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.
Reference Notes:
¾ The SYNC features are programmable via software. For detailed information
see the Using Multiple Devices and the daqAdcSetClockSource sections of the
Programmer’s Manual (p/n 1008-0901).
¾ During software installation, Adobe ® PDF versions of user manuals
automatically install onto your hard drive as a part of product support. The
default location is in the Programs group, which can be accessed from the
Windows Desktop. Refer to the PDF documentation for details regarding both
hardware and software.
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.
