Search Tips...

Keyword Search
Our search engine uses any or all keywords typed in the text box to give you product search results.
For instance, typing in kvm will give you a broader set of results than kvm switch cables.

Note, however, that keywords in quotes are treated as a single phrase and will not be evaluated individually.

Booleans (AND, +, OR, NOT, -) are not supported.

Also, some keywords will not return results, and may automatically correct to a similar keyword.

Part Number Search Selection
Select this Search in the drop down box to search by part number instead of keywords.

Wild Card Search
The * character is only supported in a limited capacity. Using whole words is the best approach whenever possible.

"New Search" Radio Button
Search the entire section that you are currently in.

"Search Within Results" Radio Button
Enter keywords or a part number to limit your results within the previously searched results.


Other features

A list of all matching product categories or resources will appear in the upper left corner of the results page, when applicable, to help you further narrow your results, if you desire.

Use the "sort by" drop-down menu on the results page to sort by "most popular" and price (low to high or high to low)
in the store section.

    2-Port 10/100 Device Server, RS-232/422/485, DB9 M


    Quick Facts

  • An easy way to remotely monitor, manage, and control your industrial devices in the field.
  • Easy to configure through a Web browser, serial console, Telnet™, or Windows® utility.
  • Very compact.
  • Accepts 12-VDC power. Order the 100–240-VAC/12-VDC power supply (PS012B) separately or order this device server together with a power supply as a kit (LES302A-KIT).

    • Further Details

  • Features TCP server/client, UDP, virtual COM, and tunneling modes.
  • Software-selectable RS-232/485/422 serial data communications.
  • Ideal for controlling manufacturing or automation devices over a LAN.
  • Auto MDI/MDI-X Ethernet port. Autonegotiates, autodetects for 10 or 100 Mbps.
  • Rugged, metal case that can be wall or DIN rail mounted (mounts included).
  • Firmware can be upgraded over an Ethernet network from a remote PC.
  • On serial side, features 15-kV ESD protection.

    Use your Ethernet network to reliably access remote RS-232 devices or RS-422/-485 industrial equipment from a remote workstation.

    The 2-Port 10/100 Device Server gives you a cost-effective gateway for TCP/IP Ethernet and serial signal communications, enabling nearly any serial devices to be connected to a new or existing Ethernet network.

    It does this by encapsulating serial data and transporting it over Ethernet, communicating full-duplex and transmitting bidirectional data transparently between the serial port and a network.

    Plus, it’s easy to configure. You can do this remotely over the Ethernet link using Telnet, a Web browser link, a serial console, or another Windows utility.

    Even better, it comes with virtual communications software. Through it, you can use an existing Windows based application to access a serial device by mapping the virtual COM port to a remote serial server over Ethernet.

    In addition, the device server supports TCP server, TCP client, and UDP modes of communication, and serial tunneling, which you can use to send data between two serial devices via the TCP/IP link instead of RS-232, -485, or -422 connections. Link a touchscreen to a distant PLC over the Ethernet network, for instance. (NOTE: Multiple units needed for TCP client and tunneling modes.)

    Ideal for any manufacturing, process engineering, or automation application, the 1-Port 10/100 Device Server, RS-232/422/485 can also be used to communicate with bar-code scanners, terminals, PLCs, electronic Kanban inventory management devices, and similar equipment on the factory floor.
