Welcome to another informative video brought to you by RealPars.

Today you will learn about RS 485.

If you are familiar with RS 232,

then you may already know a little bit about it.

If not, check out our other video What is RS-232.

Just like it's older brother RS 232,

RS 485 is a form of serial communication.

Think of RS 485 as the younger, faster brother of RS232.

What made it such an advancement over RS 232

was the fact that it could transmit not only a single device to device transmission,

but also a communications bus to connect multiple devices at once.

The configuration and specifications of RS 485

make it faster and extend the range of data transmission.

You aren't limited to fifty feet of cable like with RS 232.

The maximum cable length for RS 485 is typically listed as 1200 meters or about 4000 feet.

Much like RS 232, RS 485 doesn't have an actual standard connector.

Many times the old DB-9 connector is used.

In some applications, terminal strips were used in place of a connector.

This helped RS 485 become a widely used

and very versatile form of serial communication.

Another advantage over RS 232 that I mentioned earlier

is the number of connectable devices.

RS 485 can handle up to 32 connected devices.

RS232 could only handle one.

This allowed users in manufacturing facilities

to connect larger applications and whole machines with one protocol.

Another plus for RS 485 is that it is less susceptible to noise issues.

Electric noise can cause all kinds of problems for electronics.

RS 232 referenced ground to decipher the data it was transmitting.

This allowed for electrical noise to cause interference.

RS 485 avoids this issue which also allows for shielding of the cables to prevent noise.

You may be wondering, what can I do with serial communications, especially RS 485.

One very common example in the automation world

is remote control of VFDs or Variable Frequency Drives.

Many people just call them motor drives.

A simple network of a PLC, VFD,

and an HMI allows remote control of motors in an industrial setting.

Let's say you were monitoring a water pump filling a vessel.

You decide that the water is not filling fast enough to keep up with demand.

With your RS 485 network, you can remotely monitor

and control that pump from a control center.

This is possible since the HMI is connected to your PLC via RS 485.

The PLC is also connected to the VFD via RS 485.

The PLC is programmed to monitor the level of the water in the vessel.

It also allows manual flow control if needed.

All of this allows you to speed up the VFD

that controls the speed of that water pump.

Problem solved thanks to RS 485 communications.

Let's talk about what we now know about RS 485.

It is faster and much more versatile than the older RS 232.

Users can utilize a longer cable, up to 1200 meters or 4000 feet.

The greatest feature of RS 485

is the fact that you can connect up to 32 devices on one system.

RS 232 could only handle one at a time.

There is no standard connector for the protocol.

Most manufacturers still utilize a DB-9 connector.

You can also still simply use a terminal strip.

This makes utilizing RS 485 simple.

All in all, RS 485 really allowed full automation possible

with its ability to connect so many devices at once.

I truly hope this video was helpful.

What If SCP 087 Was Real? - Duration: 6:09.

Hello internet and welcome back to the most inquisitive channel on YouTube life's biggest questions the place where our security clearance is most definitely

Aboveboard none of a credentials are forged and we definitely don't poke our noses where they shouldn't belong what's going on guys as always

I'll be your disembodied floating voice Jack Finch as we dive back into the depths of the SCP foundation

figure out just when the hell we're going to give up this ruse as we peel back the soundproof padding take one step forward and

ask the question what if

Scp-087 was real roll the clip

It wasn't there

I wish she'd go away in

1899 inspired by the reports of a strange eerie ghost that would constantly run the stairs of a haunted house in Antigonish

Nova Scotia a poet named William Hughes mearns famously penned his poem the little man who wasn't there it inspires in a strange

Ethereal sense of equal parts familiarity and the uncanny but like with most things the world of the SCP foundation

Takes that feeling one step further enter SCP 0 87 an old boy

You better just keep walking before we slide on down into that though

You know the drill by now guys, if you're a fan of this video the SCP foundation

John, cusack maybe or just lbq in general then go ahead and give this video a thumbs up and ding that subscribe bell

