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
