Some lights you have to enter the values, some you don't. I'm thinking that's where the issue is.
ALSO, check to see if your fixture starts at channel 0 or 1. If you start at 0, add 1(in your head) and you're done. So, if the addressing WITHIN the fixture starts at 0, and you want 157, you need to set it to 156.
Also, for the time being, honestly, screw profiles. Just address the fixture directly without a profile. This is just to test things out for now. It saves a ton of time.
Also, ensure it's all hooked up before you start MyDMX:
Connect lights, power up lights, plug in lights to MyDMX hardware, plug in hardware to computer, then run MyDMX.
Another issue might be that your DIP switches are reversed: Off is on. My Chauvet Intimidator Colors are like that. Drives me nuts!
Also, power cycle after changing addresses with DIP switches(or any other DIP switch change) and ensure your DIP switch 10 is set properly for DMX mode.
