Frequently Asked Questions
Have a Question?
-
Is the 3312 adapter suitable for automated test environments?
Yes, the 3312 is ideal for automated testing applications. It provides reliable communication for instrument control via programming interfaces including ActiveX and DLL tools compatible with Visual Basic, C++, Delphi, and LabVIEW development environments.
-
What operating systems are supported by the 3312 adapter?
The Array 3312 supports Windows operating systems including Windows 7, 8,, 10 and 11. The provided software includes drivers and control applications optimised for these platforms.
-
Can multiple instruments be controlled through one 3312 adapter?
The 3312 provides point-to-point communication with a single instrument. For multi-instrument control, each instrument requires its own adapter, or use RS-485 networking with appropriate converters for daisy-chain configurations.
-
What is the maximum communication distance with the 3312 adapter?
The adapter supports direct connection to instruments. For extended distances, consider using the Array 3313 RS-232 to RS-485 converter in conjunction with appropriate cabling for multi-drop or long-distance installations.
-
How do I connect the 3312 adapter to my Array instrument?
Connect the adapter's instrument-side connector to the communication port on your Array power supply or electronic load rear panel. Connect the USB end to your computer, install the drivers, and use the provided software to establish communication.
-
What communication protocols does the 3312 adapter support?
The 3312 supports Array's proprietary communication protocol over serial TTL interface. It handles standard UART communication with configurable baud rates from 4800 to 38400 bps, matching the instrument's communication settings.
-
Can I use generic USB to TTL converters instead of the Array 3312?
Whilst generic adapters may provide basic connectivity, the Array 3312 is specifically designed for Array instruments with optimised signal levels, timing, and protocol compatibility. Using the dedicated adapter ensures reliable operation and full feature access.
-
Does the 3312 adapter require special drivers or software?
Yes, the Array 3312 comes with dedicated drivers and control software on CD. The software provides comprehensive instrument control capabilities and programming interfaces for automation applications.
-
What is the difference between USB to TTL and USB to RS-232 adapters?
USB to TTL adapters like the 3312 convert USB signals to TTL voltage levels (typically 0-5V), whilst RS-232 uses higher voltage swings (±12V). TTL interfaces are common in modern instruments and microcontrollers, offering better noise immunity and power efficiency than RS-232.
-
Which Array Electronic instruments are compatible with the 3312 adapter?
The 3312 USB to TTL adapter is compatible with Array 3644A, 3645A, and 3646A programmable power supplies, as well as Array 3710A and 3711A DC electronic loads. It provides the essential interface for PC communication with these instruments.
