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.
• COPT – 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.
• BOPT – Base Power (Remote OPTical) or Signal Strength generated by the Base Station
as measured at the Camera Unit. Displayed in units of –dBm.
• 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
• 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 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 Operating the Transceiver System
on page 63 for a description of the Power Up sequence)
COPT - Camera Unit Optical Signal Strength
-9 Indicates that the Base Station signal strength is -9 dBm
OPT Indicates that the Display is showing the 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.
BOPT (Base Optical Signal Strength)
A quick push of the BASE Rx/DIM selector advances to the BOPT mode
BOPT Sequence starts with BOPT to indicate base optical signal strength.
bOPT Indicates in the base 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 - BOPT does not reappear in the repeating
cycle.
DIAGNOSTIC MODE Temperature (TEMP)
A quick push of the BASE Rx/DIM selector advances to the TEMP mode
