Dear Alan,

Two important issue were missing during compilation of our 
comments. These are related to ether-net controls.
Please add following comments to the previous one.

Best regards,

6. When we define a communication protocols with Ethernet,
   it should be noted that both UDP/IP and TCP/IP are available. 
   UDP/IP method is faster than TCP/IP if the communication link 
   is stable. Some application may use them locally to transfer
   data.

7. As the coexist ether-net control besides easy RS-232 commands ,
   We believe that the VSI-S will use 'socket' for the Ether-net 
   communication as well as S2 system, but we could not find any 
   description in it. If you have another idea on Ether-net 
   communication, please note them. We have already begun to 
   develop our VSI equipment based on the socket 
   If we need to change the method, we have to discuss more.

Sorry for bother you to gather all comments.
Thank you,
Japanese group
