The H/W version is written on a sticker on the bottom of the box.

There is an Annex B (ADSL over ISDN) version of this router, the DSL-684T. It should work with the same firmware, but please add it to the DSL-5xxT/G6xxT family page if you have tested it.

Opening the case

Note: This (might) void your warranty!

The router is pretty easy to open, there are just two screws under the case. No warranty stickers in the way!

Once opened, two more screws (and the backpanel) hold the board to the case. There isn't anything interesting on the bottom of the PCB, though.

The ACX-111 wireless card is under the metal shield on the left.

Serial

JP6 (5 pins) represents one serial port (3.3V), the only JP with a header soldered. When looking on the LEDs (front) and having the power and ethernet ports on the back JP6 is on the right and has the following pin-out from left to right:

  • TX
  • GND
  • Vcc (3.3V)
  • GND
  • RX

JTAG

It appears to have a JTAG header (untested). See JTAG tools and port.jtag for more details.
