RTC DONGLEReal Time Clock Serial Interface DongleThe Barix RTC Dongle is a real time clock devicefor the RS-232 serial interface. It allows for time-based applications such as scheduling, datalogging and automation on stand alone devices,as well as networked devices in environmentswith no NTP server or Internet connection.The Barix RTC Dongle can be attached toany Barix product that has an RS-232 serialinterface, such as devices of the Annuncicom,Exstreamer, Instreamer and Barionet productfamilies and is supported by applicationslike the FTP-MP3 store and forward and theBarionet standard firmware. Furthermore the RTCDongle can be attached to a non Barix device aslong as it features a standard RS-232 serial inter-face and is programmable.A plastic strip prevents the built-in batteries fromdischarging while in stock. The strip must beremoved prior to installation to power the RTCDongle. From that point the built-in batteriesguarantee 3 years of back-up operation. Thisperiod is extended when the connected device isswitched on, powering the RTC via RS-232.For programming custom applications, the RTCsupports the following command functions:- setting and reading the time and date- setting and reading the clock‘s fine adjustment- switching on and off the LED- detecting the presence of the RTC- reading the RTC firmware versionApplications• Scheduling• Data logging• AutomationSupported Barix Software• ABCL Kit firmware• Barionet standard firmware• Store & Forward FTP-MP3 player firmware
