This document is a master document for all AVT GigE camera models and is NOT camera specific
PvAPI users see tPvFrame. AncillaryBuffer.
Ethernet
DeviceEthAddress – String – R/C
The physical MAC address of the camera.
HostEthAddress – String – R/C
The physical MAC address of the host network card.
IP
DeviceIPAddress – String – R/C
The current IP address of the camera.
HostIPAddress – String – R/C
The current IP address of the host network interface.
GvcpRetries – Uint32 – R/W
Gvcp = GigE Vision Control Protocol. The maximum number of resend requests
that the host will attempt when trying to recover a lost control packet.
The user can set the value but internally it is overwritten to 5 for PvAPI v1.26.
Gvsp
Gvsp = GigE Vision Streaming Protocol
[Byte7]These 8 bits indicate the current aperture position of the EF lens in Dn. To convert Dn to FStop
value, use formula: FStop = 2 (Dn – 8) /16.
[Byte 8] These 8 bits indicate the current focal length of the EF lens in mm.
[Bytes 9 – 12] Exposure value in μs.
[Bytes 13 – 16] Gain value in dB.
For GT1930L and GT1930LC cameras: Gain value in tenths of dB (i.e. 201 represents 20.1 dB)
[Bytes 17 – 18] Sync in levels. A bit field. Bit 0 is sync-in 0, bit 1 is sync-in 1, etc. A bit value of 1 = level
high, and a bit value of 0 = level low.
[Bytes 19 – 20] Sync out levels. A bit field. Bit 0 is sync-out 0, bit 1 is sync-out 1, etc. A bit value of 1 =
level high, and a bit value of 0 = level low.
[Bytes 21 – 24] Reserved. 0
[Bytes 25 – 28] Reserved. 0
[Bytes 29 – 32] Reserved. 0
[Bytes 33 – 36] Reserved. 0
[Bytes 37 – 40] Reserved. 0
[Bytes 41 – 44] Chunk ID. 1000
[Bytes 45 – 48] Chunk length.
