Embedded Serial-to-Ethernet Modules
 

LSHM-200 (Or LSDM8300SM for new design)		LSDB-200

Measuring only 1” (W) x 1” (D) x 0.25” (H), the LSHM-200 family of Embedded Serial-to-Ethernet Modules connect serial devices to IP networks with a 10/100BaseT interface.  They provide an easy solution for connecting micro controller based systems with serial port to IP networks for remote control, and monitoring applications.

The LSHM-200 family allows for seamless access and communications of serial data through any 10/100BaseT Ethernet.  They can transfer data among multiple IP addresses simultaneously via Telnet ports with TCP/IP protocols under Ethernet.  The onboard Ethernet functions are designed to meet IEEE std 802.3™ with automation and buffering.  The integrated serial port includes standard serial terminal features such as flow control and standard 8-N-1character lengths.

The serial interface of LSHM-200 family supports DTE speeds up to 230K bps.  The LSHM-200 family features -40^oC to +85^oC operating temperature and are RoHS compliant.

There are two models available, LSHM-200 and LSHM-201.  The LSHM-200 includes 2-channel DMA and a 7-bit 2-channel ADC while the LSHM-201 has a 4-channel DMA and an 8-bit 8-channel ADC built in.  The LSHM-201 includes external Flash memory allowing for updating firmware with the latest enhancement or implementing firmware changes for custom applications.

The Development Kit LSDK-2001 and LSDK-2011 are designed for engineer's testing, programming and evaluation convenience.  Each kit includes an LSHM-200 or LSHM-201 mounted on our carrier board with all needed connectors, power adapter and cable accessories.

Features:

• Compact size - 1" x 1" x 0.25" (H)

• -40^oC to +85^oC operating temperature

• Serial TTL interface

• 10/100BaseT network interface, auto-detect

• 10MB or 100MB data transfer rate configurable

•  Designed to meet IEEE std 802.3™

• Complete Serial-to-Ethernet connectivity solution including:
  Network Processor, Mac and PHY interface

• Support of TCP/IP, UDP, Telnet, HTTP, ICMP and ARP

• DHCP and static IP support

• LED pins out for monitoring Ethernet and link activity

• Built-in 32K SRAM for Ethernet buffering

• NVRAM for storage of configurations

• External flash memory (LSHM-201 only)

• DTE data speed up to 230K bps

• Hardware and software flow control
