Professional NTP/LTC Converter
The professional NTP/LTC converter represents the definitive solution for time synchronization in the modern broadcast and audiovisual industry. This advanced device offers bidirectional conversion between NTP, LTC, SMPTE and IRIG-B with millisecond precision, ensuring flawless synchronization in critical applications.
Supported Operating Modes:
- NTP: Synchronization from NTP servers via LAN
- LTC: Linear Timecode (24/25/30 fps)
- SMPTE: SMPTE/EBU standard timecode
- IRIG-B: IRIG-B time format
Main Features:
- NTP Server: Provides network synchronization
- Timecode Generator: Creates LTC/SMPTE from NTP
- Converter: Bidirectional NTP→LTC and LTC→NTP
- GPIO: Interfaces for custom applications
The web interface allows complete configuration: IP addresses, primary/secondary NTP servers, timezone, automatic/manual offset, GPI/GPO for programmable events. The OLED display shows status, IP addresses, configured NTP servers, current date/time and last synchronization.
