Connecting accessories to the Camera
There are two 9 pin accessory ports on the Research Series of cameras. The first is labeled
“AO \SCOPE.” This is the port that provides the relay output for direct connection to many
popular telescopes’ “CCD” autoguiding port. It also supports the relay adapter box and an
adaptive optics device similar to the AO-7 which will be made for this camera in the future.
supports our AO-7 Adaptive optics device, CFW8A color filter wheel and relay adapter box.
(Note: This is not the same thing as the telescope’s RS232 port that is commonly used to point
and slew the telescope). The second accessory port on the camera is labeled I2C AUX (“I
squared C”) and is for future accessories. Be sure to keep the static safe cap over this port to
insure that you do not accidentally plug in an accessory that is intended for the AO/SCOPE
port. Plugging in the wrong accessory to the I2C port could cause damage.
More than one accessory can be connected to the accessory ports by using multiple plug
adapters provided with the accessory.
4.7. Battery
Operation
The STL-4020M, STL-1301E, STL-1001E, STL-11000M and STL-6303E can be operated off
of a 12 volt car or marine battery using a the optional 12V power cord. The camera draws
approximately 4 amps from the battery (5 amps with the Remote Guiding Head attached) so it
would not be wise to operate directly from your car battery all night without aback up battery.
We recommend a separate battery for the camera; using your vehicle's battery with the engine
running may add undesirable readout noise, and using your vehicle's battery without the
engine running may result in a long walk home in the dark!
