Installation
Verify that the distance between the USB transmitter and receiver are within
MuxLab specifications (150 ft / 46m).
Host-Side Installation
Install the host-side transmitter as follows:
1. Connect the Host side transmitter to the computer’s USB port.
2. Connect a Cat5e (or higher) grade UTP cable to the RJ-45 connector on
Transmitter.
Device-Side Installation
Install the device-side receiver as follows:
1. Connect the Receiver to the USB Peripherals with USB-compliant cables.
2. Connect the Cat5e cable to the RJ-45 connector of the Receiver. If the
computer is powered on, the “Link” LED will be ON.
3. Connect the 5 VDC power supply first to the Receiver and then plug the
power supply into an AC power outlet (mains plug). If power is available,
the green power LED will be ON.
In some cases, power from the PC’s USB port may be sufficient to run up
to four self-powered USB devices or one or two low-power USB devices
such as a mouse and a keyboard. However, we recommend that you always
connect the power supply included with the kit to the receiver for best
performance.
The following diagram shows the final configuration.
