With help of Miyo-kun,

I could configure the picomotor drivers with cable connection and with a Windows application. Its details is now uploaded here.
The setting is the following:
-gateway: 10.68.10.1
-subnet mask: 255.255.0.0

-IP address for ITMX: 10.68.150.18
-IP address for ITMX: 10.68.150.19

Working check will be done soon.
