Use GPS for Timing and Synchronization

How-to Guide

In the graphic above you see independent measurement systems, synchronised per GPS. Basically

the DEWESoft device needs the PPS (pulse per second) output from the GPS, to correctly synchronize

the AD clock to it. Also a single system can use the GPS time as a timebase for the measurement.

Either internal GPS (DEWE-101, S-BOX) or external GPS (DS-GPS-SYNC) can be used.

This document lists ﬁrst the different GPS (depending if 1 Hz, 20 Hz or 100 Hz option, internal or

external GPS), then the sync port and timing setup is described.

2. GPS settings

If you already have a DEWE-101 (Minitaur) or S-BOX with integrated GPS, you need to check the correct

GPS setting in DEWESoft ﬁrst (should be correctly setup by delivery). Go to Settings -> Hardware setup

-> GPS. Depending on the used GPS type one of the following settings will work:

2.1 1Hz internal GPS

For the 1 Hz GPS option the following Init String must be entered in hardware setup to correctly setup

the PPS output. Enable the checkbox "Send init string", then copy line by line sequentially into the text

ﬁeld.

$PRTHS,U1OP,ALL=0,GGA=1,GSV=1,RMC=1

$PRTHS,PPSG,ENABLE

$PRTHS,PPSO,0,0,500000000

2.2 20 Hz internal GPS

For 20 Hz GPS select the Topcon/Javad device (higher update rates are selectable but cannot be

applied).

2.3 100 Hz internal GPS

Also for 100 Hz GPS select the Topcon/Javad device.

2.4 DS-GPS-SYNC

For the clocking of single slices or a DEWE-43, use the DS-GPS-SYNC kit available at DEWESoft, which

consists of an external GPS (with PPS out functionality), which you just need to connect; all the cabling is

already done.

Connect the Dsub9 to the CAN port, the GPS mouse will be powered from the (often not used) CAN port.

The 00 Lemo cable is connected to the Sync connector for the TTL PPS signal. The serial communication

to the GPS is done over USB by using an additional RS232-to USB converter (included in the set).

Use GPS for Timing and Synchronization

How-to Guide

Install the driver for the RS232-to-USB converter (you can ﬁnd it also on the USB Stick included in the

shipment, in the folder „\Extras\USB-to-Serial_Converter“)

Sometimes it happens that the mouse cursor starts jumping after the GPS is connected (this is

depending on your Windows version); to ﬁx it please follow these steps:

●As soon as the Mouse pointer starts jumping disconnect the DSUB RS232 connection between

the GPS and the USB converter (but do not disconnect the USB converter!)

●Enter the Windows device manager (right-click on Computer, choose “manage” and select

device manager)

●In the list of devices go to “Mice and other pointing devices”, right-click on “Microsoft serial

ballpoint” and choose “deactivate” (do not choose deinstall!)

Then go to the hardware setup and select NMEA compatible GPS, the correct COM port the driver is

using and a baud rate of 4800.

3. Sync port setting

Go to Settings -> Hardware-Setup -> Analog -> and select „DEWESoft USB“; Your DEWESoft device will

be automatically found; the Sync-mode should be set to „Standalone“.

4. Timing setting

Select the „Timing“ tab, choose „DEWESoft USB“ for the timing device and „GPS“ as the time source:

5. Measurement

Exit the Hardware-Setup with OK, go back to Channel Setup – GPS screen and check if the GPS has

found several satellites, shows the coordinates and “PPS sync” is green:

Go to measure mode, the green button on top shows that the synchronisation works ok.

GPS module V21-1 7/15

Use GPS for Timing and Synchronization

How-to Guide

Starting from DEWESoft X2 it is possible to import data from independent measurement

stations into ONE dataﬁle. When the dataﬁles have the same time stamping (synchronised

measurement), you just import and DEWESoft aligns them correctly.

See next chapter for example conﬁgurations.

6. Example conﬁgurations

Directly synching to external GPS is working using 1 Dewesoft device. If you use e.g. 2 separate SIRIUS

slices, synched by sync cable, the sync port is already in use for the internal synchronisation between the

slices. Therefore the DS-CLOCK has to be used to convert the GPS signal to IRIG.

Using the internal GPS of a “multislice” device for timing (SBOX + multiple SIRIUS slices in one

aluminium chassis) works because the connections are done internally.

Calibration

Every instrument needs to be calibrated at regular intervals. The standard norm across nearly every

industry is annual calibration. Before your Dewesoft data acquisition system is delivered, it is calibrated.

Detailed calibration reports for your Dewesoft system can be requested. We retain them for at least one

year, after system delivery.
