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.Ĭompact in size (3.6×2.5×1.3 in – L x W x H incl. The ADQ-USB 3.0-ISO can protect computers and USB devices effectively against interference voltages, while also eliminating ground loops. 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 +70☌, the Alldaq USB 3.0-ISO isolators are suitable even for applications in harsh environments.

USB GROUND LOOP ISOLATOR MAC OS

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. For USB devices requiring more current, the external power supply version ADQ-USB 3.0-ISO-W can provide 900 mA according to the USB 3.0 specification. Without an external power supply the USB isolator can source up to 200 mA at the device port. The ESD protection of the data lines is ensured by transient-voltage-suppression diodes up to ☑2 kV (contact discharge) and ☑5 kV (air-gap discharge) according to IEC 6.

USB GROUND LOOP ISOLATOR PC

The isolation voltage between PC and USB device is 1 kV (continuous) for the model ADQ-USB 3.0-ISO-PS and 1.0 kV (< 60 sec) for the model ADQ-USB 3.0-ISO-W. Optical isolators or optocouplers are frequently used to provide ground loop isolation. can remove many ground loop problems, and sometimes safety problems too. In digital systems, which commonly transmit data serially (RS-232, RS-485, USB, FireWire. The external power input is protected against reverse polarity and short-circuits. Ground loop currents can be induced by stray AC magnetic fields (B, green). For industrial and automotive applications, the ADQ-USB 3.0-ISO-W version can accept 10 to 36 Vdc from an external power source via a two-pin lockable Phoenix-type connector to power devices with up to 900 mA.

The model ADQ-USB 3.0-ISO-PS includes a +5-V power adapter with a lockable 5.5-mm barrel connector (bayonet lock) for a safety. The ADQ-USB 3.0-ISO isolators automatically detect SuperSpeed (5 Gbit/sec), High-Speed (480 Mbit/sec), Full-Speed (12 Mbit/sec) or Low-Speed (1.5 Mbit/sec) 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. What do you think would be the best approach to get rid of the ground loop? It seems I need a USB hub that would isolate the ground of each device plugged in, but I'm not sure where to find such a hub.The Alldaq ADQ-USB 3.0-ISO series of USB 3.0 isolators support the full USB 3.0 SuperSpeed data rate of 5 Gbit/sec. Here's a video with a minimal reproduction of the issue with the Bluebox, Pi and NTS-1: I thought that powering everything from the same power source would avoid these kind of issues, but I was completely wrong If I connect the Digi's to Pi for USB midi, the hum is also there.īasically, as soon as I connect anything to the Raspberry Pi the ground loop comes in. Every time I connect a device to the Pi for midi, the hum appears for that device. If I run the OPZ or NTS-1 from battery, there's no hum (but no midi).

Then, the OP-Z, NTS-1 and Nanokey are connected to the Pi for both power and midi (no other possible choice here). The Digi's, Typhon, Bluebox and Raspberry Pi are directly connected to the power supply. Raspberry Pi (acting as Midi Host/through)Īs soon as I plug anything into the Raspberry Pi for midi, the ground loop hum comes (heavily!). Digitone & Digitakt (with ripcord USB adapters)

USB GROUND LOOP ISOLATOR PORTABLE

I'm trying to assemble a full portable setup composed exclusively of USB-powered gear, but I'm having a hell of a ground loop issue (not interferences).Īll my gear is powered from a single USB power supply:
