Thanks for the information. I was able to change the exposure time in the GUI and easily get the 30 fps

By default camera has autoexposure turned on, so it increases the exposure time (up to the default limit of 500ms) if it is too dark, and frame rate can never get higher than 1/Texposure. You may decrease that limit (i.e. in the camera GUI) to lower value and increase analog gain (default is 2.0, can get up to 15.75 but in that case there will be no room for white balancing). You may easily see if the frame rate is limited by exposure - in the camera GUI http://wiki.elphel.com/index.php?title=File:Controls_with_blank.jpeg there is frame rate indication near the top (2.5fps on the picture). If it is green - the exposure is limited by the sensor/compressor (not a very good example on the screenshot - such low fps is caused by external camera synchronization, free running camera should have 10.8 fps in JPEG and just under 15 fps in JP4 mode). If the fps color changes to red - the exposure is a limiting factor. If you have a low power computer/graphic card it can also limit the frame rate. You may try mplayer rtsp://192.168.0.9<http://192.168.0.9> -vo null to test the frame rate without displaying images - in that case the indicated frame rate will match the incoming stream.

Attached is a text file of the output of the serial port at bootup. We would like to set the camera up for 1280X720 image size at 30 fps. I was able to set the image size thru the Camera Interface, but I'm only seeing ~3 fps. What is the best way to setup the frame rate to be 30 fps, or is this some kind of limitation due to my Ethernet setup thru a switch box?

But I'm still curious about the serial port console - did you make it work? What kind of output are you getting there?

How did you do that? What was it exactly there? What happens on the serial port now?

I just wanted to see if I could hook up thru the serial cable at the baud rate 115K and I could. Later in the day, I could no longer communicate via the Ethernet, so I power cycled. Since then nothing has worked. A couple of days ago, when I powered up the camera, it took three power cycles before the Ethernet communication started working. So I'm not sure what happened. Possibly a hardware issue?

I power cycled the camera and now we can not communicate to it thru Ethernet or the Serial cable connected to the 10369 IO board. Diana, you wrote that the serial cable was connected to the camera. Before you lost communication with the camera - did you configure some terminal emulator (i.e. minicom) to see camera boot messages on the system console? If yes - what happens now on that port? The baud rate on the port is 115k. Andrey Prior to power cycling the camera we could communicate and run video and camera applications. The Ethernet green and yellow lights are blinking, and the light on the power supply is green. Any suggestions?
