Network Settings

LYNX Network Settings section deals with connection of LYNX with the network. It is typically internet or local LAN in some cases. Depending on model, LYNX supports the following options to connect to network:

  1. Wi-Fi: LYNX connects to a Wi-Fi network (router) to access the internet/local LAN. All models of LYNX support connection to internet through Wi-Fi.

  2. Ethernet: LYNX connects to internet through Ethernet (RJ45 jack).

    • By default, it assumes DHCP connection (in which IP address is assigned by router). In this case, no further change in setting is needed.

    • LYNX also supports static IP address configuration under advanced Ethernet settings.

  3. 4G/LTE (Sim card): LYNX connects to internet through 4G/LTE SIM card.

    • Support of all 4G networks, independent of carriers. LYNX has been tested with all carriers in India.

    • Option to provide carrier APN. Though, this is not critical.

    • Support of external antenna for in-panel applications.

  4. None (Offline): LYNX is not being connected to any network and is being used as display unit. This mode is also used for debugging purpose.

Read and Write Network Settings

  1. Click on "Read Network Settings" button. The network settings will be populated in configuration page from LYNX. It may take 1-2 seconds for this process.

  1. Various network Settings are populated in the configuration page from LYNX. Apply required changes in given section.

3. After all the changes are completed, click on Write Network Settings button. This will update the network settings in the LYNX. A popup is displayed. After clicking on Write Network Settings, wait for 2-3 seconds for update.

4. Click on Reboot LYNX button to reboot the LYNX. Alternately, LYNX can be power cycled. LYNX will use updated Network Settings after reboot. During initial runs, it is better to cross check whether settings have been updated in LYNX after the reboot.

Selection of Network Settings in LYNX

Network Selection radio button is used to select a given type of network. Details of each network type is covered in following sections.

Complete steps of Network Selection are covered in the video below:

Updating Wi-Fi Settings in YuDash LYNX

  1. In the above settings, the SSID#1 has been changed from yudashdemo to my_test_1 and password has been updated. Similarly, WIFI SSID#2 has been changed to mytest2.

LYNX WiFi Features and Specifications

  1. LYNX supports DHCP Wi-fi connection only.

  2. LYNX supports 2.4GHz Wi-Fi only. 5GHz Wi-Fi networks are not supported.

  3. LYNX supports DHCP Wi-fi connection only (IP address issued by Wi-Fi router).

  4. For on-premise solutions, Wi-Fi with local LAN access can be used (without any need for internet connection).

  5. LYNX has in-built Wi-Fi antenna. There is no provision of external Wi-Fi antenna.

  6. There is provision to provide two Wi-Fi networks. By default, LYNX attempts connection to first Wi-Fi (Wi-Fi SSID#1 and Wi-Fi Password). In case it is not connected, it will attempt to connect to (Wi-Fi SSID#2). It is not mandatory to fill both Wi-Fi settings.

Please consider the following in case you are facing Wi-Fi connection issues:

  1. Check special characters and space in Wi-Fi SSID and password entry boxes.

  2. Create a simple SSID name and password using mobile phone and first connect to that Wi-Fi.

Updating 4G/SIM LTE Settings in LYNX

When 4G/LTE sim card is selected, LYNX uses 4G connection for connecting to internet. In general, there are no settings required.

  • There is option to provide APN (Access Point Name) which can be selected based on carrier. In our observation, it is not mandatory to update this.

  • The option 4G TimeOut (sec) is the time LYNX will attempt to connect to the SIM network. Depending on network strength, it takes up to ~20 seconds for LYNX modem to connect to network. This setting can be tweaked in case of connectivity issues.

Updating Ethernet Settings in LYNX

Ethernet port can be used to connect to cloud (or on-premise server). This is enabled by selecting Ethernet in Network Settings as below.

Ethernet supports dynamic IP (DHCP) and static IP option. By default, dynamic IP is assumed in which IP address is assigned by local LAN router. In this case, there is no further configuration in this section. This is most common use-case for most of the applications.

For assigning static IP to LYNX for network connection, please refer to Ethernet Settings section.

For using ethernet port for network connectivity, there is no need to enable Ethernet within LYNX settings. Just selection of Ethernet in Network Selection is sufficient.

Following is sample connection of Ethernet RJ45 jack connected to LYNX:
