Stellaris串口转以太网参考设计套件(RDK-S2E)提供了完整的, 开放工具, 从准备到实施的解决方案，用于添加任何串行设备的网络连接.Included in the RDK-S2E is the tiny-footprint Luminary Micro Stellaris Serial-to-Ethernet Module (MDL-S2E). The most common application for the MDL-S2E is for augmenting legacy products that only contain a serial port for a configuration or control interface. In addition, newer computers, especially laptop computers, do not necessarily have serial ports, and a serial connection is limited by cable length (typically 10 m). Simply installing a Stellaris Serial-to-Ethernet Module into the legacy serial device provides many benefits including no major board redesign or software changes, easy sharing on a network other than Ethernet, tiny form-factor for unobtrusive implementation, and 10-meter maximum cable length for serial connections is no longer a limitation.
特性
The MDL-S2E is the first serial-to-Ethernet converter available with a highly integrated Cortex?-M3 microcontroller with 50 MHz of performance and ample single-cycle, on-chip Flash and SRAM memory for efficient network traffic handling. For maximum space savings, the Stellaris microcontroller is offered in a small BGA package and integrates the 10/100 Ethernet MAC and PHY on-chip.The RDK-S2E ships with the MDL-S2E module. The MDL-S2E is a ready-for-production serial-to-Ethernet module with the following features:
LM3S6432 in a 10 x 10 mm BGA package for reduced board size
10/100 Mbit Ethernet port
Auto MDI/MDIX cross-over correction
Traffic and link indicators Serial ports
UART ports include RTS/CTS for flow control
UART0 has RS232 levels, transceiver runs at up to 230.4 Kbaud
UART1 has CMOS/TTL levels, can run at 1.0 Mbaud
Software
IP configuration with static IP address or DHCP
Telnet server for access to serial port (VCP software included)
Web server for module configuration
UDP responder for device discovery
Telnet client for Ethernet-based serial port extender
Module supports 5 V and 3.3 V supplies
Multiple mounting options
JTAG port pads for factory programming
套件内容
While the MDL-S2E is ready out-of-the-box for immediate integration in a system, complete software source files are included for simplified customization.
