Q: What is the maximum range of the E290-400R30D?
A: Under ideal open field conditions with a 5dBi antenna and 2.4kbps air rate, the module can achieve a stable communication distance of 10km due to its 1W transmit power and high sensitivity.
Q: Does this module support transparent transmission?
A: Yes. It supports half-duplex transparent transmission and is fully compatible with MODBUS RTU protocols over RS485, making it an ideal wireless replacement for wired cables.
Q: How do I configure the module settings?
A: Configuration is handled through standard AT commands. You can connect the RS485 port to a PC via a converter and use serial debugging software to set frequency, power, and air data rates.
Q: What is the benefit of ChirpIoT™ technology?
A: ChirpIoT™ is an advanced spread spectrum modulation that offers significantly better anti-interference and range than traditional FSK/GFSK, allowing for reliable data links even in noisy industrial RF environments.
Q: What power supply is required for 1W output?
A: The module accepts 4.5V to 5.5V DC. However, to ensure the full 30dBm (1W) output power, a stable 5V DC supply capable of providing at least 650mA peak current is required.
