Vision requires some Source switching Logics to work as expected.
Therefore the fixture must use different input sources if it has different signal inputs. These input defines which signal is active at a time.

Vison supports:

0: Vision
1: DMX
2: CRMX / WDMX
3: Artnet
4: SACN
5: GLP DOP
6: IR Remote (Fixture)
7: Manual Mode
8: Auto Mode (Automatic Source Selection with Priority)
9 – 252: Reserved
253: Wireless (2.4 GHz)
254: Wireless (Other)
255: Ethernet

Auto Mode (Automatic Source Selection)

This mode is used to automatically switch between protocols without changing the input source. This mode should behave as follow:

Priority: 1. DMX, 2.WDMX, 2: Vision App Control

Whenever a source gets active with a higher priority DMX should be used from that source and wireless radio protocols may turned off as long as this source stays active.

Idle: WDMX and Vision App Control should be active

DMX Active: WDMX and Vision sould be off. Turn off WDMX chip, Vision will automatically handle this usecase, you just have to answer with correct response in RDM CPID Vision (50:Selected Input Source, 51:Selected Input State). CPID Vision

WDMX Active: Vision sould be off. Vision will automatically handle this usecase, you just have to answer with correct response in RDM CPID Vision (50:Selected Input Source, 51:Selected Input State). CPID Vision

Vision Active: WDMX must turned off.
