First time with wismo 228


#1

Hello, I’m trying to use a Wismo 228 with a serial port of my PC and I’m having some problems… and I’m starting to think that I’m doing something wrong that perhaps is obvious for some of you >.<

I connect the serial port to my voltage conversor and I see that Wismo 228 receive the same I sent to it…

But in response of AT or any other command I don’t receive a ok… the signal is something like this…

I think that perhaps the problem is that I’ve not configure correctly the modem…
I sent to it the commands:

AT+IPR=9600
AT+IFC=0,0 (I’m using the 2 wire circuit)…

There is something more to do with it to initialize it??? There is some stupid typical mistake that I’m doing???

Thanks a lot for your time and for read this, i know that my English is not specially good…

Ok, I’ve solved it… I really don’t know exactly how… but this is and advice.

Always try to config the modem in all the possible speeds before try it…
