1 Tap Sequential
” – In this mode all pixels (for every line) are sent to one
output (Tap 1) in a sequence, starting with the first and ending with the last (L)
pixel (1, 2, 3, … L-1, L) – Figure 2.23. Each pixel can be 8, 10, 12 or 14 bit
deep.

Dual Output Cameras
For the dual output cameras (B0620, B1620, B1920 and B2520) there are several
options available, since the camera can work in a single or in a dual output mode and
can have a color or monochrome imager. In a single mode (not available in B2520)
operation for the camera with monochrome imager the user has only one option – 1
Tap Sequential. If the camera has a color imager and is in a single mode, user can
select the raw Bayer data output (1 Tap Sequential) or the interpolated color – 3 Tap
RGB. For Dual mode of operation regardless of imager type (mono or color) the user
has two choices – 2 Tap Sequential or 2 Tap Interleaved. 3 Tap RGB is not available
because of bandwidth limitations for Base Camera Link

“
2 Tap Sequential
” – In this mode all pixels are sent to two outputs (Tap 1 and
Tap2) in the following sequence – Figure 2.24a. Each pixel can be 8, 10 or 12
deep (14 bit output is not available in this mode). This feature is custom and it is
not implemented in the camera, please contact IMPERX for more information.

Tap 1 – starting (for every line) with the pixel 1 and then all pixels in a sequence
(1, 2, 3 … M-1, M) until reaches the middle pixel (if the CCD has 1000
pixels in one line, the middle pixel M is #500.
Tap 2 – starting (for every line) with the pixel M+1 and then all pixels in a
sequence (M+1, M+2, M+3 …L-1, L) until reaches the last pixel for the
line.
