DM-MD16X16 Specs
|
I have a client with a DM-MD16x16 from 2009. ?The product was made end of life in 2019 with the replacement CPU3. ?Over the 10 year period (2009-2019), were there any substantive changes to the DM-MD16x16 other than the cards being updated to 4kz. ?Specifically, did the hardware of the switcher change over the 10 years? ? ?I know the older models used multi gang output cards. ?Any other changes? ?

¿ªÔÆÌåÓýThe ganged cards was more of an aesthetic change than anything else ¨C the chassis didn¡¯t change in any substantive way and you can use single cards in an original switcher more or less just as easily as you can use the ganged cards in a brand new switcher. ? Even with the CPU3 card nothing really changed except the card in the CPU slot ¨C you can order a CPU3 card for your original switcher if you want. Same thing with back and forwards compatibility of the 4KZ cards ¨C in many ways the DM architecture is one of the best examples of a long-lived, serviceable, and incrementally upgradable tech product in the AV world. ? At some point (~2015/16, IIRC) the power supplies (number, configuration, and internal orientation) got changed and there are relatively minor differences as far as airflow go (the ¡°original¡± design, at least for the 16x16 uses perforated side panels while the ¡°new¡± design has punched fan openings with circular metal grilles added after the fact. (Learned this partially because the 30A 12V PSU in my first DM-MD16X16 failed and it wound up being significantly cheaper to just buy a new-to-me 16x16 via secondary sources than order the replacement from the PSU OEM) ?

I had a case where the older cards would not fit properly in the newer DM-MX16x16-CPU3 chassis.? More of a physical mounting issue with the plates on the older cards are larger then the cutouts in the newer chassis.? Not a serious issue and was easily corrected by splitting the cards up and? installing the new type plates on the cards.
Other than that, I haven't noticed any issues.? But to be honest, I haven't tried the new 4KZ cards in an older chassis.? Whether the back plane in the old DM chassis has enough bandwidth would be a question you should ask Crestron. |

Steve,
You bring up a good point. ?All the output cards are the multi gang fiber cards - DMCO-1111 (discontinued). ?I could split them up but I'd need to find new face plates. ?The other option is to upgrade to DMC SO HD but then I'd also need to upgrade all the RMC. ?I could just use one of the multi mode fiber connectors. ?The problem with upgrading all the way to 4kz is some of the locations only have fiber to the RMC. ?I don't believe I can go from a 4kz output at the DM MX 16x16 to fiber and back to CAT6 for the RMC 4kz. ?

Crestron has, in the past, offered a free "upgrade" faceplate kit for the output cards. On Mon, Mar 1, 2021 at 2:04 PM Bob Baxter via <bobbaxter1=[email protected]> wrote: Steve, |
¿ªÔÆÌåÓýThe 4KZ don?t consume more bandwidth than the 4K-cards, maximum 9Gb/s. Everything above is compressed to that rate. ? Cheers, Thorsten ?

Last month we updated an old 8X8 from around 2011 with fiber output cards to full 4KZ cards. Although I didn't need them in my situation, you can get free plate adapters to fit the new style cards. You have to run thru the online DM upgrade tool and it will spec the parts needed. No issues with any video bandwidth or anything video-wise. Firmware was very old so I did it in multiple steps as advised by TB:
2.35 > 2.37.02 > 2.41 > 2.45 > 2.48.01 > 2.50 > 2.55 > 2.59 > 2.61 > 3.03.05 Firmware was the hardest part as it took a couple hours.? |
