Serial-to-Ethernet Gateway Offers Instant Internet Interface

PRLog (Press Release) - Sep 20, 2007 -
Pittsford, NY:  WIZ100SR is a plug’n’play, extremely reliable gateway module that converts RS-232 protocol into TCP/IP protocol. It enables remote checking, managing and control of devices via Ethernet and TCP/IP by connecting existing RS-232 equipment at up to 230Kbps to a network. WIZ100SR is a protocol converter that automatically converts and transmits data sent by serial equipment to TCP/IP data and converts the received TCP/IP data into serial data for the equipment.

Simple software set-up allows users to rapidly create a 10/100Mbps Ethernet interface with a maximum serial rate of 230Kbps.  WIZ100SR is a compact 2” x 1.2” board with 0.1”-spaced pins that allows any device with serial inputs and outputs to be Ethernet/Internet-enabled for less than $29!  WIZ100SR offers TCP, UDP, IP, ARP, ICMP, IGMP, Ethernet MAC, PPPoE protocols on a 10/100 Base-T auto-detecting Ethernet network.  WIZ100SR ensures excellent stability and reliability since it uses the hardwired TCP/IP stack IC W5100 from Korea’s specialist TCP/IP IC house WIZnet.

WIZ100SR is based on WIZnet’s TCP/IP-offload IC W5100 with built-in Ethernet driver stage. Set-up for WIZ100SR is very easy with the configuration software provided. Three different modes of operation are supported: TCP server, TCP client, and UDP.  TCP guarantees data delivery, but UDP doesn’t require acknowledgement, so communication can be faster.  Once the TCP client and server have established connection, data can be transparently transmitted bi-directionally.  WIZ100SR’s IP Address can be manually assigned (static IP), or IP, subnet and gateway address can be acquired from the DHCP server automatically.  Serial commands can be hardware- or software-triggered.  Configuration can be done on-site if need be, even without a PC, using a simple serial device (keypad, etc.) Power required is 3.3V @ 150mA, but the I/O lines are 5V-compliant, to maintain suitability with older equipment.

An Evaluation/Set-up kit WIZ100SR-EVB provides DB-9 and RJ-45 connectors for quick hook-up, CD (Configuration Program, Schematic, Manual), a 5V 500mA Power Adapter and Serial and UTP cables.

WIZ100SR is available now at $29 (qty 1) from stock at Saelig Co. Inc. www.saelig.com 1-888-7SAELIG from stock   info@saelig.com.  WIZ100SR-EVB Evaluation Kit is also available now at $189.00.
