Operation of CopperHead 3404 Transceiver System
The CopperHead 3404 Camera Unit Digital Display
The CopperHead 3404 Camera Unit Digital Display
The Camera Unit Digital Display has seven functions selected by the BASE Rx/DIM Selector
(#11 on the Overview Diagram in
Camera Unit Indicators and Controls on page 104). These
functions are indicated only by the activity in the Digital Display.
• COPT - Camera Unit Optical power being received at the camera coming from the base.
Displayed in units of -dBm.
• BOPT - Optical Power (Remote OPTical) or Signal Strength generated by the Base
Station as measured at the Camera Unit. Displayed in units of -dBm.
• DIAGNOSTICS - One of Five sub-modes
• TEMP - displays operating temperature in degrees Centigrade of each circuit board
that reports temperature
• FAN - displays and allows testing of various fan operating modes
• POWR - displays power level from monitored circuit boards
• REV - displays microcontroller firmware version from each circuit board with a
microcontroller
• LED Brightness - Allows the adjustment of the Camera Unit LED brightness
To select the different display modes push the BASE Rx/DIM Selector. The transition from
one mode to another may take a moment with the transition into the LED Brightness mode
taking slightly longer. The Selector is cyclical rotating through each of the modes.
The following table describes the expected readouts in each of the above Camera Unit
display modes. By following the sequence you can understand what the various readouts
and four-character abbreviations mean for the system.
Readout Camera Unit Digital Display Activity Explanation
(assumes after initial power up - see Powering the System on page 61 for a description of
Power Up)
After power up sequence system defaults to Camera Unit Optical Signal Strength - push
the display select button and the system displays Base Station link strength. Push and
hold button to enter diagnostics mode.
COPT (Camera Unit Optical Signal Strength)
-9 Indicates that the Camera signal strength is -9 dBm (typical power rating
- value will reflect actual link strength at the time
n/A Indicates that there is no active fiber link between the Base Station and
the Camera Unit
BOPT (Base Station Signal Strength)
A Quick push of the BASE Rx/DIM Selector advances to the BOPT mode
-9 Indicates that the Base Station signal strength is -9 dBm (typical power
rating - value will reflect actual link strength at the time
n/A Indicates that there is no active fiber link between the base station and
the camera unit
