Hello.
in the data sheet, say that 433uah have a monitor voltage.
but… where in the routeros can i check that?
inside system health, exist the information about the fan mode(auto-manual); use fan(main-auxiliary) Active fan (no information); voltage, but it’s the monitor voltage =S ? say 22.2v
/system health print
or if you want a script answer, try http://wiki.mikrotik.com/wiki/Monitor_input_voltage_on_RB333/433AH
thx for your answer, its very usefull.
but i have some questions @_@
inside the scrip say that:
Maximum = 14.2v at 13:00:00 aug/28/2008
Minimum = 12.5v at 05:00:00 aug/29/2008
in my RB 433UAH is 22.2 to 22.4
i have a power of 24v
its a lot?
inside the datasheet say:
Power over Ethernet: 10..28V DC (except power over
datalines). Power jack: 10..28V DC.
hmmm… i understand that minimium is 10v and max 28v.
i think change the power up 28v.
its necessary? or not? why?
Thx for all!!! 
If your board is fully functional, why change the power supply?
The RB433’s in my experience should be run at a higher voltage, this is because what you really need is watts into the device, as watts are a factor of volts multiplied by amps, a 12v 1a power supply is half the power of a 24v 1a power supply. My current RB433AH is being run on an old laptop power supply giving a DC of 18v 4.9a. Also you get voltage drop when you start running the cables. I brought a 24v 2a poe injector and the voltage drop was so significant that 24v became around 18v (24v x 2a = 48w, 18v x 2a = 36w) and I kept getting power problems. Ran the system overnight and the POE was dead by the morning.
But if your not having power problems why change the power supply?
Josh.
Thx!!! for your complete answer.
really i have problem with the power transmition, i have 15dbi omni, with cable lmr400 and Cable MMCX-N, but the max distance are 200mts, in the client show reciving 17dbi (in her computer), its so slow, i have a MiniPCI Valemount KXS30SG. I put in Tx Power card rates 29. Band 2.4Ghz-BAntenna Gain 15 - Country Peru - Frequency Mode Manual txpower. Preamble Mode both (long & short). Data Rate Default - Adaptive Nouse Immunity ap and client mode. But i dont now what to do and what to thing… the max distance is 200mts, 400mts dont exist signal @_@
i speak spanish, sorry for my english. I hope that you can understand me.
I use that Valemount radio as well. I’m assuming here that the radio is plugged in via the MMCX cable (the big one). For some reason the ports are mislabeled. In winbox try switching (under the wireless page on the radio) the antenna mode to antenna b.
Josh
well i cathed =P, then you think, the problem could be the conector (MMCX to N) the little to big.
this is my conection.
[ MMCX to N-female] + [lmr400 willson N-male to N-male] + [N-female, omni 15dbi]
using “antenna b” i will use other port in the Valemount =S ? i need change the plug??
what is the correect instalation with the valemount radio?
kind of conector, tipe of cable, etc…
do you have the same system like me?
RB 433uah (poe+power 24v) + valemount + 15dbi omni?
thx for you answer. 
Yes I have several very similar setups, though I do not use the UAH, just 433 with or without AH.
The problem with the valemount radios is this, they have 2 connectors, MMCX and ufl. On the physical card you will see that printed on the board by the MMCX is the word ‘main’ and by the ufl ‘aux’. This is WRONG. Using MT, antenna A is linked to the ufl connector, antenna b is linked to the mmcx connector.
antenna mode = antenna a = ufl connector.
antenna mode = antenna b = mmcx connector.
Josh.
i will check and post the result tomorrow in the morning (here 12:30am Zzz…)
thnx very much for your help.
well, i think that its better main (conector mmcx) that aux (ufl).
im right?
Yes, the MMCX connecter is better.
Omni with nfemale → n-male to n-male → n-female pigtail to MMCX → MMCX connector on radio → Winbox antenna mode → B.
This will give you the best results. Hope that really helps.
Josh
I used those numbers in the example because they were from a real setup using a 12v deep cycle battery and a solar panel. You are good at 22v. I hope you find my script as useful as I do!
well, i changed the mode a to b, inside anntena mode. i dont have conetion yet, the real out power (Transmition power)is low. the signal disapear over 300mts. i dont know what to do. i put the power directly in the jack power (no use POE).
the monitor voltage show now 23.3 V
what do you think?
my omni 15dbi its OK with the cables.
i have a AP TP-LINK that establish conection max 500mts. but when i connect the RB, over 300ms the signal disapear.
what do you think?
really, i dont know. i will call to the store where i buy the MK-valemount, all the equip. may be that the valemount have a problem?
Is the antenna an a-mode (5.8GHz) or b-mode (2.4GHz)? If you are just changing modes, the output power will suffer when the antenna is fed the wrong frequency.
ADD: Appears your problem is not power related.
well, in the datasheet the valemount (KXS30SG) isnt 5.8Ghz. but i trie in mode a and mode b, and the result are the same, im thinking that the card have problem. i will notice to the vendor (here official reseller is COMUTEL).
what do you think? What’s the problem?
im sooo confuse, its my first equip MK, and i have a lot problemas >_>
@_@
You may be correct about the wireless card. I don’t know what that specific card will do if you select the incorrect frequency range. I use the R52 cards for a-mode. They have all performed well for over a year.
.
well i checked the ports in my card, and the main (MMCX), aux (UFL). Mode a or b the signal is too weak.
could be thath my card its wrong or broken?
hi guys, i need some information about my MiniPCI Card, how can i see the model exact, chipset, etc.
i bought a MiniPCI Card: Valemount, model: KXS30SG
in the datasheet say:
Atheros AR5414 6th Generation, with XR and SuperG
32 bit mini-PCI type III (PCI Interface v2.3)
Complete Atheros SuperG and XR Feature Set
Enhanced Temperature Rating
data rates 108, 96, 72, 54, 48, 36, 24, 18, 12, 11, 9, 6, 5.5, 2, 1
but inside MK show that:
/interfaces
Wireless (Atheros AR5213)
/system resources
device: 00:13.0
vendor: Atheros Communications Inc.
Name: AR5212 802.11abg NIC (rev.1)
ooohh… What is it??
the vendor give me other MiniPCI Card?? >_> oficial reseller here in Peru trick me??? x_x
how can I check if the card have 108mb/96mb/72mb data rate? how can i put XR and SuperG configuration? how can i use the FULL TURBO MODE OPERATION? please can someone tell me?
You can look up the manufacturer by mac address or vendor here:
https://db.uga.edu/network/public/vendorcode.cgi
The vendor code for Valemount is 00:19:5F (the first numbers of the mac address)
You might be able to Google the vendor and get each model with the full mac address.
please someone help me the official vendor here in peru Comutel, trick me with other MiniPCI Card, i have the Factura with valemount, but the give me the next card, its very similiar, but isnt valemount. this is the mac of my card, isnt valemount. 00:80:48:5E:B6:7E, (COMPEX INCORPORATED in IEEE Registration Authority)
how its possible !!! i trust in the official vendor of mikrotik -.-!!
