Figure 8 RS-Helios-16P Different Phase Settings
Using the RS-Helios-16P Web Interface, users can check and modify the Phase Locking settings,
click Setting > Phase Lock Setting, for the "Phase Lock" parameter setting. The phase locking value
can be set from 0 to 359.
5.6 Time Synchronization
RS-Helios-16P supports GPS+PPS and PTP time synchronization methods. Users can use the RS-
Helios-16P Web Interface to set the time synchronization modes. (Please refer to Appendix A.2 for
detailed instructions of setting by using Web Interface.)
RS-Helios-16P can be connected to an external GPS module and can synchronize the sensor system
time with the time provided by the GPS.
5.6.1 GPS Time Synchronization
Figure 9 GPS Time Synchronization Timing Diagram
The GPS module continuously sends GPRMC message and PPS synchronization pulse signals to the
sensor. The PPS synchronization pulse width is from 20ms to 200ms, and the GPRMC message must
be sent within 500ms after the rising edge of the PPS synchronization pulse.
5.6.2 The Use of GPS for Time Synchronization
The GPS_REC interface in the Interface Box of the RS-Helios-16P follows the RS232 level standard,
as shown in the table below:
Reset part of sub-second
According to GPRMC message, synchronize the part of second
