Hi! I'm trying to control via a PACA unit a series of ILT Somfy motors. I have connected to the PACA un Port 1 a RJ45 cable to a RS232 to RS485 convertor and outlet will control the Somfy motor. So far I have this programmed [QUOTE] once (GetLightingState("Arriba") = ON) then begin OpenSerial(1, 1, 4800, 8, 1, 0, 0); WriteSerial(1, ##$F2#$FB#</body>#</body>#</body>##$FF#$FA#$FE#$FE##); CloseSerial(1); end; [/QUOTE] Also I have a Saturn 4 button keypad, and a button is program to turn ON "Arriba" making the blind to go up, but it is not working. Do you have any ideas of what can I do?? German
