POWER from either the universal AC supply or 12VDC cable is plugged
into the round 6 pin DIN connector. If you wish to make a custom
power cable, the pin outs for the connector may be found in the
appendix of this manual. We recommend 16 gauge conductor for 10’ to
15’ of cable or 18 gauge conductor for less than 10’ of cable. Smaller
gauge wire will cause a voltage drop across the cable and the camera
may not work properly.
USB connection to your computer uses a standard 15’ USB cable. If
your computer must be more than 15’ from the camera we recommend
an active extension for short distances (15’ additional) or a powered USB
extended such as the Icron Ranger for longer distances. The Icron
Ranger allows USB devices to operate up to 100 meters from the host
computer.
AO/SCOPE This port supplies the relay outputs for controlling your
telescope during a guiding session. Connect the telephone style cable to
this connector by using the supplied STL-RC adapter plug. This
connector will also allow control of a future Adaptive Optics device
similar to the AO-7. The current AO-7, designed for the ST series of
cameras cannot be used on the large format cameras.
REMOTE HEAD. This miniature 15 pin connector is for attaching the
optional remote guiding head. The remote guiding head contains a
cooled TC-237H guiding CCD identical to the guiding CCD built-in the
camera. It draws its power from the main camera and is controlled by
the same software that controls the internal guider. This option allows
the use of either the internal or the remote guiding CCD for self-guiding
during long exposures. It has its own shutter for dark frames.
WATER. The camera can be operated with our without water
circulation. Simply by attaching water circulation you can maintain a
lower operating temperature in warm environments. The water
circulation helps lower the temperature of the heat exchanger located in
the back of the camera and this, in turn, makes it easier for the TE cooler
to reach lower temperatures. The water does not need to be cooled. A
water pump is optional.
I2C-AUX
This port (covered in the photos) is not currently used. It is for future expansion of accessories.
