RS-232 Serial port to RJ11 (maybe RJ12).
Lots of possible devices such as a 2-line LCD display, scale, barcode scanner, cash drawer, etc.
Pretty common in PoS (Point of Sale) systems.
>RJ11 (maybe RJ12).
Actually, it's RJ10, which is the same connector you'd find from an old telephone handset to the base. You can tell because it's only 4P4C, rather than 6P2C/6P4C like RJ11, or 6P6C like RJ12.
Exactly me! I could've upgraded but i couldn't justify an expensive second monitor so i sold my old monitor when i upgraded and kept using the same old second monitor
That is a console cable. Its primary use is to configure switches. For example a Cisco network switch that is about to be deployed into a corporate network. The network part is a RJ 45 (or relative depending on equipment) connected to the network switch "CON" port and the part that looks like a VGA-adapter is a DB9 serial adapter. You need a special serial card in your PC or an adapter to hook that to a laptop.
The picture on my screen is not clear enough to tell the number of pins on that keyed RJ45. Cisco was an example of a manufacturer who uses this category of cables.
DB-9 doesn't exist. People sometimes call it that, but it's incorrect because it's DE-9. The shell size is E and it has 9 pins. B shells are much larger.
That's just a you problem. The whole rest of the world calls it DB9 because that's what it is. Only a weirdo would say, but actually it used to be called a DE9. Cool story bro.
This is a DB9F to RJ10 cable. Those are used to connect Meade Autostar telescopes to PC serial ports and use your favorite astronomy software, but they’ve also been popular with UPSes.
We're both correct. Serial port cables can also have an RJ45 connector at the other end for data communications with peripherals such as steering wheels, pedals and shifts.
But this isn't an RJ45, but rather an RJ10 (the same you'd find connecting a wired telephone handset to the base). Not saying there aren't any, but I've never seen a switch that used this connector.
If you have one of those you must have a box with unused cables in it. Toss it in, seal it, then leave it to one of your kids in your will. They'll love you for it.
Serial cable for these computers:
Sinclair QL and all 128K models of Sinclair ZX Spectrum.
I know this because I am a Sinclair enthusiast who owns several of these machines.
The computers I mentioned all have a receptacle for the [BT631W ](https://www.betterbox.co.uk/images/1/1/CT6310.jpg)plug used by British Telephone.
Some older UPS systems would use these for serial communication to the connected computer. It would allow for the computer to monitor the battery status of the UPS and give the computer time to shutdown if power loss was inevitable.
It's probably not a console cable, as many have guessed, because that's an RJ-11 jack, not an RJ-45.
I think it's likely a proprietary serial cable (eg Palm Pilot) or a UPS cable.
Its actually crazy to think that i am actually this old :)
This Once used to be an everyday sight in my fathers office :)
And now theres are generation of ppl who dont even know that
Once there were balls inside mice
Keyboardz and mice both didnt use the usb
Hdmi was a thing of vv distant future :)
Pendrives were like the most advanced tech to be seen :)
A Serial Cable with RJ Link? It's probably for older equipment that would be used in Laboratories, Hospitals or Industrial Equipment. It is also used with older networking equipment.
its a type of cable I know as a console cable. seen it on really old switches and networking gear for administering it locally before you get a remote admin option available, like first boot.
its just a fancy serial cable, but hold onto it. I already know you'll use it exactly once, but it will absolutely save your life when you need it
I had the same for some old ups, and some switches, also seen some old timey barcode scanners with this. Reliable, but not gonna cry, if i newer use it again.
As others have said, it is a serial cable, another use other than Point Of Sale hardware is a battery backup unit (UPS) to control graceful shutdowns to the computer when power cuts out.
First of all, fuck me, I’m old. It’s a peripheral interface for those LCD stick displays on cash registers. Could also be used for barcode scanners, ticket printers, cash drawers (sending an open signal to them and logging times that the drawer was opened), and lots of other niche uses.
That's possibly for an old rs232 handheld barcode scanner, being db-9 and rj-11(?) on the other end.
Sometimes these came with old switches to program them, however the size of the rj connector makes me doubt it a little
Back in the day there was also a few CAD mice, modems, and really friggin old crt (vt220?) Terminals that took these. But the black plastic makes it more "modern" circa 2000's....everything was grey or beige in the ancient times bc of the "natural" colors of the plastics used
First of all: fuck you, I'm not old.
Second of all: It's an RS232-RJ11 to DB9 cable. We call them terminal cables over here. They allow for a local connection from an external station to a serial interface of a network device like modem/telecommunications via PC. We've primarily used them for terminals or telescopes.
No one asked. DE9 refers to size (and pin/hole count), while DB9, although technically being a misnomer, is something everyone understands.
So it is a DB9, while not being *a* DB9.
If not VGA,why VGA coloured?
At least this one makes some sense. I have a cable that's RJ45 to USB. It fits perfectly in an RJ45 port, but it has only 4 wires connected and no active electronics in it.
It looks like a VGA to RJ-sth cable. Pretty weird for a port specialized in network transfer and a port dedicated for image export to be in a single cable.
It is a console cable. One end is a standard COM connector that would connect to a terminal port on whatever piece of equipment it goes with (typically cisco switches). The other end is ~~RJ45 to connect to ethernet~~ RJ11 to connect to a modem port on a PC. It allows the PC to access the devices console (command line) to manage its settings.
Not enough pins on either plug. It's a 9-pin Serial to 4-wire RJ11 (phone connector). A lot of old devices that needed more compact connectors than 9-pin would use serial over RJ11 to communicate with the host controller or computer.
Yeah right I don't even know what these are called bruh... I just know I have THAT blue oort plugged in to my monitor,the other end connected to my PC, that's all
One port does not make a whole cable.
