PINK link LED's solid green, all the time

SAAM

I'm playing with a new PINK and I can't establish connectivity to it.
I noticed that the two green LED's on either side of the RJ-45 connector go to solid green (no flashing or pulsing) as soon as I power up, even without a network cable attached.
(I'm supplying power from a HomeWork board.)

Is this the normal expected behavior of the uplink LED's on PINK? Or is it indicitave of a problem?

SAAM,

·· While this is not the normal behavior of the PINK module under normal operating conditions, it may well be when operating it from the H/W Board for power since that board cannot provide enough power for the PINK Module to operate correctly.· You will need a heftier 5V regulated supply.

According to the documentation for the Homework board www.parallax.com/detail.asp?product_id=28158 there are 3 versions of the board. Versions A and B can only supply 50 mA - which is not enough for the PINK module. Version C can supply 500 mA - which should be enough to power the PINK module.

A fresh 9V battery should last 1-2 hours if that's what you're using to power your Rev C HomeWork Board and PINK.

Forrest,

·· Unfortunately, while the Rev C board has a beefier regulator, the 9V battery itself will usually be too weak to handle to current requirements of a module like this.· I'd have to recheck the current draw but I believe it was around 165 mA idle.· A 9V battery wouldn't be sufficient in this case...A fresh battery wouldn't last long.· Using this module we recommend a regulated supply capable of at least 300 mA and not for use with the H/W Board.
