Operation Guide 3.1 USB Configuration CT10x can be powered and configured via a Type-C port for configuration and debug. 1. Download ToolBox software from Milesight website. 2. Connect the device to a computer via the Type-C port. 3. Open the ToolBox and select type as General, then click password to log into the ToolBox. (Default password: 123456) 4. After logging into the ToolBox, you can check device status and change device settings. 7 3.2 LoRaWAN Settings LoRaWAN settings are used to configure the data transmission parameters in the LoRaWAN® network. Basic LoRaWAN Settings: CT10x supports basic configurations like join type, App EUI, App Key, and other information. You can also keep all settings by default. 8 Parameters Description Device EUI Unique ID of the device which can also be found on the label. App EUI Default App EUI is 24E124C0002A0001. Application Port The port used for sending and receiving data, default port is 85. Join Type OTAA and ABP modes are available. Application Key Appkey for OTAA mode, default is 5572404C696E6B4C6F52613230313823. Device Address DevAddr for ABP mode, default is the 5th to 12th digits of SN.
