1.3 Net-2000™-VCU modes of operation
The Net-2000™-VCU provides the user with two modes of operation VOIP Mode and File Mode. To provide full
duplex real-time communication, the Net-2000™-VCU can channel the compressed bit stream through either the
RS-422 or the Ethernet interfaces to another Net-2000™-VCU.
Alternatively, in File mode the Net-2000™-VCU can Encode/Decode files stored on a PC on the LAN for non-real-
time testing and evaluation. The Net-2000™-VCU remains in an idle state until it gets a command to start and stop
processing (encoding and/or decoding) data that is being sent.
1.4 Control
When connected on a LAN — any PC on the network can use a standard web browser to control the Net-2000™-
VCU through the use of a PC web browser. The user-friendly web pages built-into the Net-2000™-VCUmake it
easy to select analog audio interfaces, select the vocoder mode and to establish real-time, full-duplex communication
across the Ethernet connection. In addition to the control, the web pages display information about network settings,
operating mode and system status. Since the Net-2000™-VCUuses Ethernet, its web page can even be accessed
over a wireless network through a wireless notebook or tablet PC.
The Net-2000™-VCUcan also be controlled via PC connected to the RS-232 interface. Connecting to the RS-232
interface allows for both low level set-up of the NET-2000™-VCU and for control using ASCII commands. Input
and output gain settings for the voice codec can be also specified.
1.5 Protocol
The Net-2000™-VCU uses DVSI’s own UDP interface described in Section 4. This allows users to develop their
own application controls and user interfaces for an endless array of customized applications.
Before using the Net-2000™-VCU, read through this user’s manual in its entirety.
