first the unlikely idea:
have you check in the webinterface that only one station is connected
via the Nport? Normally it is set to allow just one station per port
therefore it should be just one station. For deugging it is helpful to
allow a second station und connect via telnet to see the response
traffic on that port.
That works very fine if you got an CR as line end. For the TDK it's not
very pretty because it overwrites the same line thus you can only see
something is happening here. 
That bings us to point 2. In your proto file you are using LF as line
end character.
TDK manual 7.5.3
"The end off message ist Carriage Return (ASCII13) The power supply
ignores the line feed (0x0a)."