Moreover, modern VGA has 15 pins, not 9.
This is a crossover cable that was never and will never be used for a monitor.
Wait...pins! That's it! I just gotta check if its 9 or 15! ...wait...modern VGA cables has 15 you say? So like, I won't be able to use my current 16 year old monitor on the PC I'll be building?
RS-232 Serial port to RJ11 (maybe RJ12). Lots of possible devices such as a 2-line LCD display, scale, barcode scanner, cash drawer, etc. Pretty common in PoS (Point of Sale) systems.
I'll see your PoS (Point of Sale) and raise you PoS.
Hey! That intel atom is trying it's best.
Poor little beast.
>RJ11 (maybe RJ12). Actually, it's RJ10, which is the same connector you'd find from an old telephone handset to the base. You can tell because it's only 4P4C, rather than 6P2C/6P4C like RJ11, or 6P6C like RJ12.
Also common in networking, that's the only time I've used them, as a console cable
its is also used to connect an analoge Modem , or an accoustic coupler
It’s used to manage enterprise networking equipment cable is an RS232-RJ45
I know what rj11 is but what is rj12?
Like RJ11 but with 2 more conductors
not just RS-232, the serial port can be used for RS-485 aswell
i almost thought that was an vga cable for a sec
Had to do a double take after seeing top comment, now a triple take for this one smh.
Their fault for making it blue which is the colour for vga in the same size connector, just a different pin setup.
Ya I was about to freak out if people don't know what a VGA cable is. I'm going to feel old. Obsolete cable though so the day is near.
I still use a VGA monitor as second screen, it's connected with an adaptor cause modern graphics cards don't have VGA ports.
Exactly me! I could've upgraded but i couldn't justify an expensive second monitor so i sold my old monitor when i upgraded and kept using the same old second monitor
Jesus Christ sometimes I can be very toxic. Thanks God I came to read the comments first.
That is a console cable. Its primary use is to configure switches. For example a Cisco network switch that is about to be deployed into a corporate network. The network part is a RJ 45 (or relative depending on equipment) connected to the network switch "CON" port and the part that looks like a VGA-adapter is a DB9 serial adapter. You need a special serial card in your PC or an adapter to hook that to a laptop.
The Cisco console cables (and many others at this point) use an 8 pin modular connector, not 4.
The picture on my screen is not clear enough to tell the number of pins on that keyed RJ45. Cisco was an example of a manufacturer who uses this category of cables.
The image itself is very clear, and it's an RJ10 connector, which is only a 4P4C connector. Not sure why it's so hard to make out for you.
Now we sort the Telnetters from the Tera Termers!
We always called them terminal cables. Works with standard rs-232 no special card needed just a motherboard that has a serial port.
I mean if your standard office PC didn't have a serial, you'd get a serial card and put it in. For someone not in networking I'd call it "special".
I gotcha bud. Just wanted to clarify it, not insinuating you don’t know your craft.
Regardless its a 4-pin RJ connector not an RJ45 so it's all moot anyway because that's not what this is.
Oh, that's not VGA. Ok smh DON'T MAKE IT BLUE
There trouble if you rely on color for any cable. VGA isn’t always blue. Now Cisco console cables. Those are always special
That is a rs 232 db9 connector, kind of like an old usb
DB-9 doesn't exist. People sometimes call it that, but it's incorrect because it's DE-9. The shell size is E and it has 9 pins. B shells are much larger.
That's just a you problem. The whole rest of the world calls it DB9 because that's what it is. Only a weirdo would say, but actually it used to be called a DE9. Cool story bro.
Also Is a serial port
This cable is used to remind people born before the 90s that it's time to get a colonoscopy
Can be a UPS communications port, I use the same on mine except it's USB and not serial
Technically USB is just that serial cable but in a nice new form
And not RS232**
RS232 is also just a form of serial communication wire
Yeah and it's correct. Also port, not wire
It would be connector then
...still correct?
What's the difference
Akshually it's the name of the protocol
I read it indeed. The name of the piece of plastic at the end of the wire is called a female DE-9
>nice new form And more nearly... universal.
Rs232 or rs485
My back hurts
This is a DB9F to RJ10 cable. Those are used to connect Meade Autostar telescopes to PC serial ports and use your favorite astronomy software, but they’ve also been popular with UPSes.
Serial port cable for attaching older printers, scanners, 56K dial up modems, etc.
No it isn’t. It’s a console cable.
It's all serial. They are functionally the same.
We're both correct. Serial port cables can also have an RJ45 connector at the other end for data communications with peripherals such as steering wheels, pedals and shifts.
Yeah okay, you're totally right. I've got a bit of experience with sim racing setups, but this was something that I'd never even considered.
Neither did I until I bought a Thrustmaster steering wheel set.
But this isn't an RJ45, but rather an RJ10 (the same you'd find connecting a wired telephone handset to the base). Not saying there aren't any, but I've never seen a switch that used this connector.
This!
It's been a while since I've seen this one
I just tossed one of these at work.
It’s how you link horses together for combined horsepower.
God I feel old
If you have one of those you must have a box with unused cables in it. Toss it in, seal it, then leave it to one of your kids in your will. They'll love you for it.
Used to program Telcom equipment with a PC's rs-232 serial port. Access to the equipment menu with modem (terminal) software like telnet or procom.
Had an old alignment machine that used this cable for the hand held scanner for vin plate.
I work in Data Center. We use these to hook up a server to a laptop so customers can remote in to their servers.
It's a console cable. I've used it them configure Cisco switches.
That’s not a Cisco cable. They are RJ45 (8 pin), not RJ-11 (4 pin) and they are always teal.
Hmm, maybe they were Samsung switches then..
Could be an APC console cable
This is like someone taking out a VHS and asking "what's this?" It just makes me feel old...
It's for viewing the matrix code.
Attach it to Johnny 5.
Tell me you are born in the 2000 without telling me you are born in the 2000

