Any combination of the three VRC numbers may be entered in the selection fields. Figure 32
illustrates the relationship between the VRC settings and the routing of data between units.
Figure 32. Virtual Radio Channel (VRC) Concept
Terminal Server COM1/2 Configuration
The radio's Terminal Server feature allows IP addressing of the COM1 and COM2 serial inter-
face ports. Data from these ports is sent over the air as encapsulated IP packets. At the receiving
end, the data is decapsulated and delivered to the appropriate COM port(s). In contrast to the ra-
dio's IP Payload feature, having a terminal server at the Remotes means that Ethernet data can be
delivered to specific devices connected to these radios. Terminal Server settings, examples, and
additional benefits are described in the following paragraphs.
The image on the following page, shows the Device Manager's
Terminal Server COM1/2 Configura-
screen. Two such screens are provided in the Device Manager; one for COM1 and another
tion
for COM2. Here, the behavior of the terminal server is set and applied. The Terminal Server
must be enabled and configured in all radios requiring IP encapsulation of serial data. Proper
configuration of the serial ports is also required, using the section of the
Communications Ports
Device Manager.
