UVC Conguration Parameters
The UVC is been provided with a number of conguration variables as listed in the fol-
lowing table. These conguration variables are stored in UVC non-volatile memory. For
a description of supported network variables for each protocol, refer to Protocol Data
Packet bulletin ED 15065.
