Wireless 8 Channel Analog Input Sensor Node

The V- Link - 200 wireless sensor node features eight analog input channels

designed to accommodate a wide range of Wheatstone bridge and analog

sensors, including strain, load cell, torque, pressure, acceleration, vibration,

magnetic field, displacement, and geophones. There are four channels for single-

ended sensor measurement, four channels for differential sensor measurement,

and an on-board internal temperature sensor.

To acquire sensor data, the V-Link - 200 is used with a LORD Sensing data

gateway such as the WSDA-101 or WSDA-1500 Base. V-Link-200 sensor nodes

come with the following components.

The LED indicators on the V-Link-200 include operational modes showing when

the node is booting up, idle and waiting for a command, sampling,

resynchronizing, or if there is an error. see Table 2 - below describing basic

indicator behavior.

V-Link-200 Wireless Sensor Node Quick Start Guide SYSTEM OPERATION 1. Install Software Sensor nodes have three operational modes: active , sleep , and idle . When the node is sampling, it is in active mode. When sampling stops, the node is switched into idle mode, which is used for configuring node settings, and allows toggling between sampling and sleeping modes. The node will automatically go into the ultra low- power sleep mode after a user- determined period of inactivity.

V-Link-200 Wireless Sensor Node Quick Start Guide 3. Establish Gateway Communication 4. Connect to Nodes The WSDA-101-Base USB gateway is used in this example. For information on how to use other gateways, refer to the gateway or SensorConnect user manual. The node can be connected with the automatic node discovery feature and by manually entering the node address and then searching for it on the current gateway communication frequency.

V-Link-200 Wireless Sensor Node Quick Start Guide 10. Power Supply The V-Link-200 Wireless Sensor Node can be powered by an external source. Apply only the input voltage range specified for the VLink-200. Connect to a power source that is near the device, is accessible, and adheres to all national wiring standards. Compliance with wiring standards is assumed in the installation of the power source and includes protection against excessive currents, short circuits, and ground faults.
