CKS202-P23 (Previously CKS0202A1U) FAQ

Pre-sales FAQ:

  1. Q: How do I connect my devices to the CKS202-P23?

A: The input ports of the CKS0202-P23 are the USB-C ports and the output ports are the HDMI ports. There are four USB-C cables in the product packaging. When connecting your devices to KVM, each computer should be connected to KVM using one USB-C cable or two USB-C cables. Each monitor should be connected to KVM using an HDMI cable.

Connect PC 1 and PC 2 in different cases as follows:

①: If your PCs are running Windows OS:
Connect 2 PCs to the Input ports marked "A" of each input group of the KVM with 2 USB-C cables individually to enable the MST mode. Connect 2 PCs to the Input "A" & "B" or only Input ports marked "B" of each input group to disable the MST mode(As shown below).
②: If your Type-C laptops are running MacOS: Connect 2 laptops to the Input "A" & "B" ports of each input group of the KVM with 4 USB-C cable.

Connect KVM's HDMI output ports to 2 HDMI monitors with 2 HDMI cables:

  1. Q: What is MST Mode?

A: The traditional dual monitor KVM switch needs to connect two cables to each input device for the normal use of the dual monitor function. But our USB-C dual monitor KVM Switch, CKS0202-P23 supports Multi-Stream Transport(MST) mode allowing dual HDMI displays from a single USB-C source.
If your Windows OS PC with USB-C port and is DisplayPort 1.2 compliant, you can adopt two console monitors from it by connecting one single USB-C cable according to the pictures below, the display mode will enable MST mode automatically.
Tips: Up to now, devices running Apple’s Mac OS, Ubuntu, and other operating systems do not support MST mode. This means that those devices need to be connected to the KVM by using two USB-C cable.
  1. Q: How many display modes are available for CKS202-P23?

A: The CKS0202-P23 KVM offers 2 display modes. You can choose to implement 2-screen extended display or duplicate display or display different PCs on 2 monitors.
  • Display Mode 1: Display the same PC:
  • Display Mode 2: Display the different PCs:

  1. Q: How should I connect my keyboard and mouse?

A: Inside the packaging, you will find four USB-C cables. Using the USB-C cables to connect your computer to the KVM not only transmits audio and video signals but also facilitates the transfer of USB data, enabling proper control of your computer using the keyboard and mouse. Once you have connected the USB-C cables, you can further connect your keyboard and mouse to the dedicated keyboard and mouse ports on the KVM.
  1. Q: Can I use the keyboard and mouse on two computers simultaneously?

A: Our KVMs are used to share a set of keyboard and mouse between two computers, and the keyboard and mouse are not used between the two 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.
  1. Q: Does CKS202-P23 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.
  1. Q: Can the USB 3.0 port on the front panel charge my computer? If not, can the KVM charge my computer?

A: The USB 3.0 port on the front panel supports charging functionality with a maximum output power of 7.5W. So, it is designed to charge mobile phones or tablets and is not suitable for charging laptops or computers.
However, connect the laptops to the rear Type-C video ports of the KVM and they will be charged. Please be aware that only by connecting the device to the port marked "A" can it be charged. When the laptop is connected to both the KVM and the original charger, the charger will give priority to charging it. Additionally, the USB-C port on the laptop needs to support the charging protocol to be able to charge.
  1. Q: Does CKS202-P23 support audio and USB locking?

A: The CKS0202-P23 does not support locking audio and USB focus. However, you can switch separately audio focus and USB focus using a set of hotkeys as follows:
To switch the USB 3.0 device connected to the KVM between 2 PCs in display mode 2, use the following hotkey combination: [Right-Ctrl]→[Right-Ctrl]→[↑]
To switch the audio focus between 2 PCs, use the following hotkey combination: [Right-Ctrl]→[Right-Ctrl]→[↓]
  1. Q: Does CKS202-P23 have a LAN port?

A: Yes, it does. CKS0202-P23 has a built-in USB Ethernet Adapter, which adds a standard RJ45 port to your Ultrabook and notebook that is connected to the KVM and allows you to connect your computer or tablet to a router or network switch for wired network connection. 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 2 PCs at the same time.
The LAN port on CKS0202-P23 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 control and manage the KVM.
  1. Q: How do I switch the input sources via the buttons on the front panel?

