The BiSS to PC-USB Adapter enables BiSS or SSI sensors to be connected to a PC easily and at low cost. The USB port supplies the adapter as well as the connected sensor, for which the 5V(up to 50mA, through Pin 4)*and 12V(up to 90mA,through Pin 1) as galvanically isolated voltages are available. An external wall power supply can also be connected to deliver other voltagesor higher currents. TheBiSS/SSI communication is accomplished by differential RS422 wires with separate potentials and cycle rates of up to 10 Mbit/sec.
The BiSS and I2C to PC-USB Adapter has an additional plug for I2 Cor SPI communication. The USB port supplies the sensors via the I2C plug with 5V(up to 250 mA, through Pin 4 - no galvanic isolation). If there is load applied to the BiSS connector, the maximum current supplied via the I2C plug is decreased. For more power, an additional external power supply is recommended (the wall power supply does not supply the I2C plug). I2C multi-master capability is not provided.
