Need IP code advice for Panasonic Projector

[rofredi]

I am trying to write serial code for a Panasonic PT-DZ13KU projector.  I have tried the following variations to turn the projector ON to no effect:

30 30 70 6f 77 72 31 0d (ascii = "00powr1\0d") and 25 31 50 4f 57 52 20 31 0d (ascii = "%1POWR 1\0d")

These commands generate at "ERR1" error message.

Any ideas?  Thanks!
