Abstract:
A method for supplying power to a remote device via a network connection, comprising the steps ofapplying a first test condition via the network connection to the remote device; measuring a first test result from the application of the first test condition to the remote device; applying the first test condition to a reference circuit; measuring a second test result from the application of the first test condition to the reference circuit; applying a second test condition via the network connection to the remote device; measuring a third test result from the application of the second test condition to the remote device; applying the second test condition to the reference circuit; measuring a fourth test result from the application of the second test condition to the reference circuit; calculating a first difference between the first test result and the third test result; calculating a second difference between the second test result and the fourth test result; calculating a third difference between the second difference and the first difference; comparing the third difference with a predefined range; and applying power to the remote device upon the third difference being in the predefined range.
