I have a gigantic knot on my forehead from banging my head against the wall all afternoon. Been trying to get my OPII to control a single Somfy motor for a roller shade, but I'm coming up short. Can anyone review what I've done and let me know if I'm missing something or provide a recommendation on the next troubleshooting step? Here's what I've done:
First off, I used Relleum's guide that he posted and didn't deviate much at all.
Equipment
HAI Omnipro II
Somfy ST30 RS485 Motor
Somfy Power Distrubtion Panel
Meanwell 24v Power supply
Somfy DCT tool
1. Installed the Power supply and the power distribution panel.
2. Wired up the motor and the shade worked fine with the DCT setting tool.
3. I took a CAT5 cable, cut off one end and added a 6-pin RJ11 jack.
4. I configured serial port 4 on the OPII with 4800 baud and the Somfy ILT function.
5. I changed the jumper on serial port 4 to RS485 and plugged in my cable to the OPII and the Somfy distribution board. The red LED on the Somfy distribution panel lighted so I figured this was a good thing. I tried the cable two ways: 1. Pin1/RJ45 to Pin5/RJ11 & Pin2/RJ45 to Pin4/RJ11 2. Pin1/RJ45 to Pin4/RJ11 & Pin2/RJ45 to Pin5/RJ11. The second configuration got the LED to light, but the shade isn't controllable with either configuration.
6. I downloaded the ILT software tool and converted the Node ID on the motor to a hex value.
7. I configured unit 241 on the OPII as Somfy ILT and put the hex value above in as the Address/Node ID.
So at this point I was feeling confident (always a bad sign). I have SuperLink on my Android phone and I tried turning the unit off, on, and to some percentage. Nothing happened. I went to one of the keypads, nothing. I tried PC Access, and nothing.
I got back on the ladder and checked the shade again with the DCT setting tool. It was working so the motor is getting power. I then measured the voltage of the RS485A and B lines where the motor pigtail connects to my wall wiring and I was able to measure about 2v between the two pins so there's some sort of voltage signal there. Oh, and just to confirm that three pin connector is the one I have connected to RS485A&B. The green wire of that 3 pin/wire is wired to the negative conductor of the power supply as shown in Somfy's documentation.
I took the motor out of the tube and verified I got the Node ID correct. I converted the address again and verified it was correct in PC access.
Now I'm stuck. I don't know what else to try at this point. Controlling the unit from all the possible places doesn't seem to get the signal sent from the OPII to the Somfy motor. Any troubleshooting pointers are appreciated. I'm really hoping I've done something boneheaded and I just can't see it.
Thanks in advance,
