4.7 Accepting the request for multiplexers
Accepting the multiplexers is used to prevent an unauthorised operator from operating multiplexers that are not
within his duties.
4.7.1 Default sett ing
The default setting allows control of all multiplexers, erasing any previously defined setting.
4.7.2 Modifying the list
The procedure for accepting and disabling the multiplexers is the same as that just described for the cameras
(see § 4.5 - Accepting requests for cameras and assigning receivers, page 16).
Usually 39 multiplexers can be selected from the keyboard.
4.8 Accepting requests for functions
Each operator can be enabled (or not) to carry out specific operations from the keyboard.
These are divided into groups of functions and are:
: enabling camera selection with the and keys; since these keys are able to cause a
break in the automatic sequence it may be necessary to disable them if this likelihood is to prevented.
: enabling monitor change; if an operator has a single monitor, this can be frozen so that it
cannot be changed any more.
: enabling video device (switcher or matrix) setup; even if enabled this can be subject to
insertion of a password
: enabling dome or telemetry receiver setup; if enabled this can also be subject to a password
: enabling reset of video device alarms; if enabled this can also be subject to a password
: enabling use of joystick
enabling control of lens functions in telemetry receivers
: enabling changes to pan & tilt /dome movement by sending autopan and scan type
commands
: enabling change to receiver number associated with a camera
