PL-X Cameras
Description:
FEATURE_PTP allows 2 or more cameras on the same network, to synchronize their clocks to a ‘Master’ clock using the IEEE1588 / PTPv2 protocol. Pixelink cameras are capable if becoming the master clock on the network, as negotiated via the PTP protocol. An application gets timestamps from a cameras clock via the function PxLGetCurrentTimestamp. What more, a camera timestamp is also returned in the descriptor of each frame received, and with certain other operations, such as event callbacks.
API Control:
| Feature | Number of Params | Parameters | Units | Restrictions |
FEATURE_PTP | 4 | FEATURE_PTP_PARAM_MODE | N/A | Integer Only |
FEATURE_PTP_PARAM_STATUS | N/A | Integer only | ||
FEATURE_PTP_PARAM_ACCURACY | Read only | |||
FEATURE_PTP_PARAM_OFFSET_FROM_MASTER | Read only |
Note: On reads (PxLGetFeature), all 4 parameters will be valid. However, on writes (PxLSetFeature), only the FEATURE_PTP_PARAM_MODE parameter is settable. See PTP Mode for available PTP modes.
