USB-inSync is a control platform that enables the construction of PC-based fibre-optic test equipment.
Four-channel module builds on synchronised DAQ
Adelaide-based Fiberbyte has released its first product - the USB-inSync DAQ-2500X data acquisition module.
Generation-II technology takes this to another level by providing distributed synchronisation and control to subnanosecond accuracy - a world first.
Maestro hubs offer six USB2.0 High Speed downstream ports, each with their own transaction translator for optimum mixed speed USB operation.
The Maestro-iS22 and -GS22 both offer USB-inSync clock phase compensation.

Current transducers maintain accuracy
A new series of DC current transducers provides tighter accuracy to 1.0% full-scale for more stable operation over a wide temperature range from -40 to +85C.
This system compensates for arbitrary USB hub and cable lengths between all attached USB-inSync devices ensuring the clocks of each attached USB-inSync device maintain subnanosecond phase accuracy.
The flagship of the Maestro range, the USB-inSync Maestro-GS22 provides the ultimate in precision distributed timing.
The GS22 distributes either its precision onboard clock or an external reference clock to the attached USB-inSync devices.
The GS22 can synchronise to and read the absolute time signals from a GPS time server.
This enables the device to provide the absolute time-stamp accuracy of GPS to a distributed USB-inSync system.
Fiberbyte calls this "USB-RealTime".
USB-RealTime has other far reaching implications for USB-based test systems.
Multiple independent/remote PCs can now operate synchronous USB-inSync environments - sharing a common clock.
The Maestro-GS22 is able to use a GPS time server's absolute timestamp - anywhere on the planet.
So any two USB-inSync systems can be synchronised to absolute time, anywhere.
Fiberbyte has combined USB-inSync with its USB-RealTime technology enabling unprecedented accuracy, flexibility and expansion in demanding distributed test environments.
Upcoming offerings in this area include the Legato series of distributed digital timing and control devices for laboratory automation and control.
For the first time ever, adding additional synchronised control and data acquisition channels is as simple as plugging another USB-inSync device into the hub.
Engineers can build the expandable synchronous system they want, and their managers can control costs.
The flexibility and power of USB-inSync is being readily accepted as the future of USB-based test equipment.
It is the obvious choice for PC I/O applications where performance, portability, cost, or most significantly, scalability are significant considerations.
No other interface can provide a distributed, subnanosecond accurate, real-time PC-based environment - all this without the overhead of a real-time operating system and operating side-by-side with conventional USB devices.
Using USB-inSync products has been made simple with Fiberbyte's extensive software suite.
The Control Center application provides complete PC control and data logging with multiple devices for users with no programming experience.
Experienced users can access the full functionality of the devices through Fiberbyte's COM server interface which provides support for most modern programming languages and applications.
LabView drivers are provided for interfacing into existing test applications.
Fiberbyte's initial range of products is finding applications in laboratory automation and data acquisition markets.
Field applications in geophysical exploration are also benefiting from the flexibility and ruggedness of the DAQ-2500X data acquisition modules.
Fiberbyte is able to integrate USB-inSync technology with third party I/O devices, creating innumerable application possibilities for OEMs.
