I remember the old-style conflict monitor cards that came with a diode/jumper matrix, and you cut the necessary ones out to program it. Only thing is, if they failed open you could have a hazardous situation... hence the revised style.
I'm one of those, that are thinking, there has got be a better/different way of doing this. Someone else mentioned DIP switches, and you said you weren't a fan. It seems like it would be easier to carry around something like jumpers, and just have little terminals you could connect the jumpers too. That gives you both physical and visual verification of that link being "jumpered" or not.
Your videos are so interesting. It always baffles me how people dont understand traffic lights, but then i realize i watch different youtube then others haha
I'm curious as to why they don't implement DIP switches instead of manually soldering jumpers, besides cost savings of course. Is it a matter of like preventing accidental setting of jumpers?
@@moosescorner there’s test cards that has dip switch. I don’t personally like that because one wrong flip of a switch can allow conflicts in the field
It's called a program card as in hardwired, and is the last defense in safeguarding motorist & pedestrian from a conflict. Soldered jumpers leave nothing to be accidently switched, and no dip switch contacts to get contaminated and make an open path. That's my take on it.
2:40 programming a safety monitor based on a controller's data is completely inappropriate. You _have_ to use an independent source of information -- copying thwarts its logical redundancy! When you ask a controller what situations it might produce, it _will_ list all of them: and not just the ones that are safe, but also any dangerous situations it could produce due to precisely the sorts of programming errors a safety monitor is meant to defend against!
@@AJMansfield1 well this is not for inexperienced techs you need to be knowledgeable of the system, phases, and controller programming to make sure your references are correct.
Great job for a vampire you do a great job! But I guess you can't be a vampire because you get to work in the daytime you are a 24-hour vampire. Have a great day you did a great job😂
I see these 'bell' shaped cameras all the time in my neck of the woods, and I've been told they're to check if the intersection is cleared, is that true? Not sure if you have them down by you, haven't seen one in any of your videos yet. Curious what the FOV is.
If the mmu or conflict monitor in this case is removed from the system then it's supposed to default into flash anyways. But you want to be able to control that manually.

Cold solder joint on a critical part equals no Bueno sir
Best soldering tutorial I've ever seen. 😏
@@jovetj I enjoy the part when my arm is in the way from showing anything! 🤣 I do what I can with what I have though! Thank you!

Great Update and Thanks for the explanation. 👍🙏

But! There are things such as open and cold solder joints that can develop over time...
@@jbsimmons54 that would cause a fault which is the better option then allowing a conflict.
Wait, so you spell out the letters (m,m,u)? I thought that it was pronounced like a stuttering cow (m-moo). 😜
ty for this informative video
16 channel mmu not 16 phases. Good video, keep it coming
@@stevedomanski31 you’re correct and thank you!

Man that looks like that soldering iron seen better days
Yeah bout time for a new one! 🤣
You should do a video on the phases in an intersection.
What does MMU stand for?
Malfunction Management Unit
That's rather goofy that you need to be soldering jumpers vs removable jumpers like you find on motherboards and such...

This looks like an nema cabinet. Do you see many ATC cabinets?
Interesting!
He actually identified a major bug in this stream but failed to notice its implications.
IF i remebr right, sure it was this one.
What would happen if the traffic signal isn't switched over to flash mode prior to swapping out the conflict controller? 🤔

4 More phases cool beans 🫘🫛 to make it ready for the update on the 4 way intersection when they do it
