The
ET-WEB51 TCP/IP Ethernet Web Control Board comes preloaded with TCP/IP
software that allows you to control outputs, sense inputs and write
text to an LCD. All this across the Internet via a standard browser.
As a value-added bonus a matching port of the world's premier embedded
TCP/IP CGI webserver software is included at no additional cost. Written
in well documented C code, uIP v0.9 will allow you to write your own
dynamic embedded webpages, as well as to experiment with other protocols
such as FTP, SMTP, TELNET, Webclient, etc. This is a super value package
for those wishing to program their own applications with the TCP/IP
protocol suite.
ET
have produced a remarkable board in the WEB51. It is based on the popular
Atmel AT89C51RD2 microcontroller, and features the RealTek RTL8019AS
full-duplex ethernet controller chip. You get a huge 64K In-System-Programmable
FLASH memory for code and web content, backed up by up to a further
4 optional, I2C addressable EEPROM memory chips. There is space onboard
for a battery backed DS1307 real time clock chip, as well as options
to expand the standard RS232 communication channel for RS485/RS422 communication.
