Ethernet Direct Introduces BMM-101 Single Port Modbus Gateway

Taipei, Taiwan, 31 August, 2007- Ethernet Direct Corporation, a professional and primary provider of Industrial Networking and communication solutions, is glad to introduce BMM-101, a single port Modbus gateway to provide Modbus communication between Ethernet and serial Modbus devices.

Modbus is one of the most popular industrial control and data acquisition protocol. Considering the different between Modbus TCP (Ethernet) and Modbus ASCII/RTU (Serial), Ethernet Direct new solution BMM-101 is ideal for the integration of Modbus Ethernet and serial devices. By deploying BMM-101, Modbus serial slave devices can be seamlessly incorporated into an existing Modbus TCP network and Modbus TCP slaves can be made accessible to serial masters compatible with almost any Modbus network.

Features of BMM-101

Installation either by DIN rail or Panel mount supportable

Supports 10/100 Mbps Ethernet

Supports RS-232, RS-422, and RS-485 serial interface

Supports LAN and WAN communications.

Management access password protected

Supports up to 8 MODBUS TCP master to MODBUS RTU/ASCII

Supports MODBUS RTU/ASCII master to link up to 8 MODBUS TCP clients.

Supports inactive timeout to shutdown connection for allowing accepting next connection

Supports loop back mode. Data is echoed back for easily testing the connection

Hassle Free Configuration

Ethernet Direct understands the need for user friendly configuration tools when it comes to application requirements. BMM-101 is designed with user friendly management software which provides an easy way to configure BMM-101. This software would be able to search devices within a local area network independent of its subnet. It can also locate a device with a specific IP address over wide area network. BMM-101 can also be configured by its console port or through telnet connection and also comes with WEB interface for easy configuration.

In order to make connection testing easy, BMM-101 works at Loop back Mode in which all data is sent back immediately.
