Acutime 2000 Synchronization Kit User Guide A-103
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:
