Reviewed in the United States on March 9, 2024

Style: Female ScrewVerified Purchase

This USB/DB9 cable allowed me to hook-up my older Innova 3110 CanOBD2 to my laptop. Cable worked without using the included driver software disc. There is a 6 foot USB/DB25 cable available but at 3x the cost of this cable I can deal with the added length of cable with with a twist tie.

Close, but no cigar!

Reviewed in the United States on June 14, 2023

Style: Female ScrewVerified Purchase

Use with 2 laptops - one Windows 10, one Windows 11. I plugged the adapter into a USB port on each laptop in turn and each one recognized the adapter instantly. Going to Device Manager I found that the adapter appeared as COM3, 9600,8,N,1 on both machines. Was able to re-assign the port number to what I needed without any problem. I did not need the included CD to set up and use the device. HOWEVER when I went to plug the male end on the adapter into the female socket on the device I was connecting I discovered that the 9-pin RS-232 plug on the adapter has FEMALE screw sockets instead of male screws to attach it with. It was impossible to plug the adapter into the female receptacle on the device I was trying to connect. This is stupid. RS-232 has been around forever, and the MALE end should have the screw connectors and the FEMALE end have the screw sockets. I had to use an RS-232 extension cable in order to connect the adapter to the device.

Reviewed in the United States on February 18, 2024

We use this on our Pactor SSB/Ham modem. Rather than running a true serial connection (outputs on modern computers frequently don't have an RS232 connection) this allows us to use one of the very many USB ports available to us.

Ours is a marine environment; we like it.

Current version does not appear to work on Macbook Pro with M2 Silicon

Reviewed in the United States on July 9, 2023

Style: Male ScrewVerified Purchase

I have purchased these - they came with the PL-2303 chip inside and work just fine on my Mac, both M1 and M2. Also on my PC (windows 10).

However I purchased 1 recently and it is not recognized by my Mac (M2). It does work on my PC, but the mac won't recognize it. Downloading the newest drivers didn't change that.

From the Macs System Information/USB listing... the old, working version of this cable shows a Product ID of 0x2303, vendor Prolific. This new, non-working cable, shows up as Product ID 23a3, vendor = Prolific.

I'm guessing the product ID is not matching the driver for some reason. I've done some searching around the internet and haven't seen any references to this.... other than the general advice to get an FTDI chip cable and not use the 2303 cable.

The product information does not mention this issue - everything just says compatible with Mac.

Didn't work

Reviewed in the United States on September 26, 2022

Style: Male ScrewVerified Purchase

The description states that it's PL-2303 but doesn't interchange with my existing one. It reads but won't transmit. Pin 5 is connected to the USB module but Pin 9 isn't. Going to try another brand but I compared my existing cable to this one by pinout versus a USB connector but they don't match.

Excellent product it works perfectly

Reviewed in Canada on December 1, 2023

Style: Female ScrewVerified Purchase

Whoever says it does not work, they are probably not capable to install some Windows drivers, or just stupid. I've seen so many bad reviews from other people, just bla bla bla... But the cable is very high quality. I didn't try it yet on MACOS but I see that it has as well all the necessary drivers.
The drivers for Windows are real Prolific drivers so it's using the Prolific chipset.
