# Configuring an ILM Anchor

Before configuring an ILM Anchor, find all ILM devices.

1. In the Configuration view, on the Anchors tab, select the ILM Anchor, then select Edit.

   The Anchor Details window opens.

2. In the Name box, enter a name for the ILM Anchor.

   This is optional in ILM Manager 3.10.

3. In the Anchor Details window, on the General tab, choose UWB channel from the UWB Channel dropdown list.

   All ILM Anchors must be on the same UWB channel as the ILM Tool Tags.

4. If case coordinates are used, enter the measured position of the ILM Anchor in the X (m), Y (m), and Z (m) boxes.

   All ILM Anchors on the same UWB channel that are close to each other must share the same Right-handed Coordinate System.

5. In the Group boxes, enter the group numbers that the ILM Anchor is going to be part of.

   Each ILM Anchor must be part of at least one group. Groups are used to optimize radio communication by helping the ILM Tool Tag to find the best ILM Anchors for localization. Each group consists of 4–6 ILM Anchors. It is not recommended to have more than six ILM Anchors in a group. An ILM Anchor can be part of up to four groups, with each group having a group number between 1 and 255.

   The coordinator group IDs must be arranged in numerical order as they are placed along an assembly line. After group IDs have been rearranged, use ILM Manager to reboot the anchor.

   The group number can be any integer between 1 and 255.

6. In the Anchor Details window, select the Coordinator checkbox if ILM Anchor is going to be a Coordinator.

   All groups must have one ILM Anchor assigned as a Coordinator. Coordinators are responsible for synchronization of radio communication and can forward information via the network. A Coordinator can be shared by up to four groups. In special cases, a group can have two Coordinators.

   For consistency, all Coordinators should be on the same side of a production line.

7. In the Anchor Details window, on the Extended tab, choose the movement sensitivity from the Movement Sensitivity dropdown list. For more information, see Movement Sensitivity.

   This step is optional.

8. Close the Anchor Details window.

9. 9. In the Configuration view, select Upload Configuration.
