Welcome to www.nodehelp.com
www.nodehelp.com is a website which contains the help pages associated with each data entry field of our Node-resident firmware. A Node (with a capital “N”) refers to our Ethernet Nodes. These run special firmware, which allows them to be discovered and configured using our PC-resident Node Manager Software, or online using our Node-resident firmware, which has its own IP address. Three types of Nodes are available, as described below.

The Nodes with attached devices can be accessed over a LAN or a WAN once they have been configured via our software or firmware. Supporting application software can be provided by our actory, such as Instrument Setup, Data

Data Display, and Data Logging software -- or it can be customer written.

Instruments from other manufacturers can be operated on an RS485 bus supported by our Ethernet-to-serial device server Nodes if the host computer uses the Modbus TCP protocol and commands suitable for these instruments. Our Nodes can also be set up in a tunneling mode without a protocol and simply pass through data packets without processing.

Our help pages are listed below. For additional technical support, please call us at 714-434-6131 and ask for Ethernet Tech Support.

Understanding Nodes and Devices

Our basic LNET Ethernet option board plugs into a host 1/8 DIN digital panel meter, counter or timerand provides to provide a 10/100BaseT Ethernet interface. This Node supports only one device, namely the host meter, which can be ordered with a choice of displays, signal conditioner boards, relay output boards, and analog output boards.

Our LNET485 Ethernet-to-serial device server option board also plugs into a host meter. This Node provides an RJ45 connector for a 10/100BaseT Ethernet interface, plus an RJ11 connector to serve as a device server for up to 31 meters on an RS485 bus. RS485 wiring is via commercial straight-through 6-wire data cables. The host meter can be ordered with a choice of displays, signal conditioner boards, relay output boards, and analog output boards.

Our LTNET485 DIN-rail Ethernet-to-serial device server provides an electrically isolated 10/100BaseT Ethernet interface via an RJ45 Ethernet connector, plus an RJ11 connector and screw terminals to serve as a device server for up to 31 meters and transmitters on an RS485 bus. The RJ11 connector and screw terminal are wired in parallel. This DIN-rail mounted Node is the preferred Ethernet gateway for a bank of transmitters with screw terminal connectors.
