Dip switches settings |
| The DIP-SWITCHES can be found on the ceiling
mount base of the unit. |
| Machine Identity: |
When using a multi-drop system with a remote control unit,
a machine identity needs to be set for each camera. There are 2
rotary DIP-switches for setting the Machine Identity of the
camera. Set the left rotary DIP-switch
as figure of 10 and the right one as figure of 1
(decimal notation). This value must match the machine
identity value in the remote control unit (see below
under Driver Specific Settings).
|
| DILSWITCH:1-8 |
Set the DIP-switch as
follows (0 = OFF, 1 = ON): "0, 0, 1, 1, 0, 0,
X"
For the last unit on the RS485 serial bus, set X=1
(enable RX termination).
For all other units, set X=0 (disable RX termination).
|
| Description of the switch settings: |
|
1, 2 |
= |
OFF, OFF : Reserved, must be OFF |
| 3 |
= |
ON : No display
of "MANUAL" in the screen.
OFF: Display "MANUAL" in the screen when
remote control is used |
| 4 |
= |
ON : Use multi drop protocol
OFF: Use point to point protocol |
| 5 |
= |
ON : Use simplex
communication protocol
OFF: Use duplex communication protocol |
| 6 |
= |
OFF: Use internal
vertical sync.
ON :Lock the vertical sync to the AC power line |
| 7 |
= |
OFF: Reserved, must be OFF |
| 8 |
= |
OFF: Disable RX
termination (110 ohm)
ON : Enable RX termination (110 ohm) |
|
|
Driver Specific settings
|
| Identity: |
This is the machine identity of the connected device. This value
must match the rotary DIP-switch
settings in the camera (see above).
|
Movement,
Picture Speed: |
This is
the maximum speed used with click-in-picture movement.
This speed depends on the distance from the center of
the image - the further away from the center the higher
the speed becomes, and reaches its maximum value at the
edge of the picture.
|
Movement,
Picture Time: |
This is the time between the start and the
stop commands for a click-in-picture movement. This time
is independent of where in the picture you click.
|
Movement,
Move Speed: |
The
Speed used when one of the 8-arrow buttons are clicked
and when the CGI commands "rpan" and "rtilt" are
used.
|
Movement,
Move Time: |
This value is the time it takes for the dome
to move one degree at the speed given above. Used when
one of the 8-arrow buttons are clicked and when the CGI
commands "rpan" and "rtilt" are used.
|
| Zoom,
Time: |
The
maximum time for a zoom move, used when you click the
ends of the relative zoom bar. If you click closer to
the center the time will be scaled to reflect this, i.e.
the further from the center you click, the longer the
time used. This also affects the "rzoom" cgi-command.
|
| Digital Zoom: |
The maximum digital zoom that can be used (the
digital zoom will be temporary disabled when saving a
preset position).
|
| Focus, Time: |
The maximum time for a focus move, used when
you click the ends of the relative focus bar. If you
click closer to the center, the time will be scaled to
reflect this. i.e. the further from the center you click,
the longer the time used. This also affects the "rfocus"
cgi-command.
|
| Iris,
Time: |
The
maximum time for an iris move, used when you click the
ends of the relative iris bar. If you click closer to
the center, the time will be scaled to reflect this, i.e.
the further from the center you click, the longer the
time used. This also affects the "riris"
cgi-command. |
