USB Gateway

M=BUS to USB interface contained in a ruggedized aluminium housing.

USB Gateway
  • Support of one M=BUS line
  • Ruggedized aluminum housing
  • Very low power consumption
  • USB2.0 standard
  • Integrated memory to store user-defined data (e.g. documentation, sensor information)
  • Extended bus test features
  • Slide-in rack mounting

The M=BUS USB Gateway is the interface between M=BUS and USB 2.0 and connects the bus directly to a host PC. The M=BUS links the bus participants in a daisy chain manner by a single Æ2.5 mm coax cable to communicate with the M=BUS Loggers and provide power and trigger. Depending on the connected sensors up to two data loggers can be powered via USB. An external power input allows the support of a fully equipped M=BUS with 32 participants. So this small gateway device is ideal to test M=BUS Sensors or M=BUS lines. The external power could also be supplied by an accumulator which allows a stand-alone function without connection to an USB port.

Sensor calibration or firmware updates can be done directly from host PC. The M=BUS USB Gateway uses the same software interface as the Ethernet or NA33 Gateway. So a complete test can be performed in CrashSoft 3.

For advanced bus test functions a passive terminator is installed. This device for a simple bus termination offers the possibility to perform bus and electronic tests under load.

A local non-volatile data memory of 2 MByte can be used as storage for data sheets or documentation and can be configured as log-device for the communication.
