The Sewio anchors have stopped operating
Last updated: Aug 24, 2026
- Open the RTLS Manager we portal. If it is off-line, check if the Sewio PC is switched on and if the cable between the Sewio PC and TrackLab PC is correctly plugged in. If the problem persists:
- In RTLS Manager/Anchors Summary, check if all anchors are listed, and if the status shows they are online. If an anchor is missing from the list, proceed with step 4. If the anchor 'status' column indicates they are off-line, proceed with step 3.
- In RTLS Manager/Anchor Settings, check if the IP addresses are still correct for each anchor. Normally, the anchors will have a static IP (recommended!) but if it is set to DHCP and the system is connected to the company network, IP addresses may have changed.
- In RTLS Manager/Synch Stability, check in the graph if the values on the y-axis don't exceed a value of "2". In the slave-anchor list, check that there is no packet loss (the number of lost packets must not increase over time). If either NOT ok, proceed with trouble shooting. If this does not solve the problem, proceed as follows:
- Visually inspect the anchors, to see if the housing shows an LED lighting up. If indeed the case, proceed with trouble shooting.
- Visually inspect the anchors to see if they are misaligned (due to any impact of for example a bird, a door, machine) or if any new big objects were introduced in the tracking area, which can potentially block the line of sight between the master anchor and its slaves. If the problem persists:
- Check the cables, connectors and network switch. Are all cables plugged in correctly (try unplugging-plugging)? Is there water or dust ingress? Are all LED's on the switch lighting up? If not, try plugging the connector into a free switch port. Does the network switch have a correct IP rating? Also check the cable between the switch and the Sewio PC. You could optionally use a UTP cable tester (available online for app. $10,-) to test the cable integrity. If the problem persists:
- Use the backup tool to make a database backup and get R&D assistance.
- See also the anchors FAQ on the Sewio documentation portal.
- If none of the above solved the problem, start an RMA process.
