# Configuring an ILM Anchor

## Groups

All ILM Anchors must be part of at least one group. Groups are used to optimize radio communication by helping the ILM Tool Tag find the best ILM Anchors for localization. Each group consists of between four and six 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.

For ease of use, assign the group numbers sequentially in relation to how the groups are located to each other.

## Coordinator

All groups must have one ILM Anchor assigned as a Coordinator. The Coordinator controls the radio communication between the ILM Tool Tags and the ILM Anchors and determines who should send information at what time. The Coordinator also controls information sharing to overhead systems, such as an MES, through Ethernet. A Coordinator can be shared by up to four groups. In special cases, a group can have two Coordinators.

## Coordinates/Distances

In case coordinates should be used (formerly known as Advanced mode) - with the possibility to see the live position of an ILM Tag in a coordinate system - all anchor positions needs to be measured and configured. This also allows for use of enable areas with rectangular or circular shapes.

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.
   Anchor Details pop-up window opens.

2. In the Anchor Details window, on the General tab, choose UWB channel from the UWB Channel drop-down list.

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

3. In the case coordinates should be 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.

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

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

   Each ILM Anchor must be part of at least one group.

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

6. In the Anchor Details window, on the Extended tab, choose the movement sensitivity from the Movement Sensitivity drop-down list. See Movement Sensitivity.

   This step is optional.

7. Close the Anchor Details window.

8. In the Configuration view, select Upload Configuration.
