1. Product Overview

The RF Neulink NL6000 is an integrated radio modem that provides reliable bi- directional RS-232 data transmissions on a land mobile radio channel. Configurable RS-232, radio, and packet data parameters provide the NL6000 with the flexibility necessary for use in both simple and complex networks.

In its simplest configuration, the NL6000 transmits wireless data from one modem to another to send instructions and receive a response. In many cases, the factory- configured default parameters make the unit ready to use after just setting two address IDs. Figure 1 shows a simple system to transmit data between two terminals.

In a more sophisticated configuration, the NL6000 provides wireless communication between multiple units in a network. A unit configured as a base station can transmit instructions to multiple remote units and collect responses from those remotes for analysis and management reporting. Configuration of multiple units is a simple task using the menu-driven user interface. Figure 2 shows a system for maintaining the water level for a number of water tanks.
