1.Introduction
1.1. Brief Introduction
E62-DTU (433D30) 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 433MHz band.
Module has the function of frequency hopping spread spectrum (FHSS), in the process of digital transceiver module
both sides according to the frequency hopping algorithm automatically synchronous jump in as many as 50 frequency
points (user customizable FM and sequence number), and greatly improve the anti-interference of the module, the 433 m
frequency hopping technology in a leading position in the industry module with time full duplex (TDD) features, at the
same time of receiving data, can send data, without waiting for receiving complete in some air rate and serial port baud
rate can be realized under the combination of full duplex serial transmission。For example: under the air rate of 64 k, the
serial port baud rate can be realized under 9600 BSP and full-duplex data transmission in a row, in this case, there is no
limit to send and receive the packet size, module can keep low latency/high response at the same time, to ensure that the
data is transmitted to the other party as soon as possible.

Parameter
Description
Baud rate
The serial port baud rate of a wireless data station at work，1200bps～115200bps。
Odd-even
check
Support 8N1:no check ；8E1:even-check；8O1:odd-check；Both are 8-bit data bits and 1-bit stop
bits.
Air data rate
（bps）
Wireless communication rate, also known as air baud rate air rate high, data transmission speed,
transmission of the same data time delay is small, but the transmission distance will become
shorter. 64kbps is the most recommended value
Transmitting
power
In order to ensure the working efficiency, it is recommended to use the maximum power. If the
transmitted power is reduced, the communication distance will become shorter and the required
current will be reduced
FEC
The lost or interfered data can be partially corrected by complex encoding, which can improve
the equivalent receiving sensitivity by about 3dBm. Turning off this function can reduce the
communication delay.
Transmission
mode
Transparent transmission, and send-as-received fixed points, broadcasting is not supported
Wake Up
Time
There is no direct relationship with the communication delay. If the customer needs low-power
applications, this option shall be adjusted as required to ensure the communication stability.
This parameter is self-adaptive and needs no attention from the user.
IO driven
By default, select the internal TTL signal drive mode。

Frequency
hopping ID
The internal serial ID of the wireless data transmission modem, regardless of the Modbust
address. Modem with the same station serial ID can communicate with each other, and this
feature can be used to implement software grouping.
Channel
It is equivalent to the frequency at which the wireless data transmission station works. Each
channel corresponds to its different working frequency. In theory, different frequency channels
cannot communicate with each other.
Frequency
hopping
channel
number
The more channels are hopped between when the radio is working, and the more the number of
hopping channels, the better the anti-interference performance.

11.Note
1. Please keep the warranty card of the equipment which includes the factory number (and important technical
parameters) and is important for user's future maintenance and new equipment.
2. Transceiver during the warranty period, if the quality of the product itself rather than man-made damage or
lightning and other natural disasters caused by damage, enjoys free warranty; please do not repair by yourself, the
problem and please contact with our company when problem occurring, we offer the first-class after-sales service.
3. Please do not operate the transceiver in some flammable places such as coal mines or near explosive atmospheres
(such as detonators).
4. Please use the appropriate DC power supply, high frequency interference ability, small ripple, and enough load
capacity are required; it’s better to have over current, over voltage protection and lightning protection and other functions

to ensure that transceiver working properly.
5. Please do not use it in the working environment beyond the transceiver environmental characteristics , such as
high temperature, humidity, low temperature, strong electromagnetic fields or dust larger environment.
6. Please do not continuously keep transceiver to transmit in full capacity, or the transmitter might be damaged.
7. Please connect the ground with the external ground of the power supply (such as PC, PLC, etc.) , otherwise it is
easy to burn out the communication interface; do not plug the interface with power supplying.
8. When testing, please connect the antenna or 50 Ω load, otherwise transceiver will be damaged easily ;the
distance from the antenna is better than 2 meters, so as to avoid harm, please do not touch the antenna when transmitting.
9. Wireless data transceiver has different communication distance in different environments, communication
distance is influenced by temperature, humidity, obstacle density, obstacle volume and electromagnetic environment; in
order to ensure stable communication, it is recommended to reserve at least 50 % of the communication distance.
10. When communication distance is not perfect, it is recommended to improve the antenna quality and the
installation mode of the antenna. You can send mail to sup[email protected]om for support.
11. When choosing power supply, it is recommended to keep at least 50% current left and the ripple must not
exceed 100mV.
