Device Specific Terminology
On at least some WD N600 devices the ART-partition is named “radiocfg” in /proc/mtd. (knowing this could save you some time and/or allow proper pre-configuration backup.)

There seems to be a 5 x pin header and a 14 pin (not connected) test connector on the mainboard.
Looking under the main 'can', the CPU is:
Next to that, there's what looks to be 2 x RAM chips:
Under the second smaller 'can', I see another Atheros Chip:
The UART is accessable via JP1 (which already has a header connected!). You will need a TTL to RS232 (ie a MAX232 circuit) to utilise this. See picture further down. The pinout is:
[TxD] [GND] [3.3v] [RxD]
