2. Quick Start

2.1. Hardware preparation before use

Take the transparent transmission between E90-DTU(433L30E)-V8 and E90-DTU(433L30)-V8 as an example.

In order to test E90-DTU(433L30E)-V8, the following hardware is required:

One PC with network port;

One E90-DTU(433L30E)-V8, hereinafter referred to as "gateway radio";

One E90-DTU (433L30)-V8 digital radio, hereinafter referred to as "serial radio" (for example, if necessary,

buy it separately);

TX433-JKD-20P 2 antennas (inner thread, inner needle);

Two DC12V-1A power adapters;

One network cable;

One USB to RS-485 serial cable;

2.2. Software Preparation

The product details on the Ebyte official website provide the download of the network debugging assistant

"NetAssist" and the serial port assistant "XCOM", as shown in the following figure. Official website address:

https://www.ebyte.com.

Chengdu Ebyte Electronic Technology Co.,Ltd.

E90-DTU(433L30E)-V8 User Manual

Download the configuration tool corresponding to the product details, use the "Ebyte Network Configuration Tool"

for "Gateway Radio", and use the "RF_Setting_E90.exe" configuration tool for "Serial Radio".

2.3. Hardware connection

Connect the antenna to the E90 radio and connect to the power supply (DC: 8~28V), RS485 connection, network

cable connection:

Connect the antenna

Above: "Gateway

Radio" on

Next: "Serial Radio" is

connected

Connect RS-485 for "Serial

Radio"

Connect the network

cable for the "Gateway

Radio"

2.4. Wireless parameter configuration

2.4.1. Configure "Serial Modem"

Step 1: Turn on the power and connect the USB to RS-485 serial cable (serial cable A is connected to the radio

485_A, serial cable B is connected to the radio 485_B);

Step 2: Check whether the radio is working in configuration mode, if not in configuration mode, configure the DIP

switch to enter configuration mode according to the figure below;

Step 3: Open the configuration host computer "RF_Setting_E90.exe" and select the corresponding serial port;

Step 4: "Open Serial Port" and click "Read Parameters", then click "Restore Factory Settings";

Step 5: Set baud rate to 9600, check to 8N1, "continuous transmission" mode, as shown in the picture below, click

"Write Parameter";

2.4.2. Configuring "Gateway Modem"

Step 1: Turn on the power and connect the PC and the "Gateway Radio" with a network cable;

Step 1: Perform factory configuration on the "Gateway Radio", press and hold the Reload button until the indicator

lights are all on;

Step 2: Modify the IPv4 configuration of the PC, use a static IP, and ensure that the "gateway radio" and the PC are

in the same network segment. The factory default IP is 192.168.4.101, so configure the static IP of the PC as

192.168.4.100 as shown in the following figure:
