For Dennard 2060 drx units
These domes can be controlled from any controller that can be set to output BBV up the coax
protocols e.g. Dennard, Building Block Video & Dedicated Micros
The dome is addressed with the blue switch on 0 and the yellow switch on 1
(Dennard 2060 drx domes are supplied with this setting by default)
For RS485 control units
The domes need to be addressed to the camera positions and the address switch setting table can
be found in the Dennard 2060 Operation Manual.
SETTING UP PRESETS
Preset positions of 16 or less may be set up using the controller programming facility. For preset
numbers over 16 then the Dennard 2060 dome programming must be used. The controller buttons
used to achieve Dennard 2060 menu access for the more popular Controllers are shown in the
Dennard Menu System manual.
When the preset number has been keyed in an “Alphabet Menu” will appear offering you the
chance to identify that preset. To do that, select a letter by moving the cursor to a position under the
letter by using the joystick then press the keyboard “accept” command to place it on the monitor. Do
this for each letter required to spell out the location name. Finally move the cursor to Accept Entry
and press the “accept” command button(s), which will clear the menu. If identification is not
required, move the cursor directly to the Accept Entry prompt and “accept”.
BASIC TROUBLESHOOTING GUIDE

Check the PSU input and output voltages.
Check the PSU fuse.
Check the continuity on the dome multicore cable: PIN 1=Video PIN 2=Video Screen PIN
3=Data+(yellow) PIN 4=Data- (green) PIN 5=18volt neutral (blue) PIN 6=18Volt live (red) PIN
7=Earth (drain wire)

If the control is via a DRX protocol converter, or any other type of protocol converter make sure the
data cables have been connected and are in the correct positions.
Check that the dome address switches are set in the correct position for the type of controller being
used.
Picture with intermittent control
This problem is often due to too much or too little video gain.
If you are using the DOME in the co-ax mode then the video levels need to be set up to 1 volt p-p.
This is achieved by accessing the Technician Menu of the dome. Select Miscellaneous Services
and from this menu select Host Comms / Video Amp and adjust lift and gain to suit.
