Abstract
Connecting other devices over the internet than just PCs is becoming a common place now.
There are web enabled embedded devices almost everywhere. By combining the internet
world to the embedded devices, it makes it much easier to be able to achieve the real‐time
data from across any location. This thesis aims to web ‐ enable an embedded device, a
power supply using a web interface. The development will be constituted with a
combination of the correct product and the technology. The technology that we consider
using for this project is the SNMPv1 protocol.
SNMP (Simple Network Management Protocol) is now a days [sic] the key enabling technology,
while, with the development of embedded internet, manufacturers are required to “webenable”
the configuration and management of their products. Thus the integration of SNMP
and Web in embedded devices will make products competitive.
The main task in achieving the aim was the programming and the communication between
the power supply and the Lantronix Xport Pro device. The programming was done on the
Linux environment for the Xport Pro device and then the integration for loading the web
pages were [sic] done using a GUI software through FTP server. The majority of the work
involved in this project was developing the correct data and making a stable communication
link between the power supply and the Xport Pro device.
During the development process, several issues were encountered with the software as well
as the Xport Pro devices. The loading of the software on these devices consumed most of
the time as it kept on encountering faults which made the devices dead. However, with the
help of the FTP server on the windows machine, it was much easier to connect the power
supplies and re‐load the software onto the Xport Pro software. Testing was the easiest task
and real‐time data was displayed on the web pages with no other faults.
