The CopperHead 3404 Base Station Digital Display
The Base Station digital display has three functions selected by the Display Mode Selector
(#12 on the Overview Diagram). These functions are indicated by the Display Mode LEDs.
• BASE RX - Base Station Optical Power or Signal Strength that is being generated at the
Base Station and sent to the Camera Unit. Displayed in units of -dBm.
• CAM RX - Optical Power or Signal Strength generated by the Camera Unit as measured
at the Base Station. Displayed in units of -dBm.
• DIAG - One of four diagnostics sub-modes available to the Base Station:
• TEMP - displays operating temperature in degrees Centigrade of each circuit board
that reports temperature
• POWR - displays power level from monitored circuit boards
• REV - displays microcontroller firmware version from each circuit board with a
microcontroller
• CAM - displays the error status reported by the Camera Unit
To select the different display modes push the Display Mode Selector. To enter the
DIAGnostic mode, push and hold the Selector for five seconds. The transition from one
mode to another may take a moment with the transition into the Diagnostic mode taking
slightly longer. The Selector is cyclical rotating through each of the modes. Once in the
Diagnostic mode, a quick push of the Selector cycles through the various diagnostic sub-
modes described above.
The following table describes the expected readouts in each of the above Base Station
display modes. By following the sequence, you can understand what the various readouts
and four-character abbreviations mean for the system.

BASE RX (Base Station Receive Signal Strength)
BASE RX LED LIT
BASE RX -9 Indicates that the Base Station signal strength is -9 dBm
(typical power rating - value will reflect actual link
strength at the time.
BASE RX n/A Indicates that there is no active fiber link between the
base station and the camera unit
