Introducing the ENTA-R, a ruggedized version of Brandywine’s popular ENTA II, this unit is capable of delivering HaveQuick + 1PPS to a multitude of outputs. The ENTA-R is a full function Master Clock that is designed to provide a full suite of Have Quick time code and 1PPS outputs, as well as NTP, fully compliant with NENA requirements for a Master Clock.

The ENTA-R provides four single-ended outputs that are either Have Quick or 1PPS, as well as 12 differential outputs via RS422.

The unit uses dual hot-swappable power supplies for high-reliability operation. A built-in web server provides user-friendly controls for configuring the unit. All outputs include signal level monitors to enable rapid fault-detection and isolation.
