Series 
Synchronizing Multiple Units 
Up to four DaqScan/2000 Series devices can be synchronized to each other via their rear 
panel SYNC connectors and associated cables.  Each device has two identical SYNC ports; 
either [or both] can be used to connect units.  The DaqScan units can be scan-synchronized 
and triggered from any other SYNC-connected unit.  Note that cables CA-74-1 and CA-74-5 
are 1-foot and 5-foot in length, respectively.  The total combined cable length of the Sync 
cables is not to exceed 15 feet (4.57 m). 
 
Synchronization Concept Block Diagram 
The preceding diagram shows how a DaqScan/2000 Series device can input or output 
synchronization timing and trigger events on either SYNC connector.  A more detailed block 
diagram follows shortly.

Synchronization Model for DaqScan/2000 Series Devices
 (see note) 
 
Note: DaqScan/2002 and DaqScan/2004 have no P1 connector; thus the pin 20  
and pin 25 lines do not apply to those two devices.
