The ZN-241G is a low-cost, 802.15.4 wireless data modem that can provide an auto-configured, wireless replacement for RS-232 cable in office environments, and can also serve as a platform for multi-drop RS-485 networks in industrial settings. Housed in a ruggedized metal enclosure, the ZN-241G replaces hard wiring in commercial environments that make wired connections challenging or impractical or that require frequent reconfiguration.
For point-to-point communications, ZN-241Gs configure the link automatically; all that’s required is plugging the devices into two serial interfaces and turning on power. Point-to-multipoint links are set up by via an included utility that simplifies the configuration of network IDs and channels, and a repeater function allows a remote node to relay data through another remote node when the direct path is blocked. The ZN-241G offers RS-232, USB, and RS-485 interface options, and operates license-free worldwide at 2.4 GHz with over-the-air data rates of up to 250 Kbps.
