9. The (orange) Link LEDs will illuminate on both local transmitter and
remote receiver units to indicate a successful connection has been
made between the two units. The screen should now display on the
connected monitor.
USB/IR/RS-232 Controls
The extender kit provides the following functional controls:
• USB 1.1 – One Micro-USB input at transmitter, dual USB-A outputs at
receiver
• Bi-Directional IR–Dual 3.5 mm jacks at both the transmitter and
receiver
• RS-232 – One 3-pin phoenix connector at both the transmitter and
receiver
(Optional) Connect the computer's DB9 port to the transmitter unit's
RS-232 serial port. The serial port is a 3-position phoenix connector for
RS-232 (DB connector) pin 2, 3 and 7 connection. Connect your RS-232
device (e.g. barcode scanner) to the 3-position phoenix connector on the
receiver unit.
(Optional) Connect the included IR-OUT cable to the transmitter unit's
IR-OUT port. Place the sensor on the IR-OUT cable in an unobstructed
area within clear view of the device being controlled. Then connect the
included IR-IN cable to the receiver unit's IR-IN port. The IR-IN cable will
communicate the desired command via the transmitter's IR-OUT cable.
Note: The IR-OUT cable receives the signal from the remote control and sends
it to the device being controlled (e.g. Blu-ray™ player, etc.).
(Optional) With a user-supplied USB Micro-B cable (such as Tripp Lite
U050-XXX Series USB cable), connect to the transmitter's Micro-B port.
Then connect a keyboard and mouse to the available USB-A ports on the
receiver unit.
