Quatech DSE-410D manual Heart Beat Connection, Quick Start

Heart Beat Connection

The Heart Beat Connection provides an extra measure of reliable communications assurance in Virtual COM Port Mode or Paired (Tunneling) Mode. This feature restores the TCP connection if communication is temporarily lost at either end due to loss of power or Ethernet connection.

Without this feature, a device that loses a connection and stops communicating would not be able to reconnect without human attention to correct the problem. A TCP data connection can be lost when there is a power failure or temporary loss of an Ethernet connection on either the client or server.

If a loss occurs, the Heart Beat feature will try to reconnect the TCP data connection every 5 seconds until communications is established again.

The Heart Beat feature is not available when running in UDP Mode.

Quick Start

This section lists the steps needed to start using the DSE-410D.

Please familiarize yourself with the connections, indicators and switches before beginning. See chart and diagram on page 7.

There are three ways to configure the DSE-410D for your network and serial devices. We recommend the first method if using a Windows operating system.

1.Ethernet connection using the Quatech DSE-410D Manager under Windows

2.Ethernet connection using the Telnet VT100 Terminal software

3.RS-232 connection in Console mode using VT100 Terminal software

The DSE-410D can be configured on your network using a standard Cat 5 Ethernet cable, or to the Ethernet port on your computer using a crossover cable. Use the DSE- 410D Manager utility with Windows or use Telnet for configuration without Windows.

With Console configuration, an RS-232 Crossover (null modem DTE/DTE) cable is usually needed, as the DSE-410D ports are configured DTE for RS-232. Set the mode switches to Console mode, (SW 1 - ON, SW 2 - ON, SW 3 - ON) before configuration.

Step 1: Decide which method to use for configuration and operation.

If using the Console mode for setup, refer to the Console mode section, Chapter 9, and Chapter 5, then power up the DSE-410D.
