LANTIME M200 time servers can be installed to provide accurate time
to small and medium sized computer networks.

The M200/WWVB is an economical Time Server that offers all the software features of Meinberg‘s LANTIME platform. It is available in a compact housing as a desktop model, and with an optional accessory kit for rackmount installations. The M200/WWVB includes a precision TCXO and one network interface and is the perfect choice for „Just NTP“ applications in small and medium sized networks.

Quick Network Installation
The M200/WWVB is designed for easy network installation with only a few keystrokes needed on the front panel. A large LC display shows the status of the internal WWVB receiver and the NTP subsystem. Three bicolor LEDs indicate the status of the three main components: WWVB Reference Time, Time Synchronization Service (NTP) and Network (Link status). A fourth ALARM LED can be configured to signal any event that is reported by the notification handling routines.

Power Supply Options:
The M200 has a wide-range power supply that will operate from 100-240 VAC. Optional DC power supplies are available for 10-18 VDC, 19-36 VDC, 36-72 VDC, or 100-240 VDC.

The M200 is the perfect solution where full LANTIME functionality is required in a compact 1U chassis.

The configuration of the system can be done by using a standard web browser for accessing the extensive but straightforward html interface. Alternatively a text based and menu driven setup utility can be started from the shell prompt after logging into the unit via Telnet or SSH.

The security-related features of LANTIME time servers satisfy highest demands. The time synchronization data can be reliably signed and secured by symmetric keys (MD5) and the NTP autokey procedures.

Scope of Supply
Each LANTIME M200/WWVB will be delivered with a MEINBERG 60KHz Antenna mounted in a waterproof plastic case, antenna mounting kit, 20 m (65.6 feet) of RG58 coax cable and power cord with US or European power supply plug.
