Product Information
Full details
The Kramer EXT3-U-KIT is designed for professionals needing to extend USB 2.0, RS-232, and audio signals over long distances. Its key benefit is seamless connectivity up to 330 feet using a single Cat 6a cable, simplifying installations. A potential caveat is the reduced range to 98 feet when using Cat 5e cable.

FAQs
What is the maximum distance the EXT3-U-KIT can extend USB 2.0 signals?
The Kramer EXT3-U-KIT can extend USB 2.0 signals up to 330 feet (100 meters) over a Cat 6a Ethernet cable. The range is reduced to 98 feet (30 meters) when using Cat 5e cable.
Can I connect more than four USB devices?
The extender is designed to support up to four USB 2.0 peripheral devices connected to the transmitter.
Does the unit require any software installation?
No, the Kramer EXT3-U-KIT is a plug-and-play device and does not require any software installation for basic USB, RS-232, and audio extension.
How is the receiver unit powered?
The receiver unit is powered by an external power adapter. This provides optimal USB charging capabilities for connected peripherals. The transmitter can also power the receiver via the Ethernet cable, but with standard USB charging levels.
What types of USB devices are compatible?
It is compatible with a wide variety of USB 2.0 peripheral devices, including keyboards, mice, webcams, printers, scanners, smartphones, and external storage devices.
Can I extend USB 3.0 or higher speeds with this kit?
No, this kit is specifically designed for USB 2.0 signals. It does not support USB 3.0 or higher speeds.
What is the function of the RS-232 extension?
The bidirectional RS-232 extension allows for serial data transmission in both directions, enabling control of remote devices or data exchange between two serial ports separated by the Ethernet cable.
Troubleshooting
USB devices not detected
Ensure the Cat 6a/5e cable is securely connected at both ends. Verify that the receiver unit is powered. Try connecting fewer USB devices to check for power limitations. Test USB devices directly with the source computer to confirm they are functional.
Poor USB performance or intermittent connection
Check the length and quality of the Ethernet cable. Longer runs or lower quality cables (especially Cat 5e) can affect performance. Ensure the receiver is powered by its dedicated adapter for maximum USB charging current if peripherals require it.
RS-232 communication failure
Confirm that the RS-232 ports on both the transmitter and receiver are correctly wired according to serial communication standards. Verify the baud rate, data bits, and parity settings match on both ends and on the connected devices.
No audio output
Ensure the audio source is connected correctly to the transmitter's audio input and the playback device is connected to the receiver's audio output. Check audio levels on both the source and playback devices.
Status LEDs are off
Verify that both the transmitter and receiver units are receiving power. Check the power adapter connection to the receiver and the power outlet.
