1) Access RTLS Manager

• Open RTLS Manager in RTLS Studio.
• Ensure all anchors are automatically added.
• If any anchors are missing, check their RTLS Server IP Address settings by directly accessing the anchor.

2) Verify Unique IP Addresses

• Confirm that all anchors have unique IP addresses to avoid conflicts.

3) Set TDMA Protocol to UDP-SAD

• Navigate to Anchors (Basic) → Settings.
• For each anchor, set the TDMA Protocol to UDP-SAD using the dropdown at the top of the column.

4) Update Settings

• Click the Update All button to apply the changes.
• RTLS Studio will automatically select the required broadcasters and coordinate synchronization periods.

5) Verify Configuration

• Check the Status Bar in RTLS Manager to confirm the correct configuration of UDP-SAD.

6) Check Synchronization Stability

• After initialization, verify that all anchors are present and properly synchronized under Synchronization Stability.

7) Verify Tag Data

• Navigate to Tag Summary to confirm that blinks are being received from tags.

8) Confirm Synchronization

• Once all anchors are present and receiving blinks, UDP-SAD synchronization is successfully enabled and anchors are fully synchronized.

Configuring Global Settings for UDP-SAD Synchronization

The Anchor Synchronization menu in RTLS Studio provides the following global settings to fine-tune synchronization for UDP-SAD:

1. Subnet Timeout: Helps manage synchronization in high-latency networks.
2. Subnet Guard: Optimizes inter-subnet positioning by preventing collisions during synchronization.

Subnet Timeout

• Default: 8ms
• Purpose: Determines how long the RTLS Manager waits for the current subnet to acknowledge synchronization before moving to the next subnet. This setting is crucial for handling packet loss (UDP) or high network latency.

When to Modify It:

• • If synchronization requests frequently time out.
  • To prevent collisions caused by RTLS Manager moving to the next subnet before the current one is fully synchronized.

How to Modify It:

1. 1. Measure the network latency (e.g., using ping) to detect the round-trip time.
   2. Double the latency value to account for delays (e.g., if latency is 20ms, set Subnet Timeout to 40ms).

Subnet Guard

• Default: 10ms
• Purpose: Ensures smooth inter-subnet positioning by setting a buffer time to avoid collisions between synchronization periods.

When to Modify It:

• • If network latency increases and inter-subnet positioning is required.

How to Modify It:

• • Set Subnet Guard slightly higher than Subnet Timeout (e.g., 10ms for a Subnet Timeout of 8ms).
