1.1.13
Host polling
The Dennard protocol allows either half-duplex (ON) or simplex operation (OFF). The
dome is delivered set for 'simplex' operation..
1.1.14
Error Reporting
The Dennard Dome constantly monitors its own health, and should any difficulties occur
(for instance, with dome protocol responses enabled it will be able to signal that there is
an intermittent serial control problem, which would otherwise be undetectable) is able to
indicate what may be wrong by a flashing square in the top right hand corner of the
transmitted picture; the cause can subsequently be requested when convenient. This
reporting can be disabled from the Technicians menu.
1.1.15
Activity light
A green led provides some diagnostic help when first switching the dome on and also
indicates when command signals are received. As it may be visible externally it can be
switched on or off.
1.1.16
User Timeout
There is a possibility that the dome may be left pointing at an unhelpful scene and for
whatever reason ‘forgotten’. To cater for this eventuality, three pre-sets have the
specific function of acting to prevent this happening. These are Position 001, Sequence
001, and Queue 01.
A delay of between 1 and 999 seconds may be set, and if this time is exceeded after
any joystick/key entry Pan and Tilt input at the Control Panel then the default action will
occur. Once set the delay time is displayed
If a delay time of 0 is set, no default action will occur.
If a Dome menu is left waiting for an input for more than 3 minutes then the system
times out and the dome resumes its previous activity.
1.1.17
Set video amplification
This facility allows the video gain to be increased from the normal setting in three steps
to a maximum setting. Video lift can be tuned on or off, it is normally set to the off
position. A double arrow to the right of the menu indicates the current selection.
1.1.18 Privacy
mode
It is sometimes desirable to prevent operators from viewing certain areas. To meet this
requirement the Privacy mode allows black patches to be set up to cover these areas.
The size of the patch is the size of the monitor view at whatever zoom setting is used.
When zooming out the patch reduces in size so that it only covers the original area.
