MicroStrain, Inc. Common Terms These terms are in common use throughout the manual: • • • • • • • • • • • • • • • Address: Each node has a unique address from 1 to 65534 which identifies the node to the base station and software. Base Station: The transceiver base station attaches to your host computer and provides communication between the software and the node(s). Bits: The digital equivalent of voltage on the node. The node excites all sensor circuits with +3 Volts.
MicroStrain, Inc. • • • • • • • • • • • Node: The node is the wireless transceiver that carries the sensors and provides communication with the base station. The G-Link®, V-Link®, SG-Link® and TC-Link® are all nodes. Ping: A byte is transmitted by the base station to a particular node and the node responds by echoing the byte indicating communication exists between the base station and the node. Plugins: Software ‘wizards’ which aid in the configuration of the node’s sensors.
MicroStrain, Inc. Operation Let’s discuss the operation of the SG-Link® OEM and base station in conjunction with the Agile-Link™ host software. The SG-Link® OEM has a differential input channel (strain channel), a single ended input channel (analog channel) and an on-board temperature sensor channel. The SGLink® OEM samples these three channels using four different selectable methods.
MicroStrain, Inc. In the STREAMING sampling method, the SG-Link® OEM sampling rate is directly dependent on the number of sensor channels which are active. With 1 channel active, the channel will be sampled at a rate of 736 samples per second; with 4 channels active, each channel will be sampled at a rate of 565 samples per second. Streaming duration can be finite or continuous. In finite streaming, a sampling duration is set and the streaming session will last the duration once initiated.
MicroStrain, Inc. In the Datalogging sampling method, you may trigger a datalogging session on any number of SG-Link® OEMs at the same instant by broadcasting a datalogging command from one base station to all the nodes. In this case, all nodes and the base station operate on the same frequency. All nodes would receive the command and independently perform their datalogging session. Each node would be downloaded separately.
MicroStrain, Inc. Agile-Link™ Base Station manual which is contained on the Agile-Link™ CD and on our web site for detailed instructions on its use with SG-Link® OEM . The SG-Link® OEM has an additional datalogging feature which we describe as Sensor Event Driven Trigger (SEDT). In SEDT, the SG-Link® OEM may be configured to commence datalogging automatically each time a “ceiling” or “floor” sensor output is met.
MicroStrain, Inc. Base Stations The SG-Link® OEM is designed to operate with any of the Agile-Link™ wireless family base stations. These base stations include the USB base station, the Analog base station and the Serial base station. Please refer to the Agile-Link™ Base Station manual which is contained on the Agile-Link™ CD and on our web site for detailed instructions on their use with SG-Link® OEM.
MicroStrain, Inc. nodes including ping, datalog, stream data, erase, read and write EEPROM, etc. The Analog base station in turn receives acknowledging responses from the nodes and passes datalogging downloads, streaming data, high speed streaming data and low duty cycle data to the host computer. The Analog base station is capable of maintaining communications with multiple nodes. Its broadcast mode allows the simultaneous issuance of several commands to multiple nodes.
MicroStrain, Inc. Differential Input Channel The SG-Link® OEM has one differential input channel. This channel is designed to accommodate strain gauges with 350 ohm resistance or greater. The SG-Link® OEM by default is configured to support a full Wheatstone bridge installation. The SG-Link® OEM can also be ordered from the factory configured to support half and quarter bridge installations. It is important to know how your SG-Link® OEM has been configured before proceeding with use.
MicroStrain, Inc. Board, a precision instrument designed and manufactured by MicroStrain, incorporates a selectable bridge configuration (full, half, quarter) coupled with a precision shunt resistor to test the differential input channel and a 0-3 volt photocell to test the single ended input channel. Each starter kit is shipped with a Tester Board and a detailed Tester Board Quick Start Guide.
MicroStrain, Inc. Connecting a quarter bridge strain gauge This example assumes the SG-Link® OEM is configured with the optional internal quarter bridge completion resistors. If not, the completion of the bridge (shown as internal circuitry) must be completed externally. The three wire arrangement is recommended in order to cancel thermal effects of the lead wire resistance (RL). It is strongly recommended that shielded wiring be used, as this can significantly reduce system noise.
