DMX OH2 Binding works only on 74 channels


I’ve a problem with my OH2 Dmx-Binding and Artnet. It works fiine but only chanal 1-74 are reachable. all other channels are not avalible. If I try it with an other Artnet-software, anything works fine.

This is my Dmx.things:

    Bridge dmx:artnet-bridge:a71850e5 [ mode="unicast", address=",", universe=0, refreshrate=28] {
     color  rgb    [dmxid="39/3", fadetime=1000, dimtime=10000 ]

can anyone help?
