[D] Scope Port; [E] I2C-Aux Port; [F] Ethernet; [G] Power - SBIG STX Series Operating Manual

(14' additional) such as a powered USB. For longer distances the Icron Ranger
allows USB devices to operate up to 100 meters from the host computer. For long
runs we recommend using the Ethernet interface with CAT5e cable (see [F] below).

[D] SCOPE Port

This port supplies the relay outputs for controlling the guiding of your telescope.
Connect the supplied 6-conductor telephone style cable to this connector and the other
end of the cable to your telescope drive's autoguider input port. See Section 1.6 for more
information.

[E] I2C-AUX Port

This port is for attachment of accessories: SBIG filter wheels, Adaptive Optics, etc.
Accessories designed to use this port do not require separate power supplies or control
cables running to the computer.
[F ] Ethernet
This port is for controlling the camera using Ethernet instead of USB. Connect CAT5
Ethernet cable between this port and your computer's Ethernet port. See the Software
Section 2.3 for instructions of using an Ethernet interface.

[G] Power

This port accepts 13-14VDC in to power the camera and any accessories that may be
connected to the I2C port. 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.

[H] Water In / Out

The camera can be operated with or 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, but it may be for additional
efficiency. The water fittings of the STX cameras accept tubing with 1/4 inch inside
diameter.
