Hi Rick,

Not sure I'm following you on the pin assignments. On the DMX hardware the pin assignments are:

Pin 1 = Ground
Pin 2 = - Data Signal
Pin 3 = + Data Signal

On the RJ45 side (Lynx MR16) I'm assuming:

Pin 1 = + Data Signal
Pin 2 = - Data Signal

So maybe the problem is my cable is configured wrong?

Checking the output of the channel on the Lynx MR16 gave some interesting results:

With the software setup (Vixen --> Enttec Pro --> MR16) the voltage was stable once I stopped moving the slider (maybe a little jump once but stable)

With the hardware setup (Hardware Board --> MR16) the voltage kept on dancing around once I stopped moving the fader.

Let me know if I have the pinout configuration completely messed up - might be the answer.

Thanks!
Robb

Hi Dr. Jones,

The hardware runs off of a wall wart - DC 9V - 12V 500mA. Since the software setup (Vixen --> Enttec Pro --> MR16) works fine I assume that my power supply running the MR16 is OK.

Thanks,
Robb

See the wiki for the pin out of the cable. You are not allowed to view links. Register or Login (should give you the correct info)

I was talking about the a chip on the MR-16 controller ( 8 pin chip in a socket next to the crystal)

Just a long shot for you to try, but I had a similar situation with my lighting board. It worked fine if I did not of my controller terminated but would not work if the terminating resister was on. I know it sounds backwards. Just something that worked for me.

RJ:
If the units uses swapped DMX lines this is waht it will do. Try hooking up the lines reverse to the unit.
