LSHM-200

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 -40oC to +85oC 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.