A:
  • Press [Select] button to switch between PCs on display mode.
  • Press [A]/[B] button to switch between PCs on the corresponding monitor on display mode.
  • The indicator lights blue means the current PC’s main desktop is displayed on the marked monitor, it lights green means the current PC’s subordinate desktop is displayed on the marked monitor. For example, press [A] until you see the 1 LED is lit blue, which means you have selected PC1 Input A as input for Display A; press [B] until you see the 2 LED is lit green, which means you have selected PC2 Input B as input for Display B.
  • When switching individually, the default channel selection sequence is PC1 Input A - PC1 Input B - PC2 Input A - PC2 Input B. If one of the monitors has already determined the display channel, the channel selection of the other monitor will automatically skip the channel displayed by the previous monitor. For example, when Display A displays PC1 InputA, the PC1 InputA port displayed by DisplayA will be skipped when DisplayB is switched.
  1. Q: How to switch the input source?

A: There are three methods to switch the input source: the front panel button, keyboard hotkey, and infrared remote control.

The front panel button:

Press [Select] button to switch between PCs on display mode 1.
Press [A]/[B] button to switch between PCs on the corresponding monitor on display mode 2. (The "A" and "B" buttons on the front panel, as well as the "⬅" and "➡" keys used with hotkeys, are specifically designed for switching between video output channels.)

Keyboard hotkey:

Select previous input port: [Right-Ctrl]→[Right-Ctrl]→[PgUp]
Select next input port: [Right-Ctrl]→[Right-Ctrl]→[PgDn]
Select port by port number(i.e. the display mode 1): [Right-Ctrl]→[Right-Ctrl]→[1]~[4]
Switch to display mode 2:
Think of display A as the main display, switch images on display B::[Right-Ctrl] → [Right-Ctrl] → [→]
Think of display B as the main display, switch images on display A::[Right-Ctrl] → [Right-Ctrl] → [←] Switch USB 3.0 device connected to the KVM between 2 PCs on display mode 2: [Right-Ctrl]→[Right-Ctrl]→[↑]
Switch audio focus between 2 PCs: [Right-Ctrl]→[Right-Ctrl]→[↓]
Switch KVM focus in display mode 2: [Right-Alt]→[Right-Alt]

  1. Q: Does CKS202-P23 support G-Sync?

A: About the G-Sync, it needs HDMI 2.1 or DP 1.2, G-Sync HDR needs DP 1.4, but now display manufacturers HDMI 2.0 can also pass G-Sync certification, so whether G-Sync is supported depends on whether your input device supports it.
It needs to be noted that:
① First of all, your input and output source device needs to support G-Sync.
② Our KVM will not make any modification to your video signal (data pass-through)
③ Our USB 3.0 HDMI KVM Switch supports the HDMI 2.0 protocol. The maximum bandwidth is 18gbps. Using G-Sync will cause a certain instantaneous bandwidth increase.
Therefore, when you use this function, you must pay attention to bandwidth issues. Please be careful not to exceed the maximum bandwidth limit.

  1. 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 2.0/3.0 ports on the KVM. The USB 2.0/3.0 ports do not have the built-in special chips found in the dedicated keyboard and mouse ports. Plugging your keyboard into the USB 2.0/3.0 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:
  1. Q: What is the recommended operating temperature for your product?

A: The CKS0202-P23 is designed to operate within a temperature range of 0 to 50 degrees Celsius. Please note that our products fall under the category of consumer electronics and are not industrial-grade equipment.
  1. Q: Is it safe to use your KVM?

A: Yes, it is. Our KVM falls under the category of physical KVMs. It is designed specifically for switching and transmission of audio, video, and USB data. One remarkable aspect of our KVM system is that it functions independently of internet connectivity; it simply requires a power connection to operate.
Our KVM employs a direct data transmission mode, ensuring that no alterations are made to the transferred data during the process. Furthermore, it is important to note that the KVM does not possess any storage functionality, alleviating any concerns about potential data leaks. Essentially, our KVM serves as a dedicated device that not only ensures an absence of data exchange between connected hosts but also facilitates the shared use of a single set of keyboard, mouse, and display between two host systems, all achieved through a physically isolated switching mechanism.
