1.Introduction
Brief Introduction
1.1.
E34-DTU (2G4H20) is a fu ll duplex wireless data transmission module for point-to-point transmission( Has both
RS232 and RS485), transmission power is 100mW, transparent transmission mode, wo rking in 2400MHz band
high-performance 2.4g wireless module, UA RT serial port interface, transparent transmission, at the same time support
3.3v or 5.0v system, packet loss automatic retrans mission, support automatic frequency hopping, anti-interference ability
is very strong.
E34-DTU (2G4H20) in order to ensure the secrecy and anti-interference of co mmun ication, co mpared with
fixed-frequency communication, frequency-hopping communicat ion 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 co mmunicat ion
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 ab ided by do mestic and fo reign design specifications such as FCC CE and CCC,
meet various rf related certification, and meet export requirements
Features
1.2.
★ All core co mponents 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 g rade
products.
★ Alu minu m alloy case, co mpact size, great heat dispersion; good shield ing, prime electro magnetic co mpatibility 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-lo w 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 automat ically upon abnormal situation and work
with previous parameters.
★ The transceivers adopt original n RF24L01P+ chip, customers highly co mment the products because of the super
reliability.
