Supported Peripheral Devices; Troubleshooting; Peripheral Emulation (Sw4 Usb Plus Only); Updating Firmware - Extron electronics SW2 USB User Manual

NOTES:

Supported peripheral devices

The SW4 USB Plus can emulate a host only to a standard keyboard and a standard mouse.
The emulation feature is not supported with non-standard keyboards or mice, such as
devices that require additional drivers.
For example, the SW USB does not support host emulation for RF/Bluetooth keyboards and
mice, hubs, extenders with internal hubs, or any peripherals connected to those types of
devices. If these devices are connected to output ports 3 and 4 when the DIP switches are
set to On, the devices are switched through to the input.
Alternatively, you can set the Host Emulation DIP switches to Off when using these devices.

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 switches to
Off, and then wait for the switcher to reboot. You will not be able to use host emulation
with that keyboard or mouse.

Peripheral Emulation (SW4 USB Plus Only)

In addition, the SW4 USB Plus emulates a mouse and keyboard to the computer or other
input device that is connected to the selected input port. This emulation of peripheral
devices is constant, whether or not a keyboard or mouse is actually connected to the ports,
facilitating problem-free boot-up. Keyboard and mouse emulation is always present on the
inputs of the switcher.

Updating Firmware

Extron periodically updates product firmware in conjunction with the release of new
software revisions. Before updating any Extron product to the latest revision level, be sure
to read the supplied release notes or contact Extron Technical Support to determine if your
product requires a firmware update.
You can find out what version of firmware is currently loaded on your switcher by entering
the SIS
the "SIS Programming and Control" section).
• If two mice or two keyboards are connected to output ports 3 and 4, and the
appropriate emulation DIP switch is set to On, the switcher emulates a host to
only one port.
• When one or both DIP switches are set to On (up), host emulation follows the
attached peripheral device:
When the Mouse DIP switch (switch 1) is set to On (up), the switcher
•
emulates a host to any standard mouse that is connected to either of the
emulation output ports (3 or 4).
When the Keyboard DIP switch (switch 2) is set to On, the switcher emulates
•
a host to any standard keyboard that is connected to an emulation port.
When both DIP switches are set to On, the switcher emulates a host to any
•
connected standard mouse or keyboard that is connected to port 3 or 4.
