Ok, but do we know if MT routerboards are galvanic isolated? I don't think so. I've had several instances in the past where an occasional touch of a plus wire to the casing of and board housing cause sparks or the routerboard to be rebooted....galvanic isolation solves all problemsSeems you were not with cars for the time long enough to see the cars with positive pole on chassis. Anyway you are right. It is better to have all devices with the same grounding.
If device has it then does not matter whether grounded is + or -
oeps, my post just crossed yours...SXT ac does not have galvanic isolation and it supports only positive 48V. May be later we will add -48V support to some new products.
hmm, Is it not? I don't know, haven seen an ac unit yet in real. But ROS 6.17 should be 'ac'-compatible. 6.17 on any other radio has NV2. Does your post mean the NV2 options are not available? Or do they just not work? Or is it inherent to the 8702.11ac protocol that tdma is not supported?Is there anything in the works for an NV2 equivalent of 802.11ac?
As it is unnecessary in SXTSXT ac does not have galvanic isolation and it supports only positive 48V. May be later we will add -48V support to some new products.
"Unnecessary in SXT", because normally nobody connects these to ground... but what if someone now decides to follow manual and does connect it?As it is unnecessary in SXTSXT ac does not have galvanic isolation and it supports only positive 48V. May be later we will add -48V support to some new products.
-48V power supply is used only in bigger base point
Also, this functionality has been greatly appreciated by 2-3 products:
CRS with more SFP fiber to aggregation NETMETALs fibers
in NETMETALs
maybe in QRTac

I am just anxious to know how the situation is. I was planning on buying some ac kit to deploy a new tower for a set of new clients. But if tdma is not working or available I am afraid that ac, even with its standard build in interference avoidances, still will suffer in a matter of years by all the other towers that probably are going to be converted into ac in the times to come...
I hated it to have to replace my units every so many years, so I'd rather wait until a product line is a bit more matured before I start to deploy.
Meaning at the same time I am walking behind the competition that asap push the new line of ubnt products in every corner of the country.
So yes, MT; tdma on ac? When? How? Or, why not?
oeps, my post just crossed yours...SXT ac does not have galvanic isolation and it supports only positive 48V. May be later we will add -48V support to some new products.
But anyway, shouldn't it be mentioned now that these units can't be used in earthed situations together with -12 or -24V situations. Or ru just happy the unaware user is burning his stuff and has to buy new?
Thank you for information.R11E5HacD is 2x2 https://ispforum.cz/download/file.php?id=3611
Because I believe that he's flicking a R11E ac to RB912UAG-2HPnD-OUT, the information will be very concerned about.Really good news!
r11eac is seems based on AR9882 2*2, what about AR9880 and 3*3? I saw replies on other forums that compex ar9880 3*3 solution don't work yet with mikrotik. And it is damn expensive
Would this card (r11eac) work with 912-series (external mini-pcie), not only with rb800/900 board?

BTW (about t-shirts)- mikrotik logo with "routing the world' is more recognizable and certanly needed
Thank you, Normis. I've already seen you fixed the description.License level is 4 and Netbox doesn't have USB
You need to be careful when purchasing miniPCIe ac cards, some of them are wider than normal, which means they don't fit in RouterBOARD products.You say these products are now available, where can I purchase them? I need to upgrade some backhauls ASAP. Also, there's a new Mini-PCI card, 802.11ac, high-power, that I can fit into a rb800. Any ETA on that? I bought a couple on ebay, 3 chain with MMCX connectors, but the card is so big it won't fit because of pins and the clamp bar that holds the cooling fan.
https://www.interprojekt.com.pl/advance ... 25_07_2014AC products starting to appear on Bulgarian distributors. Still they are 'coming soon' but getting closer now with expected dates to be available.
Yup I saw it ) Thanks for this!SXT ac supports real 802.3af/at standard.Maybe this will make us closer to 802.3af, 802.3at common support?
Yes, I was able to get one model to work, but the bigger one that is wider, with the much better MMCX ports is too wide. Dang!! Question, why the heck are you guys making the R11E-AC card a Mini-PCIe, instead of all the standard PCI cards? Does it support faster speeds on PCI or something?You need to be careful when purchasing miniPCIe ac cards, some of them are wider than normal, which means they don't fit in RouterBOARD products.You say these products are now available, where can I purchase them?

The SXT ac and Netbox ac products are on their way to distributors worldwide, many of them should have received them already.
I think its made by kam-fab. ODE-MTK. Nice metal enclosure white box with a hinged door that swings open.I hate those other boxes with 10 screws you have to take out everytime.@wispwest; What outdoor housing do you use for these rb800's? I'd like to use them more too, but due their size I have to buy a complete cabinet just to house these. The rb4xx extended board series has plenty of outdoor boxes available. But just too small for rb800...
(mini)PCI-E is the industry standard these days. (mini)-PCI es getting extinct. Current wifi chips do NOT support PCI, only PCI-E.Question, why the heck are you guys making the R11E-AC card a Mini-PCIe, instead of all the standard PCI cards? Does it support faster speeds on PCI or something?
No, it will work at Gigabit in any case. The above text means that it supports both A and B modes, but when using B mode, you need a crossover cable.From SXTac Datasheet: "802.3af/at supported (Mode B. requires crossover cable)" ... Does this mean that it will only link at 100Mbit when using 802.3af/at? Because Wikipedia says that "Mode B delivers power on the spare pairs".
But there are no spare pairs when using Gigabit
I expect the new chipsets to have more CPU/Memory power to help handling the nv2 overhead.I've beta tested AC products already for 'another' manufacture and y'all need to also realize that you can also get more throughput using same 20/40 channel widths with AC compared to N. Its not a whole lot, but 10-20%. Where this would benefit is bands where we use smaller channels, like 900 and 2.4 10mhz channel's.
My Distributor in Germany has received a batch of SXT AC so I will start testing next week.A comment from one of the biggest distributers in the US:
"Where the new Mikrotik items are concerned, this equipment has yet to be released for distribution and pricing even remains unclear, so I will follow up on that part of your inquiry as soon as more information becomes available. Several customers have expressed an interest, so I hope to have more of an answer sooner vs. later, of course."
Will there be an U-5HnD equivalent or perhaps a SoHo model coming out soon? I don't want to buy a few U-5HnD units and an 802.11ac model comes out soon after.others coming soon

It could take a while until everyone receives their shipments. SXT ac was shipped first, this is what I meant. Netbox is still not at the distributors.They all said they contacted MIkrotik and it will be 8 WEEKS before the Netbox5's will start shipping, that's 2 months, great. I need upgrade some PtP's now. Only thing that's available is the SXT-AC's, which is the only item anyone has been able to get hands on.
no, it does not, negative is the ground.does the 953GS-5HnT have galvanic isolation? can it function with both positive and negative voltages?
Waiting for the boards with .af powering.New AC products:
RB911G-5HPacD - http://forum.mikrotik.com/download/file ... w&id=17848
RB922UAGS-5HPacD -
No more waiting required. We have the NetBox5 in stock now as well as all the other new Mikrotik 802.11ac products.They all said they contacted MIkrotik and it will be 8 WEEKS before the Netbox5's will start shipping, that's 2 months, great.

Is there any SXT shield kit available?Got my first batch of SXT AC and SXT AC SA.
802.11af works fine. The non SA Version does not have a shield painting inside.
So for ptp on a loaded tower some additional shielding might be neccesary.
