§
+1 To +511 - Adding a positive channel offset will shift the received channels
to higher channel numbers.
- Example: Received channel #1 will be shifted to channel #11 by using a channel
offset of 10.
- That means that new channels are added to the data [in front of the received
data block, with DMX value 0], while any channels that now would be higher than
512 will be removed.
- Example, continued: Channels 1 to 10 are newly added, while channels 503 to
512 are removed.
§
-1 To -511 - Adding a negative channel offset will shift the received channels
to lower channel numbers.
- Example: Received channel #512 will be shifted to channel #412 by using a
channel offset of -100.
- That means that the first channels will be removed. The frame will be shorter.
- Example, continued: Channels 1 to 100 are now removed and the frame has
412 channels in total.
§
Example: Your fixture should start with DMX channel 7.
- In the ideal case, you would set its DMX start address to 7.
- If your fixture somehow is set to channel 6, you could increase its start address
by +1.
- Or you could shift the data that is sent by your device by -1 in order to change
the data from channel #7 to channel #6.
[If you cannot change the fixture's settings or you cannot reach it anymore, for
example.]
§
Please note: According to the DMX512 standard, a minimum of 21 channels will
always be sent.
§
A Channel Offset can have several advantages, such as splitting a single universe
onto multiple output ports.
- For example, your sender can only send on one universe and you wish to output
it on two ports.
On DMX 1, you would like to send the first 150 channels and on DMX 2, you
would like to send channels 151 to 300.
Then, you can set both to the same universe and set a Channel offset of 150 for
DMX 2.
