XCM - XRF Config Manager is an application used to manage a XRF device. To easily check if you can communicate with your XRF, use the "Search" button. This will search every available COM port for an XRF. To make changes simply alter the text boxes, and once you have finished press "upload config" (this will write the config to the XRF). Click ATAC if you want these changes to be made live straightaway, and use ATWR if you would like the changes to be permanent over a power up.
