Then, you can connect your mouse and keyboard to the dedicated keyboard and mouse ports on the KVM.
-
Q: Does HDC403-P 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 can not be 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 keyboard and mouse dedicated 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, Cherry KC 1000SC(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: Does HDC403-P have a LAN port?
A: Yes, it does. HDC403-P has a built-in USB Ethernet Adapter, which adds a standard RJ45 port to all the PCs that are connected to the KVM and allows you to connect your computer to a router or network switch for a wired network connection without many network cables. Full 100Mbps Ethernet for fast, stable data transfer, more reliable than most wireless connections. Only one network cable can provide a wired network connection for your 4 PCs at the same time. The Network can be disabled or enabled in the KVM settings menu.
The LAN port on HDC403-P is solely designed for connecting network cables to enable all connected PCs to access the network. It does not support the use of control software to manage the KVM.
-
Q: How can I operate the front panel?
A: When you use the front panel button or IR remote to control the KVM, the LCD display will inquiry your target action, then execute the command according to your operation. The LCD interface in the figure above is the main interface.
-
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, and IR Remote Control.
