Using the Terminal Server—Typical Example
The following describes a Terminal Server implementation in a radio
network. Figure 32 below is referenced in this discussion.
Figure 32. Terminal Server Example
IP/Radio Network Setup and Configuration
The following conditions are assumed for this example:
• Radio (RF) link is good between AP and Remote 1, and AP and
Remote 2.
• IP addresses are properly configured as shown in Figure 32.
• Packet w/MAC mode is enabled in all radios, and the
is set to
Type AP
• Ethernet Bridge is enabled in all radios.
Serial Addressability
This example shows that it is possible to communicate to specific serial
devices (e.g., PC 2 COM1, and PC 3 COM1) over the radio network.
Note that TCP is used as the transport layer for communication here,
which provides data reliability at the application level.
1. Configure Remote 1 and Remote 2 by navigating to the
screen and setting the parameters as listed below.
COM2 Configuration
(Note that an Ethernet connection to Remote 1 and Remote 2—not
shown in Figure 32— will be required for this step unless Serial is
used.)
Status: Enabled
Mode: TCP Server Socket
Local Radio Port: 30000
Connection Timeout: 0 Seconds
Persistent Connection: Yes
