Frequently Asked Questions - KVXLC-100 Black Box

What is the maximum distance supported by the KVXLC-100 over CATx cable?

The KVXLC-100 supports extension up to 330 feet (100 meters) over standard CATx cable.

Can I use this extender with VGA monitors?

Yes, the DVI-I ports accept DVI or VGA signals using appropriate adapters or cables. The extender supports video resolutions up to 1920 x 1200 @ 60 Hz.

How do I connect USB peripherals?

Connect the transmitter's USB Type B port to your computer. The receiver provides 2 USB 2.0 Type A ports for devices and 2 dedicated USB HID ports for keyboard and mouse.

What type of cable is required for connection?

Use CATx cable (EIA/TIA 568B compliant) for up to 100 m. For longer distances, consider the fiber models (KVXLCF-100) which support up to 30 km with approved SFPs.

Can I extend RS-232 serial signals?

Yes, the extender supports bi-directional RS-232 communication. Connect the serial device to the DB9 connector on the receiver (front panel for single-head, rear for dual-head). Default baud rate is 115,200 bps, 8 data bits, no parity, 1 stop bit.

Does the extender support audio?

Yes, it provides 2-way analog audio extension. The transmitter has line-in and line-out jacks; the receiver has mic-in and speaker-out jacks.

What power supply is required?

The extender uses an external 5-VDC, 2-A power supply (included with US, EU, and UK plugs). Both the transmitter and receiver need power.

How do I reset to factory defaults?

Factory default settings are: baud rate 115,200 bps, 8 data bits, no parity, 1 stop bit. There is no user reset button; restore defaults by cycling power or using the configuration software.

Is the extender compatible with all operating systems?

Yes, the KVXLC-100 is OS independent and works with Windows, macOS, Linux, and other platforms without additional drivers.

What should I do if there is no video output?

Check that all cables are firmly connected. Ensure the display's input source is set to DVI. Verify the computer's BIOS video output settings. Test the video source directly to isolate the issue. If problem persists, contact Black Box technical support at 1.877.877.2269.

Follow these steps to install the extender:

1. If you have the fiber models, install the SFPs in the transmitter and receiver. Compatible SFPs from Black Box are listed in the table below.

COMPATIBLE SFP MODULES

PART NUMBER DESCRIPTION DISTANCE
1-GBPS CONNECTIONS
LFP441 SFP 1.25-Gb, 850-nm Multimode Fiber, LC 550 m
LFP442 SFP 1.25-Gb, 1310-nm Single-mode Fiber, LC 20 km
LFP412	SFP with Extended Diagnostics - 1250-Mbps Multimode Fiber, 1310-nm	2 km
LFP413	SFP with Extended Diagnostics - 1250-Mbps Single-Mode Fiber, 1310-nm	10 km
LFP414	SFP with Extended Diagnostics - 1250-Mbps, Singlemode Fiber, 1310-nm	30 km
LFP416	SFP 1250-Mbps, Extended Diagnostics, 10/100/1000BASE-T, SGMII Interface, RJ-45	100 m

NOTE: Other SFPs may work but have not been validated by Black Box, we recommend you use the suggested SFPs to avoid technical incompatibilities.

NOTE: SFP is not included, must be ordered separately.

1. Connect the video source(s) to the Transmitter (Computer Unit).
2. Connect the monitor(s) to the Receiver unit.
3. Use CATx cables (EIA/TIA 568B industry standard compliant) or fiber cables for connection between Transmitter/Receiver.
4. Apply the proper power to all connecting devices.

NOTES:

a. We recommend using the highest quality materials (cables, SFP, etc.) to ensure optimal transmission quality.
b. If the screen does not display when you connect the computer:

1. Make sure the device cables are correctly and firmly attached.
2. Set your display device's (TV, monitor, etc.) input source as DVI.
3. Check the PC BIOS configuration of the video output setting.
4. Connect your video source to the Display DIRECTLY to check if the video signal gets through.
