UVC CONFIGURATION PARAMETERS
The UVC has been provided with a number of configuration variables
as listed in the following table. These configuration variables are stored
in UVC non-volatile memory.
For a description of supported network variables for each protocol refer
to Protocol Data Packet bulletin, see Table 4.
Continued on next page.
The software ServiceTools™ can be used to adjust parameters not
adjustable through the LUI.
