The CopperHead 3400 Camera Unit Digital Display
The Camera Unit Digital Display has six functions selected by the BASE Rx/DIM Selector (#11 on the
Overview Diagram). These functions are indicated only by the activity in the Digital Display.
1. LOPT – Camera Unit Optical Power or Signal Strength (Local OPTical) that is being generated at
the Camera Unit and sent to the Base Station. Displayed in units of –dBm.
2. ROPT – Optical Power (Remote OPTical) or Signal Strength generated by the Base Station as
measured at the Camera Unit. Displayed in units of –dBm.
3. TEMP – displays operating temperature in degrees Centigrade of each circuit board that reports
temperature
4. POWR – displays power level from monitored circuit boards
5. REV – displays microcontroller firmware version from each circuit board with a microcontroller
6. 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 Page 66 for a description of the Power Up sequence)
LOPT (Camera Unit Optical Signal Strength)
-9 Indicates that the Base Station signal strength is -9 dBm
OPT Indicates that the Display is showing Optical link signal strength
-13 Repeat of the Base Station signal strength
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
ROPT (Base Station Signal Strength)
A Quick push of the BASE Rx/DIM Selector advances to the ROPT mode
ROPT Sequence starts with ROPT to indicate remote optical signal strength
rOPT Indicates in the remote optical signal strength cycle
-9 Indicates that the signal strength from the Base Station is -9 dBm
This display cycle repeats itself and depending on timing may start with either OPT of the strength
measurement – ROPT does not reappear in the repeating cycle