So you can stay up to date with our latest and greatest

uploads if you'd like to get in touch with myself

And the creative team here at life's biggest questions then take a peek at the info box down below on with the show

Have you ever been walking down a staircase?

perhaps late at night when you get that strange eerie feeling that something or someone is following you not in the sense that

Footsteps are in pursuit or echoing voices, but that feeling that you're being watched in such a tight space

Well, let me introduce you to scp-087

And those fears will soon be mutated into a much more

desperate beast 0 87 is a euclid class amorphous object located on the campus of an

undisclosed United States university that appears to be an infinite staircase the doorway leading up to scp-087

is constructed out of

Reinforced steel with an electric release lock the mechanism on the doorknob will not release unless it's given a redacted amount of voltage

That's a measurement in conjunction with a counterclockwise rotation of the key

It's been disguised to resemble a janitorial closet consistent with the design of the building sounds harmless enough while it's pretty important to note that

Absolutely. No personnel are permitted access to scp-087

On account of the horrors that lie within and that's not despite trying believe me in layman's terms

SCP 0 87 is an unlit platform staircase and despite the large amorphous

Ghostly face and the incessant small child crying in the darkness as about as unassuming as it comes

Alright, we forgot to mention that right, right

Each staircase is roughly 13 steps descending at a 38 degree angle before reaching a semicircular platform

approximately three meters in diameter and that's it on and on creeping forever downward toward who knows where the design of

Scp-087 limits subjects to a visual range of approximately one point five flights of stairs

and there are no

Lighting fixtures or windows present lighting sources brighter than 75 Watts have shown to be ineffective as the staircase itself seems to absorb

Excess light itself of the four expeditions that the foundation have operated on scp-087 each of them have reported and confirmed the distressed

Vocalizations of what is presumed to be a child of an indeterminate age

Expeditions and video feeds have also confirmed the existence of an SCP 0 87

1 an amorphous entity which appears as a face with no visible pupils nostrils or mouth and that's about all we know of it

Which is terrifying, right?

It poses an incredibly interesting question

Which I think rests on the function of Class D personnel and their role in the Foundation's

Experimentation in zero 87's Canon for Class D prisoners have been sent into the staircase one of which survived one of which became

Comatose and two of which are now deemed m.i.a for intents and purposes

You could likely say that SCP 0 87 is a sinkhole for human resources

Pardon the pun think about it

Even an unexplored cavern has an ending right scramblers and cave divers alike willingly plunge into the unknown

Risking their life because there's a thrill in exploring the unexplored. But what about the unexplored?

It's human nature to want to conquer curiosity how it's the sole function of the foundation itself

If you really break it all down. But how far would that curiosity go? What would be the ultimate price? We'd pay for an answer?

Essentially how many Class D personnel would it take to get the answer?

Yeah, I hear what you're saying

If an infinite cosmic staircase was real and we knew that there was a creepy floating head somewhere down there

We'll probably send a drone or a bomb disposal robot down there before we start sending down meat sacks, but come on

That's not the foundation style

we all know that why build a robot when you can use a Class D which demonstrates much more movability and you

Sentience also I guess they serve a function in themselves

But this is really where we get to the crux of our answer just like the poem by William Hughes Mearns last night

I saw upon the stair a little man goober you want to do oh how I wish you'd go away

well, that's exactly how we deal with things because that's how the foundation deals with this particular enigma ignorance is bliss if

Scp-087 was real we'd seal the door and leave it shut because some things are just better left unsolved, right?

