Why is sensor data missing or incorrect with Lord MicroStrain G-Link-200 Network Hardware?

  First, check the power and connections to both the node and gateway, ensuring they are on and communicating with the software. You can verify node accessibility through the configuration menu. If the sampling mode, rate, or duration seem off, adjust them in the node configuration menu. Confirm that sampling has actually started by checking for the sampling mode next to the node name; if not, activate it in the software. Also, verify the sensor connections and wiring. Ensure the sensor is configured on the correct channel and enabled for data acquisition. Note that internal sensors are factory calibrated and typically do not require adjustments.

  First, ensure the device is turned on; the status indicator LED should light up. If the node still doesn't power on, the battery might be dead and need replacement. If power settings and connections are all correct and the node remains unresponsive, it may be damaged.

Why is there a red LED on startup of my Lord MicroStrain G-Link-200?
- J
  Joshua BerryAug 27, 2025
  If a red LED appears when starting up your Lord MicroStrain Network Hardware node, try removing the batteries for more than 10 seconds, then re-insert them. If the red LED persists, replace the batteries with three new ones. If the red LED continues to appear after replacing the batteries, the node may be damaged.

How to fix communication issues with Lord MicroStrain Network Hardware gateway or node?
- C
  Connor KimNov 4, 2025
  First, make sure the node and gateway have power and that the power switches are turned on; a status indicator LED should be illuminated on both. Next, verify gateway communication within the software, checking and reconnecting all communication and power cables. Ensure the node isn't sampling or sleeping by observing the node status indicator LED. If it is, use the 'Set to Idle' command to allow configuration. If the issue persists, perform a bench test to ensure the node is within range of the gateway. If the node isn't in normal boot mode (indicated by the status LED), cycle the node power rapidly three times, then power it on normally. If problems continue, verify all connections, power, and settings. If you have other nodes and gateways available, test them one at a time to identify a...
