# LYNX Configuration

LYNX is configured through Wi-Fi using a laptop, tablet or mobile phone. There is no need to install any software or LAN wiring.

{% hint style="info" %}
LYNX now also supports configuration through LAN cable. Please refer to [Device Configuration](https://docs.yudash.com/dc/dc1) section.
{% endhint %}

Following are 3 simple steps to initiate LYNX configuration.

**Step 1**: On LYNX bootup, the device waits for 5 seconds for user to start configuration server. The LYNX screen shows the following message (with countdown from 5 to 0):

During the countdown, short press the Config button (connected with SW GND top right terminal) to start the configuration server.

{% hint style="info" %}
Do not long press the Config Button. Just push and release!
{% endhint %}

**Step 2:** Once the button is pressed, the device will enter in AP (Access Point) mode, meaning a Wi-Fi network will be broadcasted. The Wi-Fi SSID name and password are displayed on the LYNX screen. Connect the laptop to the given Wi-Fi.

Details of Wi-Fi created by LYNX are displayed on the LYNX screen and are as follows:

1. Wi-Fi SSID: ***yu10000492***
2. Wi-Fi password: **12345678**
3. LYNX IP address: ***192.168.4.1***

{% hint style="info" %}
**Troubleshooting Guide to connect to LYNX Wi-Fi**

1\) In some cases, Wi-Fi may be shown as "Open network". In this case, no need to enter Wi-Fi password.

2\) At times, the Wi-Fi setting on laptop may be showing "Connecting.." instead of "Connected to Wi-Fi" after LYNX Wi-Fi is selected. No need worry. Please open the Configuration URL (192.168.4.1) on laptop. It should simply open.

3\) In case of further trouble, please "Forget" any previously stored Wi-Fi names linked to LYNX.
{% endhint %}

**Step 3:** This is how LYNX configuration page looks like on laptop.

{% hint style="info" %}
While laptop is connected to local Wi-Fi of LYNX, internet will not be accessible on the laptop.
{% endhint %}

LYNX will keep the configuration server running for up to 5 minutes on inactivity. All LYNX configuration will be done through this page as covered in subsequent sections.

### LYNX Configuration Sections

Following are the main sections in YuDash LYNX Configuration page:

1. **LYNX Device Information**: This is read-only section with LYNX model, hardware and firmware information.
2. **Network Setting**: This section is used to configure network connectivity of LYNX. Depending on model, LYNX can connect to internet through (a) 4G/LTE (SIM card) (b) Wi-Fi or (c) Ethernet LAN. It can also work in offline mode (when it is used for local storage or display only).
3. **LYNX Settings**: This is main section in which all features of LYNX are configured. It includes (a) Data send frequency, (b) Feature enable/disable (given industrial protocol) and (c) Custom cloud selection. Detailed configuration of a given feature is done in subsequent sections.

1. **Part No**: The device part number.
2. **Serial No**: Unique serial number of the device.
3. **Hardware Ver**: Hardware PCB version.
4. **Firmware Ver**: LYNX firmware version.
5. **Default Device Settings**: By default, each YuDash LYNX gateway is pre-configured with "YuDash Cloud". Effectively, given LYNX IoT gateway is mapped to a unique "device" on YuDash IoT platform.
6. **Get Mac Address** **Button**: This button fetches the MAC address of the LYNX IoT gateway. This MAC address is used for both Wi-Fi and Ethernet.&#x20;

{% hint style="info" %}
MAC address of LYNX is required for use of IoT gateway in enterprise networks for security purpose. The MAC address is required for "White Listing" of the gateway.&#x20;

In some cases, MAC address and static IP of device is tightly coupled to gain access to the network.&#x20;
