What is maximum frame rate on the 16-bit image stream from an A320 Camera?

In the 9 Hz version of the A320 Camera the maximum frame rate is 8 Hz.

 

For the full 30 Hz version we have found that we can guarantee 8 Hz provided that there are no limitations on the network.

The trick is to turn off some processes in the Camera and thereby lowering the CPU load so it has more time to deal with the 16-bit streaming process.

Following settings commands in the Camera before turning on the image stream are recommended:

 

rset .image.contadj.adjMode manual
rset .image.sysimg.measureFuncs.spot.1.active false
rset .image.sysimg.measureFuncs.reftemp.1.active false

Setting commands can be controlled by using Telnet, SDK or the LabView Toolkit or true Resource socket connection.

 

Image grabbing and streaming is handled by the Camera micro-controller, so the fewer tasks that the software has to handle, the higher priority the image streaming gets.

In case you have selected a down sampled image format (160 x 120) you will of course only reach 9 Hz for the 9 Hz camera but more for the 30 Hz camera.
