Serial Tunnelling

Brainboxes Ethernet to Serial Devices have a feature called serial tunnelling.
connects two devices together to create a serial tunnel which extends the serial link over an Ethernet
connection. When serial data is sent, it is converted to Ethernet packets by one Ethernet to Serial
device, and then transmitted over the network, then unpacked and converted back to serial data by
the other Ethernet to Serial device. An example of tunnelling is shown in the diagram below.
Serial tunnelling is set up using the webpage interface. In the following instructions there are two
devices which are referred to, the local side which is the device that you are connecting from, and the
remote side which is the device you are connecting to.
1. Go to the web page interface of the Local ES Device using a web browser.
2. Navigate to the page of the serial port you want to use.
3. At the bottom of this web page is the device tunnelling section.

slave. Enter the Remote IP Address and Remote TCP Port number of the ES device you want
