Title: First LE Build having problems with DMX input
Post by: pugs1501 on March 21, 2011,

I had problems installing the 485 chip to the right of RJ45 Connector. I did a continuity test on pin one and it said it was connected to pin6 and pin7 of the same chip. I was wondering if Pin1, 6, and 7 were supposed to be connected. I ran the built in test and all channels worked and the ZC led came on but the DMX LED did not and the Lynx Express Configuration Utility can not communicate to the LE, I also tried the dongle test in VIxen and I saw the dongle led lightly blinking and the LE led looked like it was slightly blinking but none of the information gets past that. Thank you in advance.

You do know that you should not need to run the config on the express it should have worked out of the box.

Can you post close up clear pictures of both sides of the pcb for us. Is the wireless jumper plugged on the pcb?

The red circled area is the 485 chip that I messed up on but I seem to get it to work but am not sure if the three pins are supposed to be connected or not.

Isn't the 485 chip in backwards?

Yes Adam your RS 485 chip is backwards
also are your 100uF facing the correct way?

Thank you kpurcell it was the 485 chip I have taken that chip out so many times because of my having problems with the soldering of that section I must have just put it in wrong when i finally got the soldering done. Thank you every one for checking my board for me. I have blinky blinky now.. <la..
