If telnet to that TCP port does not work then EPICS won’t work.  The fact that you can ping just means that the device exists.

 

Are you sure that port 1 is correct?  On the devices I have used the first serial port is typically TCP port 2001 or 4001.

Hi,

 

When I use telnet from my Linux machine:

  telnet 192.168.0.21 1

I also get connection refused. But ping 192.168.0.21, it works well.

 

I cant find the TCP Server Mode attribute of the port of the NI Ethernet/RS232 convertor(4 ports) , and the port likely neednt to be configured.

 

Then, Is the port number the convertors port num or the device port in the machine? how should I set the port number in drvAsynIPPortConfigure?
