to 16. Suggested power sources include: portable rechargeable battery pack, auto or marine battery, or power supply (filtered

and regulated) for 110 volts AC input with a minimum output of 5 amps at 12V DC. We highly recommend our 13.8 volt, 5

amp power supply (PS138V5A) for the Mach1GTO.

There is no on-off switch on the servo. 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 and any

other device (CCD camera, computer, etc) 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. A disconnect relay to remove power from both

the 12-volt and ground wire is highly recommended in this situation.

POWER Indicator Light

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

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

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

Refer to the troubleshooting section of the manual for the solution.

KEYPAD Connector

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

RS-232 Connectors

These serial port connections are used to connect your mount to your PC computer. Beginning in December 2008, we began

providing a 15’ straight-through (non-crossing) serial cable with a 9-pin (DB9) male connector to interface with the GTO

Control Panel. The panel is equipped with the locking posts to secure the cable firmly onto the control box. If you purchase

a serial cable that does not have a 9-pin connector, you can use a gender changer or adapter to convert it. Please note:

the use of “crossing,” “reversing,” “null,” or “null modem” cables is a frequent source of failure and frustration. Make sure

that your serial cable is wired straight-through!

When you are controlling the position of the mount with a computer program such as PulseGuide™, Software Bisque’s

TheSky™, or Imaginova’s Starry Night™, the microprocessor chip located in the servo drive box will send continual RA and

Dec. coordinate data via the cable connections to your computer. When you use the software to give instruction to slew to a

new object, the commands (RA and Dec. coordinates) are sent to the mount.

We provide two serial port connections on the mount so that you can use two software programs simultaneously (in addition

to any auto-guider software that may be sending signals to the mount through the Auto-guider Connector). For instance, you

can use PulseGuide for advanced mount control, while using TheSky as a planetarium program. The telescope control

functions of TheSky are more limited so using both in a remote application is advantageous. Since the mount will update the

RA and Dec coordinates simultaneously, both programs are continually updated with the data from the mount. You can

watch the screen display of TheSky to see where your telescope is pointing as it slews. This is most effective if you have a

reasonably fast computer with plenty of RAM. If you try this with a 100MHz processor and only 32 MB of RAM, the response

time will be slow since both programs must be continuously updated with position data.

You must have two serial ports available on your computer to take advantage of this feature. If you use a laptop or a newer

desktop computer, you may need to purchase a USB to Serial Adapter. Starting in the spring of 2008, Astro-Physics began

offering single port and four port units made by Keyspan™ that we have found to work quite well on our own equipment.

The serial ports on the GTOCP3 control box will even allow remote operation of your mount, a handy feature for catching

those winter pretties from the warmth of the house. We have tested setups using an Ethernet based USB Server (also from

Keyspan) coupled to the four port Keyspan USB to Serial Converter. The USB Server provided four USB ports, one of

which was used by the four port USB to Serial Adapter, leaving 3 available USB and four available Serial ports at the mount.

The computer was connected to everything via a single RJ45 Ethernet cable. For a more detailed discussion, go to our

website:

www.astro-physics.com. We also recommend that you go to the Yahoo ap-gto user’s group (access it through our

website) and type “pcmcia” “serial” or “usb” into the search box. Also, be sure to keep an eye on the “What’s New?” pages

of the website for further developments in this area.

FOCUS Connector

Attach the 3.5mm phono plug connector of your JMI Motofocus or other electric focuser (optional accessories) here. Refer to

the section regarding focus adjustment in the GTO Keypad Manual for instructions on using the keypad controller to adjust

focus.
