Wireless Network Module

An accurate and reliable solution for sending process signals between remote field sites, the WNM wireless network module from Moore Industries provides a low cost wireless communications link in rugged or impassable terrain. A single unit can transmit for up to 48.3 km, with the ability to act as a repeater for a virtually unlimited transmission range and networking when a direct line of sight cannot be established. Bi-directional, it employs spread spectrum frequency hopping technology to avoid interference problems caused by crowded radio spectrums. This technology allows multiple radio networks to use the same band while in close proximity. Operating at standard frequencies of 902-928MHz or 2.4-2.4835GHz (up to 24.1km range), the module does not require a regulatory license and can typically be installed without performing costly RF surveys. When set in the smart switch Ethernet (SSE) mode, it enhances the speed and reliability of data packet transmission by determining the most efficient path to broadcast (including direct to a single radio or to some or all radios in a network) on a packet-by-packet basis. Ideal for use with the company’s NCS NET concentrator system, the module can also be used with other SCADA and distributed I/O systems. Models are available for data communications networks that use Ethernet and serial RS-485 communications. In each network one module is set as a master, which can be set to communicate with a single remote unit in a point-to-point architecture or with multiple remote units in a point-to-multipoint architecture. The wireless network module is easy to use and installed, as it can be factory-configured to fit user specifications. In addition, a free PC configuration software allows end users to perform on site configuration, parameter changes and add new modules to a network. The module utilizes 128-bit ES encryption, 32-bit CRC error detection and ARQ (automatic resend query) for robust and secure communications. The industrial DIN-rail mount metal enclosure allows use in rugged environments, including ambient temperatures from -40 to 75°C and relative humidity of 5 to 95%.
