vale Posted July 19, 2013 Report Share Posted July 19, 2013 I've just ordered a second QRX (I already own one with IFB Option), but I wasn't able to get infos from my seller about the usb cable to link the receivers in order to use the one with the ifb transmitter for them both. Actually, I also asked Zaxcom (no detailed info on the user guide too) but it seems they don't provide that cable. So, is there someone here that use this configuration and would tell me which is the cable and connector parts required for the matter? Thanks, v.

Ryan Coomer Posted July 19, 2013 Report Share Posted July 19, 2013 This is from the QRX manual dated April 2013 and shows the wiring. It should be standard USB 'A' connectors. qrxlinking.pdf Quote Link to comment Share on other sites More sharing options...
soundslikejustin Posted July 19, 2013 Report Share Posted July 19, 2013 Buy a male to male cable (or, if you're like me you've got a few spares lying around....), chop down to size, rejoin in the middle with the wiring as defined in the attachment above.

vale Posted July 20, 2013 Author Report Share Posted July 20, 2013 Thanks all. When I read this on the last QRX manual I thought some special cable was involved, not only a different wiring. So, basically, can I use a common cable, just rewired correctly, right? thanks, again. v. Quote Link to comment Share on other sites More sharing options...

So, basically, can I use a common cable, just rewired correctly, right? thanks, again. v. Right. The wording of that sentence is poor. The connectors are 'generic' USB connectors, they are just wired differently. A 'generic' USB is wired: 1-1 2-2 3-3 4-4. The Zaxcom serial connection is wired: OUT to IN 1-NC 2-1 3-4 4-NC Quote Link to comment Share on other sites More sharing options...
Wandering Ear Posted July 20, 2013 Report Share Posted July 20, 2013 The warning about them not being USB connectors is very misleading. It should state that this is not a USB BUS, it is a RS422/RS485 BUS on standard USB connectors. If you have problems making the cable, I'd be happy to make you some. PM me if you want.

Wandering Ear Posted July 21, 2013 Report Share Posted July 21, 2013 Wandering Ear made some for me. Hey Jan, Thanks for the recommend by the way. Are you using the cables? How do you like controlling the transmitters through the QRX? I've done it in testing, but haven't tried it in the field. Quote Link to comment Share on other sites More sharing options...
GAGaudio Posted September 11, 2014 Report Share Posted September 11, 2014 Hey Jan, Thanks for the recommend by the way. Are you using the cables? How do you like controlling the transmitters through the QRX? I've done it in testing, but haven't tried it in the field. Are you still making these usb cables?

RadoStefanov Posted September 12, 2014 Report Share Posted September 12, 2014 Easiest way is cut 1 usb cable, solder it proper and heat shrink the hell out of it. Takes 2-3 minutes. Quote Link to comment Share on other sites More sharing options...
Wandering Ear Posted September 12, 2014 Report Share Posted September 12, 2014 It's a lot cleaner to make the cables instead of patching two cables together in the middle. The USB cables are not difficult to make if you have the parts. Quote Link to comment Share on other sites More sharing options...
RadoStefanov Posted September 13, 2014 Report Share Posted September 13, 2014 Agreed. But if you need a cable in a hurry you can always just snap an USB cable in half... Quote Link to comment Share on other sites More sharing options...
Michael Miramontes Posted January 23, 2015 Report Share Posted January 23, 2015 Back on this topic please. I'm in the process of trying to make a cable to connect my Nomad to RX-12. Can I use this same method for the cable? I'm working in a small town so I only have access to Walmart. The only USB cable they sell is a printer cable. I wonder if I can buy two of those and splice them?? Quote Link to comment Share on other sites More sharing options...

I'm not sure that the serial connection between Nomad and RX-12 is the same as between the QRX's, but yes, buying two cables and splicing them in the required connection will work fine.
