FCC ID: XJQMSLINK0011 Wireless Analog Input Node

LORD QUICKSTARTGUIDE SG-Link-200-OEM Wireless Analog Input Node The SG-Link-200-OEM is a small, wireless, low-cost, two-channel analog input sensor node ready for OEM integration. Featuring one differential and one single-

ended analog input channel and an internal temperature sensor. The SG-Link-

200-OEM supports high resolution, low noise data collection at sample rates up to 1 kHz. Users can easily program nodes for continuous, periodic burst and event-triggered sampling with SensorConnect. To acquire sensor data, the SG-Link-200-OEM is used with a LORD Sensing WSDA gateway, and comes with the following configuration options.

Node Operational Modes 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. The node will not go into sleep mode while sampling. 3. Install Software Install the SensorConnect software on the host computer before connecting any hardware. Access the free software download on the LORD Sensing website at:

http://www.microstrain.com/software 4. Establish Gateway Communication Drivers for installation. With the software installed, automatically whenever the gateway is plugged in. the USB gateways are included the SensorConnect software the USB gateway will be detected 1. Power is applied to the gateway through the USB connection. Verify the gateway status indicator is illuminated, showing the gateway is connected and powered on. 2. Open the SensorConnect software. 3. The gateway should appear in the Controller window automatically If the gateway is not is active on the host with a communication port assignment. automatically discovered, verify the port computer, and then remove and re-insert the USB connector. Figure 6 - Node Operational Modes 3 Figure 7 - USB Gateway Communication SG-Link-200-OEM Wireless Analog Input Node Quick Start Guide 5. Connect to Nodes Several methods can be used in SensorConnect to establish communication with the nodes: the automatic node discovery on the same frequency, automatic node discovery on a different frequency, and add node manually. A. Automatic Node Discovery on Same Frequency If the base and node are on the same operating frequency, the node will populate below the Base Station listing when powering on the SG-Link-200-

OEM. B. Automatic Node Discovery on Different Frequency If a red circle with a number appears next to the Base Station, the node is operating on a separate radio channel. Select the Base Station and then select the Nodes on Other Frequencies tile. Figure 8 - Node Discovered On Same Frequency Figure 9 - Node On Other Frequency Highlight the new node being added and select Move Node to Frequency

(#). Figure 10 - Move Node 4 SG-Link-200-OEM Wireless Analog Input Node Quick Start Guide C. Manually Add Node Adding a node manually requires entering the node address and its current frequency setting. If the node failed to be added, a failure message will appear. This means the node did not respond to the base station which could indicate the node is not in idle mode or it may be on another frequency. If "Add Node Anyway" is selected, it will associate that node with the channel entered but it is likely there will be a communication error. If the node was not in idle, move the base station to the frequency of the node and issue a "Set to Idle" command. Figure 11 - Add Node By Address Figure 13 - Failure to Add Node the node was successfully added, If appear and it will be listed under the Base Station. two confirmation messages will Figure 12 - Add Node Confirmation 5 2. Under Low Pass Filter, select 552 Hz from the Filter Cutoff drop down menu. Figure 15 - Low Pass Filter 3. From the Wireless Node Configuration menu, select Calibration >

Cal Tools > Shunt Cal to calibrate Microstrain. Figure 16 - Node Calibration Menu SG-Link-200-OEM Wireless Analog Input Node Quick Start Guide 6. Configure Node Node settings are stored to non-volatile memory and may be configured using SensorConnect. To access the node configuration menu,under Devices select the node and then the Configure tile. The configuration menus show the channels and configuration options available for the type of node being used. For this example the SG-Link-200-OEM tester board is on Differential channel 1. 1. From the Wireless Node Configuration menu, select Hardware >

Input Range for Differential channel 1, select +/- 2.5 V from the drop down menu. Figure 14 - Hardware Configuration Menu 6 SG-Link-200-OEM Wireless Analog Input Node Quick Start Guide 7. Configure Sampling Setting and Start Data Acquisition 1. Left click on the Base Station > Sampling, and indicate the nodes to be sampled by checking the box to the left of each node. 2. Under Sampling, select Sample Rate from the drop down menu, select Continuously to sample indefinitely. 3. Select Apply and Start Network. Figure 17 - Sampling Setting 4.

The SG-Link-200-OEM is susceptible to damage and/or disruption of normal operation from Electrostatic Discharge (ESD). ESD may cause the device to reset, which may require user intervention to continue data acquisition. The SG- Link- 200- OEM employs a 2.4GHz IEEE 802.15.4- compliant radio transceiver for wireless communication. The radio is a direct-sequence spread spectrum radio and can be configured to operate on 16 separate frequencies ranging from 2.405 GHz to 2.480 GHz. Following the 802.15.4 standard, these frequencies are aliased as channels 11 through 26. For all newly manufactured nodes, the default setting is 2.425 GHz (channel 15).