Well, let us know what you think in the comment box down below. Cheers. We're sticking around all the way to the end

What really happened as Arsenal vs Man United YouTube match is abandoned - Duration: 2:54.

has opened up on the YouTube football match between Arsenal and Manchester United that had to be abandoned

  Teams from Arsenal Fan TV and The United Stand came together on Sunday at White City in London

 The United side won the encounter 3-1 after it had to be abandoned when three players from Arsenal were sent off

 Mr DT, who has shot to fame on Arsenal Fan TV, claims he was sent off for shoving the referee which left his team with eight men

 The row over the encounter has continued on social media amid calls for a rematch between the two sets of teams

 Goldbridge has offered his side of the incident and sent a warning to his rival

 "It was very surreal what was going on. I have seen what DT said and I have watched the clip," he said on his YouTube channel

 "If you can do something, and get away with it, when someone gives you a dig, that's what it is all about  "He was trying to get at me

I don't need to start fighting him.  "You lose your head on the pitch and you end up off the pitch

 "If you get sent off, you are probably going to lose the game. I have always been quite petulant but quite clever

I would never aggressively go in on someone."  He went on to add: "It is a shame the match had to be cancelled because of a few red cards

There were some regrettable things  "For me, what happens on the pitch stays on the pitch

 "Football is a passionate game but you have to control it. It is finished now - there is an L and there is a W

 "I understand his negativity and moaning but you have to take your medicine and move on

"  Mirror Sport columnist Stan Collymore even waded in on the encounter and hailed Goldbridge for his victory

The Feeling is the Secret Guided Meditation LISTEN TO THIS DAILY - Duration: 26:47.

this video I'm gonna be sharing with you a feeling is the secret guided

meditation that will help you to achieve your goals I believe if you listen to

this meditation for the next twenty-one days it will totally transform your life

welcome back to another video my name is Aaron and I help people to expand their

consciousness now in this video I'm gonna be explaining to you the power of

what it's called the feeling is the secret book by Neville Godard I'm gonna

be sharing with you a meditation at the end that you can listen to every single

night that will help you to achieve your goals

now that's gonna be actually a majority of this video but for the first couple

of minutes what I wanted to do is to share with you how to use it and what

the idea is behind the teaching of neville goddard and how it works with

the feeling is the secret now this is a book that i originally read about five

or six years ago it's a short book it's about 60 pages long and when I read it I

started to really become aware of this window of time before I go to bed at

night and it's the same for everyone as you're going to bed at night what is

happening is your brainwaves are going from that of more of an alpha beta state

which is the more awake States into the deeper levels of consciousness so you're

going from Alpha and Beta into more of a theta state and as you're moving more

into theta Delta State Delta's more of the sleep state theta is more of the

really relaxed meditation state what we're doing is we have this ability to

influence our subconscious mind in a very powerful way and we do that with

feeling the language that the subconscious mind speaks in is the

feeling and that's why the feeling is the secret most people are intending to

change their subconscious mind using logical thoughts but that doesn't work

because that's not the language that the subconscious mind speaks in so many

times we can sit there all we want and say something like I am abundant I am

abundant I am abundant but if we don't feel the abundance underneath that

that's when we move that into what it's called an

incantation when sometimes we can even use our body to change our physiology or

to change how we feel well we begin to do is we begin to then

influence that part of our brain which then begins to influence our life now

understand our subconscious mind runs over 90 percent of our life experience

so when we get to the core of our subconscious mind and we learn how to

influence it everything in our life can change and if you look at it like this

as well when we grow up up until about the ages of 8 to 12 years old

we're in predominantly a theta state which means as we're growing up we're

literally absorbing the environment we are attributing meaning to certain

things and we're doing that all subconsciously we're not even aware of

it that's why a lot of times when you see people going through transformation

type work you may see someone like Tony Robbins that ask someone what was your

relationship with your dad like what was your relationship with their mom like

because the relationship with the parents is the first relationship we

normally have and we have derived so many meanings and associations from them

that subconsciously that's what runs our life so even 3040 years later that

person may be still running on that same subconscious type patterning now here's

the thing up until about the age of 8 to 12 years old we're in that data state so

