GPS module V21-1 2/15

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).

How-to Guide
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).
GPS module V21-1 5/15

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“.

How-to Guide
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.

●The power cord separates the system from the power supply. Do not block the power cord, since
it has to be accessible for the users.
●DO NOT use the system if equipment covers or shields are removed.
●If you assume the system is damaged, get it examined by authorized personnel only.
●Adverse environmental conditions are Moisture or high humidity Dust, flammable gases, fumes
or dissolver Thunderstorm or thunderstorm conditions (except assembly PNA) Electrostatic
fields, etc.
●The measurement category can be adjusted depending on module configuration.
●Any other use than described above may damage your system and is attended with dangers like
short-circuiting, fire or electric shocks.
●The whole system must not be changed, rebuilt or opened.
●DO NOT operate damaged equipment: Whenever it is possible that the safety protection features
built into this product have been impaired, either through physical damage, excessive moisture,
