View Full Version : communication to ethernet
01-25-2007, 10:00 AM
I am trying to use a BS2 to send I/O data through an ethernet port to a computer database.
I think I have the serial part of the communications figured out.
Is there an easy way to convert to Ethernet-or should I just use a port server card?
Any input is appreciated.

There are inexpensive ways to convert from serial to ethernet if you have serial access to a pc. you run a server on the pc that talks to the serial (BS) and the ethernet. I think if you Google for serial to ethernet you will find what you need.

The BS2 can't directly send info via ethernet. You would need some kind of interface.
How is your system set up right now? Is the BS2 connected via serial cable to a networked computer, or is it standalone?

Here is what we all need . . .
I have three of them. I have had e-exchanges with Elexol and told them they needed to produce a wireless version of the Ether I/O 24 module so one would not have to lug around a (stripped down?) access point on the robot. They thought that was a very good idea. But, no product has sprung from that "very good idea."
You are what you write.

I noticed the SX52 chip on that board.

That elexol device only supports UDP communication. This is highly limiting, especially if the user wants to use it on the internet where connectivity is not always guaranteed. It would be better to use a device that actually supports TCP, be it telnet, http, ssh, etc. If I were you, I would recommend a PINK, siteplayer telnet / server, or an xport. All of these devices support some form of a TCP to serial connection.

I looked into the port server similar to elexol-still a possibility
My units are stand alone & monitor machine inputs-
The plan right now is to use the BS2 devices via wireless hubs.
I will look into PINK...

Here's a wireless option: www.selmaware.com/appbee/home.htm (http://www.selmaware.com/appbee/home.htm)

This looks like the ticket-I appreciate the direction.
I will keep you guys posted-If interested.

No problem. Please note that the modules aren't wireless ethernet, but are networkable. On the base station pc it should be simple enough to run a program or script to receive & parse the data and update the database with the information.
