Built on 802.15.4 technology, the ZN-241G is ideal for a range of applications from simple RS-232 cable

replacement to sophisticated multi-drop RS-485 networks and everything in between. Available in RS-232,

USB and industrial RS-485 models, the ZN-241G has an Auto-Configure feature that removes the need for

ANY modem configuration. For demanding applications, the ZN-241G is completely configurable to support

a variety of different needs. With -a full 100mW of transmitted power, the ZN-241G can cover an entire

factory floor or bridge distances of a mile or more outdoors.

Value

Even with the high transmit power, the Murata ZN-241G is priced to fit any budget, making the choice to replace wires even more compelling. With the

multiple interfaces and multiple operating modes, the ZN-241G delivers unsurpassed value for any application. The ZN-241G is built on standard

802.15.4 radio technology and provides a crisp 250Kbps over-the-air data rate using Direct Sequence Spread Spectrum methods. The result is a

wireless network with plenty of data throughput for most applications and the robustness to provide reliable, worry-free data transmission.

Versatility

Operating in the international license-free 2.4GHz frequency the ZN-241G can be deployed around the world. With the choice of an RS-232, a USB or an

RS-485 interface, the ZN-241G has a model to fit almost any application. The Auto-Configure feature makes setting up point-to-point links a snap. The

broadcast mode coupled with the RS-485 interface, provides a simple replacement for half-duplex, multi-drop RS-485 wiring. The ZN-241G also has a fully-

addressable multi-point mode to support more demanding applications. Whatever your need, the ZN-241G can handle it.

Even though the ZN-241G is a low cost wireless modem, it includes a repeater function to help overcome signal blockages. This function allows a remote

node to relay data through another remote node when the direct path is blocked. Similarly, a remote node can receive data through another remote node

when the direct path from the base is blocked.
