I meant opening the cable cover to expose 6 wires.
Assuming the six wires are color-coded same as my cables, just switch,
Pin3 orange-to-yellow
Pin4 yellow-to-orange
without disrupting the other four wires.
I updated the original post to reflect this elaboration.
Please bear with me here as I’m a software guy and I’m prohibited from possessing a screwdriver in twenty-four states. So is this right?–
Slice open enough of the cover to remove or scrunch back the shielding to expose the wires and to perform the following steps;
Assuming, as you said, orange and yellow, cut those two, strip the ends, twist the swapped ends together, solder, and insulate each one with electrical tape (lazy man’s heat-shrink tubing);
The other uncut wires are now a bit longer than the spliced ones; kink and fold them if necessary, then use electrical tape to wrap the bundle.
Test 3-to-4 and 4-to-3 continuity.
Optional wire color test: after cutting the first wire, do an end-to-end continuity test on pins 3 and 4 to make sure one of those is now open; if neither is open, either throw the cable away or splice the two cut wires and choose another one to cut and test. If one is open, cut the other wire and test continuity on the other pin, etc.
Yes. After you have successfully made one DIY CS44A cable then the second cable is easier because you already know the color coding of the wires for pins 3 and 4.
Just found this third method mentioned along with the cutting and opening methods:
Cut the extension cable, prepare the ends and crimp them to RJ45 connector with cross connecting leads from pin 3 on one end to pin 4 on other and vice versa. Use RJ45 to connect them back together. This method is the easiest if you know how to use RJ45 and have the crimping tools and connectors available (not mentioned in material list).

Hmmmmm, connecting PS2 cables with RJ45 connectors? :rolleyes:
In the link you provided the author speaks about using modular connectors. But he/she never did actually use modular connectors. Both the pictures and description shows the wires being soldered together. So he/she was speaking about an alternative method if you like using modular connectors.
But let’s poke at this a bit. You would start with the female PS2 cable end and attach a male modular connector. Then attach a male modular connector to the male end of the PS2 cable. And then what? Plug the two modular connectors together with a coupler? Something like this?
Sorry, picture got lost.
I challenge you to show us a finished/tested-working cable using modular connectors!
As I understand it, he meant simply another way to do basically what you did: cut the serial cable and splice it back together again, swapping two wires before splicing; but he’s using the modular connectors to do the splice via (I assume) a coupler, instead of soldering. The ends of the cable wouldn’t be involved in the modification.
Whether it’d be easier than soldering is an open question, depending on how difficult it’d be to get the four wires into the each RJ45 connector properly before crimping.
If I do it that way and get it working I’ll be happy to post a pic! (I won’t be starting this project for at least a week or two, but all the gear is ordered.)
Thanks for this clear tutorial, got mine working fine but one of two ‘equal’ cables did not have the correct number of wires so I had to cut open the connector to fix this (I wasn’t in the mood to buy and wait for new, possibly correct cable).
I notice that I haven’t followed through with posting a pic. If anybody’s really hot to see a cable with a couple of RJ45 connectors in the middle plugged into a coupler, let me know. I tested the cables with a VOM, but am not actually using them because, as noted in another thread, immediately after making them I discovered that my current-model Phonaks require CS44 cables, not CS44a.
Yes I’m curious to see a picture of your variant CS44a cables. Read further down in this thread for discussion about whether to use CS44 or CS44a cables for Phonak Venture sereies…
OK, but it’ll have to wait a while – the cables are at home and I’m on an extended trip.
I have just created the Adapters for to create from a standard CS44 one Phonak CS44a cable
And I succeeded and can definitely say that my Phonaks Ventures still use CS44a.
Exactly the way Phonak suggest it inside Target help cable guide.
So may you American folks got some special Phonak series.
Yikes!! That means either you or brec has some wires crossed.
I verified that the Target 4.1 Help Cable Guide does indeed specify CS44 (Phonak Version) 058-0255 cables (meaning CS44a). The same cables are listed for both AudeoQ/Quest and AudeoV/Venture.
Hmmmmm; I’m wondering if brec’s cables that he thinks are CS44 cables are actually CS44a cables…
CS44 cable + DIY adapter would work for Phonak.
CS44a cable + DIY adapter would NOT work for Phonak.
I suppose it’s possible. The eBay listing said “CS44”.
I’m still on an extended trip, and while I have the cables with me, I don’t have a VOM else I could test them pretty quick. Or maybe not: the HA end of the cable is very tiny.
I have in the mean time verify my cables with one other older set of Phonaks with Spice series and connected to them successfully.
So I can say Spice and Venture uses the same Programming Cables !
Here 'tis:
I like em!
Does the Hi-pro box do anything or is it just an adaptor from USB to what looks like old style keyboard plugs?
If the Hi-pro is required where do yet get one and how much?
I applied $5.12 to an eBay vendor in China for a pair of the PS2 cables. That princely sum included shipping which took seventeen days to here in New York.
The construction of these adapter cables allowed me to save $45 or so and use my Phonak CS44a cables to program for Oticon which uses CS44 cables.
I felt it was a good way to use tech skills to save money.
Good work!!
Oh, you should share your source for the PS2 Mini-DIN cables as links to a source with six wires tend to be hard to find.
