PTA Posted January 25, 2013 Report Share Posted January 25, 2013 Hey Palmer, To be clear, what is actually happening when you use the timecode delay on the ERX2? Does it speed up the timecode being received by a certain value? So -1 frame means it's adding 1 frame to the timecode at the receiver side? thank you, Andy For example, if you set the TC offset to -1, if you received a timecode of 00:01:19:28 at the ERX it would compensate it to output 00:01:19:27 instead, therefore making up for the delay as if there was no delay.

andstrumental Posted January 25, 2013 Author Report Share Posted January 25, 2013 That didn't make sense to me until your last post. Makes good sense now, thank you for the follow up. Andy Quote Link to comment Share on other sites More sharing options...
Boomboom Posted January 26, 2013 Report Share Posted January 26, 2013 More problematic is that there's no TC Delay parameter to adjust in the TRX900 extended menu...using a QRX with generated TOD as TC sender via zaxnet to its corresponding TRX-STA as a cam hop for example. Maybe if we got an ERX we do all the adjustements (the -1.5 frame) then de-activate zaxnet in the TRX and jam it manually in the ERX (repeating mid-day) ? The TRX internal TC gen would do the job I guess... Quote Link to comment Share on other sites More sharing options...
efksound Posted January 26, 2013 Report Share Posted January 26, 2013 AFAIK This only compensates for the TC and audio stays untouched, to delay audio there is another option on the ERXTCD units Quote Link to comment Share on other sites More sharing options...
soundslikejustin Posted January 26, 2013 Report Share Posted January 26, 2013 AFAIK This only compensates for the TC and audio stays untouched, to delay audio there is another option on the ERXTCD units Correct, this does nothing to the audio, which by design comes with 20ms latency. You can delay it further, but not bring it forward... Quote Link to comment Share on other sites More sharing options...
Derek H Posted January 26, 2013 Report Share Posted January 26, 2013 If you ask me, we should not be the ones having to trouble shoot this. Quote Link to comment Share on other sites More sharing options...
PTA Posted January 26, 2013 Report Share Posted January 26, 2013 If you ask me, we should not be the ones having to trouble shoot this. Well, the user end noticed there was an issue and this is the current workaround. And Howy is currently trouble shooting it on their end. So we are all good for the time being.

Earmuffs Posted January 26, 2013 Report Share Posted January 26, 2013 Has anyone found it necessary to adjust the audio delay in addition to the TC delay? Can someone give an instance where audio delay would be most advantageous? I just picked up a set of these and haven't started to use them yet.

Earmuffs Posted January 27, 2013 Report Share Posted January 27, 2013 I haven't had to deal with that directly. Usually an ac tells the director it's due to the long video runs and its left at that but I do agree its necessary to please the important people and to keep in mind in the future as its something I can now do something about. Thanks! Quote Link to comment Share on other sites More sharing options...
efksound Posted January 28, 2013 Report Share Posted January 28, 2013 Something I didn't notice is that when you set a TC delay, when you switch on the unit you get this new line while booting TCDELAY=%2.1F FR I've tried to change the TC delay value to see if the value changes while booting but it always shows %2.1F Running 1.15 firmware Quote Link to comment Share on other sites More sharing options...
Michael Miramontes Posted January 31, 2013 Report Share Posted January 31, 2013 ....with a custom lemo/5pin xlr split cable I made. Would you mind sharing how you wired this up? Quote Link to comment Share on other sites More sharing options...

Boomboom Posted February 1, 2013 Report Share Posted February 1, 2013 Michael Go from your lemo to a first BNC for "TC in" then from that BNC to the second BNC for "TC out". Would give you something like that: Now for wiring the cable, colors as an example... Lemo Pin 1 ( gnd) -shield Pin 2 (TCin) -white Pin 5 (TCout) -black To: BNC1 (TC in/ ie to "get" TC from the recorder on connected unit) Center pin - from lemo pin5 -black Shell - from Lemo pin 1 - shield , then re- wire from there to BNC2 Tie and isolate remaining wire (white) to go "directly" to BNC2 BNC2 (TCout / ie to "feed" your recorder from connected unit) Incoming from BNC1: White to center pin ( that wire coming from the lemo ) Shield to the shell Quote Link to comment Share on other sites More sharing options...

dominiquegreffard Posted February 2, 2013 Report Share Posted February 2, 2013 To get frame accurate tc on camera is it still necessary to delay tc by -1.5 frames on software version 1.15 on erx? Quote Link to comment Share on other sites More sharing options...
Boomboom Posted February 2, 2013 Report Share Posted February 2, 2013 Yes Howy is looking into this. There still hasn't been any official announcement from zax about this so far (but it's just been a few days); I guess 'til we get that memo, we'll have to keep on setting our units to -1.5fps ... I hope the patch works as well for the scenario I indicated earlier too (TRX getting TC from QRX mounted on cam). Quote Link to comment Share on other sites More sharing options...
andstrumental Posted February 4, 2013 Author Report Share Posted February 4, 2013 Would you mind sharing how you wired this up? tip to pin 2 on the lemo ring to pin 2 on the 5Pin XLR Sleeve had ground from Pin 1 on the Lemo and Pin 1 on the 5Pin XLR Make sure your ERX is outputing the timecode to tip Quote Link to comment Share on other sites More sharing options...

efksound Posted June 25, 2013 Report Share Posted June 25, 2013 Can't find the post right now but as far as I remember the final word on this was that the delay with the TC was only on the UHF transmission side and NOT on the Zaxnet (IFB) side Quote Link to comment Share on other sites More sharing options...
howy Posted June 25, 2013 Report Share Posted June 25, 2013 The 1.5 frame delay bug was fixed in the TRX software starting at v8.12. I would make sure the rest of the equipment that touches the timecode is up to date as well. -howy Quote Link to comment Share on other sites More sharing options...

André Boisvert Posted September 9, 2013 Report Share Posted September 9, 2013 Speaking of Nomad to ERX delay, is the difference I'm seeing here (anywhere from 1 to 6 frames), the result of a display lag in the ERX's LCD screen? Nomad 5.23 ERX 1.21 Quote Link to comment Share on other sites More sharing options...
