Serial connector

DNS-300 has soldered 5 pin COM-TTL connector (JP1) like DSL-G604T. To use it with PC you need a RS-232 ↔ TTL adapter.
I've used schema from McMCC site: http://mcmcc.bat.ru/dlinkt/data-cable/scheme.jpg
Local copy Serial Connector

I've disconnected pin 1 from RS-232 on this scheme to use it under WinXP HyperTerminal.

Also you can use USB to serial cable described here: How to connect USB only equipped PC to Serial Console of DNS-300

Serial settings: 19200, 8 bit, no parity, no hardware sync.

JTAG

It seems DNS-300 has unsoldered 20 pin JTAG (JP6) on board. Info about this JTAG connector can be found here: http://hri.sourceforge.net/tools/jtag_faq_org.html#_Toc63218717

JTAG on DNS-300 has incorrect pins numbers than in JTAG FAQ
