16 bits dmx control

Postby JePiPo » Sun Sep 08, 2024 12:11 pm

Hello,

I need to create a profile for an Infinity iW-741 RDM

PAN uses address 1 for the high bit and address 3 for the low bit, TILT uses address 2 for the high bit and address 4 for the low bit ! :-(

All the other 16-bit channels in this device have standard behaviour (2 consecutive addresses).

How can I patch Pan & Tilt in 16Bits?

Thanks in advance for your reply.

Best regards

AFAIK there is no other fixture that works in this non-standard way. LXConsole does not have a way to patch that scheme unless you use a custom subindex for the least significant byte and control it separately.

Apparently GDTF allows for out of sequence bytes for 16 bit or larger resolutions. But, LXSeries does not support this. Why someone would construct a DMX protocol in that way escapes me.

The latest build of LXConsole, 6.6.1 (19609.1), allows you to set an address offset other than 1 for the low byte of a subchannel with 16 bit resolution. This will allow you to patch your fixture.

For the pan and tilt subchannels, in the Channel Setup Window's Subchannels table, select the row for the subchannel and then click the "Resolution" button below the table. For the pan and tilt subchannels of this fixture, select "16bit | coarse; ;fine". This will offset the fine portion (the low byte) of the 16bits by two dmx slots from the coarse byte.

For others reading this, by far the normal setting on subchannels with high resolution is "16bit | coarse; fine". (Most subchannels only take 1 DMX slot with the default setting of "8bit | single".)

Hello

How fast your are ! Sunday impossible and Monday it's done :-)

It's perfectly working.

I have also tried to change the offset writing in the resolution "column" 2/3 and it's also working thus I assume every offset could be possible

Thank's again for your reability.

Regards.