You plug it into your butthole. RJ45 is for broadcasting worldwide how it went :P
It lets you use an old, rotary phone as a serial trackball device.
I saw one on an old cnc engraving machine. Running xp with manual port settings. I highly recommend leaving it TF alone!
It connects the microwave to the record player
Started to say, "I was there, Gandalf..." but, it is not what I thought it was.
APC UPS devices had these RJ to rs232 cables for ups management.
I have this type of cable. It was in my grandparents house for some reason
Thanks for making me feel old asf
It's a museum piece
Holy fuck I am old
RJ-to-DB9 COM cable. Used to configure headless servers, switches, and other devices that take COM input.
One end serial, the other phone…. Dials into Matrix. Get me a connection.
Some older UPS systems would use these for serial communication to the connected computer. It would allow for the computer to monitor the battery status of the UPS and give the computer time to shutdown if power loss was inevitable.
Data cable.
My god I feel old
It's probably not a console cable, as many have guessed, because that's an RJ-11 jack, not an RJ-45. I think it's likely a proprietary serial cable (eg Palm Pilot) or a UPS cable.

Sweet summer child
i feel old AF

I already know you'll use it exactly once, but it will absolutely save your life when you need it
A comms cable to connect to something that has a built in io interface for configuration.
RS 232 serial that one
I had the same for some old ups, and some switches, also seen some old timey barcode scanners with this. Reliable, but not gonna cry, if i newer use it again.
to what is going on in the router via a monitor (i am joking i have no idee)
I've seen a similar cable on a steering wheel game controller. It was used to connect the pedals to the wheel.
It's there to confuse, mystify, and piss off those who find/use it
Basically the really really old version of usb. If you don't know what it goes to you probably don't have a use for it anymore
Both of those are used in some of my old Logitech steering wheels and joysticks
Its for serial connect to device with RJ connection
[удалено]
It's not a vga connector. It's a serial cable.
I work with industral control systems, and we use this to connect a thermal printer to an HMI display interface that connects to a PLC
That’s how you enter the matrix in legacy mode.
Isn't that a rollover cable? Used a lot to connect to console ports on networking equipment like cisco routers and switches.
As others have said, it is a serial cable, another use other than Point Of Sale hardware is a battery backup unit (UPS) to control graceful shutdowns to the computer when power cuts out.

