High Performance isolated BiSS to PC Adapter (USB)
GALVANIC ISOLATION OF POWER SUPPLY, GND, BiSS SIGNALS AND SHIELD
Rev A2, Page 5/7
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.
