You can attach a 3.3v TTL cable (LV-TTL) to the UART on syscon (UART0_TxD, UART0_RxD). (Convenient solder points are available on JSD-001 / JTP-001 by the NOR test points. They are marked as '?' in [[:File:JSD-001 NOR - nor testpoints.png|marcan' noraliser / judges' NORway install picture]], closest to the ground at the bottom - RX is left, TX is right) Baud rate is 57600. There is a simple plaintext protocol involved. This varies on different syscon models. Example:
