Installation Installation Overview To install and set up the SW USB switcher, 1 Mount the switcher on a rack shelf or under furniture, if desired. (See “Mounting the SW USB Series Switcher”, below.) 2 Connect host device(s) to one or more SW USB input connectors, using USB cable lengths of up to 15 inches (4.5 m) and USB B connectors. 3 Connect one or more peripheral USB devices to the SW USB Output Hub ports, using USB cable lengths of up to 15 inches (4.5 m) and USB A connectors.
Mounting the SW USB Series Switcher The SW USB Series switcher can be set on a table, mounted on a rack shelf, or mounted under a desk, podium, or table. Tabletop use Four adhesive rubber feet are included with the SW USB switcher. For tabletop use, attach one foot at each corner on the bottom of the unit, and place the switcher in the desired location. Rack mounting • RSB 123 — 1U, 3.5" Deep VersaTools® Basic Rack Shelf (part #60-604-20) • RSF 123 — 1U, 3.
Installation, cont’d Rack mounting procedure 1. If feet were previously attached to the bottom of the switcher, remove them. 2. Mount the SW USB Series switcher on the rack shelf, using two 4-40 x 3/16 inch screws in opposite (diagonal) corners to secure the unit to the shelf (seeHalfRackVersaToolsShelf the illustrations on the next page). 3. Install blank panel(s) or other unit(s) on the rack shelf as desired. 4. Install the shelf in the rack.
Furniture mounting 1. If rubber feet were previously attached to the bottom of the unit, remove them. 2. Remove the two screws from one side of the SW USB. Retain the screws for possible later reassembly. 3. Attach the brackets to the sides of the unit, using the provided machine screws. (See the illustration below.) 4. Hold the unit with the attached brackets against the underside of the table or other furniture. On the mounting surface, mark the location of the brackets’ screw holes. 5.

d RS-232 Pass Thru port — If desired, connect an Extron A/V switcher to this 3-pole, 3.5 mm connector (see “RS-232 Pass Thru port”, later in this chapter). Commands issued via the front panel, contact closure, or an RS-232 interface on a PC or control system can be sent through this port to the connected switcher. N Only Extron products can be controlled via this port.
Installation, cont’d Wiring the Power Connector If using a different external power supply from the one provided with the SW USB, you may need to wire the connector for it. To wire the power connector, 1. Cut the power supply’s DC output cord to the length needed. 2. Strip the jacket to expose 3/16 inch (5 mm) of the conductors. C Exposing more than 3/16 inch (5 mm) of the copper wires could allow the stripped wires to touch each other, causing a short circuit.
Wiring for RS-232 Communication RS-232 port The 3-pole, 3.5 mm captive screw connector labeled “RS-232” is used for optional RS-232 communication between the SW USB and a PC or control system. The control system plugged into this port can issue commands to the SW USB, which can pass the commands through to an Extron A/V switcher that is plugged into the RS-232 Pass Thru port. N Your RS-232 computer or control system should not be one of the host devices that are being switched.
Installation, cont’d RS-232 Pass Thru port The RS-232 Pass Thru port loops the signal received at the switcher’s RS-232 control port, the Contact (closure) port, or the front panel input buttons through the RS-232 Pass Thru port to send SIS commands to another Extron A/V switcher. N Only Extron products can be controlled via this port.
Contact Closure Control Contact closure is another method of input selection. To enable input selection by contact closure, you can connect a push-button contact closure device (such as an Extron CCR 2BLB, CCR 4BLB, or CCR 204) to the SW USB’s Contact port. Alternatively, you can manually short one of the pins to ground (the ground [_] pin is pin 3 for SW2 and pin 5 for SW4 models). Pin 1 selects input 1, pin 2 selects input 2, and so forth.
Installation, cont’d Connecting Multiple SW USBs in a System The USB specification states that a maximum of five hubs can be connected in a series; therefore, no more than five SW USBs can be cascaded in a series. N Do not exceed five cascaded hubs and a total of 127 peripheral devices in the entire system.

2. Plug the power supply into the two-pole captive screw power connector on the rear panel. The unit performs a self-test, during which the Exec Mode LED and the front panel Input LEDs each blink once in sequence from left to right. If the selftest completes with no errors, the LED for the most recently selected input remains lit. 3. Select input 1 and power up the PC connected to it. 4. Select each desired remaining input and power up the PC connected to it.
Operation, cont’d Issuing commands to an Extron A/V switcher via the RS-232 Pass Thru port To configure the SW USB to pass commands through the RS-232 Pass Thru port to a connected A/V switcher, you must select a loop mode. The loop mode determines which types of commands are passed through this port. The two loop modes are: • Loop 1 mode — In this mode, SIS commands sent to the SW USB via an RS-232 interface are passed through the RS-232 Pass Thru port to the A/V switcher.
SIS Command SW USB function SW USB response to host ! Performed and passed through Chn X! ] ^ Performed, not passed through Usb X! ] E (any) Performed, not passed through See the SIS command table. X Performed, not passed through X# ] N Performed, not passed through 60-95n-01 ] Q Performed, not passed through n.nn ] *Q Performed, not passed through n.nn.

Select input 1 Pin 2 to _ 2! Select input 2 Pin 3 to _ 3! Select input 3 Pin 4 to _ 4! Select input 4 Enabling front panel lockout (executive mode) Executive mode disables all front panel controls, locking out the user from those functions.
Setting up for host emulation To enable host emulation, 1. Connect a keyboard, a mouse, or both to output port 3, 4, or both. The SW4 USB Plus can emulate a keyboard and a mouse simultaneously. Either type of device can be connected to either or both of the two emulation ports (3 and 4). N The SW USB cannot emulate a host through ports 3 and 4 if a hub or an extender with an internal hub is connected to either of these ports.
Operation, cont’d Troubleshooting If the SW USB detects a non-standard keyboard or mouse, an error condition may occur in which the Exec Mode LED blinks and the SW USB reboots in a repeating cycle. If this happens, and rebooting does not resolve the issue, set the host emulation DIP switch(es) to Off, and then wait for the switcher to reboot. You will not be able to use host emulation with that keyboard or mouse.
6. In Windows Explorer or another file browser, locate the downloaded executable installer file and double-click it to open it. 7. Follow the instructions on the Installation Wizard screens to install the Firmware Loader on your computer. Unless you specify otherwise, the installer program places the Firmware Loader file, “FWLoader.exe”, at c:\Program Files\Extron\FWLoader. Downloading and installing the SW USB firmware 1. Go to the Extron Web site at www.extron.com and click the Download tab. 2.
Operation, cont’d Loading the firmware to the SW USB using the Firmware Loader To load a new version of firmware from your computer to your SW USB using the Extron Firmware Loader software, your computer’s serial port must be connected to the switcher’s RS-232 serial port.
