to do, but by lightly pressing the screw tips into the holes, they should “stick” enough so that you can screw them in without one or more of them (and the washers) falling out. Using a small Phillips screwdriver, tighten all four screws
(Figure 14).
16.The altitude encoder assembly is installed onto the base’s right side panel. Below the 5/8" through hole in the right panel, there are two predrilled starter holes in the inward- facing surface. Take two of the encoder wood screws sup- plied in the IntelliScope kit and push them through the two slotted holes in the bottom of the altitude encoder board. The screw heads should be on the same side as the altitude encoder’s modular jack. Now, place an alti- tude encoder nylon spacer washer on the end of each screw (Figure 15).
17.Thread the encoder wood screws into the starter holes in the right side panel with a Phillips screwdriver (Figure 15). The shaft on the altitude encoder assembly should protrude through the 5/8"
Note: The right panel does not have a white nylon bushing pressed into its 5/8" through hole like the left panel does. This is an intended design.
18.There is a pilot hole above the altitude encoder assembly; this is where the plastic bumper (found in the IntelliScope kit) that protects the altitude encoder assembly will be installed. Take the remaining encoder wood screw from the IntelliScope kit, push it through the bumper, and use a Phillips screwdriver to thread it into the pilot hole until tight (Figure 16).

Figure 15. To install the altitude encoder assembly onto the interior surface of the right side panel, insert two encoder wood screws through the slotted holes in the board. Then, add an altitude encoder nylon spacer washer onto each screw. Now, insert the shaft of the altitude encoder through the hole in the right side panel, and thread the screws into the two pilot holes using a Phillips head screwdriver.
the encoder jack in the top baseplate of the Dobsonian base. Connect the other end to the encoder connector board installed on the base’s left side panel. The azimuth encoder cable should plug into the jack on the left side of the encoder connector board (Figure 14).
20.Connect one end of the altitude encoder cable (the longer of the two flat cables in the IntelliScope kit) to the modular jack on the altitude encoder assembly. Connect the other end of the altitude encoder cable to the jack on the right side of the encoder connector board (Figure 14).
21.Use the cable clips provided with the IntelliScope kit to secure the altitude and azimuth cables neatly to the base. The clips have adhesive backing; simply peel the paper off the back of the clip and press the adhesive back to the base where you want the clip to be located.
Note: Plan your placement of the clips carefully! If you intend to disassemble the side and front panels of the base for trans- port or storage, you should first disconnect the encoder cables from one or both of their respective jacks. And you will have to remove the cables from any cable clips on base surfaces where the cable is not plugged into a jack. So we recommend using as few cable clips as possible to make things easy dur- ing disassembly and
See Figure 17 for recommended cable and cable clip place- ment. In that arrangement, only one clip is used to secure the (shorter) azimuth cable and two clips to secure the (longer) altitude cable. All three clips are affixed to the side panels. Before disassembling the side and front panels (we don’t rec- ommend disassembling the top baseplate from the ground baseplate), you would disconnect the azimuth cable from its jack in the top baseplate, and disconnect the altitude cable
