1-4 Technical Manual LDK 20(S) - Studio Camera Safety Instructions
Section 2 Installation This section provides information which is relevant when the camera is to be used for the first time. Packing and unpacking instructions together with information on the integration of the camera into your studio system are provided. The procedures for the customization of certain hardware functions and connector information is also provided. Contents Packing/Unpacking ............................................ 2-2 Local / Remote Power Supply ............................
Packing/Unpacking Inspect the shipping container for evidence of damage immediately after receipt. If the shipping container or cushioning material is damaged, it should be kept until the contents of the shipment have been checked for completeness and the units have been checked mechanically and electrically. The shipping container should be placed upright and opened from the top. Remove the cushioning material and lift out the contents.
Hardware Setup and Customization The camera is delivered in a ready-to-use state, however, there are occasions when it might be necessary to re-adjust some functions after, for example, fitting a new lens. A large number of functions can be set-up using the control facilities of the menu system. In addition to this software set-up there are some functions which can be selected or adjusted internally in the camera. Refer to the next chapters for instructions.
Test Sawtooth Lens matching A test sawtooth signal is normally only used for adjustment procedures. Jumper X3 on Video processor 1 board provides a choice between two internal signals or an external signal. Internal signals Set jumper X3 to position BC to get the nominal sawtooth. This is used for checking amplitudes. Set jumper X3 to position AB to get a small sawtooth (approximately 25% nom.). This small sawtooth is used for checking painting or colour temperature ranges.
Analogue Ch1-Ch2 Dipswitch Settings Two analogue channels (AN 0 and AN 1) are available from the base station to the camera via the triax cable and can be used to transmit L.F. signals. For example, joystick control or pan and tilt. The input signals are applied to the Auxiliary connector of the base station. The output signals are available on the Auxiliary connector of the camera. The input signal and output signal voltage is between 0 and 5Vdc.
Viewfinder Cadre Indication Cadre On/Off Switch S6 on the Sync./shading board allows the cadre in the viewfinder to be switched on permanently or to be controlled by the menu system. Position AB selects (remote-) menu control (factory setting); position AC switches the cadre on permanently. If S6 is in the remote position then you can select in Menu VF/Lens Cadre On or Off. The cadre is switched to the 4:3 format or to the 16:9 format depending on the position of the aspect ratio switch.
Audio / Intercom settings Audio microphone signals The high-pass filters in the audio channels reduce the background noise in the audio microphone signals.
Private Data Private data channels can be used for the transmission of serial data via the triax cable. For example, electronic scriptboard or character data for a video display unit can be transmitted to the camera. To select the function of the camera to base station channel use S802 on the Audio/intercom board. Position AB selects the tracker microphone function (factory setting); position AC selects the private data function.

Introduction Printed circuit boards The instructions given in this section are restricted to those modules which can be replaced at the first line level. After a printed circuit board has been replaced it is sometimes necessary to carry out adjustments to match the new boards to your camera and so maintain the performance levels. The relevant adjustment procedures are referenced in section 4. The procedures for removing the modules should be followed in reverse order when remounting the units.
Front module 1 1 2 2 2 2 1 1 To remove the front module proceed as follows: a. On the frontside of the camera remove the four screws 1 securing the front assembly. b. Remove the front assembly from the camera. c. Remove the Front Interconnection Board by unscrewing two screws from the backside of the front module. d. Loosen the four screws 2 securing the front module. e. Slide the front module straight out of the front assembly.

Section 4 Adjustments This section contains the adjustment procedures to be followed to obtain the best performance from the camera. These procedures need only be used if, following a module replacement, the camera does not perform according to specifications. Contents Introduction .......................................................... 4-2 Test Equipment ................................................... 4-3 Set-up Instructions ...............................................
Introduction This camera is factory tested and adjusted for operational use. Under normal circumstances, the internal potentiometers do not need to be adjusted. If it is discovered that the camera is misaligned, the following procedures are given as a guide for competent service personnel, who have a thorough knowledge of the camera and have the use of calibrated equipment, to realign the camera. The camera head adjustment procedures are designed as separate units.
