Spyder 3 CL User's Manual PRELIMINARY 39
DALSA 03-032-20008-03
• Test pattern successful— Run the svm 0 command to activate video. Then run the
gl command under both dark and light conditions to retrieve a line of raw video (no
digital processing). Under dark conditions, with factory settings, the analog offset
value should be within the specified range (refer to the user specifications). Adjust
the analog offset using the
sao command. Under light conditions, you should
receive a value.
Verify Voltage
Use the vv command to display the camera's input voltage.
Verify Temperature
To check the internal temperature of the camera, use the vt command. For proper
operation, this value should not exceed 75°C.
Note: If the camera reaches 75°C, the camera will shutdown and the LED will flash red.
If this occurs, the camera must be rebooted using the command,
rc or can be powered
down manually. You will have to correct the temperature problem or the camera will
shutdown again. If you enter any command other than
vt or rc, the camera responds
with:
Error 09: The camera's temperature exceeds the specified operating
range>
Verify Pixel Coefficients
Use the dpc command to display the pixel coefficients in the order FPN, PRNU, FPN,
PRNU… The camera also returns the pixel number for each fifth pixel.
End-of-line Sequence
To further aid debugging, the camera can generate an end-of-line sequence. The end-of-
line-sequence outputs "aa", "55", "line counter", "line average", "pixels above threshold",
"pixels below threshold". To activate the end-of-line sequence, use the command
els 1.
To disable the end-of-line sequence, use the command
els 0.
Use the
sut and slt commands to set threshold values between 0 and 255 for 8 bit data
modes, or 0 to 4096 for 12 bit data modes.
6.2 Specific Solutions
No Output or Erratic Behavior
If your camera provides no output or behaves erratically, it may be picking up random
noise from long cables acting as antennae. Do not attach wires to unused pins. Verify that
the camera is not receiving spurious inputs (e.g. EXSYNC if camera is in exposure mode
that requires external signals).
