Here is an alternative

href="http://www.comtrol.com/tag/1200058">1200058 getting your Arduino

(and other PIC)

attached to your networking (ethernet) - work with an older NSLU2!

The NSLU2 is 3.3v and Arduino is 5v, even

though the NSLU2 and Arduino both talk TTL.

Quick remedy - add a resistor!

Only 3 wire connections are required - pins 3, 4 and 2 relating to the NSLU2. You may not are planning to relate

the energy pin.

In each the desk below, look for the white-colored stripe - this is the power pin.

NSLU2 - pin-away from the J2 serial

dock

Pin 1 - 3.3v, pin 1 possesses a whitened stripe next to it

Pin 2 - RXD, are given from Arduino

to NSLU2 (must-have resistor)

Pin 3 - TXD, send from NSLU2 to Arduino

Pin 4 - GND, flooring association

This post is printed in referrals on the way to "Freeduino" - a Better

business bureau (uncovered bones table) variety. Ensure that things are all operated out and unplugged. Then, relate the TTL pins tagged "RX", "TX" and "GND" in

the Better business bureau to a

appropriate pins towards the NSLU2. The 4 serial port TTL pins onto the NSLU2 are visual just under the battery off to the right.

You are required to set a 10k resistor within the

Arduino along with NSLU2 on pin 2 to the NSLU2 consequently the

5v coming from the Arduino are minimized to safe concentrations.

Now power along

the Arduino and NSLU2 this really is flased with Debian (SlugOS if do the trick also). Mount minicom (apt-get) and

initiate up minicom and set up the serial harbour tottyS0 and 9600, 8N1.

The TTL pins/port on the Arduino and NSLU2 are functional you should now see the output from the Arduino

if the connections are correct. If you do not see anything, be sure you have pre-programmed your Arduino with a program

that outputs text at the proper baud rate. Also you could try driving out of

either models, potency backup and try yet again. If you have made

other hardware mods such as overclocking on the NSLU2, it is possible the serial port will not work.

Make sure you arrange a 10k resistor in between the

Arduino as well as the NSLU2 on pin 2 to the NSLU2 consequently the

5v coming from the Arduino are decreased to trustworthy thresholds.

Now power up in the Arduino and NSLU2 that is definitely flased with Debian (SlugOS will want to task also). Deploy minicom (apt-get) and start up minicom and set up the serial slot to9600 and

ttyS0, 8N1.

The TTL pins/port on the Arduino and NSLU2 are functional you should now see the output from the Arduino

if the connections are correct. Be sure you have pre-programmed your Arduino with a program that outputs text

at the proper baud rate if you do not see anything. Also try out driving off the two products, potential back

up and try just as before. It is possible the

serial port will not work if you have made other hardware mods such as overclocking on the NSLU2.
