5.1 INTRODUCTION
This chapter provides details of how radios should be configured and
connected for specific applications, such as IP-to-serial and
serial-to-serial configurations. Only the most relevant parameters are
shown for the sake of simplicity. All other parameters are assumed to be
set at their default values.
5.2 IP-to-Local Serial Application
Example
You can use either UDP or TCP to establish communications with the
entraNET radio. The choice depends on the type of device you are
communicating with at the other end of the IP network. This example
uses TCP to illustrate this function.
In TCP mode, the transceiver remains in a passive state, offering a
socket for connection. When a request is received, data received by the
AP serial port is sent out through the IP socket and vice versa, until the
connection is closed or the link is interrupted. The TCP session has a
10-min time-out. If inactive for that time, it ends the session.
The
transceiver offers the port for connection again after this time.
See
Figure 5-1 and Table 5-1 .
Establishing a Connection
From the PC, establish a TCP connection to the IP address of the
Remote transceiver and to the IP port as configured earlier (typically
30011). You can use a telnet client application to establish this
connection. Data can now be sent between the PC and the endpoint
device.
