5 Failover Switchers - RB-FS42 & RB-FS42DC
at transmitter sites, where a power failure to the unit will not prevent
the audio input signal from being output to each of the supported 4
transmitters.
A row of LEDs on the front panel confirm the unit status, with each
individual program path indicated as being in alarm with either Standby 1
or Standby 2 programs clearly confirmed as actively over-riding the failed
signal. Alarm LEDs on the front panel are also indicated for power supply
1 failure and power supply 2 failure and these are mirrored by the device’s
own General Purpose Outputs so facilitating easy interfacing of the device
with the addition of a summary alarm status GPO.
By monitoring and acting on a GPI Alarm pin for each signal path the unit
can switch between: Through, Standby 1, Standby2 or Silence. The unit will
always attempt to route a Standby path when a Main path alarm is detected
and if both Standby paths are already in use, then one of the two remaining
options (Through, Silence) will be used. The unit can be configured to either
Automatically restore a Main ‘through’ path or wait for a Manual button
press.
In the event of alarm clearing, the unit will automatically revert to normal
operation, but a manual reversion mode is also provided, allowing for
engineering investigation without the unit ‘hunting’ between different
signal paths. Two buttons on the front panel, RESTORE 1 and RESTORE 2,
allow manual restoration of the previously failed signal paths, away from
Standby 1 and Standby 2 respectively.
To facilitate integration with site management systems the RB-FS42
supports SNMP V1 and is configured by a simple web based GUI. All
relevant information regarding input/output status, alarms and power
supplies is available via SNMP GET requests to the unit. Traps can also be
generated for most of the actions which can occur, including power supply
fail and input GPI alarms, etc.
Contact Sonifex for further information if you have a particular requirement
that isn’t catered for by the RB-FS42 as standard.
Category:
Synchronisers, Delays & Silence Detectors.
Product Function:
To route the source audio signals in to a standby
encoder in event of encoder fail. Or to route the destination audio
signals from a standby decoder in event of decoder fail.
Typical Applications:
As a failover switcher for multi channel audio
transport over E1 or IP, typically as performed by APT Oslo, Prodys
Nureus, where a N+1 topology is adopted.
Features:
• Relay based switching.
• Dual DC, or AC, power supplies (select when ordering).
• Encoder site (Set via IP): 4 stereo program inputs, 4 + 2 stereo
program outputs where each program input/Output carries:
analogue L/R, stereo AES/EBU & RS232.
• Encoder site: Each program output has an alarm detect GP
input.
• Decoder Site (Set via IP): 4 +2 stereo program inputs, 4 program
outputs where each program input carries: analogue L/R, stereo
AES/EBU & RS232.
• Decoder Site: Each program input has an alarm detect GP input.
• AES/EBU transparent (for Dolby E transport).
• Passive throughput in event of power outage.
• GPO output for signalling RB-FS42 alarm conditions: PSU 1/2 fail,
Standby 1/2 active, Summary Alarm.
• Automatic or Manual reversion modes.
• LED indicators on front panel.
• IP control, including Web GUI and SNMP.
