Hi
Please could any one help me .I have a Sensor have it's own interface but I want to put my own interface that communicate with the Sensor by using Visual basic .I don't Know how to take the data from the Sensor and use it in my own interface

study the old interface and prepare a specification containing command and the response obtained.

try sending the same command with your own code and obtain response.

u could b more specific by adding your code to understand the difficulties u r facing.
