If someone has questions on the protocol, please contact me (I designed and programmed all versions from 1999 on).

If all you just wish to do is send all data all the time, just use the W command.

Example:

"W 0 12 34 56\r"

W = Write to memory 0 = first channel (channel numbers are 0-0x1FF) 12 = hex data for the first channel 34 = hex data for the second channel 56 = hex data for the third channel

All 512 channels are supported. The box can do a lot more stuff internally, but doesn't have to.

You can download the manual from our Support page http://interstellar.com/support.html

A couple of questions:

• Does this device do RDM at all? I couldn't see anything in the manual besides a "coming soon". Supporting RDM would bump this device up the priority list significantly.
• Do you support a binary protocol or just ASCII commands?
• Am I able to get hold of a test unit so I can verify my code works? I'm also in the Bay Area if that helps.

From reading the manual I assume that I'll need to use the shadow presets to avoid burning out the ram.

The hardware is set up for it and RDM is planned for a future firmware release, but we haven't had much call for it.

A loaner unit is available with some restrictions (we've had loaners not returned with no payment and no code, even from a large lighting company).

If all you're doing is sending real-time data, then you're not using any presets. You would be writing directly to the output buffer.

If you wanted to do fades in the box without using the EEPROM presets, then yes, you would use one both Shadow RAM presets. Load one with the new data and fade to it. Then load any changes and fade to it again. Once the fade is done changing the preset has no effect on the data being sent since that's in the output buffer.

I'm having trouble getting Google to notify me of updates here, can't get calendar to notify me either. Feel free to cc me on questions.
