NEL-MESH Wireless RS485
NEL-MESH Wireless MODBUS / RS485 to RF converter for ISM band applications operating in the 860 – 930 MHz frequency band. Which allows the application to reach 15db / 28dBm output power creating a mesh next work > 1000 meter. The converter collects the data from MODBUS (RTU) slave device and converts it to desired data format.
Any gateway (DCU) collects the data and sends to the cloud using GPRS. 4 LEDs inform about the substantial operating and error conditions. RF status is indicated by the Green LED. Sending or receiving data is indicated by a two-color LED yellow/orange. Orange color LED indicates the Configuration status.

Traditional RS-485 network
In a traditional RS485 network, each device requires wires, +, - (shield). All devices in same network need to be daisy-chained together from the first device to last to form a complete connection. The wiring process is labour-intensive and tends to be a challenge in most retrofit projects.
With NEL-MESH
The NEL-MESH wireless RS485 network solution completely eliminates the need for RS485 communication wiring. Each device, or group of devices can directly connect to NEL-MESH transceiver, and the job is done. The NEL-MESH transceiver transparently runs with any protocol and transmits data and commands wirelessly within a network. The NEL-MESH communicates from salve to master, from sensors and meters to data acquisition servers and gateways cost effectively and with minimal challenge.
