### &#x20;**Setting DHCP (letting the router assign an IP address) on your PAX S300**&#x20;

2. Enter your password
3. Scroll down 1 page and press "2. Communication"
4. Enter your password again
5. Scroll down 1 page and press "3. LAN Parameters"

### &#x20;**Using a static IP address on your PAX S300**

If the IP address assigned to your PAX device changes, you will need to update the IP address before the point of sale will be able to communicate with the device again. To prevent this from happening, you can setup the device to use a static IP. Here is how:

1. Press and hold the F Key and 1 Key together to access the main menu.
2. Enter your password (default password is the current date in MMDDYYYY format)
3. Scroll down 1 page and press "2. Communication"
4. Enter your password again
5. Scroll down 1 page and press "3. LAN Parameters"
6. Press "1. Lan Type"
7. Press "2. Static"
8. Go back to the home screen by using the back button on the screen several times.
