Serial and Parallel cables work-around?

Post by Immanuel »

I am not talking about hard drives here. This is about serial sub9 and Parallel sub25 cables.

I got my Alesis BRC delivered today. It is absolutely beautiful. Never before have I seen such a well kept 14 years old second hand 'instrument' before. But there was no cable included.

The Alesis BRC and the Creamware Sync cards use sub9 cables. For some reason Alesis chose to use male sub9 connectors, where standard serial cables for a PC used sub9 female connectors.

I was in 5 shops today, and noone had serial cables. One shop could offer me a parallel (male <-> male) cable and two female sub25 <-> male sub9 thingies.

Will this go as a substitute sub9 (male <-> male) cable? I think, that both serial and parallel cables where twisted pair as standard, and then it should be ok - or what? I really do not want to hurt my hardware.

what kinda cable do you need, then? db9 female to db9 male? this would be just an ordinary serial extender cable like

(use cookies)

if you just got the wrong type (male-male or female-female) you could look for a gender changer.

all based on the assumption that adat sync cables use 1:1 wiring, of course. if not, hm... dunno...

Really don't know what wiring convention is used, but I managed to find this on a quick Google search, hopefully it should give you some clues:

I am going to order a Hosa cable after Easter. Right now I use a 50 feet (maximum allowed according to Alesis specs - and the only parallel/serial cable I could find in 5 stores in town) parallel cable with a 25->9 pin connector thing in each end.

It appears to work ... or maybe not.

I have different issues comming up. One of them being, that when I 'Locate 0', the counter goes to 0, but when I then start again, it continues from the last stop point. This in itself makes the whole set-up useless. I hope a better cable will fix it, but I am sceptical. Then comes the question:

If it is not the cable: Is it a CW bug, or did I buy a beautiful but malfunctioning BRC? Has anybody else got the Alesis BRC up and running with VDAT?

excellent hint, Dark :)
possibly the problems people had with Adat sync while controlling a VDAT with a BRC were based on poorly shielded cables (?)
obviously this is not the 'classical' serial type (as the connector suggests), which doesn't even have twisted pairs, but just straight lines within one common shield for the whole bundle.
with the wiring scheme you should be able to build one from video cable, as that has individual shielding of the lines.

cheers, Tom

yeah, or that one. I seem to have misunderstood the mal/female problem. not the connectors on the brc itself are male, but the required cable... forget about the gender changer ( or use 2 of them :) )
