NTP to IRIG-B timecode converter

IR-276
NTP to IRIG-B Converter
(NTP Client)


KEY FEATURES DATA SHEET

Overview

The IR-276, NTP to IRIG-B Converter is designed to provide up to 16 customized IRIG-B outputs including 1PPS and NMEA-0183.
The IR-276 is synchronized from a NTP Server and functions as a NTP Client with multiple interface option. Our solution simultaneously supports IRIG-B (Mudulated / Unmodulated), NMEA 0183, 1PPS, and optical 1PPS port.

NTP to IRIG-B converter with 4 x IRIG-B outputs

The IR-276 NTP Client allows the user to assign up to 3 NTP Servers for redundant time synchronization. It selects the best available NTP Server based on criteria such as stratum level, jitter and wander, which ensures that the terminal equipment always remains synchronized to the best available time source. The IR-276 also helps isolate the terminal equipment from the perils of hacking and unlawful intrusions that are possible on an IP network.
