-How to connect to the Serial Port of this specific device:\\+Looking through the vents on the left side of the router, near the power plug, three ordinary pin headers are visible. These are the serial port. They can be accessed using thin gripper probes without requiring any disassembly of the case. It may be necessary to remove the sleeve from the probes to make them fit through the vents. Be aware that the 12V pin from the power connector is directly behind the TX pin. If using unsleeved probes there is a risk of accidentally bridging 12V to the TX pin if the probe is inserted too far. Doing so appears to cause permanent damage. Make sure to disconnect the power plug before inserting the probes. It is not enough to flip the switch. 
 + 
 +In order from closest to the power connector the pins are: 
 +  - TX 
 +  - RX 
 +  - GND
