The S3 is an old timer that uses 2400,N,7,1 protocol instead of the more common 2400,N,8,1 that the other timers use. Make sure that the protocol is correct and try again. Always use Procom or Telix or even Hyper terminal to check the output. Programs have a bad habit of not displaying the true result.
