Interlace problems with Pulnix tm-6710

[Vestibularis]

I just got the Pulnix tm-9710 and NI 1422. Two major problems occured:

1. The acquired images are interlaced. In Measurement & Automation Explorer I can choose to let the camera work in non-interlaced mode, but when trying that there is just a time-out error. This is a non-interlaced camera, right?

2. The serial camera control does not work. When I try to making changes in the software, the respons I get is a communication error.

Anyone know these problems?

The Camera File and MAX are set to interlaced in order to get the pixels read into the correct location in the image. The frame that you are getting should actually be progressive in that all of the lines of the image are taken at the same time. I don't know exactly what the issue with the serial is. Are you changing the attributes in MAX and getting this error or are you using a serial utility from Pulnix? I would verify that you have the correct cable as well.

But I don't get any full frames. What I acquire are these interlaced fields. Shouldn't I be able to acquire full non-interlaced frames (640x480) at 120 Hz with my equipment (Pulnix TM-6710 and NI 1422)?

I attach an image to examplify the images I get when using the Camera File and MAX with no property changes. This isn't what they should look like, right?

Thank you for the help!

No, that isn't what the image should look like. I'm assuming that in MAX you have the camera set to Interlaced, which is correct in order to get the data read in correctly. Since you get black lines for every other line, I would say that the frame grabber is trying to get a whole frame but either the camera isn't giving it or the cable is incorrect. The camera has two "taps", or two sets of data lines which actually send two pixels to the frame grabber at a time. One tap is the even lines of the frame and the other tap is the odd lines of the frame. Attached is the pinout for the TM-6710, please verify that all of the connections are the same.

Thank you for the pinout. The pin-connections on the cable I got from Pulnix was totaly incorrect. I'm surpriced that even every other line was acquired.

The pinout you provide is incorrect! It's only for the PCI-1424. Can you send me the pinout for PCI-1422?
