firmware within the unit becomes corrupted (possibly during a failed firmware
upgrade), the unit may not start up properly, and thus would be unable to
automatically enter Firmware Download mode. Using this power-up key will allow
you to upload new firmware to the unit from the Uploader software.
Self-Test Mode
Holding down the Bypass key while turning on the unit will force the unit into Self-
Test mode. Self-Test mode will allow the operator to test the front-panel controls and
indicators of the unit. The display panel will indicate which particular controls and
indicators are being tested.
When testing buttons, each press of a button will be reported on the display panel,
with the name of the button. Turning the control knob ends the testing of buttons.
When testing LEDs, each column of indicators on the buttons will light consecutively
left-to-right. Each row of indicators on the buttons will then light consecutively top-
to-bottom. The columns and rows of the stand-alone indicators will follow the same
pattern, and the process will repeat. Press any button to end the testing of LEDs.
When testing the control knob, each turn of the control knob is reflected in a numeric
value shown on the display panel. Pressing any button ends the testing of the control
knob, and begins the testing of buttons again.
To exit Self-Test mode, the unit must be turned off and back on, or reset using the
Reset Button.
Erase Firmware
Holding down the Keyer key while turning on the unit will erase all FPGA and
firmware files from the unit’s memory. This will have to be done if you are
attempting to upgrade the unit’s FPGA’s or firmware, but there is not enough
available memory to upload the new file. WARNING: after performing this
operation, replacement FPGA and firmware files must be uploaded to the unit
before the unit will be operational again.
Factory Reset
Holding down the Memory key while turning on the unit will perform a factory reset
by clearing the unit’s non-volatile memory. WARNING: all configuration options
will be reset to factory defaults. All saved settings presets will be lost.
