These serial port connections are used to connect your mount to your PC computer. You must provide your own cables with
a 9 pin (DB9) male connector to interface with the GTO panel. We have provided the locking posts to secure the cable firmly.
If your serial cable does not have a 9-pin connector, you can use a gender changer or adapter to convert it.
When you are controlling the position of the mount with a computer program such as DigitalSky Voice™ or TheSky™, 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. For
instance, you can give verbal commands in DigitalSky Voice while using TheSky as a planetarium program. 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 use take advantage of this feature. If you use a laptop, you
may need to purchase a PCMCIA adapter to gain an additional serial port. Socket Communications offers adapters for many
computers. Check out their web site at www.socketcom.com.
FOCUS Connector
Attach the 2.5mm phono plug connector of your JMI Motofocus or Meade 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. Alternatively, you can verbally control the focus using the Focus Mode of DigitalSky Voice software.
RETICLE Connector
If you wish to use a plug-in type guiding eyepiece with an illuminated reticle (available from several manufacturers), insert the
2.5mm phono plug into this connector for power. Reticle brightness can be adjusted with the hand control. Refer to the
section pertaining to reticle illuminator adjustment in the GTO Keypad Manual for further information.
AUTOGUIDER Connector
This connector interfaces with the RJ-11-4 modular jack of an autoguider cable, purchased separately or as part of a CCD
Imaging Camera or Autoguider. The autoguider will be functional and ready to go as soon as you plug it in. Please refer to
the appropriate manual from the manufacturer for operation of the autoguider.
We offer CABTIC (Tracking Interface Cable for SBIG ST-4 and ST-6 camera) and CAB7/8RC (Relay cable for SBIG ST-7
and ST-8 cameras). Please refer to our price list or call for further information.
+6V Connector
This 6 volt output accepts 2.5mm phono plugs. It is used primarily to power the Pentax 6x7 camera directly from the mount
with a cord sold for that purpose (our part # CORD01).
N and S Switch
Select northern (N) or southern (S) hemisphere as needed. When you slide the switch to the opposite position, the tracking
direction of the drive will reverse. The power cord must be removed and re-attached to make this work.
Prevent the Cables from Tangling
The movement of the mount across the meridian during slewing functions is calculated so that the cables will not tangle if
they are set up properly. In addition to the motor and power cables that are provided with the mount, you may have additional
cables for other accessories. These may be powered from the GTO Control Panel or from another power source. We
suggest that you position your cabling carefully to avoid a tangled mess. When your cables are set up, move the telescope
manually throughout the normal range of movement to be sure that the cables do not catch on anything and that you have
enough length. Here are a few pointers:
Accessory Cables
Accessories may include Kendrick Dew Removers, CCD cameras and autoguiders, focus motors, illuminated guiding
eyepiece reticles, power cords for the Pentax 6x7 camera, etc. As you attach each accessory, carefully assess the best
position to assure complete movement as your telescope slews from one side of the mount to the other. If an eternal power
source is used, determine the optimum location for the battery. We prefer to use tie wraps (not glamorous, but effective) or
