• failed: OPT ERR CREATEETHECON FAILED (see the error code in Tab. 1).

6. Remarks:

• connect to a server as a client. Before connecting, make sure that the controller is connected to the

LAN;

• We recommend creating an Ethernet connection by SN (compared with by IP) because IP is likely

to be changed dynamically in LAN under the DHCP protocol. We have provided a tool (Search-

ForControllers.exe) to check SN.
