I haven’t really been reading lately… is thereanything new and cheap for putting PICs on Ethernet? S7600 is out, .. andEmbeddedEthernet has that $70 chip, but I was hoping to keep the cost under 50$for the couple devices I am working on. I would prefer to pour a little moresweet into a job than money.  I prefer 18Fx52, and I was hoping for features like telnet,but basic ---Links-Are-Forbidden--- server or even just somewhere to start like UDP would be nice.  Charles

www.rabbit3300.com says from $32.00 at 1000 qty for RCM3700 with

Flash and SRAM in advertisement. I have not been to website. I saw

another company advertising $45.00 single price in fat RJ-45 jack

without bells and whistles, but I do not recall who.

while I agree that this is a clever idea - using an ISA network card,

it seems like it would be awfully big (physically). Guess thats the

trade-off. I'd much rather have a compact way of getting onto the

network.



I'm probably the only guy who thinks this is kind of an odd grand

prize winner for the contest. I mean, recycling 10 year old

technology... Maybe I just dont understand the beauty of it.

It was a year 2,000 contest. Remember the year they celebrated the

new milenium a year early ?



back in 'those days' pretty much anything was new.



But, as I read it, (couldn't find any of the contest rules or what

the full thing was) it may be that this board fit into a hard drive

case on a slot and was a server?. If that was the case, then the fit

was probably pretty good.



I did figure out that the prize was not for who could come up with

some way to use old cards (other than making a clock)

I use a Lantronix XPort to put PICs on the 'net. Built-in telnet, Web

server and email

client. The best part is that it offloads the PIC from all the tcp/ip stack

stuff.

I've always thought that the xport looked attractive - both from a

size and functionality perspective. However, every time I've asked

about it (ok, twice), I've gotten pretty negative feedback on the

company (not the product).



What was your experience with the xport? What's a reasonable

expectation for transfer rate? Any gotchas?

I have to admit, sometimes you have to dig for information - but



The product is solid. It runs to at least 115Kbaud - newer versions promise

approx

900kbits/sec.

No "gotchas" that I can think of, but a few points of interest:



You can set up the unit either through the RS-232 port, or through the

(password-protected and disable-able) net port. If you configure through the

serial

port using a PIC, you need to use their special "setup record" format.

Normal setup

is using a terminal, but Lantronix does not guarantee that the questionnaire

screens

will remain the same, so parsing the responses and sending commands are not

"safe" ways to build a product. They do guarantee the consistency of the

Setup Record format

so that is the correct way to setup the unit using a PIC. The setup record

is

simply a Hex file you dump in pretty much blindly.



One other thing: XPORTs are 3.3V devices, and consume about 120mA. I use a

low-

dropout regulator to power them from the PIC's 5V Vcc and an HCT125 to

level-shift "upwards"

between the XPORT outputs and the PIC inputs, and 1K protection resistors

between the 5V PIC outputs and the

3.3V XPORT inputs. I also use that same HCT125 to multiplex the RS-232 data

between the XPORT and

a MAX 232.



As long as a telnet session is in progress, it comandeers the RS-232 port.

With no session in progress,

the RS-232 port works normally. The PIC can also force control away from

either port.

Thanks Chad,



I looked into that device, looks clever but I wasn't interested in

the SLIP connection, I was hoping to go straight to ethernet no PC

or other hardware inbetween



I think the Lantronix solution is probably the best bet because I am

mostly interested in having the PIC work as a telnet client with

that "18F452 Dumb Terminal" project I made last year. It runs on RS-

232 fine, but I want to build one that works on ethernet.

I did not read it through, and to be honest, I have not really gotten

into the whole TCP/IP physical or logic layers much other than the bare

basics.



I wish I saved the article, but a while back some guy built up an

interface to turn his basement lights on and off over the internet for

something like $20. He was going to put them all over his house for

the coffee pot and whatever. Do not think it was a PIC, but was simple

and cheap.

That would be neat trick, but I don't think my wife will let me go

about playing in her toaster and coffee pot and such, I already have

a seriously lagging "honey do" list..



I once researched a nice project using yet another ISA NIC card

which seemed easy to do (3COM Card)... but some of the links were

dead so I couldn't really get much info off it, that was back when I

was looking for the information on sending text through a ISA VGA

card to a monitor in 80x25 mode.. I got all the info on that, just

never finished the project. I probably try to push my PICs to hard,

but I don't really want to start using ARMs or other faster

controllers, I don't have a use for them in any business application

so it'd be a waste of my time.

Are you saying that a siteplayer can serve a live camera image? If

so, how do you connect a camera output (I assume NTSC) to the

siteplayer? I am very interested in this since I am working on a web-

controlled robotic camera. I was assuming that I would need a mini-

ITX board to have enough horsepower to serve a live camera image.

Hey, thanks for the write up you posted. Very useful. I noticed

their web site said 5V tolerant, is that a newer version than the one

you used or it that classical marketing speak for "if you do a lot of

work"?



Anyway, I have a project that needs a remote connection and the

client has wifi in his sites so I though the xport into a bridge may

just work. The client had been thinking something really heavy-

weight to basically flip a switch so this looks like a very

reasonable solution. Any experience with xport and wifi bridges?



Thanks again for your posting, I really appreciate it.
