Q: How should I connect my keyboard and mouse?
A: Inside the package, you will find four USB-A to USB-B cables. The USB-A to USB-B cable is connected to transfer USB data between the computer and the KVM, which enables the keyboard and mouse to control computers normally. Simply connect the USB A end of the cables to their respective computers and insert the USB B end into the KVM. Then, you can connect your mouse and keyboard to the dedicated keyboard and mouse ports on the KVM.
Q: Does PKS0802A10 support Bluetooth keyboard and mouse?
A: This model does not support Bluetooth keyboard and mouse, and all our KVMs do not support Bluetooth keyboard and mouse, but they all support 2.4GHz wireless keyboard and mouse and are compatible with a wide range of mechanical keyboards and mice, wireless keyboards and mice, and multimedia keyboards and mice.
Q: Can I use the keyboard and mouse on multiple computers simultaneously?
A: Our KVMs are used to share a set of keyboard and mouse between multiple computers, and the keyboard and mouse are not used between the multiple computers at the same time, but the sharing of keyboard and mouse is achieved by switching input devices. In display mode 2 (2 monitors display the different PCs), you can double-click [Right-Alt] to switch the focus of the keyboard and mouse. This way, you can control both computers without the need to physically disconnect and reconnect the peripherals each time you want to switch between them.
Q: What keyboards are compatible with your KVM?
A: Our KVM is compatible with most keyboards. Considering our KVM's dedicated keyboard and mouse ports are equipped with special hotkey chips, there are some typical reasons that may cause compatibility issues:
1. Some keyboard models use proprietary protocols that are temporarily incompatible with the dedicated ports on our KVM.
2. Certain keyboard models, when plugged into the dedicated ports on the KVM, consume excessive bandwidth, leading to compatibility issues such as keyboard lag or key sticking.
To address these compatibility issues, we recommend customers connect keyboards that encounter problems when plugged into the keyboard and mouse dedicated ports on the KVM to the USB 2.0/USB 3.0 ports on the KVM. The USB 2.0/USB 3.0 ports do not have the built-in special chips found in the dedicated keyboard and mouse ports. Plugging your keyboard into the USB 2.0/USB 3.0 ports effectively treats it as if it were directly connected to the computer.
Due to the wide variety of keyboard models available in the market, our R&D department cannot conduct compatibility tests on every keyboard. Below are some keyboard models that have been reported as incompatible by customers: Dell KB813 (and similar keyboards with a card slot), Logitech MX series (some of which cannot manually switch between Windows and macOS modes), Roccat, and certain Microsoft keyboard models.
You can also refer to keyboard and mouse models that have been tested and approved by our R&D department:
Q: What is Auto Scan Mode and how to use it?
A: The Auto Scan feature can automatically switch the display at regular intervals between the input devices that are powered on and connected to the KVM. As a result, any input devices connected to each port can be monitored without user intervention. Auto scan mode is off by default. You can turn on the auto scan mode through the front panel button, keyboard hotkey, infrared remote control, RS232, etc.
The LED named "Status" on the front panel will be lit in different colors when the auto scan mode is turned on or turned off.

Q: I have a Dell XPS 15 9530 with a Dell Thunderbolt Dock WD22TB4, an HP Elite Desk (DTPC-HP-800-G4-i7), and two Dell U2422H monitors. I think these monitors allow daisy chains via DP cable. Your help is appreciated to enable me to make the correct purchase of KVM.
A: Based on your situation, our PKS0802A10 KVM is suitable for you. The PKS0802A10 can connect 4 PCs and 2 monitors with pure DP ports.
It is important to note that each computer will require 2 DP ports and 1 USB-A port and each monitor will require 1 DP port when connecting PKS0802A10. If your device lacks sufficient ports, you may need to purchase additional conversion cables and docking stations. Our package includes all the necessary cables required for the computer end. Any additional cables or conversion cables will need to be purchased separately.
To assist you in selecting the appropriate cables for specific devices, you can check the reference list below:
1. Dell XPS 15 9530: use a USB-C cable to connect the dock to it, then use two DP cables and one USB-A to USB-B cable to connect the dock to the KVM
2. HP Elite Desk: two DP cables; one USB-A to USB-B cable
3. 2x Dell U2422H monitors: one DP cable EACH
Regarding whether the converter will affect the resolution, generally speaking, it should not impact the resolution. However, if there is an incompatibility issue between the converter and our device, it may cause video signal transmission issues such as flickering, black screen, or reduced resolution. We cannot guarantee it completely.
