What is the maximum transmission distance of the HDMI KVM Extender?
The kvm extender supports point-to-point extension up to 120 meters (394 feet) over a single Cat5e/6 network cable. It can also be routed through Gigabit network switches for flexible network deployment in point-to-multipoint configurations, allowing the signal to reach even further across a managed LAN.
What video resolution does the 4K HDMI KVM Extender support?
This device supports 4K Ultra HD resolution up to 3840x2160@30Hz and is fully backward compatible with lower resolutions (1080p, 1080i, 720p, etc.). It complies with HDMI 1.4 and HDCP 1.4 standards, with a pixel bandwidth of 225MHz and HDMI interface bandwidth of 5.97Gbps.
Does this KVM extender introduce any latency?
No. The extender uses high-speed ASIC (Application-Specific Integrated Circuit) technology to ensure near-zero latency for remote imagery, keyboard, and mouse operations. This makes it suitable for real-time applications such as live broadcasting, control rooms, medical imaging, and interactive KVM workflows where any perceptible delay would be unacceptable.
Can the KVM extender support USB devices besides keyboard and mouse?
Yes. The system features USB 2.0 ports (USB-A interface) that support a wide range of external devices including keyboards, mice, USB flash drives, printers, scanners, and other USB 2.0 compliant peripherals. This enables true workstation extension beyond just video and basic input.
What control signals does the HDMI over IP extender support?
It supports bidirectional RS232 control via a DB9 interface, with a fixed baud rate of 9600bps (other baud rates configurable on request) and 8-bit data bits. The system also supports EDID management and is compatible with HDMI 1.4 and HDCP 1.4. The RS232 channel is ideal for controlling projectors, AV processors, and automation systems at the remote end.
Is this KVM extender plug-and-play or does it require software configuration?
The extender is fully plug-and-play with zero configuration required. Simply connect the Transmitter (TX) to the source PC and the Receiver (RX) to the remote display and peripherals, then link them via Cat5e/6 cable. DIP switch pairing selects point-to-point or point-to-multipoint mode without any software setup or driver installation.
Does ORIVISION offer OEM and wholesale pricing for the ZY-CKH543?
Yes. As the original manufacturer of this KVM extender, ORIVISION provides OEM customization, bulk wholesale pricing, and B2B supply for system integrators, distributors, and AV professionals. We support custom branding, packaging, and firmware configurations. Contact info@orivision.cn for volume pricing and customization options.
Can I power on/off the remote PC from the receiver end?
Yes. The receiver (RX) unit includes a "PC PWR" button that allows you to remotely power on or power off the source PC connected to the transmitter (TX). This eliminates the need to physically access the host computer, which is especially useful when the PC is located in a locked server room or equipment cabinet.
