Functional Description and Specifications RUB VM Page 10 1.5 Software Update Software updates require a (windows operating system) computer and the “RUBIDIUM CONFIGURATION“ program. You can download the latest version of the program from: https://www.plurainc.com. Please check the PC connector at your RUBIDIUM housing: There is an USB or RS232 (with a DSUB9 connector) interface installed.
Functional Description and Specifications RUB VM Page 11 Operating Description 2.1 Functional Overview The basic functions are: • Continuous wave distribution: One input to six outputs. • Input and output monitoring. SPARE OUT Changeover OUT 1 Changeover OUT 2 Changeover...
Functional Description and Specifications RUB VM Page 12 2.2 Monitoring and Status Information This module monitors the signals at the seven output stages with respect to frequency and minimum amplitude (see chapter “Specifications” as well). An error detected at the spare output could be considered as an error of the signal input.

Functional Description and Specifications RUB VM Page 13 Signal status during normal operation: status: Informs about the current status of each output stage: ‘ok’ or ‘fail’. • ‘fail’ at spare output stage: Signal failure for one second or more. •...
Functional Description and Specifications RUB VM Page 14 2.3 Signal Changeover With the default set-up (“Factory Settings”), the changeover relays operate in the automatic mode. After the power has turned on all the relays have their contacts open. Utilizing the Distribution function with one of the configuration tools, you can switch between automatic and manual changeover.
Functional Description and Specifications RUB VM Page 15 2.4 Errors and Alarms Overview Each output stage has its own status, error counter, alarm counter, GPI output, and SNMP trap functionality. GPI_1 to GPI_6 are assigned to output stages 1 to 6, GPI_7 is assigned to the spare output (or input).
Page 16
Functional Description and Specifications RUB VM Page 16 Alarms Each output stage has its individual alarm counter and GPI output. Any error will become an alarm if the corresponding GPI is enabled. Each GPI can individually be enabled or disabled by configuration.

Functional Description and Specifications RUB VM Page 17 System Failure Check the “System Failure“ checkbox Active, as long as the “total number of alarms” counter has a count value > 0. This trap feature becomes active in any event of those errors which simultaneously raise a GPI alarm, i.e.
Functional Description and Specifications RUB VM Page 18 Status Monitor 3.1 Status Monitor by the IE Module The RUBIDIUM SERIES HTTP server, located in the RUB IE module, offers a status monitor. Please refer to the “Functional Descriptions and Specifications IE” manual for a detailed description of how to access the RUBIDIUM SERIES system and how to open the RUBIDIUM homepage.
Functional Description and Specifications RUB VM Page 19 3.2 Status Monitor by a PC Program The PC program RubStatSE.exe uses the PC interface (RS232 or USB) of the RUBIDIUM housing. This program is part of the “Rubidium Series, config software” packet you can download at: https://www.plurainc.com.
Functional Description and Specifications RUB VM Page 20 3.3 System Status This module monitors the signals at the seven output stages with respect to frequency and minimum amplitude. The status monitor informs about the state of each output stage and about the state of the...
Page 21
Functional Description and Specifications RUB VM Page 21 System Set-up reflects the current set-up as selected by a configuration tool: set-up ‘OK’ or ‘failure’. This is the result of the power-on check. In case of a failure all settings have been reset to the default values automatically.
Functional Description and Specifications RUB VM Page 22 3.4 Status of Fan and Power Supplies This module – as all configurable RUBIDIUM modules – is able to monitor the fan and power supplies which are plugged to the same housing as “VM”.
Functional Description and Specifications RUB VM Page 23 The Rubidium Configuration Tools 4.1 The Rubidium Configuration PC Program Please refer to the “Installation & Systems Manual RUBIDIUM SERIES” for a general description of this program and how to install it. In this document please notice the following subchapters: •...
Functional Description and Specifications RUB VM Page 24 4.2 The Rubidium Series HTTP Server The RUBIDIUM SERIES HTTP server is located in the RUB IE module. A 10/100Base-T Ethernet connection and a web browser allow access to the RUBIDIUM system.
Functional Description and Specifications RUB VM Page 25 4.3 “Functions“ Click on Functions to see all applicable tabs/pages listed, and to activate or deactivate tabs/pages. For example (screen shot of the PC program tab): A tab/page reflects a function of the module. The columns Edit and Use determine whether the function in the module is activated/deactivated and whether user configuration of that specific function is allowed or not.
Functional Description and Specifications RUB VM Page 26 4.4 “Keys“: Keys, Lamps and LEDs RUB1 modules have four illuminated buttons (keys and lamps) and four LEDs (Light Emitting Diodes). Basically, the functions of these in- and outputs are programmable. Some functions presented by the configuration tool maybe assigned to special options, and therefore are not applicable with the standard firmware.
