Can't Connect To Camera Device

Hello,

I recently purchased a camera for my EZ-B v4 controller, but I'm having trouble connecting to it. Every time I try to connect this error message displays repeatedly:

Code:

Camera Initialized: EZB://10.0.0.56:24 @ 320x240
ezbv4 camera image render error: System.ArgumentException: Parameter is not valid.
   at System.Drawing.Bitmap..ctor(Stream stream)
   at EZ_B.Camera.aJo6NxZbaD(Byte[]  )
   at EZ_B.EZBv4Video.o4twmdwIUb(EZTaskScheduler  , Int32  , Object  )
I'm connecting to the camera in Client mode and have made sure I'm including the proper port number as suggested in this post. I've also tried re-seating the board and the camera cable as suggested in this post. I'm not really sure what else to do, or what I may be doing wrong. Is there something that I am missing?

if you are using a ez robot camera , the cable goes bolt directions.
so if yours dont ,then you have a problem there.

Update: I was able to connect to the camera by wiggling the cables back and forth until the picture appeared. I guess the cable is just damaged :/

The white residue pictured on the camera is left over flux from the soldering process. It is non-conductive. If you have a cleaning brush and isopropyl alcohol you can clean it if you'd like but it's merely cosmetic and won't effect the function of the camera.

It's likely that there is poor contact between the camera cable and camera/ez-b. As Nomad suggested, with the power off, try repeatedly connecting and disconnecting the cable from the camera and ez-b to see if you can get a better connection. If the problem persists I'd recommend going to ez-robot.com and ask them for a replacement cable.

Naw, it's not salt, it's flux left over from the manufacturing process. I'm unsure about contact cleaner on a PCB as I've never used it before. Common Isopropyl alcohol that you get from your local pharmacy is non-corrosive, the higher the percentage of alcohol content the better. I use 90-99%.
