Post by thread:[PIC] Using Lantronix XPorts

I'm about to try to integrate the Lantronix XPort connector to an 18F252 for ethernet capability. To start with it will be talking with PC's using ethernet cards. >From what I understand I simply set up the XPort as a transmitter and then the receiving end should be able to get my serial data. The process is referred to as serial tunnelling. Is it really that easy or is something waiting to put egg on my face when I try to make a guesstimate on how long it will take to deliver this feature? If anyone else has experience with these I would appreciate some feedback. Regards, Andy

I have one sitting here for some months now, but haven't had the time to experiment with it. So I'd love to hear your experience with it. In my case, I am planning to use it as a web server, where the PIC app will configure output data in the form of web pages and the PC will just read the data. Cheers, -Neil.

Yep, I've used them as a serial to ethernet converter and it pretty much is that easy (sending and receiving). You do need a fairly hefty supply for the XPort (220mA @ 3.3V from memory). XPort can configured in a web browser. In operation I like using a utility program called HW Virtual Serial Port which sets up a virtual COM port on your PC to the XPort at a given IP address : port number.

I've always thought stuff like the Xport should have a way of letting the micro behave like a cgi script. When an http get command shows up, pass the whole url (or maybe the part after the hostname or ip) to the micro as a string. The micro can then parse the url pulling out any parameters and respond with an html page (including headers). Xport and the like seem to try to do too much and leave little flexibility to the micro.

I've been using them with PIC18 series for several years now. I think they are the greatest thing since sliced bread. The new ones have a MUCH higher serial bandwidth. I can't get an answer from them on what buffering they have internally. But with an average data rate at 56K, it seems to be fine. (I have been aassured they work to 2M, in burst mode.)
