Tunnel Settings

Tunneling allows serial devices to communicate over a network, without “being aware” of the

devices which establish the network connection between them. When any character is transmitted

to the serial port, it gets copied to the network connection.

Tunneling parameters are configured using the Web Manager (see Tunnel Settings on page 46) or

CLI Tunnel Menu (refer to the EDS1100/2100 Command Reference) for the full list of commands.)

The EDS1100/2100 supports two connections simultaneously per serial port. One of the

connections is Connect Mode and the other connection is Accept Mode. The connections on one

serial port are separate from those on the other serial port.

 Connect Mode—Makes an active connection. The receiving node on the network must listen

for the Connect Mode connection. Connect Mode is disabled by default.

 Accept Mode—Listens for a connection. A node on the network initiates the connection.

Accept Mode is enabled by default.

 Disconnect Mode—Defines how an open connection stops the forwarding of data. The specific

parameters to stop the connection are configurable. Once a defined event occurs, the

EDS1100/2100 disconnects Accept Mode and Connect Mode connections on that port.

You can view statistics and configure two tunnels by using the Tunnel web page. When you click

Tunnel from the Main Menu, Tunnel 1 fields display. To go to Tunnel 2, click the Tunnel 2 button.

There are six sub-menus that you can use as follows:

 Statistics—Displays statistics for the two lines. For example, completed accepts, completed

connects, disconnects, dropped accepts, dropped connects, etc.

 Serial Settings—Configures buffer size and DTR.

 Connect Mode—Controls how a tunnel behaves when a connection attempt originates

locally.

 Accept Mode—Controls how a tunnel behaves when a connection attempt originates from the

network.

 Disconnect Mode—Relates to the disconnect of a tunnel.

 Packing Mode—Sends packed data that is queued in larger chunks instead of sending it

immediately after being read on the serial line.

 Modem Emulation—Initiates and accepts tunnel connections using the AT commands.

Echo Serial String Select Yes to enable echoing of the serial string at boot-up.

Signon Message Enter the boot-up signon message. Select a string type.

 Text—String of bytes sent on the serial line during boot time.

 Binary—One or more byte values separated by commas. Each byte

value may be decimal or hexadecimal. Start hexadecimal values with

0x.

Note: This string gets output on the serial port at boot, regardless of

whether command mode is enabled or not.
