Word Slock Modul SW:
The module "SW" is the changeover switcher for Word Clock signals in the context of a fail-safe system. The inputs are monitored regarding signal level and frequency. If an input signal is lost or is not present, it automatically switches to the second input signal. How the "SW" reacts to during a changeover can be individually programmed. It can switch (changeover) immediately, at a specific preprogrammed time or can be manually switched.
The following frequencies are monitored:
| Nominal:
|
44,1 and 48 kHz
|
| f x 2
|
88,2 and 96 kHz
|
| f x 4
|
176,4 and 192 kHz
|
The changeover is completed with bistable relays independently for each signal or it can be specified to switch all signals simultaneously. The relay contact remains in its last position if power is lost (such as during the exchange of a module).
The built-in GPI`s can be setup to signal errors. If a RUB IE module is present in the system, SNMP monitoring and web browser configurations are possible. Otherwise configuration is done via a USB connection located on the Rubidium housing and the included 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 via the USB interface of the applicable housing (H1, H3, S1, T1). The firmware and additionally purchased options are setup via this same USB interface.
If the system includes an Ethernet module (RUB IE), a standard web browser can then additionally access the status information and the configuration menus. Monitoring via SNMP is then also possible.
The Rubidium series includes various distribution amplifier modules. The models range from units with four separate amplified outputs, to units designed for maximum security and accuracy with six failsafe amplified outputs, used generally in master redundant systems. The Rubidium series also includes various generators for other signals (LTC, DVITC and ATC) as well as inserters and converters for all these before mentioned signals.
