Frequently Asked Questions
How to enter the start address - and what does the 10th DIP?!?
The 10th DIP is used to set special operating modes, e.g. stand alone modes or the switch mode for the dimmer pack.
What does Spare do with the demultiplexer, etc.?
If options can be jumpered, this is documented. Where nothing is written, nothing is implemented.
What is the power rating of resistor XY?
All resistors are 0.25W, if not otherwise stated.
What does the "X" in the parts list mean?
There are different subtypes of this part - you have the free choice of which one to use.
Can you create a parts list with order numbers of company XY for me?
Can you adapt a firmware for me or develop a new one?
Just write us an email. By the way - Donations are always appreciated...
Can you mail me PCB layouts?
The mcu cannot be accessed.
I have a different ISP programmer. Which settings are correct?
Please contact the manufacturer of the
programmer. The clock source is a high frequency crystal.
The longest startup time can be selected.
I have built the Transceiver and now the error LED flashes. What now?
This is what the error code tells you...
Even though DMX is connected, the error LED indicates "no signal present".
If a faulty cable can be ruled out and the bus is terminated, you have probably swapped D+ and D- of the DMX signal or used a crystal with the wrong frequency.
The LEDs indicate that everything is working, but nothing happens / the spots flicker randomly.
Is everything connected correctly? Did you flash the correct firmware?
The DMX Transceiver with the dimmer firmware does not work properly with my analogue dimmer pack...
Take a look at the demultiplexer ;-)
