1.Introduction

E64-DTU (433NW20) is suitable for lo w-power, main-mu ltiple slave star networks. Its biggest feature is that it

supports up to 31 slave data to be sent to the host at the same time, and supports WOR working mode of slave, with a

minimu m receiv ing power consumption of about 3mA. Data reliab ility and correctness are guaranteed by strict data

checking and automatic retransmission mechanism between master and slave.

The E64-DTU ((433NW20) module supports both host and slave modes. In the host mode, the module listens and

receives data from mult iple slave machines. In slave mode, the user can set the module to work in WOR mode or send

mode. WOR mode allows the host to init iate data wake -up to the slave, wh ile sending mode only allows the slave to

initiate data to the host.

The ma ximu m transmission power of E64- (433NW20) module is 100mW, using command transmission mode,

operating at 425~ 451.3mh z. The module USES UA RT serial port to co mmunicate with user MCU, and its working

voltage range is 8V~28V .

★ 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 shielding, prime electro magn etic 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 dat a rate, address and so on.

★ Ultra-low power consumption, standby current is only 14mA (even lo wer under power-saving and sleep modes), TX

current ≤0.13A.

★ Embedded watch-dog and precise time layout, modem will restart automat ically upon abnormal situat ion and work

with previous parameters.

★ The transceivers adopt original SEMTECH SX1278 chip, customers highly co mment the products because of the

super reliability.
