There are differences mainly because of the number of TS and TRS.

I went thru a nightmare identifying a bunch of cables I received with a large Alesis auction/purchase  (music store went BK)

The packages were labeled DM6 but had (9) cables..6 TS,3 TRS and as it turned they were actually for DM8's.
(I had re-sold them as DM6 as they were labeled as such)

It took me some time to figure it  by using Alesis comparison chart and the New England Music Supply site as they had connection/wiring diagrams..

http://www.alesis.com/drumscompare

DM6..(7) cables (6 TS, 1 TRS) http://www.newenglandmusicsupply.com/drum-modules/alesis-drum-modules/alesis-dm6-drum-module/prod_178.html

there is some confusion on the expansion harness..

DM6 "expansion" (9) cables (8 TS,1 TRS) or (7 TS,2 TRS?)
the Alesis pic shows 2 TRS?( http://www.alesis.com/print/print.php/229047)

the diagram on the New England site shows only 1TRS ..snare and states it as a direct replacement part (not expansion)
http://www.newenglandmusicsupply.com/replacement-parts/alesis-dm6-cable-snake/prod_215.html

DM8...(9) cables (6 TS,3 TRS)

There is also a thread where someone had worked on a pinout

I thought I had seen before where you had purchased a spare harness for a DM8 from a member here. Need another? ;D

Do you have a pinout for the DM8? I would sure love to add that to the site. ;)

Hi Hellfire !!  ;D

I purposely kept one harness for the best interest of DM8 owners and selling it on ebay it for a couple bucks makes no sense as I had seen a lot of interest here for the pinout and could put it to better use.

I don't think the manufacturers took into consideration of what is the consumer going to do if/when these harnesses go bad, road-wear or get lost.then again as in my industry (Harley Davidson aftermarket for 30 years) it may have been calculated into the "end of life" of the product and they figure eventually you'd have to go out and/or purchase another product/upgrade.

It seems the harnesses have become like "hens teeth"as far as replacements go.

I plan on milling the top and bottom down to expose it like a cross section leaving the cables attached and then photograph/diagram.
I just have to make time to do the tooling to hold it which can also be used to machine a housing (possibly a 2 piece so then it would be possible to just add cables,the 25 pin connector and clamp together)

I have also taken some measurements and once I have an idea of the interior I may run it thru my 3D printer.

The DM6 expansion cable got my attention as it seemed possible you can add triggers,but being unfamiliar with the DM6 module I wondered how you would access these,then I noticed the diagram for the expansion cable showed the Hi-Hat and Hi-Hat control were now in the harness but the standard DM6 (7) cable diagram didn't show either one? yet there are (9) indicated on the face of the module.So the original DM6 with the standard harness didn't have Hi-Hat capabilities?
It could also be the New England diagram for the original harness is wrong and had Hi-Hat capabilities and later you added 2?

why is it then considered an "expansion" cable? It should have come with (9) with the original purchase.

It'd be like buying a car with a V8 and told you got it at the 6 cylinder price and later you'd have to buy a whole new harness to get the other 2 cylinders

Its all a bit confusing..lol  ::)

If you have access to a multimeter / continuity tester, it might be easier (and certainly less destructive) to just tone out the pins to the cable ends with that as opposed to dremeling the connector apart. Once the pinout is determined, it should be easy enough to make your own custom harness with regular TS/TRS cables.

Dremel?.. :o
I was going to mill it on a CNC to peer into it and see exactly how it was wired up.I guess I should have explained that I had already put a meter to it and matched the pins to the Tips and Rings but all the sleeves showed open no matter which of the remaining pins I tested so I am assuming (hate that word) they are all tied together for shield/ground? ::) or am I doing something wrong as I don't test this type of connector very often if at all.

thanks chase, we never quite worked out the logistics on the other harness so yea i still need one! i found a good deal on a backup module but i would like to have a backup harness to go with it.

Ah, so you have the _good_ toys. I want a CNC machine. :(

This is a DB-25 connector, right? What (if anything) does the metal shell around the pins connect to? That's typically grounded, so it would make sense that all the sleeves were grounded to that.

@pdaddy21

Since you already have a harness could you check/confirm the color codes,this way for future reference for members we have more than one person in agreement if someone needs to identify a cable.I also posted measurements for the cable length only not the molded plug end in case someone is going to build their own and use straights or larger 90's this will get them within range for original module placement.Then I will see if I can post a decent pic showing the cable ends and connector. ;D


with harness plugged in

top row (5):BLUE-HH control-TS(55")..WHITE-HiHat-TS(38")..YELLOW-snare-TRS(46")..RED-crash-TRS(59")..GREEN-ride-TRS(85")

bottom row (4):ORANGE-tom1-TS(55")..PURPLE-tom2-TS(64")..BLACK-tom3-TS(91")..GRAY-kick-TS(74")

I see a harness on ebay and seller claims it's for DM6,tested/works on DM8,has a  photo I have seen before of a DM8 harness from off the web.Other than the connector I dont see how it's possible with cable lengths matching up and the TS/TRS count,
and I also took a look at the DM6 pinout posted above and it makes no sense at all.seems rings/sleeves were crossed up.

according to someone who purchased the DM6 cable for his DM8..it wasn't compatible
