BiSS to PC-LPT Adapter
MB3A
Protocol converter for connecting BiSS/SSI sensors to the LPT port on a PC
Scope of delivery: ready-to-use adapter;
LPT device driver (Win 98/ME, 2000/XP) and BiSS
master PC software for downloading
DESCRIPTION
The BiSS to PC-LPT Adapter enables BiSS or SSI
sensors to be connected to a PC easily and at low
cost.
The parallel printer port is used as hardware link,
whereas by software an SPI compatible data communication is emulated, granting a speedy measurement
data transmission and the configuration of the adapter.
Regarding the sensor side BiSS/SSI communication is
carried out via differential RS422 lines, optionally via
single ended signals when removing a jumper.
Technical Data
Ë Synchronously triggered measurement data collection from up to 3 BiSS sensors or one SSI encoder
Ë BiSS data rates up to 10 Mbit/sec.,
SSI up to 4 Mbit/sec.
Ë Protocol compatible with BiSS Master iC-MB3
Ë Connection to the PC parallel printer port
Ë Operates from a single 5 V voltage supplied via the
sensor connection or solder terminals
Size approx. 50 mm x 70 mm
