1. addition to determining assigned device numbers the usbDemon Finder can be used to program license codes into a USBDEMON for various applications such as the Flash Programmer and J SCAN Programming the license code into the USBDEMON allows an application to be installed on multiple machines which can then share the hardware device In order to get a license code for a particular application you need to send the USBDEMON serial number to the manufacturer of the application you are using There is a button in the usbDemon Finder labeled To Clipboard that will copy the serial number of the currently selected device to the Windows clipboard so that it can be pasted into an email The manufacturer will send back a license code that should be copied into the edit box at the bottom of the usbDemon Finder screen Press the Program button to enable the license on the USBDEMON 2005 Macraigor Systems LLC USER S MANUAL Revision 1 0 Appendix A Common OCD pinouts NOTE Macraigor Systems accepts NO responsibility for the accuracy of the following information We strongly recommend that you use the OCD header specified by the semiconductor manufacturer Please refer to the manufacturer s proper data book or reference design for information The pinouts given below may show a subset of the signals specified by the manufacturer General Notes Unless otherwise indicated all headers are male dual row Berg style connectors on 0 12.
