Introduction This section provides an overview of the guide and the product. The following topics are discussed: • About this Guide • About the USB Extender Plus T/R • Features About this Guide This user guide contains information to install, configure, and operate the Extron USB Extender Plus T/R transmitter and receiver pair. Additional product information can be found on the Extron Electronics website at www.extron.com.
• Asynchronous transfers — Supports USB devices that require asynchronous transfers. • Real-time status LED indicators for troubleshooting and monitoring — Front and rear panel LED indicators provide visual confirmation of port activity between an active host and each connected peripheral device. • Rack and furniture mountable — Low-profile, 1-inch (2.5 cm) high, quarter rack wide metal enclosures enable the extenders to be installed discreetly, such as beneath a table or inside a lectern.
Installation and Operation This section provides the following details: • Connection Guidelines • Rear Panel Connections • Cabling and Setup • Front Panel Features • System Operation • Troubleshooting Connection Guidelines The USB Extender Plus T/R can be installed in existing and new systems within the following guidelines: • USB extenders cannot be cascaded (you cannot sequentially connect a USB Extender Plus T/R to another USB Extender Plus T/R or to a FOX T/R USB Extender Plus).
A Power connector — Connect a provided 12 VDC, 1 A max. external power supply to this 2-pole, 3.5 mm captive screw connector. ATTENTION: • The power supply must not be permanently fixed to the building structure or similar structures. • La source d’alimentation ne devra pas être fixée de façon permanente à une structure de bâtiment ou à une structure similaire. • Do not place the power supply within environmental air handling spaces or the wall cavity.

Important: Do not connect power to this port until you have read the Attention notices on the previous page.
Installation Overview ATTENTION: • Installation and service must be performed by authorized personnel only. • L’installation et l’entretien doivent être effectués par le personnel autorisé uniquement. To ensure proper operation, the transmitter, receiver, USB host, and USB peripherals must be connected properly and in the sequence described below (see figure 4 on the previous page). 1.
Pairing the Transmitter and Receiver In order to function together, the transmitter and receiver must be paired the first time they are used together. Both units must be connected together through their RJ-45 connectors (the transmitter Output connector and the receiver Input connector) and powered on. NOTES: • After they have been paired, the transmitter and receiver can be powered down and disconnected from each other. • A transmitter and receiver need to be paired only once (at startup).
Connecting for Serial Communication The front panel Config ports on both the transmitter and the receiver (see figure 6, C, on the next page and figure 7, C, on page 10) enable communication with a computer via an RS-232 connection. Connect a 9-pin D-to-2.5 mm cable from the computer serial port to the Config port on the transmitter or receiver front panel to enable serial communication.

Troubleshooting USB signals are generally reliable but are susceptible to bad connections or cables that are too long. The TP cable can have the same issues. To avoid the loss of data and communications, follow these guidelines: • The USB cables that connect the transmitter to the host or the receiver hub ports to peripheral devices should not exceed 6 feet (1.8 meters). • When connecting the host or peripherals, use only cable designed for USB signals. • Avoid or limit the use of adapters.
Remote Configuration and Control This section describes the connection through which the USB Extender Plus can be configured and controlled remotely via Simple Instruction Set (SIS) commands, and describes the commands that are available.
Error Responses If the extender is unable to execute a command it receives because the command is invalid or contains invalid parameters, the USB Extender Plus T-R returns an error response to the host.
