
configuration;
Large single package, single package is up to 240 bytes;

Simple and efficient power supply design, support power adapter or crimping mode, support 8~28V power supply.

Transmit power is up to 22dBm, multi-level adjustable, with all technical indicators meeting European industrial

standards.
Support LBT function, the transceiver automatically waits to send data according to the current ambient noise

intensity. The communication success rate of the module in harsh environments is greatly improved.
Remotely configure or read wireless module parameters by sending command packets wirelessly.

Support communication key function to effectively prevent data from being intercepted;

Multi-level relay networking can be realized ， which effectively extends communication distance for

ultra-long-distance communication.


Operating temperature range: -40 ° C ~ +85 ° C, to adapt to a variety of harsh working environment.

All-aluminum alloy casing, compact size, easy installation and good heat dissipation; perfect shielding design, with

good electromagnetic compatibility and strong anti-interference ability.
Multiple protection functions such as power reverse connection protection, over-current protection, and antenna

surge protection greatly increase the reliability of the device.
Powerful software functions, all parameters can be programmed: such as power, frequency, air data rate, address ID,

etc.
Ultra-low power consumption, standby current is only 12V / 39mA (lower power consumption in power saving

mode and sleep mode);
with built-in hardware watchdog and precise time layout, once an exception occurs, the transceiver will

automatically restart, and continue to work according to the previous parameters.
