Showtec blinder not responding


I have a strange problem with one (and only one) of my fixtures a showtec stage blinder 2. It will not respond to DMX when connected to the outputs of my M2-GO in wing mode. It does however respond just fine if using my netron node or any other DMX controller I have.

The DMX ports on the M2-GO work just fine for ever other fixture in the rig just not this one.

Any thoughts?
