Altium's USB JTAG Adapter enables you to create a JTAG link (incorporating multiplexed Hard and Soft JTAG chains) from your PC (running Altium Designer) to a NanoBoard-NB1, using a USB connection.
On the PC side, connect the USB JTAG Adapter to a spare USB port on the PC, using the supplied USB cable.
On the NanoBoard-NB1 side two connect options are possible:
1) Use the 26 pin connector included in the USB JTAG Adapter package to connect the NanoBoard-NB1s parallel port header. Please note that older versions of the USB JTAG Adapter do not include the 26 pin connector. Then option 2 can be used.
2) Connect via the use of nine of the flying leads from the supplied JTAG flying-lead cable (10-way IDC – 10 flying leads). The applicable flying leads are connected straight into the relevant pins of the NB1's parallel port header (HDR3).
The following table lists the flying leads to be used and which pin of the parallel port header they need to connect to.
