3.2.4 USB Connection
Figure 7 – USB Port
The USB port on the extender can be used to update the device firmware via a
Windows GUI and to set the power saving mode if no RS-232 or IR are used.
Please download the GUI software user guide for further information.
3.2.5 IR Connections
The extender can extend Infra-red Remote Control signals in both directions. It
has one IR input connector for an optional IR detector cable, and 8 IR output
connectors for optional IR emitter cables.
To provide maximum compatibility, IR signals are passed with their
modulation frequency intact.
IR Signal from the UHBX-8X to compatible receivers
Figure 8 – IR Input
The UHBX-8X can generate IR signals by itself based on Telnet or RS232
commands. The generated IR signal can also be directed to any one or
combination of outputs using simple ASCII control commands (see section 4
for further details).
Additionally, if an IR detector cable is plugged in to the IR input of the
UHBX-8X, then this signal is also extended to the addressed receivers. In this
way the user can use a TV’s remote and point it at the IR detector that is
plugged in to the UHBX-8X and be able to control the remotely located TV.
