8.5 Operational Notes
• Battery
- When the USB port is set to RS-232 mode some power is also provided
to the unit via USB, however a properly charged battery is still required
to operate the unit.
- Many USB hubs do not provide proper 5V power to connected devices.
When using a USB hub to connect the unit to a PC, it is strongly
recommended to power the unit with a fully charged battery.
• Firmware Update
- From the main menu select “Setup”→“Firmware update”→“Yes”. The
unit will then enter the Firmware Update mode.
- Connect a USB cable between the unit & a PC. After connection, the PC
will detect the unit as a USB storage device named “USB UPDATE” and
the OLED display will read “Paste FW File...”.
- Copy and paste a valid firmware *.BIN file into the USB UPDATE drive.
- After successfully copying the file, the unit will begin the update process.
The OLED display will read “Programming...” followed by the HDCP
button blinking rapidly. Please do not turn off the power during the
programming phase.
- Once the update is complete the unit will automatically reboot.
• Factory Reset
- To return the unit to its factory default settings, please press and hold
the “HDCP” key while powering the unit on.
• PC Control Software
- This unit may also be controlled via a Windows PC software application.
For more details, please refer to the separate Control Software for
Signal Generator & Analyzer manual.
• Cable Testing
- The cable testing feature performs tests based on the HDMI 2.0 error
rate tolerance specification for 18Gbps signals and is provided as an
advisory tool only. It is recommended that each cable under test should
be tested at least three times to help eliminate outlier results.
