Hi All,
Back in April this year there was a few posts to this group about the new embedded x-port server from Lantronix.
I am interested in how many people are using these little devices and are writing Java Applets for them? I am a little concerned about the lack of security on these devices, as anyone on the network can just write data to the ports to control the IO pins and serial link.
I have brought myself two of the XPort samples, but have been having trouble getting the 'Environmental Control Sample Solution' running. I have to assume someone has this working fine and that I am doing something wrong?
My problem is with getting the Java Applet running (thermostat.java). I can upload the two pre complied cob files (from the CD) to the Xport fine however when I try to open the page http://xx.xx.xx.xx/thermostat.html I just get the applet outline and after about 10 seconds a blank page with nothing else. I can download the thermostat.gif and thermostat.html etc, so i know the cob files are getting uploaded correctly, just the applet does not run.
I have got the GPIO example from Lantronix and have now modified it and uploaded it fine so I know that some java applets work fine. After all the thermostat is the only one I can't get working!
Any ideas?
I have emailed tech support and found this to be not that helpful.
What are designers using their Xports for? I wish to use them for controlling rs232 projects over the network. I was hoping to just add the Xport, but have found now that I need to add some password protection on the RS232 link side as the Xport has just about none. Anyone can write data to any port!!
Having a serial port that can only go upto 230Kbs is a little limiting as well. Would have been nice to have a SPI port or even the ProFibus connected to the outside world. The ProFiBus was 12Mbps!!
