Link2-LAN | Serial to Ethernet | Instrument Networking
The Link2-LAN smart instrument trans-receiver device that connects directly to your compatible devices and gives wired and optional wireless connectivity to upload data to the RemoteDNA network. Link2-LAN can control up to 4 devices and provides relay outputs to connect to audible alarms, visual alarms or other relay controlled devices.
The Link2-LAN has two primary modes of operation:
Data Uplink
Typically the Link2-LAN is used to relay data from up to 4 serial (RS-232 or RS-485) devices to the RemoreDNA web portal. Connectivity is achieved through the built in 10/100 Ethernet (RJ-45 jack) or optional wireless radio add-on.
Device Server
Additionally, a Link2-LAN captures data being received from a directly connected serial device. Devices either send their own unsolicited data, or the Link2-LAN is used to poll data out of the device. This data is encrypted and transmitted in a low bandwidth format to compatible remote monitoring systems such as the RemoteDNA Web Portal.
The Link2-LAN has the following external ports:
Power
The power port enables the Link2-LAN to be powered from an external DC 9-36V power source.
Ethernet / RJ45
The Ethernet port connects the Link2-LAN to the local area network or Internet to be configured using its web based configuration pages. A configuration tool enables all local LAN based DR-1500 units to be easily identified.
RS-232 Serial Ports (x2)
For connection to RS-232 serial port wired as a DTE.
1x3 IDC Header (RS-485)
Connects to RS-485 half duplex serial port.
2x5 IDC header
For connection to configurable serial port.
1x9 IDC header
Digital I/O, GND, and the SPDT relay come out on this header.
