Before you believe a bad review about us

We would like to respond openly to every negative review about us. Many are posted anonymously, so we cannot reach those customers directly. This open letter is our reply, and we would be grateful if you took a moment to read it.

But here is what a one-star review will never tell you:

  • We import from 70+ official distributors. That is why you pay far less than local retail — and why delivery takes longer. We publish the date before you pay, never after.
  • You can pay only when your goods land in Johannesburg. Pay on Arrival, no full payment up front. Ask yourself what scammer offers that.
  • Nobody has ever lost money with us. You get the product, or you get a refund. There is no third option, and there never has been.
  • We are part of the ITwork group — ten years trading in Europe, nine stores, thousands of positive reviews.
  • Johannesburg and Cape Town stores open this year — real shelves, real stock, walk in and buy the same day.

We are not satisfied with our review scores, and we are not going to fix them by hiding anything. We are fixing them by being faster, clearer and easier to reach than any reason to complain.

Read the full letter — photos and video of real shipments, and a straight answer to every accusation.

For KNX integrators and building automation engineers, the Busch-Jaeger USB-M-1.11 is a compact DIN rail interface that connects a PC to a KNX TP1 bus. It enables programming, diagnostics, and bus monitoring directly from ETS software.

Key specifications

  • KNX medium: TP1 (twisted pair)
  • PC interface: USB 2.0, type B port
  • Power supply: via KNX bus, 21-30 V DC
  • Current consumption: max. 12 mA
  • Module width: 2 TE (36 mm)
  • Electrical isolation between USB and KNX
  • Status LEDs for KNX and USB
  • Protection degree: IP20
  • Operating temperature: 0 °C to +45 °C
  • Storage temperature: -20 °C to +70 °C
  • Compatible with ETS3.0d and higher (ETS4, ETS5, ETS6)
  • Housing material: thermoplastic

Why choose it

This interface provides reliable galvanic isolation between the PC and the KNX bus, preventing ground loops and protecting both sides. Its compact 2 TE width saves space in distribution boards, and the LED indicators give immediate status feedback.

Ideal use cases

  • Commissioning KNX installations with ETS
  • Bus diagnostics and troubleshooting
  • Long-term monitoring in control cabinets
  • Integrating KNX with PC-based visualization or logic

Good to know

The device is powered entirely from the KNX bus, so no external power supply is needed. It mounts on a standard DIN rail and connects to the bus via the red/black KNX terminal.
