Horizon DG10 Quick Start Guide Device Architecture 2 3 1 1 LTE antenna USB interface 23 LED Working Environment Power Consumption Operating System 2.5W Windows (Win7/Win8/Win10) Mac (Mac OS 10.10 or above) Linux Chrome OS Operating Temperature Storage Temperature Humidity -10°C ~ 45°C -40°C ~ 70°C 5% ~ 95% (Non-condensing) Hardware Configuration Remove the cover of the dongle. Insert the SIM card into the SIM slot on the side and put it in the right position. Re-attach the cover. Step1 Step2 Step3 Install SIM Card Connect and Turn on the USB Dongle 1. Make sure the dongle is connected to a USB port. 2. Unfold the antenna Connect to the Network It takes several seconds to connect to the LTE network. The sequence of different LED status is as follows. 1. LED indicator starts with a red light. 2. Then LED indicator becomes blinking green. 3. When connected successfully, LED shows static green. Login to the Web Management Page Launch the web browser, enter http://192.168.0.1 in the address bar, and press Enter. Software Configuration Step1 Enter the username and password, and click Login. Step2 Step3 After the password is verified, you can login to the web management page. The default username and password are both admin. If you want to view or configure the dongle, you should use the super account to log in to the web management page. The default super username is superadmin, and the password is admin. LTE Settings Choose Network > LTE Settings. On LTE Settings page, you can set the configuration of the LTE network. In the Status list, you can view the LTE status, such as Frequency, RSSI, RSRP, RSRQ, CINR, SINR, Cell ID and etc. Step1 Step2 Step3 The POWER indicator does not turn on. Make sure the dongle is connected properly to a USB port. Make sure the output power of the USB port is compatible with the dongle. Try to unplug, then plug the dongle into the USB port again or into a different USB port. If the problem persists, please contact the authorized local service suppliers. Fails to Login the web management page. Make sure that the dongle is powered on. If the problem persists, please contact the authorized local service suppliers. The dongle fails to search for the wireless network. FAQs Check if the antenna is open and not folded. Check if the indicator light is static green. Check if the dongle is placed in an open area If the problem persists, please contact the authorized local service suppliers. The parameters are restored to default values. If the dongle is powered off unexpectedly while being configured, the parameters may be restored to the default settings. After configuring the parameters, down- load the configuration file and restore the desi- red settings quickly. The dongle does not support SIM card hot-plug, please confirm that the device is powered off when the SIM card is inserted or removed.
