Control BS via Ethernet
Hello,
My notebook is connected·to·a Basic Stamp which is connected to a Parallax Servo Controller.
I control 4 servos. Everything is ok.
I would like to place the BS and PSC 30 meters away from my computer.
Is there a way to send data to the Basic Stamp through a network ?
Thanks for your help.

WiPORT, Zigbee and others also provide "wireless" solutions.
Phil: Do those devices work through switches, etc, or do they require a "straight shot" of just cable?

It requires a straight shot. Although it uses standard Cat5 cable and connectors, it's not compatible with Ethernet switches and routers.
One really nice feature, though, is that each end has a DC-DC converter to boost and then re-regulate the USB's 5V supply to make up for any cable losses. I get a more stable supply with this thing and 100 feet of cable than I do with just a 6-foot USB cable. This makes it possible to power one's remote device without having a separate power supply at the other end — assuming it's a device that normally runs from USB power. An Ethernet device — unless you have a power-over-Ethernet installation — will require a separate supply.

Thanks for the info. I'm working a few things (hobby) that might be able to take advantage of the USB stuff.
There are trade offs both ways. Being able to work throught switchtes, routers, etc. has some definite plusses, but also some significant overhead.
The straight USB also opens up some lower cost solutions for multiple divices. I've seen these with a USB hub on the far end, which means that for tethered robotics, you not only could talk with the STAMP/SX/Propeller, but also stuff like Web cams, microphones, speakers, etc.

With BS et PSC I control several·pan and tilt camera and other devices.
My idea was to connect the Basic Stamp and PSC on an ethernet router :
so I can place the camera and BS·everywhere in my home where there is a network connection.
It seems it's not so easy. In fact I have to convert serial to ethernet and back.
Thanks for your help.

There are other devices (XPort at www.gridconnect.com/ltrx.html for one) that will take care of the serial/ethernet conversion. On the PC side, you access the serial stream via Telnet to a specific port on the XPort. XPort is made by Lantronix. There are other devices that work similarly.
Here is a thread in the propeller forum that talks about other options: http://forums.parallax.com/showthread.php?p=597625
Keep in mind that with PINK, you get the support of Parallax
