НАЗАДEA1791 ETERE REDUNDANCY SWITCH
24 ноября 2016EA1791 is 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 emit noise or modify the signal to be switched. In addition, the switching is controlled by relays
■Lines are independent from one to another and 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 the event when one of its power supplies is defective
■One EA1791 is required for each playout channel
■EA1791 is the third version of the former ET0558, the device is made in Singapore.
