Frequently asked questions

What is the primary benefit of a 16-port RS232 card? It dramatically expands serial connectivity in a single PCIe card, reducing PCIe slot usage while enabling centralized management of many RS-232 devices such as terminals, sensors, and legacy equipment from a single host system.

What kind of devices can I connect? Any device that uses RS-232 with a DB9 connector can be connected, including industrial controllers, data loggers, medical instrumentation, cash registers, and point-of-sale systems. Each port operates independently to support simultaneous communications.

Which operating systems are supported? The card is designed for Windows and Linux environments, with drivers provided by StarTech. Always check the latest driver availability to ensure compatibility with your OS version.

Do I need extra power for this card? No. The card is bus-powered through the PCIe slot and does not require an additional external power connector.

How do I configure multiple COM ports? Once drivers are installed, your OS will enumerate each RS-232 port as a separate COM port (for example, COM1 through COM16 in Windows). You can then configure each port’s settings in your software or terminal program to match the connected device requirements.

Can I use all 16 ports simultaneously? Yes. The card is designed to support simultaneous data transfers across all 16 RS-232 ports, enabling parallel communication with multiple serial devices without bottlenecks.

Works well, long use on single charge, high torque - be careful when starting
Color: Black, Size: Rechargeable
Not the most inexpensive powered whisker bur I've used other Typhor products and found them reliable for the task designed. I fell they don't cheap out on the rechargeable battery so I don't fell they will catch fire, as we are hearing about from other cheaper rechargeable items. I liked 2 things about this model the speed control is by a pressure single switch which I can control, not just pick speed 1,2,3. The swappable tips allow for different uses. I don't drink coffee but use the item to whisk eggs for an omelets and it has the torque to mix them without effort. In Fact need to only use half power else it will splatter out of my mixing vessel.

I love this milk frother, a must have for coffee lovers!
Color: Silver
I absolutely love this Bonsenkitchen milk frother! It creates the perfect foam in seconds and my coffee has never tasted so good. The rechargeable feature is so convenient and I love that it comes with a stand to keep it organized on my counter. It is easy to use, easy to clean and works perfectly every single time. If you love coffee at home this frother is a game changer, it makes you feel like you are at a coffee shop without spending a fortune. Highly recommend!

Does the job!
Color: Silver
Great frother. Love that it's rechargeable. 3 speeds, double frothing ring. This one is way better than my last, battery operated one. A lot of people giving are negative reviews or deductin stars because they think you have to cycle through the speeds to turn it off - they're wrong. You just hold the button for a couple of seconds and it turns off. Highly recommend!

Stand was my favorite part, hated how close off and higher speed is
Color: Silver
Well the first lesson is dont hit the power button to turn off, as it goes to 2nd speed and slings your drink everywhere. Im not happy with the stability of the brother, had better, as free with coffees. Positive is, it has a stand, it does have 3 speeds, just never needed the other two speeds, and if you dont hold power button long enough to turn off, it goes into higher speed.
