LTC / RS 485 changeover unit and monitoring module.
- Switcher for LTC signals
- Signal monitor with status indicator
- GPI outputs for error indication
- Optional SNMP and status indication via an internet browser
- Bi-stable signal outputs relays
The PLURA "SL"module is an automatic switchover unit for LTC signals. It monitors and analyzes two LTTC sources. If a LTC source is lost, the LTC output is automatically switched to the other error free source. Connected with a reference time source, the LTC signal is monitored and analysed in conjunction with this reference time signal.
The module can monitor the following:
- Errors in the LTC
- Errors in the reference time source,
- Time differences between the two individual LTC sources
- Status information of all input sources.
If an Ethernet module is present in the system, the status and error messages can be queried via a browser or SNMP. When combined with two of PLURA master generators RUB "GT", a fully redundant fail-safe LTC generator system is possible. One or both VITC input sources can be acquired from any third party devices as long as the LTC signal complies with the SMPTE/EBU specifications.
In the event of a failure the signals can be switched autmatically or manually. The changeover is completed with bistable relays. The relay contact remains in its last position even if power is lost. The relays are mounted on a separately installed circuit board, so that even when physically exchanging a module the signal flow can continue without interruption.
LEDs located on the front of the module indicate the operating status. Built-in GPIs can be programmed to signal errors or other pre-programmed warnings. The backlit keys on the front of the module can be programmed to suit the user specific needs (e.g. a key could be programmed to manually switch incoming sources).
Distribution amplifiers modules with four separate outputs as well as six fail-safe amplified outputs can be utilized for redundant systems. The Rubidium series can offer various generators, inserters and converters for different signal formats (LTC, DVITC and ATC).
All programmable functions and the communication between modules can be set with the included configuration software. The operating status of the module is available at any time via a status monitor function. The status request is made using a PC software using the USB interface of the applicable housing (H1, H3, S1, T1). Firmware upgdate for the frame and other modules can be set up via the same USB interface. With the optional Ethernet module (RUB IE), Standard web browser can utilized for all status information and configuration menus. Monitoring via SNMP is also possible.
