The CopperHead 3400 Base Station Digital Display
The Base Station digital display has three functions selected by the Display Mode selector
button (#14 on
Figure D-2 ). These functions are indicated by the Display Mode LEDs (#12).
• 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 being generated by the Camera Unit as
measured at the Base Station. Displayed in units of –dBm.
• DIAG – One of four diagnostics 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. 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 button 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. Following this sequence will allow you to understand what the various
readouts and four-character abbreviations mean for the system.

Base Station Digital Display Activity Explanation
(assumes after initial power up – see Powering the System on page 65 for a description of the Power Up
sequence)
BASE RX (Base Station Receive Signal Strength)
BASE RX -9 Indicates that the Base Station signal strength is -9 dBm
BASE RX OPT Indicates that the Display is showing Optical link signal strength
BASE RX -9 Repeat of the Base Station signal strength
BASE RX OPT Repeat that the display is showing Optical link signal strength
This display cycle repeats itself and depending on timing may start with
either OPT of the strength measurement.
CAM RX (Camera Unit Receive Signal Strength)
CAM RX COPT Sequence starts with COPT to indicate camera optical signal strength
CAM RX -9 Indicates that the signal strength from the Camera Unit is -13 dBm
CAM RX OPT Indicates that the Display is showing Optical link signal strength
NOTE: the only way to distinguish between BASE RX and CAM RX is to
check the Display Mode LED indicator.
CAM RX -9 Repeat of the Camera Unit signal strength
CAM RX OPT Repeat that the display is showing Optical link signal strength
