Description
Connect to multiturn data input (MDI) pin of singleturn sensor and
pull-up resistor to VDD.
Connect to multiturn clock (MCL) pin of singleturn sensor and pull-up
resistor to VDD.
5V power input.
Connect to multiturn data ready (MRDY) pin of singleturn sensor and
pull-down resistor to GND.
Presets internal multiturn position to zero. Can be connected to a
push-button switch and pull-up resistor for easy calibration. Must be
pulled up to VDD if not used.
Connect to iC-PMX NCS (pin 26) and pull-up resistor to VDD.
Connect to iC-PMX MISO (pin 29) and pull-down resistor to GND.
Connect to iC-PMX SH (pin 25) and pull-down resistor to GND.
Connect to iC-PMX VWC via a resistive voltage divider to allow mea-
suring Wiegand pulse voltage without overloading the iC-TW14 ADC.
Connect to GND if Wiegand pulse voltage measurement diagnostic is
not required.
Connect to iC-PMX HOP (pin 23). Connect to GND if iC-PMX single-
turn sensors are not used.
Connect to iC-PMX HON (pin 24). Connect to GND if iC-PMX single-
turn sensors are not used.
Connect to iC-PMX MOSI (pin 28).
Connect to iC-PMX SCK (pin 27).
Serial output for communication with PC for setup and diagnostics.
Serial input for communication with PC for setup and diagnostics.