Kvm
It’s not just the drawer that’s old…
A Saab Tech 2 uses one of these cables. However, the end is RJ45, not RJ11.
Serial cable for huge number of devices. I don't see anyone mentioning that it can be for an inverter as well, so thought I'd drop the comment
That's possibly for an old rs232 handheld barcode scanner, being db-9 and rj-11(?) on the other end.

Mouse
Maybe a UPS monitor cable?
I’ve always seen it referred has a vag cable
Yes, the vagina cable. You're right.
Serial console cables are used for industrial equipment configuration.
very old cable, used to connect serial port to your fixed landline telephone. used mainly for a fax modem
So that you can display your internet connection on a monitor obviously /s
You're not entirely wrong
I legit didnt see the other end of it and i was like "no fuckin way im this old"
serial cable for a pdu
Basically ~~display~~ data over network, it is used for remote ~~screens~~ consoles.
DB9 to RJ45 cable
First of all: fuck you, I'm not old. Second of all: It's an RS232-RJ11 to DB9 cable. We call them terminal cables over here.

It was the first VoiP cables released that included video conferencing.
It's a VGA to ether....wait whaaa..
Probably connects two things together.
A printer and a broadband router got together and made that cable
Serial cable
Bruh.... I thought everyone knew bout this feeling old (im 23)
If not VGA,why VGA coloured? At least this one makes some sense. I have a cable that's RJ45 to USB. It fits perfectly in an RJ45 port, but it has only 4 wires connected and no active electronics in it.
you can connect this to your laptop with tv or LED
To connect one electronic device to another to transmit some form of data.
Seeing this question asked makes me feel old….
It goes from a point of sale machine to the till to unlock and open it.
This is an incense stick holder, pretty handy can hold a lot of them separately.
Holy shit im old
I use these for a PDU (PDU41001)
Im only 22 and this made me feel old
this cable is to hook up your router to an monitor (this is false its an joke)
VGA?
Data Com port - telephone jack wall plug
It looks like a VGA to RJ-sth cable. Pretty weird for a port specialized in network transfer and a port dedicated for image export to be in a single cable.
not as fun as parallel port networking. Connecting two PC via printer port.

Looks like serial cable for apc pdu.. heh
Gen 1 hdmi
Damn I feel old.
Cann communication between car computer interface and laptop computers. Pcan explorer and similar software.
Making me feel old
Look inside your router’s soul?
It is an old VGA Cable for Connexion to onder videomonitor.
it displays the ethernet
The times before digital monitors
someplace to use the dvi adapter :)
It’s not a DVI cable; it’s a DB9 with RJ11. Likely used in some POS machine or something like that…
hey that's no way to talk about the machine! /joking
I know, right! When the “pos” was promoted to slang I was wondering why are they talking about point of same terminals all the time 😂
I stand corrected, I thought it was a vga cable.
To plug into stuff….. 😐
~~VGI that you plug into pc and monitor or pc and projector, it have 2 screws you need to screw when you plug it~~
NVM im dumb and blind
Is thin question for real lol
Isn't this VGA,or am I dum?
That's not VGA, not enough pins. That's a serial connector.
You're right, there aren't enough pins. Thanks.
No, no your right
No he's not, only 9 pins, it's serial
[удалено]
Not enough pins on either plug. It's a 9-pin Serial to 4-wire RJ11 (phone connector). A lot of old devices that needed more compact connectors than 9-pin would use serial over RJ11 to communicate with the host controller or computer.
A monitor cable. Haha I have that connected to my 16 year old PC and monitor
No.
I can prove it
Except you are wrong.
Brother... I literally have that cable plugged in rn in my PC with my monitor :/
Except you don't, Did you even see the connections on it? Your PC has a RJ11 jack for a monitor? I know it doesn't.
Yeah right I don't even know what these are called bruh... I just know I have THAT blue oort plugged in to my monitor,the other end connected to my PC, that's all
One port does not make a whole cable. Moreover, modern VGA has 15 pins, not 9. This is a crossover cable that was never and will never be used for a monitor.
