Configuring TCP Socket Communication, Click Serial Ports

7.Check Automatically connect to a ... Be sure to specify the following:

•Hostname or IP address that will be the destination

•Service

•Destination TCP port number, which determines the type of connec- tion for this user (such as 23 for Telnet)

8.Click Next and Verify the settings.

9.Click Finish to save settings.

Configuring TCP Socket Communication

TCP socket communication enables serial devices to communicate with each other over an Ethernet network as though they were connected by a serial cable.

This section describes how to use the web interface to configure this Digi device for the following:

•Inbound connections, that is, connections that are initiated by the device on the other side of the network

•Outbound connection, that is, connections that are initiated by the device connected to the serial port

Procedure for Configuring Inbound and Outbound Socket Communication

1.Access the web interface by entering the device server IP address in a browser’s URL window.

2.Log on to the device server as root. The default password is dbps.

3.Click Serial Ports.

4.Click the port number you wish to configure.

5.Click Change Profile.

6.Select TCP Sockets and click Apply.

7.Enter the parameters for the appropriate connection. Use the context sensitive Help for additional information.

Configuring UDP Multicast

The Digi One and PortServer TS devices are devices capable of UDP multicast. UDP multicast is used to send serial data over an Ethernet cable to one or many hosts at the same time. UDP is a connectionless protocol, meaning UDP does not need a protocol, but is sending data without any form of acknowledgement or error correction. Up to 64 devices can receive a UDP multicast at one time. Both the transmitting and receiving devices must be configured properly for UDP multicast to work.
