DATA SHEET HEOL-T109: HIGH PERFORMANCE SYNCHRONIZATION UNIT The T109 V2 Time server / Multi-GNSS Clock has been designed to provide very accurate timing information through Ethernet electrical or optical link (using Network Time Security protocol and/or NTP protocol), for Network synchronization and measurement applications, without the need to be connected to external Network, hence preserving your Network insulation. The quad-core ARM Cortex A53, 2GHz processors, allow very high NTP/NTS request rates, up-to 10 000 requests per second. An additional FPGA manages internal Time-management of GNSS...

DATA SHEET A secured HTTPS web server with secure access allows you to configure the HEOL-T109, and monitor its status at a glance (GNSS satellites strength signals, Ethernet connections, alarms, input/outputs…). Users can also monitor and access the T109 settings through ssh. A 2500V isolated event input allows you to time-stamp events from external systems, with ±100 nanoseconds accuracy, refer to UTC atomic clock. The TimeStamp information is reported through RS232, SNMP trap, Email or Broadcast frame. A second event input is available in option. In option, a battery powered internal RTC can...
