ETERE REDUNDANCY SWITCH EA1791

ETERE REDUNDANCY SWITCH EA1791

24 November 2016

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 supplies 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
■EA1791 is the third version of the former ET0558, now made in Singapore.
