H1-Module in a 19"/1 RU-Housing

RUBIDIUM VM Module:

Features

LTCdecoder for MTD
Four built-in amplifiers
Distribution amplifier for serial telegrams
Four RS232 and RS422 interfaces

The VM module amplifies one 10 MHz sinus signal to six individual 10 MHz outputs. In case of a faulty signal output, a seventh amplifier can be switched to one of the six distributing ports.

LEDs located on the front of the module indicate the operating status. Built-in GPIs can be programmed to signal errors or other warnings. The backlit keys on the front of the module can individually be configured with the included software. The setup (configuration) of the module is made using a PC via the USB or Ethernet port (optionally).

Example of a 10 MHz distribution system, 12 outputs

Connection Plan 2

Example of a redundant 10 MHz distribution system, 17 outputs

In order to ensure a fail-safe operation, all signals are analyzed and monitored. In the event of an error, the appropriate output is switched to the reserve amplifier. The changeover is programmable as follows:

Immediately (automatically)

At a specified time (automatically)

Manually (by pushing one of the programmable keys)

Available functions can be selected by configuration over the housing’s USB interface. If a RUB IE Ethernet module is on hand, configuration can also be made via a standard web browser.

A status monitor can be accessed at any time. SNMP is available in combination with an IE modul.
