Troubleshooting

7 Troubleshooting

7.1 Problem 1: EN Setup Software Does Not Find Any Camera in the Network

1. Make sure that your host PC and EN cameras have the same subnet address, and that their IP

addresses are not identical. If the EN camera’s IP address is 192.168.30.65, then you should not set

the same IP address to the host PC.

2. If you have a firewall set up on your Windows computer, disable it. Also, be sure to enable network

data transfer of the EN setup software.

3. If the EN camera’s IP address is unknown, use the RS-232 debug cable. For more information,

please see Section 2.2.2 (b on page 4.

4. If the EN camera is set to DHCP client mode, then you need DHCP server in your network. Other-

wise, a valid IP address is not assigned to the EN camera.

7.2 Problem 2: EN Setup Software Found the Camera, But the Video Image is

Too Dark or Just Black

1. Make sure that the iris of the lens is open. If the light sensor is connected, then it is controlling the

camera parameters such as shutter, gain, white level (vtop) and black level (vbot). If the light sen-

sor is set up outdoors and the EN camera is set up indoors in the daytime, then the image will look

very dark, because the camera parameter is probably set to the highest shutter (1H exposure time),

and lowest gain (Gain=min, Vtop=max, Vbot=min).

2. If you want to manually set camera parameters instead of light sensor control, you can do so by

using EN setup software. In Video control window, right-click on the camera icon. Select “Manual

Video Adjust.” Set appropriate camera parameters manually. See Figure 6.2, “Asynchronous

Reset,” on page 36 for details about the camera parameters.

7.3 Problem 3: TTL Trigger/Ethernet Trigger/Serial RS-485 Trigger Does not

Generate Trigger

1. Make sure that the “Trigger” register is set properly to enable TTL Trigger/Ethernet Trigger/Serial

RS-485 trigger. In the “Properties” window of the EN setup software, you can read/write “Trigger”

2. If you choose dataID source to be RS-485 or Ethernet, make sure to send dataID within the pre/post

message time window defined in those registers. If there is no dataID or the dataID is sent after or

before the predefined window, then the trigger will be rejected as an invalid trigger. Make sure that

you set the appropriate time pre/post message time window. The factory default setting of dataID

source is self-generate mode.

3. If the TTL trigger is noisy, then pre/post trigger condition filter may reject the trigger input to the

camera. TTL trigger must stay stable for a certain predefine pre-time before the trigger edge and

post-time after the trigger edge. If not, then the trigger will not be generated. The factory default of

pre- and post-time trigger is 1ms.

4. If TTL trigger pulse is noisy, then the trigger noise filter may reject the trigger input. TTL trigger

pulse width smaller than pre-defined trigger filter time is ignored automatically by the FPGA as

noise. The trigger noise filter factory default setting is 100us.
