Astroart Forum

Hi all, I'd like to share my experience concerning the automated remote control of a spectrograph by means of an AA script. May be there are few people interested in spectroscopy (and specific Lhires III model) but the argument can also be extended to other electronic devices we have in observatory.

The heart of module is the USB relay card, a basic controller used to switch on/off a lot of devices from computer. Though it is an USB equipment, computers see it as a serial device and all communications are established through the COM port.

I'm not a script expert but I have realized that Astroart manage the controller in a very easy way using a couple of commands: Serial.Connect() and Serial.Send (). For example, with controller in COM3, I activate the relay #1 (turn on the calibration lamp on spectrograph) with commands:
In the following page you'll find further information about hardware and software implementation (a basic configuration).

Clear sky!

Great stuff Paolo!
With your agreement I'd like to also cross post on the Astronomical spectroscopy forum.
We need to see more of this type of work - automation is the way forward!
Well done mate.

Of course, Ken! I'm glad you appreciated.
