This question is related to the DMX splitter I'm building and shown in Prototyping a DMX splitter.
However, for testing a different question is appropriate.
I never really tested a hardware device, so be gentle please.
The intended use for the DMX splitter is to use on a music stage with my band(s). The device will be reasonably safe under my keyboard stand.
For completeness: for safety it has 5 optically and power-isolated input and four output channels, TVS's for each DMX output, a varistor and normal and temperature fuse for the main 220/240 AC, but no double enclosure, just one plastic enclosure.
I wanted to perform the following tests which might be typical for the intended usage:
- Normal behavior: power DMX splitter on (and check functionality).
- Hot-plugging input device: while DMX splitter is powered on, switch off and on DMX input device.
- Hot-plugging output devices: while DMX splitter is powered on, switch off and on DMX output device (per output).
- Removing the DMX input cable/plug and reinsert it, repeatedly.
- Removing the DMX output cable/plug and reinsert it, repeatedly.
- Power on a heavy power device on the same 220/240 V group (like a drill), repeatedly.
- Power on a 380V 3 phase device in the neighbourhood.
- Using 20 meters of cable per output (will be more than we ever need).
- Connecting 8 devices per output.
- Laying heavy power cables next/on the DMX cables (like the 380V phase cable).
Are these reasonable tests to perform or should I add more?
