Miscellaneous Services - Dedicated Micros Dennard 2040 Manual

The linear speed setting alters the speed at which the dome rotates and tilts. The range can be set
from 1 (slowest) to 8 (fastest). It may be desired to reverse the direction of the joystick in relation to
camera movement or cursor positioning. These are all selectable from the screen.

4.4.4 Miscellaneous Services

This facility groups together a range of data and settings that may be useful to the technician in
fault finding. The following options become available:
Host comms/video amp
Software version
Homing values
Home servos
NVM Services
Reset Head
Return
Exit
Selecting 'Software version' will briefly display the programmed software revision level at the top of
the screen. Similarly, 'Homing values' will briefly display encoder values from the pan and tilt
motors.
'Home servos' will perform a motor reset where the dome will go into a routine where it pans and
tilts through its ranges to re-establish its base position.
'Reset head' provides a reboot to the dome. It will perform its power-on self test and then home its
servos.
4.4.4.1 Host comms/video amp
Selecting this brings up the following screen:
Activity LED:
Host polling:
Video gain:
Video lift:
Save and Return
Save and Exit
The small green LED in the dome can be switched on or off. This can be useful to check if power is
reaching the dome but it may be visible in low light conditions.
Host polling determines whether the dome responds to messages in half duplex serial
communications, or acts in simplex mode without answering. This will depend on the controller
being used and the configuration of the dome communications.
The video signal may require boost and lift to compensate for different types or lengths of coax.
Video gain is factory set at 1 with Video lift off and different settings are made in the usual way.
