Making a Console debug Interface for KWGR614

This section contains inst ructions on how t o make a cons ole interf ace to a NETGEA R KWGR 614 wireles s router
for developer’s firmware de velopment and debugging.

KWGR Open Source Guide (Rev 2.0)

Provided below is an exa mple schematic using M AX3 232, the
(TI), to make a console board.

(Datasheet of the MAX3232 can be found on TI web site at http://focus.ti.com/lit/ds/symlink/max3232.pdf

The DB9 (Male) connector is wired as a DCE (thin k of t h is as a peripheral serial port), and can be conne cted
directly to the serial port on a host PC. This gives you access to the built-in serial console on the router (using the
protocol of 38400bps, 8 data bits, none parity, 1 stop bit, without flow control).

Connect the console board to the pin header (J303) on the router boar d.

RS-232 Line Driver/Receiver from Texas Instruments

)

KWGR Open Source Guide (Rev 2.0)

The pin-out of J303 on the KWGR614 board is as follows:
Pin 1: VDDH (3.3V)
Pin 2: TxD
Pin 3: RxD
Pin 4: GND (Ground)

There are 3
adapter kits at:

http://www.compsys1.com/workbench/On_top_of_the_Bench/Max233_Adapter/max233_adapter.html

Make sure the adapter board is connected correctly to the corresponding pins of J303 on the router board.
