Pipestation USB to Serial Adapter Cable 1m - Connect Legacy Devices RS232 for Modems, Printers, Cameras - Male to Male

I used this successfully to talk to an old Cisco switches console port via my laptop - not the most demanding use at a mere 9600 baud but very effective either way and very affordable.Happy to recommend.

I bought this USB to Serial adaptor to replace a lost adaptor and it works well.I use it to connect my laptop to Network device console ports via a USB port on my laptop.You just have to plug it in to your laptop and select the correct COM port on your terminal emulator.

I need these cables for my Cisco Switches and routers. I have a lab to keep my CCNP active. These network devices require a serial connection. Today's laptops don't have a serial natively so you need to use a DB-9 to USB cable or adapter.Once you connect, usually nothing happens in your computer. Here is what you need to do:- Open the device manager- Expand Ports (COM & LPT)- Note the COM port that was added when you plugged the cable.- On your serial connection software (Putty or similar), try to connect to that port number. Hit enter multiple times until the device displays a prompt or a welcome message.Work of caution: always save your open files when you use a serial port emulator. Some Windows have tendency to because instable and even crash depending on the motherboard and the drivers installed. So just save to avoid losing files.

Its a lead. It worked.

As has been mentioned in other reviews, this doesn't give negative voltage or particularly high voltage. This means that some devices just won't work with it, and it certainly isn't going to be good for longer distance comms where you get voltage drop over a longer cable run.So if it is for connecting to a small serial device on your desk it will probably work, but if the device is fairly old or on the end of a long serial cable then you'll find far better devices for that job at not much more cost.Widely supported chipset, so you'll be fine with most operating systems - but of limited use to me as mostly I'm interfacing with systems that need the full serial voltage range to work reliably.

The adapter converts between USB2 and RS232 via a single DB9 male adapter. The construction of the adapter is good and it feels robust. The logic is in the DB9 and of the cable.This device is based on the well known CH340 chipset. It works up to a 2MBPS baud rate. The output voltage is 0-5V (see scope traces, showing a 2Mbps output), there are no negative voltages. I'd expect a +5V / -5V output as this is the minimum for RS232, per the standard and documents such as the TI slla544, however I know that a number of devices are only positive with respect to ground, since this is a lot easier to generate and fairly common, even though it breaks the standard.Old serial devices may expect signalling of up to +/- 15V and therefore may fail to sense the far lower voltages produced by modern adapters such as this one.There were no drivers required and it just worked on Windows and Linux, since its plug and play, however drivers are available on-line if needed, search for the chip name CH340.Given its price and the functionality it provides, its good value for money.

Good value for money. Worked straight out of the box on MacI transferred a 179 MB file at 230400 baud, done a checksum on the file before and after and it was identical, so has a good reliable serial connection, even at high baudrate.

I needed this to use an older monitor with my laptop.Monitor only has a serial port, laptop doesn't have one.Does the job.Handy to have around for just this kind of problem.
