Basic Telescope Setup:
1. Polar align your telescope. See the instructions that
accompany the telescope.
2. Turn "on" the #1697 Control Box. The Keypad Display (1),
Fig. 6, displays “MEADE” for several seconds as the micro-
processor does a self-diagnostic test. When the self-
diagnostic test is complete, the display shows “TELE-
SCOPE” on the top line, and “OBJECT LIBRARY” on the
lower line. The Speed Indicator LED (3), Fig. 6, next to the
“SLEW” button is illuminated.
3. At this point, the #1697 Computer Drive System is ready to
use. Select a speed at which to move the telescope by
pressing the appropriate Speed Selection Key (4), Fig 6. As
a speed is selected, the red LED next to the selected speed
lights up. Then press one of the four direction keys, (2),
Fig. 6, to move the telescope in that direction at the
selected speed.
4. With the CDS power turned on, the LXD mount can be
moved in either of two ways: (1) By loosening the R.A. and
Dec locks as described in the instruction manual supplied
with your telescope; or (2) by using the N, E, W, or S keys
(2), Fig. 6, on the Keypad.
NOTE: Telescope movement can only been seen in the SLEW
and FIND modes; CNTR (center) and GUIDE motions can only
be seen while looking through the telescope.
DO NOT attempt to adjust the LXD Equatorial Mounts with the
manual R.A. or Dec slow-motion controls when the CDS Drive
is turned on. Serious damage to the drive motor assemblies
could result.
Please note that it is possible for the telescope to hit one of the
tripod legs while manually moving the LXD Equatorial Mount
with the Keypad direction keys. The CDS software is
programmed, however to avoid hitting the tripod legs provided
the proper time, date, and site information has been entered,
and that the telescope has been properly aligned, as described
on page 7.
The quick start method described above allows you to use the
telescope, but does not make any use of the computer features
available. To utilize all the features of the #1697 Computer
Drive System, it is necessary to enter some information into the
7. Replace the Declination slow-motion knob (2), Fig. 2. Lock
in place by tightening the set screw, and replace the rubber
knurling.
8. Remove the cover plate on the opposite side of the
Declination housing, by removing the four Phillips-head
screws holding it in place.
9. Route the 16-pin ribbon cable from the Driver PCB so that
it exits the housing on the lower right-hand side. Be sure
this cable does not cover the hole in the Declination shaft,
which will block light from reaching the optional #814 Polar
Alignment Finder should one be installed.
10. Connect the 16-pin ribbon cable (2), Fig. 4, to the CDS
PCB (1), Fig. 4.
11. To position the CDS PCB into the Declination casting, first
angle the top of the PCB into the opening, allowing it to
clear the housing. Then, tilt the lower section of the CDS
into the housing. Secure the CDS in place with the four
screws.
12. Plug the RA motor coil cord into the R.A. motor port (8),
Fig. 5 on the CDS Power Panel.
13. Plug the #1697 Keypad Hand Controller into the keypad
port (7), Fig. 5, on the CDS Power Panel.
14. Plug in one of the provided power supplies: the AC Wall
Adapter Power Converter, or the DC Cigarette Lighter
Power Cord (used in an automobile's cigarette lighter
outlet). The power supply plugs into the power port (9),
Fig 5.
Installation of the #1697 CDS is now complete.

QUICK START
Although the electronics within the #1697 Computer Drive
System are advanced, the system is very straightforward to
operate—even for the beginning observer. This section is
designed as a "quick start" section for those observers anxious
to begin. Be sure to come back and read the more detailed
sections of this manual. Most of the system’s features cannot be
accessed without full knowledge of these details.
