ACTION
Check the PSU fuses
Check the input and output voltages
Check all co-ax connections
Continuity check the dome multicore cable:-
Pin 1 =Video
Pin 2 =Video screen
Pin 3 =Data + (Yellow)
Pin 4 =Data(Green)
Pin 5 =24Volt Neutral (blue)
Pin 6 =24Volt Live (red)
Pin = Earth (drain wire)
If control is via a Dennard drx100 protocol converter, check that the Green
and Yellow wires from the dome are connected correctly ie Green to C1
Yellow to C2. Using a video level metre, check the sync pulse is 0.3V
If control is via RS485 check that the data connections are:-
Green Wire data - Yellow Wire data +
If control is via a Dennard 2060 co-ax (which has built in protocol
converters), control is "up the co-ax" but the address switches have to be
set to suit the controller protocol. See the Operation/Installation Manual for
settings.
This problem is often due too to much or too little video gain.
If you are using the Dennard 2060 co-ax dome with built in protocol
converters, video amplification is accessed through the menu system.
Refer to the manual and adjust the gain to suit.
If you are using a Dennard 2060drx as per Dennard 2040drx then the
Video Gain can be found on the drx card behind the BNC connectors
located in the PSU box
This indicates that the Dome software has detected an error. Before
contacting Dennard Technical on 01420 485713 the error display should
be enabled as this will help Dennard Technical to solve your problem.
See section 4.4.2 for details on this.
This may be because the Baxall controller has been configured to
ALTERNATE mode which is not supported by the Dome. Setting the
dome to STANDARD mode with Rx set to DC should solve the
problem.
This may be due to the joystick having no 'dead band', possibly through
the joystick being off centre on power up. Power the controller down
then power up again ensuring that the joystick is free to self-centre.
