Restoring a Sensor Connection
If you cannot connect to a sensor because the sensor is not detected in the [Sensor List] and the IP address
set in the sensor is unknown, you can execute [Re-assign IP forcibly] to forcibly change the IP address of the
sensor and connect.
The sensor’ IP address will be re-assigned as shown below based on the IP address settings of the Touch
Finder (PC Tool) that is connected to the sensor.
• Execute this function with the Touch Finder (PC Tool) in a one-to-one connection with the sensor. If connected to
multiple sensors, IP address assignment will be performed for all sensors and reconnection will not take place nor-
mally.
• The reassign IP address function is valid for Version 1.84 and later sensors.
1 Configure the network settings (IP address, subnet mask, and Default gateway) of the Touch
Finder (PC Tool).
2 Connect the sensor and the Touch Finder (PC Tool) in a one-to-one connection.
(If the sensor is connected via a network, disconnect the sensor from the network.)
3 Press (Run Mode) - [TF settings] - [Re-as-
sign IP forcibly].
4 Make sure that the sensor and Touch Finder are
connected in a one-to-one connection, and
press [Yes].