what happens is right around that time we start to move more into the alpha

state we start to move more from the subconscious mind into the conscious

mind and we start to then have this thought process where we can have like

this barrier between what we think and what we experience now what happens is

then we get set on our ways for most of our life experience so the key and the

power is hacking our mind by knowing there are certain times of a day when

our brain is going into more of a theta state when it is drifting into the

deeper brainwave state to win then we can influence it with emotion so the way

we do this is the twenty minutes when we wake up in the morning and twenty

minutes before we go to bed at night because that's the window of time so

what I do and what I recommend you do is you visualize what you want to

experience as if you already have it as if it's already something that's real

for you and you feel that and you put yourself in the visual visualization

right before you go to bed at night and right when you wake up in the morning

there's a couple hacks I'm gonna be sharing with you in this meditation this

meditation that you are about to listen to is going to be one that you can

listen to right when you wake up in the morning and right before you go to bed

at night I have recommend you listen to it twice a day in order to get the

maximum benefit out of it and this will help you to then start to create a more

empowered self-concept a self-concept as a self image we will always be and

consistent to the self image we have we always do that subconsciously so as we

have a thermometer on our wall maybe what you'll do is you'll see that it's

set at 75 degrees if it gets hotter or colder the AC or the heater work will

kick on to put it back to that set point we may try to change but not change our

setpoint so what will happen is we'll try it we'll start gaining success for

example but if our thermometer is set of 75 and we start to get success it'll

kind of pump on and be like yo that's not who you are come back let's stop let

me sabotage you real quick so that you come back to what's comfortable so it's

about being aware of what that is but this meditation will help you to bypass

all of that so this is why I recommend you listen to it for at least 21 days

right when you wake up in the morning right when you go to bed and you put in

a similar visualization each time you do it for things to really become something

that we experience it takes repetition that's why I recommend with this

meditation some of my other meditations you can maybe switch what you think

about because then you still get a powerful effect this one's a little bit

different you want to imagine a similar thing but you need to make it more about

the focus of the feeling but make it something that's a similar outcome

because what manifestation is the power of it it's a combination of an increased

emotion which is the feeling we're going to be generating with an increased

intention these two things make for what we want to experience in our life but

that intention you want to think I intend dot dot dot you want to think

intention be something that's clear something that is specific something

that you can see every single time you this meditation inattention is like a

declaration of a desire that's the difference between desire and intention

desire says I I want something but an intention says I intend it for that

it's declaring it into the universe is the way you can think about it so what

I'm going to ask you to do right now is to take in a deep breath in a deep

breath out and to feel yourself relax what I'm gonna do in a minute

it's cue the music and then we're gonna move deeper and deeper into relaxation

and I'm gonna guide you along this process of feeling more inside of your

heart center and then what we're gonna do is move into our actual visual

visualizations and feeling as if it is happening now so let's go ahead and take

in a deep breath in and a deep breath out I recommend you listen to this

headphone this meditation with headphones if you can so let's take a

deep breath in and a deep breath out

as you breathe out feel your body relaxed more and more now let's take

another deep breath in deep breath out and as you breathe out put your

awareness in your hands over your heart the heart math Institute has shown that

the more attention we put on our heart center the more we grow that

electromagnetic energy around our body that the power of the heart is thousands

of times more powerful than that mat of the head so let's taking another deep

breath in deep breath out now put the awareness over your hearts

and begin to feel inside of your heart center feel the warmth of your hands

into your heart and feel free to close your eyes now if you wish and know that

with every breath you take you are shifting deeper and deeper into

relaxation you are feeling your body relaxed more and more now put the

awareness in your head feel the sensation in your forehead put the

awareness behind your eyelids feel your eye sockets relaxed

put the awareness in your jaw imagine your jaw relaxing let it be loose relax

the tongue feel the awareness in your neck put on your left arm your left and

imagine a wave of relaxation flowing through your head now imagine this wave

of relaxation flowing through your right hand your right arm feeling it relax put

