MB5U

High Performance isolated BiSS to PC Adapter (USB)

Rev A2, Page 5/7

GALVANIC ISOLATION OF POWER SUPPLY, GND, BiSS SIGNALS AND SHIELD

The MB5U provides VDD, GND, Shield and the BiSS

signals MA+, MA-, MO+, MO-, SL+ and SL- with gal-

vanic isolated. The MB5U field GND and shielding

potential does not need to be identical with the adapter

GND and adapter shield to prevent ground loops and

potential differences.

N.B.:

MB5U is galvanically isolated. A common GND poten-

tial (field and host) and shield potential is not required.

BiSS POWER SUPPLY CONTROL

The MB5U supplies the VDD voltage only with allocat-

ing and initializing the adapter. With closing the adapter

resource or the software the voltage is turned off to

permit a safe unplugging of connected devices. Non

volatile content needs to be saved e.g. in an EEPROM

before closing the interface adapter in any software

environment.

N.B.:

MB5U may not be supplied into VDD. If the sensor

needs to be supplied by 3rd power supply, the GND

needs to be identical and any backwards supply into

VDD of the adapter MB5U is not permitted.

BiSS MASTER IP MB100

The MB5U is based on the MB100 BiSS master IP.

With this implementation it is possible to connect one

or more BiSS C devices or a single SSI device to the

adapter. BiSS C protocol is fully supported. The adapter

supports up to 8 BiSS C slave devices.

With BiSS there is 10 MBit/s RS422 maximum clocking

available. The SSI protocol operation is also config-

urable.

With high speed buffered transfer the real-time mea-

sured data can be block-wise transferred to a Windows

PC application for analysis, documentation, data pro-

cessing, etc..

MU1C ADAPTER AND CABLE SET

The iC-MB5 iCSY MB5U-CABLE1 contains addition-

ally an extension cable to MU1C. This cable connects

MU1C with the BiSS interface and does supply the

MU1C board with VDD and GND.
