Hello,
I would like to know if someone have the CMUX working with the evaluation board EVK V3 USB or if don´t work at all with this board.
The Telit program simply alternates between “Connecting” and “Error”, even after the script starts executing.
Thank you
Hello,
I don’t know about the USB board but I was having the same problem with the EVK V3 RS232. I solved it by short-circuiting pins 6 and 7 in the board RS232 connector. That way the DSR signal is brought up whenever RTS is up. Actually the module should control the DSR pin but it appears to be unconnected in this board.
I can confirm that connecting pins 6 and 7 on the RS232 connector is required. Also remember that you need to connect whatever terminal app. (HyperTerminal…) within the ten second period after the unit powers up and before the enabled script starts to execute. This threw me for a loop at first and was constantly receiving the Connecting, Error loop when I attempted to connect after the ten second period was up.
