Updating MD30 software over cable connection

During the software update, MD30 must be connected to a power supply.

Download and extract the ZIP package on your laptop.
Remove the 8-m (26-ft) extension cable from your data collection system.
Connect the extension cable wires to the screw terminal of the serial-to-USB cable as follows (pins 1, 2, and 4).
Connect the USB cable to your laptop.
When prompted, define the port to which MD30 is connected.

To check the port, select Start > Device Manager > Ports (COM & LPT)
On your laptop, select Start > Command Prompt.
Go to the folder where you extracted the ZIP package and double-click UpdateClient.exe.
When prompted for the port, type the port to which the sensor is connected. For example:
```
Serial port name [COM0]: COM3
```
Command Prompt lists the files that are in the directory.
Select the firmware file using the number indicated in the beginning of the row. For example:
```

Disconnect the wires from the screw terminal, and connect the 8-m (26-ft) extension cable back to your data collection system.
