SERVO MOTOR DRIVE

The GTO control box contains all of the circuitry to drive the two servo motors and the logic required to circumnavigate the

sky. It will be operational and track at the sidereal rate when connected to both motors of the mount and a power source. In

order to control the movement of the mount, you will need to connect at least one of these:

•

GTO Keypad controller

•

Computer with astronomical software such as DigitalSky Voice (included) or Software Bisque'sTheSky™ (purchased

separately).

The GTO Servo Control Box is mounted directly onto the polar axes of the 1200 and 900 mounts and is a stand-alone unit

for the 400 and 600E mount. Please remember that this box contains advanced electronics and must be treated with the

same care given to other fine equipment. Support the stand-alone unit in a secure manner so that it does not fall and do not

place it in the wet grass or dust. We have provided a pouch with a handle that can be hung from a convenient knob on your

mount, tripod or pier. You can see that the unit is built to be rugged, however it is not indestructible.

Attach one end of the Extension Cable to the 10-pin receptacle labeled "Motors" on the GTO Control Panel and the other

end to the "Y" cable, which is attached to the RA and Dec motors. Lock all connectors. The Extension and "Y" cables are

included with this mount.

Place the DC power cord (included with your mount) into the phono plug outlet marked 12V on the GTO Control Panel and

lock in place. Plug the cigarette lighter plug end of the cord into your power source. The acceptable voltage range is 11.5 to

15.

Suggested power sources include: portable rechargeable battery pack, auto or marine battery, or power supply (filtered

and regulated) for 110 volts with a minimum output of 3 amps at 12V DC.

There is no on-off switch. We recommend that you plug the power cable into the servo box after the keypad controller. To

turn the unit off, simply disconnect the power cable.

Considerations for observatory installations: We suggest that you disconnect your GTO Control Box from 110V when

you are not using your mount so that if your observatory experiences a power surge or lightening strike, your mount

electronics will not be damaged. If you operate your mount remotely, you will have to leave your power cable connected

just as you do for the rest of your electronic equipment. You may want to consider surge protectors or other protective

measures to protect from voltage spikes.

This LED will remain illuminated when your power source has sufficient output to drive the motors. If the voltage falls below

10 volts, the power light will go out and the motors will stop. The keypad controller will not function properly.

If the LED turns yellow, your motors are probably overloaded due to an unbalanced load on your mount. Refer to the

troubleshooting section of the manual for the solution.

Attach the 5 pin male connector of the keypad controller and lock in place (push in the knurled ring then turn).
