Trimble Outdoors AcutimeTM2000 Synchronization Kit manual 0x8F-0B, Comprehensive Time

A Trimble Standard Interface Protocol

0x8F-0B

Report Packet 8F-0B

Comprehensive Time

The output of the packet is synchronized with the PPS, and may also be generated in response to external events. Report packet 8F-0B provides easy identification of each timing pulse and contains all the information required for most timing and synchronization applications. Output of this packet can be disabled and configured using the 8E-A5 packet on Port 1. If output of the 8F-AD packet is also enabled, the 8F-0B packet will always be output after the 8F-AD packet. The packet contains 74 bytes in the following order:
