ETERE REDUNDANCY SWITCH EA1791

ETERE REDUNDANCY SWITCH EA1791

01 February 2015

A redundancy component to switch the control of devices between main/backup controllers, devices can be connected via GPI or Serial.

The EA1791 is a redundancy switch that enables the switch of multiple main/backup devices, whether controlled via serial (e.g. RS-232 and RS-422) or via GPI.



    ■ The device is based on relay switching so its connections are fully bidirectional

    ■ Etere Redundancy Switch does not make any noise or modify the signal to be switched and the switching is relay controlled

    ■ Lines are independent from one to another, any protocol can be used

    ■ The switching can be manual from the front panel, via a remote controlled GPI or by Etere Automation

    ■ Use of two power supply for redundancy

    ■ When used with Etere Automation, EA1791 sends SNMP error traps in case one of its power supplies is defective

    ■ One EA1791 is required for each playout channel
