CONFIDENTIAL INDEX CONTENTS 43 gt DEBUG CABLE QUICK REFERENCE It is not strictly necessary to solder the debug header in place if it is inconvenient for you to do so However the header pins are not a tight fit in the holes in the pcb so if you do not solder the header in place you may have to apply a slight pressure on the header to ensure good electrical connectivity 2 1 1 Modifying and routing the debug header Extending the header pins The debug header can be modified using Molex headers or equivalent Attaching these headers as shown in Figure 3 gives longer pins for insertion and the plastic frame can be used to provide some compression force to hold the header in place if it is not soldered Molex 0 1 4 way header square pin part number 22 27 2041 Available from http uk farnell com Attaching a ribbon cable In some circumstances for example a test laboratory you may need to use the debug facility with the STB case fitted It is possible to solder a ribbon cable onto the pcb where the debug header would normally be fitted and then route this cable outside the case If you solder a ribbon cable between the debug header and the pcb ensure you connect the cable pin to pin For example use the red wire between the header pin and the square solder pad which it would normally be fitted into then connect the remaining cables in the correct order Routing th
