By utilizing I-button, the procedure on how to register Driver ID is taken by step-by-step instruction as follows:
Step 1. Please insert and remove the Master I-button (by adding the master / by removing the master).
Step 2. Please insert a new I-button within 10 seconds after removing it.
Step 3. Upon completing the procedure for the Step 1 and Step 2, the ID of I-button is registered or
deregistered automatically.
When a device with registered I-button is set to control immobilizer of a vehicle, only the drivers whose IDs have
been registered are allowed to drive the vehicle. If other drivers drive the vehicle, the device will activate the
immobilizer and the vehicle cannot be driven by those people. .
9-12. Fuel Sensor
The ST300F supports reading fuel sensor data via RS232.
After the power of fuel sensor has been turned on, the sensor outputs the first RS232 data elapsed after 50
seconds. After the first data is output, the sensor outputs RS232 data every 10 seconds. (The sensor sample is
fixed to this condition by sensor firmware. It is a special feature of ESMUS01.)
Active time from wakeup to timing of RS232 data output:
60 seconds
Time length of Power down:
120 seconds
[RS232 Cable Connection]
