IN PROGRESS
My early posts were often quite brief, and some of the explored techniques were never returned to despite my intentions.
A shawl tale was written in 2009.
The designs explored in this post can be found in the Passap Duomatic baby book. 
A closer look:
My attempt at a hand technique at that time,
and the declaration of a planned challenge, “creating a downloadable stitch pattern that will automatically select appropriate needles and duplicate this texture.” It only took 16 years!
The pattern chart:
on the Japanese machines, the beds are reversed.
The back bed = ribber in our case, is set to knit every row.
Locks is the Passapese for carriages.
Many patterns can be achieved by lock settings and arrow keys without added programming. In Brother machines, a small cousin of the function is found in the use of lili buttons.
When an arrow key is pressed, it tells the Passap machine to engage the pushers. Depending on the direction of the movement of the locks, the pushers will be lifted or pushed down. Their initial position is set up manually.
The left arrow key changes pusher selection when the locks move to the left.
The right arrow key changes pusher selection when the locks move to the right. Use of both arrow keys simultaneously will change the pusher selection every row.
With the Zero key, no arrow selected, the pushers do not change their position on that pass, repeating the selection.
Pushers preselect for the next pass, as happens with needle preselection in Brother.
AX is the tuck setting for Passap, pushers selected up knit, selected down tuck.
When setting up these patterns, it is best to have a needle on the ribber on each side, not observing the usual “needle rule” for rib knits.
When working on both beds, the default illustrations have a space > dot between needles in work to permit the illustration of needles between them on the opposite bed, so the chart is not for an every other needle design. In this instance, stitches > needles in work occur in pairs on the top bed.
Programming the repeat: the first pass will knit or tuck alternate pairs of stitches.
The needle selection then stays fixed for 3 rows and reverts to the first selection, a 4-row design. Stitches will be tucked side by side, breaking another common rule.
The ribber needles in this case are extra, not transferred down to the ribber from the knit bed as in some of the fabrics recently explored in other posts.
They are brought into work between pairs of knit stitches on the top bed, represented by the red lines in this chart.
Because of their location, the ribber should be set for half pitch.
With use the beds can shift, for tips on ribber alignment please see post:
A bit on ribbers: Japanese KMs, alignment, and symbols 1.
The stitches on the ribber are outlined with cyan, the triple tuck loops as those needles are brought forward on the knit bed for knitting with white.
The proof of concept, programmed on 46X24:
The darker color was thicker, knit well, but since this was a test, seeing stitch formation while checking for accuracy mattered. Testing the pattern on the knit bed first determines any problems with the design before the ribber is brought into work, limiting visibility as the knit progressed.
The same repeat, with stitches transferred down to the ribber, leaving empty needles on the top bed, knit on every other needle with 2/8 wool, produced an interesting texture, but quite a narrow knit, 3.5 inches wide. 
Racking on EON rib: some considerations.
A different design, with the repeat cut in half widthwise for a more traditional tuck stitch configuration,
also with stitches from the ribber between stitches on the main bed
a knot in the yarn knit right through and was missed, easy to do when working double bed if the yarn travels with no hesitation
This design uses a simple racking pattern, easy to execute in thin yarns, but not as impactful. 
In Brother the ribber performs the racking movements.
Both beds are set for plain knit.
The needle set up is on half pitch.
Cast-on for the test swatch was with the racking position starting on 8, with the plan to rack to 10, knit 2 rows, rack back to 8, knit 2 rows, and repeat, performing all position changes with the carriages on the left.
The yarn used is a 2/18 wool/silk blend that resisted the technique regardless of tension and weight adjustments, and began breaking, but there is enough knit to visualize the result. 
Pattern 2053
is for reversible checkerboards that use tuck settings on both beds,
The strippers in the Passap system help push down on loops and knit stitches, anchoring them in a way simply not possible in Brother models. Even if a choice were to be made to push down between the beds with a hacked tool, the Brother needle preselection renders that impractical.
The concept behind the Duomatic version is then switched to automated patterning with the tuck setting on the main bed, and the ribber set to knit every row.
The two rows with one arrow key result in the repeat shifting locations by repeating the same selection, as seen in this chart
The 8X40 design was knit on 48 stitches, these knits are quite wide, loose bind off are required when the pieces are completed.
Each sample knit measures 11.5 inches in width.
Where 4 side by side needles are tucking for four rows, the stitches on the ribber may have a tendency to jump off, resulting in loops not being anchored, so those areas require special attention. The proof of concept for the above repeat in one color and then with color changes every 2 rows
More variations including racked ones are explored in Fisherman_ English tuck stitch rib 1_ checks patterns_ Brother, Passap.








