I could swear that Jeff B just did an article in CePro about HDMI extenders and why the termination scheme matters. It wasnt so much about A or B and I believe its why Ethereal uses there own standard.

Anybody used this Matrix and have opinions outside of whats going on with Gman?
I got a little promo offer that makes me really want to give it a shot and a Control4 upgrade that it fits perfectly into. After some in shop testing, we installed our first unit in a clients home about a week ago. The system included 2 directv boxes and a panasonic bluray. Possible plan for AppleTV. One TV( 2 year old samsung DLP) had an AVR and the other(new Panasonic plasma) was standalone. Planning on adding the other 2 TV's when exercise room is finished. Plug and play out of the box with no issues. Didn't use the EDID learner as things were working ok. Runs were about 75' cat5e and terminated in 568A. Terminated to 48 port wall rack at head end with patch to matrix, TV end had RJ45 crimp on directly to rcvr with no keystone.

Thanks guys. I'll wait for some real world time proven feedback and even though Zektors 8x8 is going to be overkill for the little project (4 source x 4 zone) that I have in mind I think I'm going to use it. Maybe Ill add some sources.

General Info; We were testing a number of Redmere equipped HDMI cables this weekand were having a number of issues on Samsung and Olivia (yeah I know, but we like a lot of test subjects). Turns out that Stewart had connected to HDMI 3 on these sets, when he changed to HDMI 2 almost all issues went away (BTW; the Sony did not have these problems). I have said it before ALWAYS use input 2, it is the most direct line between input and processor.

Direct Pairs maintain the balanced mode AND have fewer timing errors. AND is just simpler to do.

Budget...got in the way! :( I always find that when the customer's budget gets in the way, it ends up costing ME more money. The cheaper I try to design a system, the more money the company ends up loosing. I refuse to use anything other than Crestron DM to switch video. The new 6x6 should be affordable for most Crestron customers that need video switching. If not, they need local systems.

I try to steer clients away from distributed HDMI. Unfortunatley this job was a takover so we were stuck with what was there.....

+1. I don't know of any manufacturer that doesn't say DON'T USE EZ-45's. Not to start a peeing contest, but I deal with lots of manufacturers also and have never had one mention EZRJ45's in a negative light [or at all for that matter]. If anyone has some *technical* information they can relay on this subject I'm all ears...I'm always eager to know if there's a better way of doing things. So far, a very credible source on all things cable has suggested the EZ's as the best approach for data terminations and I've never had a problem with them. I will say this about the crimp tool: If you do not push the connector fully and firmly into the die when crimping and [simultaneously] trimming the excess, you get a less-than-favorable result.

The main difference between me and most of the people in this industry (my technicians, and possibly you as well)...You guys tend to be natural tinkerers, you're the kids who were taking their moms toaster apart to see how it works, you have a natural curiousity. I on the other hand don't, I don't care how it works, I don't want to know. It's none of my business. My job is to make it work. I make it work by reading the instructions. If the instructions tell me Not to do it, I'm not doing it. ); background-attachment: initial; background-origin: initial; background-clip: initial; color: rgb(204, 0, 0); background-position: 0% 50%; background-repeat: no-repeat no-repeat; ">Important Notice: To reduce video dropout problems from ceiling fans and other EMI issues, it is strongly recommended that you pull shielded CAT5e/CAT6 and use shielded RJ45 connectors with this extender product. "EZ end" connectors are not recommended for use with HDMI extenders. Technicians on the other hand want to know why the directions/instructions would say that.

The reason we (Ethereal) do not recomend Pull Thru style terminals is because the process of cutting the wires while compressing the contact blades into the wire pulls on the conductors which in turn thins the wire reducing data banswidth. While this may be accepable for 10/100 networks it is not fot HDMI. That aside almost all of the failed jobs done with Pull Thru RJ 45's work when reterminated with conventional style terminals. There often an issue with the cleanlyness of the wire cutting leaving stubs hanging out of the RJ45, this is bad JuJu.

I will say this about the crimp tool: If you do not push the connector fully and firmly into the die when crimping and [simultaneously] trimming the excess, you get a less-than-favorable result. No peeing match but I can probably find 10 different manufactures that will tell you not to use EZ RJs. Whether those connectors are fine or not I haven't seen concrete proof either way. I did see arc burn marks on a connector that was passing 12v before. That was 7yrs ago with a Vaddio Eagle Eye Polycom camera extender and it was the last time I used the EZs. It was my install and Vaddio even sent their chief engineer down to look at the install since it appeared their piece wasn't working right.

Who says you can't put 61" plasmas up on cantilever mounts using toggle bolts? <---Thanks Ernie ;) |
