About this Manual
Up until the middle of 2011, the Astro-Physics GTO Servo Motor Drive System was described in a small section toward
the end of each individual mount manual. As time has passed and more options have become available - both in terms
of input devices and in terms of the capabilities of the servo itself - it has become apparent that the GTO Servo System
should have its own manual that would apply to all Astro-Physics GTO German Equatorial Mounts, as well as the OEM
mounts that employ our servo drive. To this end, we have prepared this manual.
The first offering of this manual was made available at the beginning of the 2011 run of Mach1GTO mounts. Although
it was prepared with current and future mount production in mind, we feel that this manual is also of value to all mount
owners with GTOCP3 Servo Control Boxes. This means that all owners of AP mounts that shipped after late May of 2004
should consider this as their reference for the GTO Servo System. Owners of the earlier GTOCP1 and GTOCP2 Control
Boxes may also find much useful information in these pages, but should be a bit cautious in that not all information will
apply to the older boxes.
One of the principal advantages of using a single manual for all the GTO Servo Drives is that we will be better able to keep
it current with all the latest information. This is especially important in the world of electronics and software where change
is the rule, and time to obsolescence often seems to be measured in minutes rather than years!
We will do our best to keep the manual updated on our Web site. We expect this manual to be a constant work-inprogress, so check our Technical Support section often for the latest information.
