Description
51NET is a ethernet development board, there are 10Mbps Ethernet interface and RS232 serial interface , which uses WINBOND MCU W78E058 processors, including TCP / IP protocol stack and the corresponding application program.To achieve the ARP, ICMP, TCP, UDP protocol, can be applied to HTTP Web server, Mail client, network protocol conversion (such as Ethernet-RS232 interface converter, Ethernet-SPI interface, conversion, etc.), Internet-based remote control,Internet-basedremote data acquisition applications such as embedded networking. There are two board, one is TCP/IP board, another is relay board, you can control relays by Internet.
Hardware Description
(1)CPU using W78E058, the operating frequency up to 40MHz, fully meet the requirements of running multiple network protocols; may also need to replace the CPU for other 8052-compatible microcontroller
(2)HM62256 32Kx8 CMOS static RAM
(3)X5045 , a programmable watchdog timer, 4Kb SPI EEPROM
(4)Multiple LED to indicate operation of the system
(5)The system extends the standard RJ45 Ethernet connector, 3-pin serial RS232 interface, another pins can extend the system .
(6)Power supply: 12VDC
(7)support in-system programming, convenient secondary development
(8)support a variety of common 8052 compatible compiler, such as the Keil C, etc.
TCP / IP stack, RTOS and application software to support independent.
