Lantronix MSS100 Device Server



MSS100 External Device Server

  • DB25 serial port with full modem controls and speeds up to 230 Kbps
  • EZWebCon and COM Port Redirector software included for easy configuration and control
  • 10/100Base-T Ethernet

Remotely Monitor, Manage and Control Equipment Over Ethernet

The MSS100 is a fast, easy way to connect virtually any device with a serial port to a network, so it can be managed remotely. The MSS100 enables you to operate and manage RS-232 serial devices over the LAN, WAN or Internet and replace dedicated PCs and lengthy serial cables with fast and reliable networking technology. This remote access capability increases efficiency, saving you time and money while providing easier management from any browser  anywhere, at any time.

Featuring a 32-bit processor, feature-rich operating system, high-speed serial interface and 10/100 Ethernet port, the MSS100 provides the performance needed for demanding and multi-tasking operations such as:

  • Retail Point-of-Sale
  • Medical Instrumentation
  • Building Automation
  • Security Systems
  • Manufacturing/Industrial Automation

COM-based Application Control Over Ethernet

The included COM Port Redirector software enables Windows applications designed to only communicate though local COM ports to now communicate over to network-enabled devices over Ethernet. The software creates virtual COM ports which are mapped to remotely networked MSS100 units connected to your equipment. This enables you to extend the reach of your devices software applications across the globe.

Total COM Port Control

MSS100 includes additional added functionality of complete COM port control when using COM Port Redirector. All hardware pins on the MSS100 can be set and read by the application that opens a "Redirector" COM port. This enables applications that require total COM port functionality to be extended across the network.

Easy to Set Up and Use

The MSS100 can be set up locally through its serial port, or remotely using Telnet or a web browser. The included EZWebCon Windows-based configuration software simplifies setup and enables users to easily configure and monitor the MSS100 activity through on-screen menus instead of entering commands at the local prompt.

RoHS-compliant, the MSS100 meets Directive 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment.
