To recieve logs, '''you will only need to connect the ground and TX wires of your cable'''. To send information through the serial console, you will also need to connect the VCC and RX wires.
Plug '''the TX (output) wire''' from your cable '''to the RX (input) line''' on your adapter. (You'll need to do the reverse - RX to TX - if you want to send data.) '''Note ''' that some schematics for serial cables mean "TX port on your UART board" by "TX", so if you don't get any output - try swapping the two, and note it down on the wiki.
Then, plug the other end of the cable into your device. Some devices may automatically boot up when the jig is plugged in - if your device starts up without you pressing the power button when you plug the cable in, it means that the resistance is being detected and the serial mode has been triggered.

== Troubleshooting ==
 
1. Make sure you are using the correct connection settings: baud rate, parity, etc.
2. Make sure your ground connection is stable. If in doubt, replace the cables.
3. If you're only getting partial output, you may need to use a different resistance between the ID and Ground pins. Some devices return different things depending on the resistance given.
4. If you're not getting any output, try only plugging in the RX cable to your UART board. You may have swapped the RX and TX cables.
