Using a video level metre, check the sync pulse is 0.3VIf 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 protocolconverters), control is “up the co-ax” but the address switches have to beset to suit the controller protocol. See the Operation/Installation Manual forsettings.Picture with intermittentcontrolThis 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 protocolconverters, 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 theVideo Gain can be found on the drx card behind the BNC connectorslocated in the PSU boxFlashing cursor size boxtop right corner of monitorThis indicates that the Dome software has detected an error. Beforecontacting Dennard Technical on 01420 485713 the error display shouldbe enabled as this will help Dennard Technical to solve your problem.See section 4.4.2 for details on this.On Baxall controlledDomes, alphabet menupops up when the joystickis touchedThis may be because the Baxall controller has been configured toALTERNATE mode which is not supported by the Dome. Setting thedome to STANDARD mode with Rx set to DC should solve theproblem.On Dennard & BBVcontrollers the domespins continuouslyThis may be due to the joystick having no ‘dead band’, possibly throughthe joystick being off centre on power up. Power the controller downthen power up again ensuring that the joystick is free to self-centre.(Applicable to Dennard 2060 only)
