one way over the
Azimuth Encoder: make sure the encoder is aligned properly with the recess

in the cover before pressing it on. Do not force the cover onto the encoder;
the encoder will have a snug fit into the cover cut-out.
If it is too difficult to achieve this alignment, remove the encoder (see thesection on Removing and Reinstalling encoders), insert the encoder body

into the recess in the cover and attempt to install the encoder and cover asa unit. Again, do not force the encoder. Retighten the set screw.
If Azimuth Encoder Cover is loose between the Yoke Arms, cover the faceof the screw threads on each side of the Encoder Cover with clear tapeand test fit it. Add more layers, evenly, to each end, if necessary. When

the fit is snug, trim the excess tape and poke a hole in the tape to allow
the screws to pass through.
16a) Gibraltar5/HD5 mounts: place the spacers from the STS-5002 kit#10-32x1/2"
flat head screws

between the ends of the Delrin azimuth bar and the insides of the yokearms. Thread the 10-32x1¼” button head screws provided in the kit into
each side to hold the Azimuth Encoder. Continue with step 16c.
16b) All other mounts: thread a 10-32x½" button head screw into eachside to hold the Azimuth Encoder Cover in place. Continue with step 16c.
16c) Tighten button head screws with the 1/8 Allen key while pressing
down on the cover.
Hook a finger under one arm of the azimuth cover and pull it up (awayfrom the base plate) while tightening its round head screw. Repeat withthe other arm.
17) Connect the altitude lead of the Wiring Harness to the Altitude Encoder.

1) Remove the button head screw(s) holding the respective encoder
cover in place.
2) Loosen the respective encoder shaft set-screw.
3a) Altitude Encoder - Place the drift against the end of the encoder
shaft, as seen in the bottom photo on the prior page. Tap lightly witha hammer to dislodge the encoder3b) Azimuth Encoder - The head must be removed to stick drift intothe 3/8" hole in the middle of the underside of the Azimuth bearing.
