The sync connectors are required when you want to use multiple SIRIUS® USB slices for the same                 

measurement. The signal that is transferred over this cable makes sure that the measurement data of                

the different slices are perfectly synchronized to each other. 

Sync connectors have 2 use-cases: 



● SBOX: When you have an SBOX with GPS option, you can use the SBOX as a clock master. In this                    

case the SBOX will use the GPS signal to generate the synchronization signal for the attached                

measurement modules: e.g. the SIRIUS-SBOXe has one sync connector at the front. 

● SIRIUS® USB slices: When there are 2 connectors it's easy to chain several SIRIUS® chassis (or                

DEWE-43, DS-CAN2, etc.) together. 

Note that there is no distinction between the IN and OUT – it does not matter which connector                  

Important 

When IRIG-synchronisation is used, the IRIG differential signals are on pins 1, 2. 

When Clock / Trigger is used, the signals are on pins 1, 2. 

When PPS-GPS synchronization is used, the PPS signal is on pin 3.  
