Hello, 

today tryed houres to connecting the micromaster 420 of my kaeser compressor to my laptop with the connection kit (MM4 Connection Kit)  i bought of siemens. 

first tryed with my laptop : 

-installed V5.3 starter software 

-setup com port usb to serial to "com1"

-setup in starter software “PC COM-Port (USS) to com 1 / baud 9600/...

cannot connect

*second attempt:

-installed on old laptop with serial port.... doesnt support xp 

*third attempt (because i was thinking the serial to usb adaptor was the issue...)

 -used desktop with serial port and win10

-installed V5.1 starter software

-setup serial port in windows to com1 /BR 9600/...

-Setup in starter software  “PC COM-Port (USS) to com 1 / baud 9600/...

Nothing again no connection....

so after tried these steps above over and over i dont know what it can be if i use the com directly and setting like in manual... 

settings in MM420 is did is 

P700 =4

P2010.0= 6

P2010.1=6

p2011.0=0

p2011.1=0

P2012.0=2

p2012.1=2

P2013.0=127

p2013.1=127

Is there anything i forget to do for this setup? 

please any advice what this can be? 

thanks a lot
