Autodome Camera Or Receiver/Driver Site Configuration; Controller Operation; Controls/Indicators - Philips AutoDome LTC 5136 Serie Manual Del Usuario

Connect the supplied 360 cm (12 ft) data cable with two RJ-11
connectors between the junction box and the interface unit.
The orientation is not important -- either end may be
connected to either device.
The next step is to connect the biphase control code output of
the interface unit to the data cable. Typically, a single camera
site receiver/driver is connected, but the biphase output of the
interface unit is rated to handle up to 8 receiver/drivers when
connected in a "daisy chain" configuration to a maximum of
1.5 km (5000 ft). For a "daisy chain" connection, the cable is
"looped" through each AutoDome camera or receiver/driver
along the way. The last (and only the last) unit in the "daisy
chain" connection should be terminated. All other
receiver/drivers should have their terminating resistor removed
when the 'looping' cable is connected.
If necessary, it is possible to 'expand' the single biphase output
of the interface unit using a LTC 8780 Series accessory unit.
The LTC 8780 Series unit provides up to 15 individual biphase
outputs, each rated to handle up to 8 receiver/drivers when
connected in a daisy chain configuration to a maximum of
1.5 km (5000 ft). Follow the instructions supplied with the
LTC 8780 Series unit to configure it as a biphase distribution
unit.
Connect shielded-twisted-pair cable (Belden 8760 or equivalent)
between the camera site receiver/driver location and the biphase
output connections located on the interface unit. The
removable terminal block has four connections: "+", "-", and
two "S" (Shields) as shown in the diagram below.
Interface Unit Supplied with LTC 5136
Select and maintain a wire color convention to avoid confusion
at the camera site(s).
Example: White to "+", Black to "-", and Shield to "S".
Note that either one of the 2 shield terminals of the interface
unit can be connected to the shield wire of the cable.
4.5 AutoDome Camera or Receiver/Driver Site
Configuration
Follow the standard installation instructions as provided with
the AutoDome Camera or Allegiant series Receiver/Driver unit
to connect the data cable to the unit. Set the Thumbwheel
located in the AutoDome camera or receiver/driver to the
camera number that will be selected on the Controller keypad.
Any desired camera number from 1 and 9999 can be used.
Video signals from the camera site are NOT connected to the
Controller. The video signal(s) from the camera site(s) should
be connected to an appropriate viewing monitor or other video
processing equipment (switcher, multiplexer, etc.).

CONTROLLER OPERATION

Operation is quite simple. If the camera number to be
controlled is not visible in the LED displays, use the numeric
keypad to select the desired camera, then press the ENTER
button. The camera can now be operated using the appropriate
joystick and/or lens controls. If appropriate, prepositions scenes
and auxiliary functions can also be entered as desired.
Note that a delay lasting greater than 3-4 seconds while entering
a selection will result in the Controller returning to the default
camera entry mode. If this condition occurs, simply begin the
selection again from the beginning.
A complete description of the controls and indicators is
provided in the section below.
5.1

Controls/Indicators

LED Indicators: The four digit, 7-segment LED display is used
to display data entry and the selected camera number.
SET key: This key is used to set preposition scenes of all
AutoDome cameras and Allegiant series receiver/drivers which
are equipped with this option. Operate the joystick and lens
controls to position the camera to the desired scene to be
programmed. Press the SET button, then enter the desired
preposition number on the numeric keypad (1 to 99). Press
ENTER to store the position.
Certain preposition numbers are also used to program certain
AutoDome features. Refer to the AutoDome operation manual
for a complete listing of the available features.
USER key: This key is used to enter the Controller diagnostic
mode. This test can be used to ensure that all Controller LEDs
and buttons are in working order. This function will also
automatically calibrate the center position of the analog joystick.
Upon entering this mode, the Controller will sound a short
beep. The display readouts and LEDs behind the first two rows
of buttons will also light for about two seconds. During this
time the joystick will undergo calibration, so be careful not to
move it until the LEDs displays have gone dark. Also, the
operator should note if there are any LED display failures
during the time that they are lit.
