MB3A BiSS to PC-LPT ADAPTER Release A1, Page 1/2 ORDERING INFORMATION Type BiSS to PC-LPT Adapter Order Designation MB3A Description / Options 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 BiSS Plug Pin Configuration J2 (9-pole SUB-D) Pin 1 2 3 4 5 6 7 8 9 Name VB MA % MA !