A comparison to the mirrored original inspiration, likely knit in thicker yarns
The knitting process: with any textured or very lacy knits casting on and binding off require special consideration.
Read the first row of the pattern, cam set to KC1 to ensure end stitches are knit when patterning occurs only on the top bed.

The repeat is 8X8 and the above movement can be seen in the purl view.
A spreadsheet table may be created to help with tracking multiple series of cables across a knit and their direction. It can contain as little or as much information as one wishes. Included here: the RC for possible crossings, and their direction on the purl side for machine knitting (reversed for hand knitting). Columns may be added including how many needles are left in or out of work between cable knit spaces or other info. 




Which leads to the topic of creating shapes by combining the repeats
A brief effort containing at least 5 errors leads me to wonder about programming needle selection to help track crossings more easily and avoid mistakes. The center ladder here was latched up during knitting. 

If the start is on the top bed, stitches on the ribber may be created by picking up bars from the top bed
the yarn above was a 2/8 wool, which refused to cable on the ribber, and having the crossing was preferred to not
changing to a thinner wool-silk solved the problem. 
In reviewing the post after linking to it here I realized the now marked punchcard error at its top. The amended longer chart reworked in Numbers is also added to the older post. It is shown here aside from its tiled chart, checking for alignment, a habit developed as my skill and comfort in using spreadsheets grew, 
It is possible to use the repeat working 1 X 2 stitch crossings for a very different look.
Assigning colors to crossings in a chart may be helpful or too much info depending on one’s perspective, the bottom of the repeat is on the right. 

In my first test crossings occur on both beds and on the same row. Even using the thinner blue yarn at maximum tension the transfers were hard to execute. I had more success when I added 2 empty needles between the vertical ribs and brought one on each side of each rib into work on the top bed prior to knitting the last row between transfers, creating a bit of extra yarn to ease the crossings.


Trying out a simple repeat in smaller rib configurations will provide some idea as to whether the technique falls into the love of or not something to do simply because one can.
The step-by-step instructions apply to both instances: the chart shows 4 rows knit between crossings, instead, here 6 rows are knit in both tests.
the rib configuration set up
1. after 5 rows knit, bring an extra needle in work on the top bed to pick up extra yarn for the cross
2. drop the extra loop, make certain the empty needle returns to A position
3. transfer all cable ribber needles to top bed
4. cross the stitches with two three-prong tools
5. transfer stitches back down to the ribber
knit 5 rows, repeat steps 1 to 5.
An attempt at a larger swatch using 1X1 ribs:

the cable crossings using it were impossible, starting over with a thinner yarn at the same tension
the ribber may be dropped after transfers up to the main bed, keeping stitches and crossings visible, making it possible to make corrections in any cables if they are needed before re-engaging the ribber and transferring stitches back down 

In the above swatches, when any transfers were made to the top bed, after crossings, a row was knit before returning stitches to the ribber. The extra row may or may not be noticeable, depending on the yarn and colors used.
The number of rows between crossings can vary. When the crossing row is reached:

Assigning colors to columns reveals that stitches are not moved onto the same stitch type when moved over a single, undisturbed, fixed center stitch.
Shifting the needle arrangements when cabling, moving across a center column of two stitches that remain fixed on the main bed, the cable direction as it would appear on the purl side on the left, the knit side on the right is straightforward here:
I found the above impossible to knit, even with ladders for extra slack, and the swatch stopped when the yarn broke 
There appears to be enough slack produced in the formation of stitches between beds to make the planned crossings possible.
From a Brother pub, small crossings for a smocked effect 

Adding and removing rows in the tables or even changing colors is easy and quick in a spreadsheet, tiling in repeat with scaled screengrabs provides a quick reference for possible improvements/corrections before any actual knitting takes place 






























the punchcard change knob has selections for single motif and pattern knitting (KC)

















































looking at charting differently, back to Excel: single repeat
