deeonline Posted November 10, 2017 Share Posted November 10, 2017 Hi, I have a bunch of Somfy RTS shades enrolled into URTSI II module. Everything works as expected. However, I can't get the URTSI to respond when connected to the EA-5 controller serial port. I am using the following wiring RS232 diagram with only one URTSI module http://www.automatedshadeinc.com/files/automation/control4_somfy_zigbee_pinout1.pdf. The drivers are from https://www.drivercentral.io/platforms/control4-drivers/blinds-shades/somfy-blind-driver-v2-proxy/ and have been set up according to their instructions (see attached). However, no matter what shade command I send from ComposerPro interface, the URTSI doesn't respond at all (i.e. the green light never blinks). At the same time, I am able to control shades from URTSI II module itself without any issues. I've verified that serial ports on my EA-5 are working. Logically, seems like this is a cable issue, but I've checked it against the diagram like 10 times already and can't figure out what's wrong. Control4 OS: 2.10 Any idea what else I may try? Any help is appreciated. Thank you. Quote Link to comment Share on other sites More sharing options...
lippavisual Posted November 10, 2017 Share Posted November 10, 2017 I was always under the impression that a RS485 to RS232 converter was needed for these. That may have changed, especially looking at your diagram, it does show a RS232 port. How far is the distance between the Somfy controller and your EA5?

My understanding one can go with RS232 serial connection as long as there is 1) only one URTSI module and 2) the cable length is under 50ft. My Somfy URTSI II is only ~6 ft. away from the controller, so the length should not be an issue. Quote Link to comment Share on other sites More sharing options...
mstafford388 Posted November 10, 2017 Share Posted November 10, 2017 You can do RS232 with the URTSII piece. It's likely a cable issue. Quote Link to comment Share on other sites More sharing options...
deeonline Posted November 10, 2017 Author Share Posted November 10, 2017 I am using this driver from Cinegration LLC https://www.drivercentral.io/platforms/control4-drivers/blinds-shades/somfy-blind-driver-v2-proxy/ Quote Link to comment Share on other sites More sharing options...
ILoveC4 Posted November 14, 2017 Share Posted November 14, 2017 Works great for me. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
deeonline Posted November 14, 2017 Author Share Posted November 14, 2017 OK. I've finally got it working. The wiring diagram that's floating around the net was outdated. I am attaching the corrected one that worked for me with the latest EA-5 controller. Hopefully, it will help others. Quote Link to comment Share on other sites More sharing options...
thegreatheed Posted November 14, 2017 Share Posted November 14, 2017 2 conductors are not enough for RS232. Quote Link to comment Share on other sites More sharing options...

Why not if this is a one-way transmission only, e.g. simplex serial communication? There is no feedback from URTSI II module to the controller.
