Hi, I see that the EHS6T LAN doesn't have USB. I understand the reason for this (it's being used by the ethernet controller) but I'd like to ask: how do we program it? The concept board and other terminals connects via USB for debugging and programming. Thanks - Jason

Hello, you can connect your terminal via serial interface as this interface is available. It will be hard to develop and perform online debugging, but you can easily load created JAR and JAD over serial and, of course - manage them with AT^SJAM. Please remember that EHS6 module works as slave in communication with MCU. Heavy ingerention in module (e.g. switching serial allocation, etc) may cause the terminal to malfunction. Regards Jedrzej

OK, well that doesn't sound too bad. I have a concept board so I could continue to use that for development and then load the image onto the terminal. I do plan to use EHS6 as a standalone processor but my application is quite simple - basically I have an ethernet device and a serial device and I need them both to be routed through the internet (with a little bit of processing done on the serial data - this is implemented in Java). So if I understand the EHS6T-LAN correctly, I could plug in the ethernet device, configured to use a static IP, and that would automatically routed through the EHS6/3G connection. Then, I can add my small amount of serial processing code on the Java module (already implemented on the concept board). Is there any performance information on the ethernet of EHS6T-LAN? The datasheet says HSPDA up @ 5.76 Mbps - will the terminal be able to stream data via ethernet at or near this rate, or is it slower? Thanks very much, Jason

Hello, it looks like LAN terminal is not availale for customers yet. Due to that there is also no detailed documentation available. You need to know that Java and LAN use different PDP contexts so they will have different IP addresses. Regards Jedrzej

I have the same problem. 

I am just get starting with this module, but i can't get a serial connection under windows 7.

no serial connection

Is there any possibility to develop and perform online debugging with the Ethernet interface?

Hello,

As I understand you only have a serial connection to the module, no usb. I assume that you have the Java User's Guide document and follow the described steps. 

Have you connected and powered on the module? Have you closed other connections to the module (terminal)? Have you tried to communicate with the module with some terminal program and was it possible to send commands and receive replies? 

Unfortunately the Ethernet interface cannot be used for module debugging.

Regards,

Bartłomiej

Thank you for reply.

Accroding to the Cinterion Java Terminals Hardware Interface Description (EHSxT_BGS5T_HID_v07), I tried to connection the module with SSH and FTP via Ethernet, It was successfull.

and I find this in the Java User Guide Document,

Driver?

It looks like I didn't installed the driver for the "Cinterion EHSx Java Debug Modem Ser". Maybe that is the point?

I managered to install the modem driver by using add modem in the Phone and Modem (Control Panel) settings. and I can connect the module via Hyperterminal. 

But I still have problem to etablish the IMP Debug Connection. Try to repair installation and scanning COM ports many *****. (Win 7 64bit)

“No supported module found, the debug RAS-Connection has not been updated!”

if i running the HelloWorld Demo. 

Debug RAS connection is not installed!

Passing control to external device emulator...

Best Greeting!

Hello,

Please make sure that you don't use the port at the moment of installation (any terminal open etc.), the module is powered on and connected to PC.

Please run the setup once again but when there is an information that scanning will start please make sure that all drivers are already reinstalled and make sure that windows is no longer searching for any drivers. Then start scanning by pressing Next button.

Regards,

Bartłomiej

Hi everybody

 

I have the same problem.

 

I just started to study the Gemalto´s Modem Family and something stopped me on my research.

 

As I know, the EHS6T - LAN doesn´t have the usb port and when I connect the LAN port using a patch cord, the computer doesn´t detect any serial port.

 

I´ve tried to connect with a serial simulator port program and with a combination of wires just like the Cisco routers and switches do, without favorable result.

 

Is there any solution or any procedure to connect the EHS6-T modem to the computer that allows me to see the serial port (COM #)?

 

Another solution that I´ve been thinking is with the FTP connection ones I already have finished my program on Eclipse.

 

Please help me to solve this issue.
