Lots of information such as potential divider, application, and sensor are described in this application note. This application note contains info about interfacing, and error.
In the application note you can get description such as digimatic sensors, and source code. Below are grabbed from the application note:
Mitutoyo sensor interface Application Note: Interfacing ToothPIC DARC-I to Mitutoyo Digimatic sensors FlexiPanel The Mitutoyo data was clocked in from two opencollector outputs from each sensor to the ToothPIC, via pull-up resistors and filter circuits as recommended by Mitutoyo. It includes the following commands: 038400 038401 0385xx 0209 Read sensors Check for sensor presence and read Buzz buzzer for xx units of 10ms Enter sleep state (cycle power to wake) In response to a button press or a 0384yy command, DARC-I reads the sensors and the battery power and reports with the following Page 2 11-Jun-05 AN-080605 © FlexiPanel Ltd Patents apply and/or pending www.FlexiPanel.com
Additionally, the application note gives you information such as sensors, and firmware.
