Chapter Two Quick Start
The following materials are required for this test:
E78-DTU, antenna, power adapter , 485 communication cable
1
、
First install the antenna for E78-DTU, then install the power supply, and ensure that the status of the DIP switch is correct. The
user can choose the crimping method or the power adapter for power supply according to the needs, and choose one of the two;
2
、
Use USB to RS485 to connect the computer to E78-DTU;
3
、
Start a serial port debugging assistant, select the serial port baud rate as 9600bps, and check the mode as 8N1. After configuring
the network access parameters through the AT command or the configuration tool ( note: different types of devices have different
region files, the default factory region file of the device is EU868 , if customers need to use other region files, they can switch
region files by configuring AT commands through the serial port. For AT commands, see AT command configuration
instructions ), the device will automatically send a network access request, and the device can be connected to the network after
the nearby gateway accepts the request.
Access demo:
This demonstration kit uses E78-DTU (900LN22) as the node, and E890-868LG12 as the gateway to connect
to the free ChirpStack Application Server test server for communication testing; the corresponding settings of the
node-side OTAA access method are as follows:
