PTP Timeout

In Emergent Vision cameras using PTP triggering, the PTP Timeout setting defines how long a camera waits for missing Sync packets before it flags lost sync and enters Listening mode.

If no Sync arrives within the chosen window, the camera switches its PTP status from Slave to Listening yet continues acquiring images.

How it works:

1. Each received Sync message resets the countdown.
2. If the counter reaches the PtpTimeout value, PTP Status drops to Listening.
3. Syncing resumes automatically when new Sync messages arrive.

Tip: Pick a PTP Timeout that’s short enough to warn you quickly when Sync messages really stop but long enough that the camera ignores the occasional dropped or delayed Sync message that can happen on a healthy network.

PtpTimeout node

• Access mode: Read/Write
• Node type: Uint32
• Range: 1 – 255 (step = 1 second)

You can use the eSDK API functions to:

• get and set the node’s current value, and
• get the node’s minimum and maximum values, and the node’s value increments.
