Add an RS232 serial port with circuit isolation to your laptop or desktop computer. Let me try, I'll let you know if I happen to crack it. 1 Port FTDI USB to Serial RS232 Adapter Cable with Optical Isolation. However, tt seems to be a difficult circuit and I don't think I would be able to design this one. Yes it's definitely an interesting concept to investigate. Thank you, John Waterman Analyzing the Circuit Idea Might this be a useful DIY project for the pages of Homemade Circuit Projects? An example of such an isolator is shown here:Ī less costly alternative to many of the other the eye-wateringly expensive isolators also shown on EBay might be really useful. The incoming light beam will be linearly polarized by the Beamsplitter before converting to a circular polarization due to the quarter waveplate. One answer to this problem would be to place a USB Isolator between the usb input of the test circuit and the PC. Optical Isolator is made from a combination of Polarizing Beamsplitter Cube and Quarter Waveplate. I had heard that one must use extreme caution when placing the oscilloscope probe earth of this (and any) oscilloscope on the test circuit if that test circuit is also brought to mains earth potential by plugging it in to a USB port to power it.Ī wrong move could zap the test circuit and possibly the oscilloscope 🙁 A video by Dave of EEV Blog explains the dangers more clearly than I can.

Can also be used as “power injector“ for USB devices normally powered by the USB port but which can´t provide enough current for a reliable operation of the USB device.Some time ago I purchased a Digitech 40MHz Dual Channel USB Oscilloscope that i would now like to learn to use with a PC via USB.

Decoupling of different ground levels in industrial control technology.

Spike protection in the automotive area, e.

Efficient suppression of ground loops – Ideal for music studios and event technology The HDFX-350-TR can be operated either with 5V power from the HDMI source (Tx only) or via USB power.

Electrical isolation between measurement instruments and PC.

The Alldaq ADQ-USB 3.0-ISO-W USB 3.0 Isolator is compact in size (3.6” x 2.5” x 1.3” - L x W x H incl. Typical applications include: electrical isolation between measurement instruments and PCs, rejection of ripple pickup in studio equipment, removing differing ground potentials in industrial control equipment, and protection against voltage peaks in automotive set-ups. The ADQ-USB 3.0-ISO can protect computers and USB devices effectively against interference voltages, while also eliminating ground loops. The USB to serial adapter features integrated optical isolation circuits and surge protection to protect your critical, sensitive control equipment against. An optional DIN rail mounting kit is also available for permanent installations.

Housed in a robust aluminum housing with rubber bumpers and designed for an operating temperature from -20 to +70degC, the Alldaq USB 3.0-ISO isolators are suitable even for applications in harsh environments.

The Alldaq USB 3.0 isolators are compatible with Windows, MAC OS and Linux systems, and downward-compatible with USB 2.0/1.1/1.0 equipment. The ESD protection of the data lines is ensured by transient-voltage-suppression diodes up to ☑2kV (contact discharge) and ☑5kV (air-gap discharge) according to IEC 6. The isolation voltage between PC and USB device is 1kV (<60s). The ADQ-USB 3.0-ISO isolators automatically detect SuperSpeed (5Gbit/s), High-Speed (480Mbit/s), Full-Speed (12Mbit/s) or Low-Speed (1.5 Mbit/s) connections The ADQ-USB isolators can be used for the electrical isolation of USB measurement instruments to avoid ground loops to solve problems in industrial and automotive applications as well as in professional sound studios and event and show equipment. The re-clocking design guarantees a stable USB connection at all speeds.

This allows USB 3.0 SuperSpeed devices to be electrically isolated from a host PC or other peripherals at full performance. The external power input is protected against reverse polarity and short-circuits. The Alldaq ADQ-USB 3.0-ISO-W USB 3.0 Isolator supports the full USB 3.0 SuperSpeed data rate of 5Gbit/s and can accept 10 to 36 VDC from an external power source via a 2-pin lockable Phoenix-type connector to power devices with up to 900 mA.
