The USB port supplies the adapter as well as the connected sensor, for which the 5V (up to 50 mA, through Pin 4)* and 12 V (up to 90 mA, through Pin 1)* as galvanically isolated voltages are available. An external wall power supply can also be connected to deliver other voltages or higher currents. The BiSS/SSI communication is accomplished by differential RS422 wires with separate potentials and cycle rates of up to 10 Mbit/sec. USB-B Plug 4-pole size approx. 42 x 95 x 24 mm Power Supply Socket 2-pole, 6.6/1.9 mm DIN 45323 Technical Data BiSS Interface • Synchronously triggered measurement data collection from up to 3 BiSS sensors or one SSI encoder • BiSS data rates up to 10 Mbit/sec., SSI up to 4 Mbit/sec. • Protocol compatible with BiSS Master iC-MB3z • USB 2.0 compatible • Galvanic encoder signal isolation • Galvanically isolated sensor supply sourced from the USB port (+12 V / 90 mA, +5 V / 50 mA)* • Plug-in power supply can be connected for sensors with higher power needs BiSS Plug 9-pole SUB-D 1 6 5 9 BiSS Plug 9-pole SUB-D Figure 1: iC-MB3 iCSY MB3U * 100 mA for +5 V and +12 V available starting from 2008 Copyright © 2010 iC-Haus http://www.ichaus.com MB3U, MB3U-I2C BiSS TO PC-USB ADAPTER Rev B2, Page 2/7 BiSS Plug Pin Configuration Pin 1 2 3 4 5 6 7 8 9 Name VB MA + MA VDD MO GND SL + SL MO + Function +12 V Sensor supply (90 mAmax )* Optional: powered by ext. supply Clock output P Clock output N +5 V Sensor supply (50 mAmax )* +5 V High-level signal Optional: master data output N Ground (0 V) Data input P Data input N 0 V Low-level signal Optional: master data output P USB-B Plug 4-pole I2C Plug 10-pole 2 1 Power Supply Socket 2-pole, 6.6/1.9 mm DIN 45323 size approx. 42 x 95 x 24 mm Power Supply Socket Inner contact Negative pole Outer contact Pos. pole (9 to 15 V DC, 1 Amax ) BiSS Plug 9-pole SUB-D Figure 2: iC-MB3 iCSY MB3U-I2C PC-USB Adapter With I2C Extension I2C Plug Pin Configuration For I2C-Link PIN 1 2 3 4 5 6 7 8 9 10 Name SCL GND +5 V SDA SDA GND Function Serial Clock Line Ground Reserved Supply Voltage Reserved Reserved Serial Data Line Reserved Serial Data Line Ground The BiSS and I2C to PC-USB Adapter has an additional plug for I2C or SPI communication. The USB port supplies the sensors via the I2C plug with 5 V (up to 250 mA, through Pin 4 - no galvanic isolation). If there is load applied to the BiSS connector, the maximum current supplied via the I2C plug is decreased. For more power, an additional external power supply is recommended (the wall power supply does not supply the I2C plug, see Figure 3). I2C multi-master capability is not provided. Note: To use I2C, pin 7 and pin 9 must be short.

Download from http://www.ichaus.de/product.php?prod=MB3A/MB3U Installation After unzipping the "BiSS_xx.zip", the following files are located in the selected directory. (xx is a placeholder for revisions) → BiSS_xx.msi → mb3u_usb_driver.exe → mb3_lpt_driver.exe → readme.txt Note: Administrator rights are required to run installation. 1. The installation of the software starts by executing the "BiSS_xx.msi" installation package. Follow the onscreen instructions to finish the installation procedure. 2. USB driver need to be installed to access the BiSS PC Adapter. Execute the mb3u_usb_driver.exe installation package and follow the on-screen instructions. This process can take a few minutes. 3. Installation will make the software "BiSS_xx.exe" available in the selected working directory. The execution of this file will start the software. Figure 4 shows a screenshot of the start up window. File "idbiss6943.xml" is a BiSS device description file for BiSS slave ICs of iC-Haus. Please contact the manufacturer of your sensor for an appropriate device description file or set the transmission parameters yourself later. Figure 4: Screenshot MB3U, MB3U-I2C 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. Description of Menu Section Button Load Config-File Save Config-File Save BiSS-Master-Config Exit Description Loads BiSS transmission parameter settings from file Writes BiSS transmission parameter settings to file Writes an interface configuration description to file Quit software No Hardware Switch to no hardware to terminate PC to adapter communication Intel-Mode (MB3D-P) For use with BiSS PC-LPT evaluation board (MB3D) Motorola-Mode (MB3D-P) For use with BiSS PC-LPT evaluation board (MB3D) SPI-Mode (MB3D-S / MB3A) For use with BiSS PC-LPT adapter MB3A, eval board MB3D-S USB-SPI-Mode (MB3U) For use with BiSS PC-USB adapter MB3U Config BiSS BiSS bus communication settings Config Slaves BiSS transmission parameter settings Show Sensor Data Window Enables separate window to display sensor data Figure 5: Upper section MB3U, MB3U-I2C BiSS TO PC-USB ADAPTER Rev B2, Page 6/7 Button Initialize Read Output Write File Description Initializes BiSS bus after configurations are made Reads in sensor data Saves sensor data to file Figure 6: Middle section (one tab each per slave) Button Read Reg Write Reg Load File Save File Description Loads register configuration from sensors to software GUI (hex) Transfers the displayed register configuration to sensors (hex) Loads register configuration from a file (hex) Saves register configuration to a file (hex) Figure 7: Lower section (valid for all slaves) Button Read Reg Write Reg Load File Save File SENSSEL Reset SENSSEL Code Send BiSS Command Description see Middle Section see Middle Section see Middle Section see Middle Section Mask for slave selection.
