1.Introduction

1.1. Brief Introduction

E34-DTU (2G4H20) is a full duplex wireless data transmission module for point-to-point transmission( Has both RS232 and RS485), transmission power is 100mW, transparent transmission mode, working in 2400MHz band high-performance 2.4g wireless module, UART serial port interface, transparent transmission, at the same time support

3.3v or 5.0v system, packet loss automatic retransmission, support automatic frequency hopping, anti-interference ability is very strong.

E34-DTU (2G4H20) in order to ensure the secrecy and anti-interference of communication, compared with fixed-frequency communication, frequency-hopping communication is more covert and difficult to be intercepted. Support address function, host can transmit data to any address of any channel module, network relay and ot her applications; The air speed is high, so the transmission speed is fast, the delay is small and the data throughput is large. It is especially suitable for applications requiring small delay and large data volume, such as real-time remote control with good anti-interference ability. Even if some frequency points are interfered, it can still carry out normal communication on other frequency points that are not interfered, and it has been mass produced and widely used in related industries

E34-DTU (2G4H20) is Strictly abided by domestic and foreign design specifications such as FCC CE and CCC, meet various rf related certification, and meet export requirements

1.2. Features

★ All core components are originally imported; our transceiver modems have much advanced functions with smaller size and lower cost.

★ The top TX power is 100mW, all technical parameters meet European industrial standards. ★ Temperature compensators are adopted to make the frequency stability better than ±1.5PPM.

★ Operation temperature range: -40℃～+85℃, applicab le for various harsh environment, it is real industrial grade

products. ★ Aluminum alloy case, compact size, great heat dispersion; good shielding, prime electromagnetic compatibility and

strong anti-interference.

★ Power reverse & overload protection and antenna surge protection functions significantly improve the reliability. ★ Parameters can be configured by programming, such as TX power, frequency point, air data rate, address and so on. ★ Ultra-low power consumption, standby current is only 25.5mA (even lower under power -saving and sleep modes), TX

current ≤0.14A .

★ Embedded watch-dog and precise time layout, modem will restart automatically upon abnormal situation and work with previous parameters. ★ The transceivers adopt original nRF24L01P+ chip, customers highly comment the products because of the super reliability.

2. Operation

Main parts

1、 First step is to mount antenna, then battery, making sure the dial switch is on its right status. User gets on the power

by choosing either VCC/GND or power adapter.

2、 Using USB-(RS232) converter or USB-RS(485) converter or other way to link computer and DTU.

3、 Firing up two XCOMs, choosing Baud rate 9600bps, 8N1, the setting which serial port transmission can be

achieved.

4、 User needs to open the mode switch first before link DTU with computer if the user want to modify parameters.

Firing up E34-DTU 数传电台配置软件 (E34-DTU parameter configuration application) to modify related parameters. The mode switch must be reopened to achieve transmission after the configuration.