MicroStrain, Inc. Connecting a half bridge strain gauge This example assumes the SG-Link® OEM is configured with the optional internal half bridge completion resistors. If not, the completion of the bridge (shown as internal circuitry) must be completed externally. It is strongly recommended that shielded wiring be used, as this can significantly reduce system noise. Please note that the shield of each cable must be grounded at one location only, to prevent the occurrence of ground loops.
MicroStrain, Inc. Connecting a full bridge strain gauge This example assumes the SG-Link® OEM is configured with the optional internal full bridge completion. In this arrangement, the user is responsible for all bridge completion. It is strongly recommended that shielded wiring be used, as this can significantly reduce system noise. Please note that the shield of each cable must be grounded at one location only, to prevent the occurrence of ground loops.
MicroStrain, Inc. Programmable Gain As indicated in the Differential Input Channel section, the SG-Link® OEM has a userprogrammable gain that allows the bridge circuit to be amplified to suit the characteristics of the particular strain gauge in use; this programmable gain can be set from 20 to 2560. Note: In the current Agile-Link™ software, the gain must be applied through the Read/Write EEPROM. The gain can not be applied through the Channels tab in the Configuration window as normal.
MicroStrain, Inc. Single Ended Input Channel The SG-Link® OEM has one single ended input channel. This channel will accommodate most 0-3 volt DC analog output sensors including accelerometers, pressure sensors, geophones, temperature sensors, inclinometers and the like. The SG-Link® OEM can provide +3 volts DC up to 50 mA to the sensor. Alternatively, the sensor can be powered with +3 volts by any external constant source.
MicroStrain, Inc. selectable bridge configuration (full, half, quarter) coupled with a precision shunt resistor to test the differential input channel and a 0-3 volt photocell to test the single ended input channel.

This terminal strip accommodates the differential input channel sensor connection, the single ended connection, and an external power connection. 8 Figure 5 Pin Number 1 2 3 4 5 6 7 8 Pin Name Vxc S+ SGND Sense Ain GND Vinput Pin Description 3.0 volt sensor excitation. Positive input to the differential amplifier.
MicroStrain, Inc. Device Status LED The SG-Link® OEM has an LED indicator near the edge of the front face at DS1. The LED signals the various operating states of the SG-Link® OEM to the user. Figure 6 When the SG-Link® OEM is switched on, the green Device Status LED will rapidly flash several times and in a moment, begin ‘throbbing’ on and off every 1 second. The rapid flashes indicate a successful boot-up. The ‘throbbing’ indicates that the SG-Link® OEM is active and in an idle state.
MicroStrain, Inc. Radio and Antenna The SG-Link® OEM and its base station employ a 2.4 GHz IEEE 802.15.4 compliant radio transceiver for wireless communication. The radio is designed to comply with with ETSI EN 300 328, EN 300 440 class 2, FCC CFR-47 part 15 and ARIB STD-T66. For additional information on regulatory approvals, please see Appendix. The SG-Link® OEM can be factory configured with one of two antennas - a compact surface mounted monopole antenna, or a whip monopole antenna.
MicroStrain, Inc. Node Addressing Each node has a unique address from 1 to 65534 which identifies the node to the base station and software. Typically, the factory assigns the last 4 digits of the node’s serial number as the address, and changes to this address are not recommended except under special circumstances. Address 65535 is a specialized broadcast node address. For example, if several nodes hear a command for node 65535 to start datalogging, they will all initiate datalogging simultaneously.
MicroStrain, Inc. Sample Duration Calculations Datalogging, streaming, low duty cycle and high speed streaming sampling sessions can all be set to last a finite duration, a finite amount of time. Finite sample duration is a value ranging from 100 to 65500, in increments of 100. A datalogging example: We set the number of active channels to 3. We set the sample rate to 32. We set the sampling duration to 1000. We trigger the session. We download the session.
MicroStrain, Inc. Time Stamping The SG-Link® OEM node and Agile-Link™ software handle time stamping of datalogging, streaming, low duty cycle and high speed streaming data in different ways.
MicroStrain, Inc. Power The SG-Link® OEM may be directly powered by external batteries, external regulated power supply or other external source. The source should deliver stable voltage, must range between +3.2 to +9.0 volts DC, and must be capable of sourcing at least 50 mA. The power must be applied through the wiring terminal strip; pins 4 or 7 GND and pin 8 Input Power (see Terminal Strip section of this manual).
