ASI Redundancy Switch, 2 or 6

Part Number:



The RSS2-ASI/RSS6-ASI station incorporates (2 or 6) Automatic A/B switches to monitor independently digital Video feeds in DVB-ASI or SDI format, with automatic switchover to their respective backup feeds. The threshold level at which the unit switches to the backup feed can be separately adjusted for each input and automatic switch module in the chassis.

The RSS-2ASI/RSS-6ASI offers high isolation environment between input ASI feeds and minimal insertion loss. Input & switch status indications are available at the front panel, with toggle for switch override & control.

Ethernet/IP & RS-232 ports are available at the back of the chassis for remote monitoring, alarm & control. While the SNMP protocol is used for alarming to and remote monitor/control by NOC “Network Operation Center” over the IP-Network, an embedded Web-Server allows regional & local technical personal to remotely access (password protected) for status monitoring and switch override/control from a Web-page using any standard Web browser. The Serial port is used with an external modem to override/control the switch by DTMF (phone) switch control commands over telephone dial-up line.


  • Fail-safe during power loss: When power loss occurs, the RSS-2ASI/RSS-6ASI switches back or remain in the primary position to pass the main input ASI/SDI feed.
  • Threshold adjustment: Separate front panel adjusting pot available for each input.
  • Hysteresis: 2-3dB built-in Hysteresis to prevent flutter during automatic switching.
  • Switch delay: An optional fixed delay can be added, before automatic switching to the backup input, after the RF dropped below the threshold level setting.
