Figure 13 Net-2000™- P25 VCU Network Settings Pop-Up Window
The network settings pop-up window allows the operator to change the network port number for the
communication channel. The default port number is Port 4000. If a different port number is required
enter in the desired port number and select the configure button. Valid port numbers are greater
than 1024 and less than 65535. Port numbers 4001, 4002 and 4003 are reserved by the Net-
2000™ VCU and must not be used.
Output Gain
The output gain setting for the voice codec can be set by the user, however, the default values
should be sufficient for most applications. The gain can be set to 0 dB, -3 dB, or –6 dB. To set a
gain other than zero enter the number into the Output Gain setting box and then select Configure to
initiate the new setting. To lower the I/O gain below zero enter a negative number using a minus
sign in front of the value.
Configure Button
Selecting this button will load the displayed network and gain settings into the VCU. Once loaded
the VCU will automatically switch to the new settings.
Reset to Defaults Button
The reset to default button on the Network Setting Pop-up window resets the value of the Port
number to 4000 and sets the I/O gain setting to zero.
Close
Selecting CLOSE will close the network setting pop-up window.
Reset To Defaults Button
The Default button on the main control page resets the Net-2000™- P25 VCU and puts the vocoder
settings to their default values. Network settings such as Hostname and IP address are not affected
by this Reset to Default button activation.
