Taipei, Taiwan, March 15, 2007 – Ethernet Direct introduces BMS-436, a 4-port high speed Serial Device Server, which provides reliable communication connection between RS-232/422/485 serial devices to an Ethernet LAN/WAN. This model is complementing the Ethernet Direct series of Serial Device servers which include BWS-136, BMS-136 and BMS-236 series.The BMS-436 Windows driver installs virtual COM ports in the Device Manager of the operating system. The virtual COM port is designed to establish a connection with the BMS-436. This in turn will allow communications with the connected serial device in the same manner as a device connected to the COM port in a PC.
The LAN becomes transparent to the serial device and the software running on the PC. In addition, BMS-436 also offers a Heart Beat feature to insure a reliable communications connection.
Features
- Industrial DIN rail or Panel mount.
- Supports 10/100 Mbps Ethernet.
- Supports RS-232, RS-422, and RS-485 serial interface.
- Supports LAN and WAN communications.
- In Server mode supports individual client sessions for security.
- Management access password protected.
- Virtual COM drivers for Windows NT/98/ME/2000/XP
- Supports socket connection, TCP server, TCP client, and UDP.
- Supports up to 8 TCP connection in TCP server mode.
- Heart beat connection ensures reliable TCP connection against power failure or network disruption.
- Supports loop back mode.
- Optional 15 DIO, 2 clock/counter input.The BMS-436 can be configured as a TCP Client/Server or UDP and operates in “Direct IP Mode," “Virtual COM Mode," and “Paired Mode."
Data is echoed back for easily testing the connection.
Direct IP Mode
Direct IP connections allow applications using TCP/IP or UDP/IP network socket programs to communicate with the asynchronous serial port on the BMS-136, BMS-236 and BMS-436.
In this type of application the BMS serial server is configured as a TCP or UDP server.
Virtual COM Mode
The Virtual COM mode requires the installation of a virtual COM port device driver.
In this mode, the BMS serial server must be set to either TCP/server or UDP/server with a designated communication port number.
The virtual COM driver is a TCP or UDP client.
Once the connection is made, the LAN is transparent to the serial device.
Paired Mode
Paired mode is also called serial tunneling.
When this type of configuration is selected, no additional software is needed to install in a host PC.
Any two dumb serial devices that can communicate with each other through a serial link will be able to communicate using BMS serial servers and the LAN.
Two BMS serial servers are configured with one set-up as a TCP or UDP client and the other as a TCP/UDP server.
Loop Back
BMS-136, BMS-236 and BMS-436 can also work at Loop back Mode.
All data can be sent back immediately to make the connection testing easy.
Heart Beat
BMS-136, BMS-236 and BMS-436 provide a convenient way to establish reliable communications between two devices.
Communication port 5300 is reserved for the Heart beat Protocol.
If a connection failure occurs, the Heart Beat feature will try to reconnect the TCP data connection every 5 seconds until communications is established again.
Current available Serial Device Server models:
BWS-136 Industrial 1-port serial to Ethernet device server BMS-136 Industrial 1-port High Speed serial to Ethernet device server BMS-236 Industrial 2-port High Speed serial to Ethernet device server BMS-436 Industrial 4-port High Speed serial to Ethernet device server BMS-836, 8 port serial device server will be available soon.
