Notice:

1. The interval of 1PPS pulse must be controlled within 1s ±100μs;
2. In GPRMC message, the status bit (<12>Mode>) must be A, otherwise, synchronization
timing cannot be given;
3. The different GPS module could send out different GPRMC message length, the RS-Ruby
Lite could be compatible with the most GPS modules on the market. Please contact
RoboSense of technical support when it is incompatible.

6.2 Precision Time Protocol (PTP)

6.2.1 Principle of PTP

PTP (Precision Time Protocol) defines a protocol enabling precise synchronization of clocks in
measurement and control systems, also used in different devices. Compared with other
synchronization mechanisms, PTP has many advantages:
1) In comparison with NTP (Network Time Protocol), PTP could meet much higher demand of
time synchronization. NTP could only satisfy the sub-second-level synchronization. However,
the synchronization accuracy of PTP is sub-microsecond.
2) In comparison with GPS (Global Positioning System), the cost of purchase and
maintenance of PTP is much lower.

6.2.2 Topology of PTP

The setup steps of PTP:

1)In web application, the PTP Mode should be chosen (referring to A.2 Web configuration);
2)Prepare a PTP Master ;
3)Ethernet Switch;
4)The device supporting PTP.
5)The Topology is shown as below:
