From 3.5 billion Reddit comments

Tripp Lite Keyspan High-Speed USB to Serial Adapter, PC & Mac (USA-19HS) https://www.amazon.com/dp/B0000VYJRY/ref=cm_sw_r_cp_apa_yoGKBb3XE45Q6

This one works with windows drivers out of the box. USB cable is removable so you can make the cable as long as you want plus the length of the serial cable.

This Tripp-lite one.

I have purchase history from 2011 of this one, so far I have purchased over 20 of them for every team member over worked with over the years.

Not one time have we found anything it was incompatible with.

This is the best rs-232 to USB converter I've used if you only need 232. Absolutely no disconnects to AB gear like the cheap adapters do.

I don't have experience with those scanners in particular but if it has a regular serial db9 pinout you should be fine using any USB to Serial adapter. I've had good results with these ones:

Good luck, what are you scanning?

I've always went with this and it's never failed.

With a standard cisco blue rollover cable you can find in any cisco box.

Or find it here

PS: I've used one of these for almost 10 years now for Serial access:

I keep it in my bag along with various other adapters and cables and such.

USB to Serial: Example 1 - Example 2
Cisco Console Cables: Console Cables

A word of caution:

You are six months away from the official End of Vulnerability & Security Support for the 5548UP.
So, I'd budget to replace those devices next year if you can.

The situation you describe kind of suggests you might have an ACL on the IP Management interface that is rejecting your attempt to login via SSH.

So, I'd connect via the serial console port and see what is going on in the config.

I'd buy two of these:

And a handful of these:

https://www.amazon.com/CAB-CONSOLE-RJ45-Cisco-RJ45-DB9/dp/B00SWPR4VI/

Don't just buy one of each.

Put one complete console cable in your laptop bag and the other stays in the data center / server room, in a very specific place forever under penalty of death.

If it's 3am on a Thursday Morning and you roll in to investigate a suspected LAN failure, you are helpless without a working console cable.
If you took your cable out of your bag for some reason, that permanent data-center-use-only cable HAS to be in it's spot or you're going to have a really hard time troubleshooting the switches.

You will connect the console cable to the console port:

I've been having soccer issues with the new windows drivers too. I'd just use a trusty old Keyspan. Baring that, run a VM with Linux.

Every member of your team that supports networks gets one of these for their laptop bag, plus one spare unit that stays in the server room - removal of the server room's cable is grounds for execution.

TrippLite Keyspan USB to Serial @$28

TRENDnet TU-S9 USB to Serial @ $15

Pick a standard, and stick to it.

They will need that adapter to get into the console ports of network devices, firewalls and some appliances.

To go with that, every one needs one of these too (not a whole pack, just one coupler):

RJ45 F to F coupler, CAT6 rated

I like the beefier ones and I like them in a slightly easier to see color than black.

Every member of the IT staff that you think MIGHT be involved in a Disaster Recovery or Business-Continuity event should be issued a laptop (with two power bricks), and they should be instructed to bring it home with them every single day.

The penalty for leaving your laptop in the office is a full dozen good donuts. No, not grocery store donuts. The good ones.

The same penalty should be mandated for any member of IT who leaves their system unlocked AND is physically out of sight from said device. This policy MUST apply to you too.

Yes, laptops are more expensive than desktops. It's a necessary BCP/DR expense. Pay it, or you'll be really, really sorry someday when some of your best people are standing around with no way to help recover the business after the fire / tornado / hurricane / truck explosion event.

Don't issue IT "special" laptops. Everyone gets the same physical device (model). But if they need 16GB instead of 8GB, and 512GB or 1TB instead of 256GB, that's valid.

You don't want VP of Accounting asking why IT has better looking laptops than their people receive. That's not how good relationships are made.

One standard for all.

Back when I was more hands-on than I am of late, I'd say add a decent 2 x AA or AAA flashlight (an LED maglite is fine) and a good 6-in-1 screwdriver for everyone.

There should be a simple set of hand tools in the server room.

They can be Harbor Freight, don't have to spend a fortune. But you don't want your people to feel the need to bring in a cordless drill or a socket set from home to do their jobs.

That stupid set of $149 hand tools that you're probably not sure they need sends a respectable message that you are trying to provide them everything they might need to do the things you ask them to do.

Buy a rattle-can of neon green or pink spray paint when you buy said tool-kit and tell somebody to take the tools and an empty cardboard box way out deep into the parking lot and spray a nice splat of neon paint on all the tools that Facilities or Warehouse crew might try to accidentally wander off with.

If you will be repairing laptops on-site, you're gonna want to buy a set of specialty screwdrivers from iFixIT.com too.

Go here and request printed catalogs:

If your people need storage containers, or a good utility cart, buy it from them.

On that note:

Your people NEED at least one utility cart with pneumatic (inflatable) tires.

You can safely transport laptops and monitors on a cart with hard plastic or hard rubber wheels.
I'm not saying it's wise or healthy, but you can.

But a $75,000 network chassis or storage array should not be subjected to that much vibration.

The $300 you spend for this is money well-spent.

The two units I see consistently good performance with are:

TrippLite Keyspan

TRENDnet TU-S9

The Keyspan uses a somewhat unique Texas Instruments chipset while the Trendnet uses a Prolific chipset.

I hear lots of people complain about Prolific chips and fawn over FTDI chips, but I've never had a noteworthy issue with a Prolific chip device.

I've never used this one, but if you want an FTDI adapter this one should be good:

StarTech

Two questions:

What does CPU load on the switches look like?

show processes cpu history

What does CPU load on your laptop look like?

I have seen some USB RS232 adapters drive CPU to the roof.
A reboot of the laptop sometimes resolves the issue, but the root issue is a low-quality driver for that particular adapter.

That is the best USB-to-Serial converter on the market. If it doesn't work with that, it won't work with anything.

Yes, this. I wrote a howto on installing globaltis and tis2000:

https://www.saabcentral.com/threads/setting-up-tis2000-and-globaltis.665465/

It's written for bare metal Windows XP, but there's ultimately no reason it won't work on a virtualbox etc. Windows XP or any bare metal 32-bit Windows OS. I know it's been used to run under Windows 10 32-bit. Similarly, if you've got a physical serial port you'll have the easiest time, but this *specific* adapter works very reliably:

No no no, you misunderstand. I wasnt using a USB mouse.

When i was testing my Serial mouse i used a usb adapter to test on my main computer (ie, giving my primary computer a temporary serial port).

Both mice i have i got here. I got 2 of them, so they are exactly the same.

And i dont remember having this much trouble getting mice to work in the 90's lol. And this a DX4-100, but i think the board is out of a gateway computer. (tho back then i dont think it would matter too much).

Is there an option on amazon? This website seems to be closed for the next month or so.

Something like this?

I recommend this USB to Serial adapter and then you can use the correct 9 pin to 8 pin serial cable for the MicroLogix.

You are going to need the serial connection.

Get one of these if you don't have one already, it's worth the money. http://www.amazon.com/gp/product/B0000VYJRY?ie=UTF8&tag=somethingelse-20
