My T2-301 came with no cables. Its DB9 provides rs232 (2 ports) and power connectivity, but you'll have to make or buy a breakout cable.
Another US$8 gets you a cable that breaks out power and rs232: https://www.argentdata.com/catalog/product_info.php?products_id=125 The db9 on this cable gets you serial port A on pins 2 and 3 (the standard pins) and port B on pins 7 and 8. You can use this to get a single serial port connected (a computer or GPS but not both). Add a second cable for another US$7.50 https://www.argentdata.com/catalog/product_info.php?cPath=21&products_id=93 and it splits out both serial ports from the first cable, so that you can connect a computer and a GPS simultaneously. While you're at it, you can order a USB to RS232 adapter for a very reasonable US$15: https://www.argentdata.com/catalog/product_info.php?cPath=21&products_id=46 This will get you maximum connectivity to your T2-301 (everything except a GPS cable) with zero soldering. -Jason kg4wsv
