In order to calibrate and configure a PONSEL sensor, CALSENS Software and an RS-485 adapter are required. If the cable has been connectorized for use with an SDL500 data logger, a NexSens UW-USB-485R cable is required. If the sensor cable is terminated in flying leads, the In-Situ Modbus Sensor Communication Device Kit can be used.

1. Install Calsens software on the computer.
2. Connect the USB end of the RS-485 Adapter cable to the computer and allow the drivers to install.
3. Connect the sensor to the RS-485 adapter.
- If connectorized, connect the PONSEL sensor’s UW plug to the RS-458 Adapter’s UW receptacle.
- If flying lead, connect the wires to the In-Situ box following the below list.
- PONSEL Blue: Not connected
- PONSEL Red: In-Situ Red (Bottom Left)
- PONSEL Black: In-Situ Black (Bottom Right)
- PONSEL Green: In-Situ Green (Top Left)
- PONSEL White: In-Situ Blue (Top Right)
4. Open CALSENS software on the PC.
5. Select USB from the Select a port dropdown.
6. Select the USB adapter from the Port number dropdown.
- If using the NexSens UW-USB-485R select USB-RS485 Cable.
- If using the In-Situ Communication Device select USB TROLL Com.
7. Uncheck the Remove echo box.
