Customer questions & answers

Question: Does anyone know where to get the driver for a Mac?

I am sorry, the website may be not allowed here. This DTECH cable used Prolific chip, so, you can download the driver for Mac on Prolific's office website.
(Please search "prolific" on google and visit the office website, click Product Application > Smart I/O > USB to UAPT/Serial/Printer; and then click "PL2303 Mac OS X Driver Download") 

Question: What cord works best for converting usb to serial to connect an external monitor to a laptop?

Answer: This wouldn’t be what you’d want to go from a laptop to a monitor. Most laptops have a external monitor connection of some type. If you have to use USB they do make adapters. Try looking for a “usb to vga adapter”. Assuming you’re needing the VGA type connector. 

Question: has anybody used this serial cable for cisco switches?

Answer: no


Customer Feedback

1. I have several linux servers with DB9 male serial ports that I needed to monitor the serial console on. Using this serial adapter cable I was able to plug this into the DB9 connector and into a USB port on another linux box. Now I can easily login via serial console or log linux console activity in case of crash on the 2nd box.

2. I need to reset my cash registered and this cable just work very well for the programming task. I’m satisfy with the length, quality and durability of this product. I came along with a cd driver. Please double check, this is a female rs232 to usb. Make you pick the right cable (male or male).

3. Bought this USB 2.0 to RS232 DB9 Serial Cable Male A Converter Adapter with PL2303 Chipset for Windows 10, 8.1, 8, 7, Vista, XP, 2000, Linux and Mac OS X 10.6 and Above (3.3ft)
They both works great. This cable has nice shielding and thick wire.
Both are plug-n-play with genuine Prolific chipset recognized by Windows 7.

4. Installed on Windows 10 x64 10.0.17763.316 - was able to talk to the serial port of my router.
When I plugged it in Windows didn't automatically install the driver but when I pulled up Device Manger and selected "Update Driver" and allowed it to search online it was able to find and install the driver. Without rebooting I had COM3 and PuTTY was able to use it.

5. I went through many "prolific" clones that just didn't work before I came across this cable. It worked out of the box on Windows 10 with no fuss.
For reference, I used this cable along with a gender changer to program a device over serial interface using telnet. It worked perfectly.
