Description
Add RS-232 DCE serial communications support to a desktop or laptop computer and resolve DCE/DTE conflicts directly without the need for additional cross-wired serial cables or adapters.
Serial Port Expansion
The 6.6-foot (2-meter) Null Modem USB Serial Adapter adds an RS-232 serial DB/DE-9 (female) connector to a desktop or laptop via a USB Type-A port. Secure the adapter to a serial device, using pre-installed and removable slotted D-Sub thumbscrews or install the included DB-9 Nuts for compatibility with other serial peripheral devices or cables.
LED Indicators
Data transmission and reception LED indicators on the adapter provide real-time monitoring of port activity. The USB LED indicates when the adapter has successfully enumerated on the desktop or laptop. All the LEDs aid with diagnostics and troubleshooting.
Seamless Connectivity
The adapter is compatible with Windows, macOS, ChromeOS, and Linux. Drivers automatically install to Windows 7 and newer versions, macOS 10.15 and above, and Linux. The USB to RS-232 adapter features COM retention, which automatically reassigns the COM port value if the cable is disconnected and reconnected, or if the system is rebooted.
Built To Last
The rugged TPE construction and Level-4 ESD protection (15kV air and 8kV contact) enhance the reliability and longevity of the USB to Serial Adapter. Copper shielding minimizes Electromagnetic and Radio Frequency Interference (EMI and RFI). Gold-plated connectors enhance signal conductivity.

Needed a fairly obscure part for part of the power cable on my laptop plug. Delighted to be able to get it from ValuPC. As always a simple process. Ordered and received 2 days later.

I have ordered a TV that I couldn't get anywhere else in Ireland and Valu PC had it. Delivery took 2 days and Jim was extremely nice and helpful with everything and even delivered it to me himself. I will definitely be ordering from him again.

Delivery arrived within a day - and it was Christmas week! Headphones were really competitively priced. Delighted with them. A hassle free online purchase. Very happy with my experience.

Wouldn't normally bother with review's but I was really impressed with ValuPC, despite never having heard of them before. While googling a specific laptop model I noticed that they're cheaper than other psychical stores by over €200. I ordered the laptop late one and 2 - 3 it was at my door. Excellent service fast and reliable and have already recommended to others.

Was going to go to an English chain of computer shop, googled and seen valupc. I ordered a new laptop and Monitor late Sunday night and had them in my hands on Wednesday morning with everything working as expected. I would recommend Valupc as they are Irish and defiantly good value, will be back in the future.

great deals on the market, which seemed sketchy, but decided to order a monitor anyway. Was delighted to know that I was wrong, The monitor came in perfect condition, nothing bad to say whatsoever. Even had some problems with the delivery and they helped me out! It's a great site to buy electronic things of off, don't think twice about it.

I was shopping laptops across multiple retailers mainly the typical big ones and went searching laptop sales and found VALU PC. Their laptop prices / specs etc were easily beating the rest so looked into it further.
I even spoke to the owner, had a great, friendly chat and found they were more local than i thought and he guarenteed me 2 days delivery to the door and that's what I got!
