Hi, sorry, me again!

The iTach WIFI2IR inputs can be set to accept a sensor which I have done and sending the command getstate,1:1 in Hercules returns a value state,1:1,0{0D}. I have set up 2 way feedback setting flags for state,1:1,0{0D} and state,1:1,1{0D} with maintain constant connection but it is not working. I think its to do with the format the command is sent - if I put anything other than getstate,1:1 in Hercules, e.g. getstate,1:1\xOD, it comes back with an error message - ERR_1:0,003{0D}. Equally, after sending getstate,1:1 in Hercules, if I don't press the return key quickly, it also comes back with error message ERR_1:0,003{0D}. I've tried sending the command without any command suffix in Demopad but still no luck
Any help would be much appreciated....
Thanks
Chris
