Holy shit.....
Previous DFP cable extensions didn't work (not well, at any rate), dfp-dvi adapters didn't work (with DVI cables as the extension), dfp gender changers/hardware almost don't exist..... DVI cables seem to be pinned every way to sunday. And even if they were pinned "correctly", the dfp-dvi *adapter* is hobbled from the gitgo because my dfp cables are 26 pin, and DVI cables (dual link) are 24 pin, so even with the "proper" adapter, you are short 2 pins. And then, there is *at least* one dummy pin on dvi cables, sometimes 10 dummy pins.... So at best, you are short 3 pins, and there is no way of telling what those missing pins are doing/not doing.
I was actually at the Microcenter pyooter store, with my dvm, ringing out various dvi cables for their dummy pins, finally concluding that dvi cables were simply not going to work as a substitute for 26 pin dfp cables.
The 30 ft dfp replacement cable (nonHaas) worked, but yielded a significantly degraded image, and the dvi's yielded, well, NO image!! Some pretty blinking colors but no image.
An effing nightmare, and an expensive one.
So the solution turned out to be:
NJ Haas just happened to have an oem 13 ft dfp cable for the GR510 lying around, and for a mere $120, they gave it to me. Had they not had it, it proly would have been weeks to get it from CA Haas.
We took off one connector on each end (the original and the newly-bought cable), and spliced the two cables together. No mean feat, let me tell you. And not a special cable, either. 13 pairs of 28 ga wire, nothing apparently special, I don't know if the wires were even twisted pairs. The whole bunch shielded.
Splicing dat cable was *a muthafucka*, took two of us HOURS to do the job, with multiple soldering irons, vises all over the place, continuity testing
*up the ass*.... very time consuming, very niddly work, very easy to make any number of disastrous errors, pinout-wise.Hint to the brave: don't even *think* about a splicing job like this without a fine low-watt soldering iron and **separate flux**. Flux-core solder is fine for some stuff, I spose, but separate flux makes all the difference in the world for fine stuff, allowing you to instantly tin the wires, which then makes joining MUCH easier and more reliable, AND shrink-tube friendly..
When all was done, the screen image was absolutely PERFECT. I swear to god, we could have spliced TEN cables end to end, with no image degradation!!
So I don't know what was up with these other goddamm cables, replacements, but had I known the difficulties in all this, I would have gone the Haas oem/splice route from the gitgo. A tremendous learning experience.
This pendant re-location cost me a goddamm fortune, when all was said and done, proly $1,000 *just to move a goddamm pendant 15 feet*!!!!! Jesus H. Christ.....
My advice to anyone else doing this is..... well, I don't know.... all these cables were a fuknBUST, and I don't know why, AND cable-splicing is no joke either, bleeve me, so the allure of just buying cables off the shelf strong indeed, BUT it can prove very costly.
But splicing seems to yield an almost *guar-own-teed* result, IF you splice
*working OEM* cables.If splicing, you MUST check the pinout of EVERY wire splice as you go along, to make sure there are no mistakes -- much easier said than done, as it's not mechanically easy to probe the contacts on some connectors, ESP dfp connectors. I had to use a #75 drill on the probe to "get in there". And two people make the job much easier, both the pinouts and soldering itself.
You then have to "protect" yer completed cable splice, also much easier said than done. We had to cut and modify a 2x4 electrical "handybox" and modify romex connectors to ensure the ground AND strain-relieve the splice itself. What a fuknPita.
But the result was perfect, screen/image-wise, absolutely perfect, ZERO degradation. End of a nearly two-week very costly drama/nightmare. Just today's effort, which included picking up the Haas cable and other materials, was a whole day for two (very motivated) people.
Heh, now I know why Haas balked at relocating the pendant themselves.... LOL
