Wanted: Linux embedded module w/ RS232 and ethernet

Started by Udo Giacomozzi September 29, 2004
Hello everybody,

can somebody suggest me a embedded linux module with RS232 and Ethernet 
interfaces? Not much more is needed. 

The RS232 interace is used to attach a GPRS modem module.

I want to use one of the following configurations:

1 - FTP server for the ethernet side, upload then via GPRS to another FTP 
server

or:

2 - daemon that loads a FTP file from the ethernet side and then uploads it 
via GPRS

As you see, that should be a Ethernet<->RS232 gateway for a ethernet client 
that doesn't understand PPP.

I searched on linuxdevices.com and google but simply can't find a device 
simple and cheap enough to match my needs. There are too many out there...

Thanks for any response!

Just to make it clear: I just need a linux embedded module with a linux system pre-installed. The application software would be written by me... Udo

Perhaps the linksys routers are something for you.

Cant find it right now, but I seem to recall that 2*RS232 was
available on the inside of the box, not as external connectors.

Hi Udo,

Lantronix has a small RS-232 <-> Ethernet Converter which has almost the 
size of a RJ-45 connector, called XPort 
(http://www.lantronix.com/products/eds/xport/index.html).
Important: You don't need to care about the kernel, the compiler and so 
on. I think it's a good solution if You don't have a big amount of data 
to transfer.

I know that there is also a similiar solution including a Net+Arm chip, 
which is completely user-programmable (except bootloader).

I hope this helps,

Michael

Digi ConnectME, also now available in a WiFi version. Bob McConnell N2SPP

On the WRT54G V2 there is 2 ttl level Serial ports inside , all you need to add is the MAX232 (233) , they are on pcb board on an unpopulated plug , 2x5 pins like a jtag plug (needs to be soldered in also). It contains a 200Mhz MIPS , but no means of interfacing a disk or Flashcard Carsten

Another solution would be the "ARM Industrial Module AIM 711", which is running eCos as OS. It has one ethernet and a serial interface. Look at http://www.visionsystems.de/arm7.html for further informations. Best regards, Roland