the awareness in your chest and your heart and imagine there's a ball of

energy inside of your heart any color that you like and imagine with every

breath that you take this energy is becoming more and more powerful you are

feeling it increase imagine that this ball of energy is spinning in the

clockwise position and the faster it spins the more you feel this love

imagine it spinning faster and faster

I'll put the awareness in your stomach

imagine relaxing your hips your left leg and foot

wave of relaxation right leg and foot wave of relaxation flowing through your

whole body now imagine that any excess energy in your body or any energy that's

not serving you is flowing through the heels of your feet

imagine that energy flowing through your body and leaving through the heels of

your feet

feel relaxed

now imagine yourself in a very relaxing place this could be a place that's at

the beach it could be a place that's in inside a room you feel very comfortable

and could be outside in nature wherever you want imagine that you are in this

place

as you look around what do you see

what kind of sounds do you hear

imagine those sounds becoming louder and louder pay attention

to how relaxed you feel

now notice at about 15 or 20 feet away you notice a chair

and this chair is one that you can sit in anytime you want to increase the

feeling inside your body of you experiencing what you want now we're

gonna take ten steps towards this chair and with every step we take we're gonna

feel that as we get closer to the chair we feel an increased emotion inside of

our heart center we're gonna feel more love in our heart than ever before I'm

gonna count down from ten to one with every number I count imagine that the

energy in your heart is increasing you're feeling elevated emotion more

warmth and more love take a step towards this chair ten feeling your body now

begin to move in that direction nine with every number I count you feel

double the amount of love inside of your body double the amount of relaxation

eight getting closer to the chair now seven feeling yourself feel relaxed and

comfortable six feeling this energy in your heart increase even more five four

getting closer three deeper into this feeling of love to an increase in your

heart now and one now you are standing at this chair and you can feel the

energy in your body increasing more and more

now pay attention to how this chair looks

and then notice and become aware that you can sit in this chair and do this

meditation anytime you want and that when you sit in this chair you always

feel relief you always feel an increase in the emotion you want to experience in

your life it's very easy and natural for you to do now go ahead turn around sit

in this chair and notice that as soon as you sit in this chair you can feel how

relaxed you feel how much love you feel

there's something about this chair to you that is so easy to feel the emotions

you want to experience

in this chair your feelings are much more sensitive and you can feel positive

emotions more easily than ever before

now imagine some things that you want to experience in your life certain goals

you have and imagine them as if you are experiencing them now not as if in the

future you will but as if you are experiencing them now

imagine what it would look like through the eyes of that version of you imagine

what you would see achieving a certain financial goal a relationship goal

whatever your goals are imagine a scenario where that is happening

what do you see in this scenario and it's experience

imagine the colors becoming brighter and brighter

what can you hear in this experience

imagine those sounds becoming louder and louder

right now you are feeling as if this is happening

soak in this feeling

notice how natural it is for this version of you

these experiences you're in are a part of who you are

now imagine another scenario of you achieving your goal of you experiencing

something you've always wanted to and imagine it as if you're looking through

the eyes of this version of you

now what do you see

Man Utd fans furious at what they spotted Alonso doing before goal - Duration: 2:34.

  Manchester United fans weren't best pleased with Marcos Alonso on Saturday.  The Spaniard was in the box when Luke Shaw attempted to find Romelu Lukaku with a whipped cross, but managed to momentarily clear the danger with his head

 Seconds later the defender dropped to the ground as the ball was played back into the area, where it later rolled into the path of Ashley Young, who fired a shot at goal

 The shot was deflected off Marcus Rashford before colliding with Jorginho and picking out Anthony Martial in the middle

 The France international took the ball down in his stride and volleyed it at goal in one movement

It beat Kepa Arrizabalaga with ease and nestled into the corner of the net.  While all this was going on Alonso remained on the ground

 It's not clear what was wrong with him, and he could well have suffered a knock to his head as well as his ankle, but United fans weren't having any of it

 The laws of the game state that the referee doesn't have to stop play unless a player has suffered a head injury, for safety reasons

 And fans are accusing Alonso of making his injury seem worse than it was in the hope the referee would stop play and end United's attack

 On Twitter, one Red Devils supporter wrote: "Alonso tried to cheat by holding his head

Rightly ignored. Should have been yellow carded."  Another said: "Alonso lying on the floor in the area feigning a head injury when he could have been on his feet stopping United scoring

"  A third added: "It wasn't even a head injury Alonso was holding his ankle."  Bit harsh if you ask us!
