Chapter 3 Module Introduction
3.1.2 ADAM-2520Z
Wireless Sensor Network Modbus RTU Gateway
The ADAM-2520Z is designed as a gateway to translate the IEEE 802.15.4 WPAN to
Modbus Network. In a WPAN, the ADAM-2520Z works as a coordinator to collect and
translate data from end devices to host PC.

Note! ADAM-2510Z router and ADAM-2520Z gateway are always in normal
transmission mode during operation, and which power consumption will
be higher than other end devices to shorten battery life, therefore, sug-
gest ADAM-2510Z and ADAM-2520Z adopt external power input for
main power source and battery power for backup power source.
