How to Install Black Box KVM Switch - 4-Port

• Step 1 — Gather your cabling: Prepare a VGA video cable for each PC and the monitor, plus PS/2 keyboard and PS/2 mouse cables. If your keyboards or mice use USB, you’ll need adapters or a model that supports USB-to-PS/2 passthrough, depending on the exact switch configuration.

• Step 3 — connect the display and peripherals: Attach the monitor’s VGA input to the KVM’s output port. Ensure the keyboard and mouse are firmly connected to the PS/2 ports on the switch. If a separate power supply is required by your model, connect it now.
• Step 4 — power on and test: Power on the switch (if applicable) and then boot the connected computers. Use the front-panel buttons or the configured hotkeys to switch between machines. Confirm that the monitor, keyboard, and mouse respond correctly for each connected PC.
• Step 5 — adjust as needed: If you encounter display or input issues, verify cable integrity, re-seat connections, and ensure the PCs’ video resolutions align with the monitor’s supported range. For best results, keep monitor and PC video settings within standard VGA ranges.
