BiSS to PC-LPT Adapter

MB3A

Protocol converter for connecting BiSS/SSI sen-

sors 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 commu-

nication 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.
