. The DS2000-TS can be configured for Terminal Server and IP routing applications. This 

chapter illustrates how to configure a basic Terminal Server application. It is assumed that the physical 
network connections have been made to the DS2000-TS
, that the network designs are complete, and 
that all configuration data are available.

XAMPLE

The Terminal Server feature allows for TCP/IP applications to interact with Async serial-based devices over 
an IP-based network. Asynchronous data streams are packetized into TCP/IP formatted frames using 
traditional terminal server functions. The frame is then routed over an IP network. 

To configure the 

DS2000-TS

 to act as a terminal server, the user must do the following:

Configure the Router features

Enter the IP address for the Ethernet port (example in 

Figure 3-1

, 192.168.1.1)

Select the discovery protocol being used

Configure the serial ports

Assign a port name

Assign local socket number

Set line speed and parity

Assign DSS usage

Assign the proper profile

Figure 3-1

 shows a very basic network. The following procedure describes how to configure the

DS2000-TS

 on the right, i.e. a typical remote site. The configuration allows the IP-based host system on the 

left, labeled B, to send and receive data from all serial devices configured on the 

DS2000-TS

, labeled A. 

Refer to this figure during the configuration to understand the connection process. The procedures use the 
configuration data from the figure below. Note that the Router at location B (which can also be a 

D

) also requires configuration to complete the end-to-end network path.
