Trimble Outdoors AcutimeTM2000 Synchronization Kit manual Event Input, Primary Port Features

A Trimble Standard Interface Protocol

For systems with minimal bandwidth for processing serial data streams, the receivers can be configured as silent devices, which only generate I/O when polled. On the other end of the spectrum, the Ace UTC and Acutime 2000 receivers can be configured to output various automatic report packets and protocols to satisfy demanding real-time update requirements of complex monitoring systems.

Event Input

Both receivers feature an event input which can capture and report time stamps with the same precision as the PPS signal.

Primary Port Features

The Acutime 2000 and Ace UTC both feature a primary bi- directional port, which is factory configured as for TSIP input and output.

Secondary Port Features (Acutime 2000)

The Acutime 2000 has a bi-directional, programmable secondary port, that is designated as the Timing port. The timing port’s protocol input lines are shared with the Event input feature.

The receiver can be configured to accept protocol input or event signals, but not both. Acutime 2000 cannot generate event time tags if port A is configured for RTCM input or TSIP input.

The port can be configured to accept and output data using various protocols as shown in the table below.
