SG-Link®-200
Wireless Analog Input Node
Wireless Simplicity, Hardwired Reliability™
The SG-Link®-200 is a 3-channel wireless sensor with a rugged, weatherproof
enclosure. It includes onboard PGA, filtering, and a high-resolution ADC for
precise measurement of a large range of sensor types including strain gauges,
load cells, pressure transducers, and accelerometers. The SG-Link-200
is ideal for both test and measurement and long term condition monitoring
applications.
Use this document to deploy the SG-Link-200 for data collection. This includes
electrical wiring, mounting the device, and using SensorConnect software to
configure the node, start sampling, and display data.

3. Node Operational Modes
Sensor nodes have three operational modes: active, sleep, and idle. When
sampling, the node is in active mode. When sampling stops, the node switches
into idle mode, which is used for configuring node settings and allows toggling
between active and sleep mode. The node will automatically enter into sleep
mode after a user-determined period of inactivity. The node will not enter into
sleep mode while active.
Figure 7. Node Operational Modes
2. Mounting Recommendations
The SG-Link-200 may be mounted using the holes sized for M8 fasteners.
Stainless steel compression limiters are rated for up to class 10.9 bolts
Recommended installation torque is 20 Nm ± 2Nm.

6. 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 RTD-Link-200.
Figure 9. Node Discovered On Same Frequency
B. Automatic Node Discovery on Different Frequency
If a red circle with a number appears next to the Base Station, the node may
be operating on a separate radio channel. Select the Base Station and then
select the Nodes on Other Frequencies tile.
Figure 10. Node On Other Frequency
4. Install Software
Install the SensorConnect software on the host computer before connecting
hardware. Access the free software download on the LORD Sensing website.
http://www.microstrain.com/software
5. Establish Gateway Communication
Drivers for the USB gateways are included the SensorConnect software
installation. With the software installed, the USB gateway will detect
automatically whenever the gateway is plugged in.
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.
The gateway should appear in the Controller window with a communication
port assignment. If the gateway is not discovered, verify the port is active on
the host computer, then remove and re-insert the USB connector.

If the node was successfully added, two confirmation messages appear and it
will be listed under the Base Station.
Figure 13. Add Node Confirmation
If the node fails to add, a failure message appears. The node did not respond
to the base station which could indicate the node is not in idle mode or may
be on another frequency. If “Add Node Anyway” is selected, it associates that
node with the channel entered, but likely causes 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 14. Failure to Add Node
Highlight the new node being added and select Move Node to Frequency (#).
Figure 11. Move Node
C. Manually Add Node
Adding a node manually requires entering the node address and its current
frequency setting.

9. Radio Specifications
The SG-Link-200 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).

10. Battery Hazards
The SG-Link-200 contains internal, non-rechargeable lithium batteries. Lithium
batteries are a fire and explosion hazard. Do not store or operate the node at
temperatures above 212°F (100°C). Do not disassemble, short circuit, crush,
puncture, or otherwise misuse the battery.
Lithium batteries contain toxic chemicals that are harmful to humans and the
environment. Disposal is subject to federal and local laws. Do not discard the
battery or the node in the trash. Follow proper battery disposal protocol, or
contact LORD Sensing Technical Support for information on extracting the
battery or returning the product for proper recycling and disposal.
11. Power Supply
Apply only the input voltage range specified for the SG-Link-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. Failure to do so could result in
personal injury and permanent damage to the device.
