BiSS TO PC-USB ADAPTER

Rev B2, Page 5/7

Instructions

Before connecting the BiSS adapter to the PC please make sure you have installed the latest USB driver!

Connect the adapter via the USB AB cable and start the "BiSS_xx.exe". Select the USB operating mode. The

display in the "Mode" description field should show "MB3U (MB3Z)" - the adapter is now ready to operate.

Sensor-specific settings

To set the BiSS Master for the sensor(s) connected to it, select Config Slaves and manually configure the BiSS

parameters (data lengths, CRC polynomials, etc.) according to the sensor’s data sheet. If there is a BiSS device

description file from the sensor manufacturer in the working directory (iC-Haus example: "idbiss6943.xml"), you

can use Auto Config. You will receive a message such as BiSS-Identifier "Slave 1: Manufacturer iC-Haus

GmbH, Device iC-NQX2; Resolution=1024, 0 Bits period counter as sensor data!".

Configuration files

Transmission parameter settings can be stored to a *.cfg file for later use with the "BiSS_xx" software.

"Save BiSS-Master-Config" writes an BiSS Master Chip configuration description into a *.txt file (e. g. setup of

iC-MB3).

Main causes for errors:

• Using more than one software.

→ Please make sure that only one software is accessing the BiSS MB3U adapter at the same time.

• Insufficient power supply for all sensors attached.

→ The adapter will not respond if there is an overload due to the sensor(s) connected. Please use the wall

power supply.

• Invalid transmission parameter settings.

→ Please check the sensor specific BiSS slave parameters, such as CRC polynomial etc.
