Chapter 1 11111 About this manual 1 1.1 Intended readers About this manual This is an installation manual for the SAILOR CAS 3500/3700 Headend system, intended for installers of the system and service personnel. It is important that you install the system according to the guidelines in this manual. 1.2 Precautions Text marked with Warning, Caution, Note or Important show the following type of data: Warning: A Warning is an operation or maintenance procedure that, if not obeyed, can cause injury or death. Caution: A Caution is an operation or maintenance procedure that, if not obeyed, can cause damage to the equipment. Note: A Note gives information to help the reader. Important: A text marked Important gives information that is important to the user, e.g. to make the system work properly. This text does not concern damage on equipment nor personal safety. All personnel who operate equipment or do maintenance as specified in this manual must know and follow the safety precautions. The warnings and cautions that follow apply to all parts of this manual. Warning! Before using any material, refer to the manufacturers material safety data sheets for safety information. Some materials can be dangerous. 1

Chapter 1: About this manual Caution! Do not use materials that are not equivalent to materials specified by Cobham SATCOM. Materials that are not equivalent can cause damage to the equipment. Caution! The system contains items that are electrostatic discharge sensitive. Use approved industry precautions to keep the risk of damage to a minimum when you touch, remove or insert parts or assemblies. 2 Precautions

Chapter 2 Installation 2 2.1 General description The SAILOR CAS 3500/3700 Headend integrates all required components for a professional maritime TV/Radio-Headend system. Separate bandamplifiers make it especially suited for use in areas with high channel load by keeping inter-modulation to a minimum. It amplifies analogue as well as digital signals from long wave to UHF. Automatic Level Control circuits (ALC) help maintain the output level stable under the varying conditions aboard ships. The basic system is easily expanded to include one or more modulators. 2.2 Initial inspection Inspect the shipping cartons immediately upon receipt for evidence of damage during transport. If the shipping material is severely damaged or water stained, request that the carrier's agent be present when opening the cartons. Save all box packing material for future use. 22222 Installation Warning! To avoid electric shock, do not apply power to the system if there is any sign of shipping damage to any part of the front or rear panel or the outer cover. Read the safety summary at the front of this manual before installing or operating the system. After unpacking the system, i.e. opening the cartons, inspect it thoroughly for hidden damage and loose components or fittings. If the contents are incomplete, if there is mechanical damage or defect, or if the system does not work properly, notify your dealer. 3

Chapter 2: Installation 2.3 To install the SAILOR CAS 3500/3700 Headend 2.3.1 Overview For optimum system performance, some guidelines on where to install or mount the different components of the SAILOR CAS 3500/3700 Headend System must be followed. Mounting and placement details are included in this section. 2.3.2 Mounting considerations There are two ways to mount a SAILOR CAS 3500/3700 Headend: Cabinet mount for wall installation 4 To install the SAILOR CAS 3500/3700 Headend

19 inch rack version Chapter 2: Installation 22222 Installation Mount the headend in a dry and well-ventilated indoor environment. Mounting type Cabinet mount Cable lead Through bottom flange 19 inch rack mount Through aperture slots on the rear side as well as from the top side and bottom side Table 1: Cable lead 2.3.3 Output gain adjustment Preferably, the output gain adjustment is done using a signal generator connected to the first input of the system (input from PS3522) and using a spectrum analyzer or a suitable TV instrument to measure signal levels throughout the network. An injected signal level of 60 dbuv should result in signal levels in all outlets in the range of 60-80 dbuv, preferably closer to 60 dbuv. Minor deviations can be accepted, but at signal levels below 50dBuV analog transmissions generate a noisy picture. Levels that are too high can be reduced by adjusting the gain control on each CAS module. To install the SAILOR CAS 3500/3700 Headend 5

Chapter 2: Installation If there is no test equipment available, the gain adjustment is carried out by simply adjusting the gain until the picture is as good as possible in the cabins most far away and also the ones closest to the CAS system. A too strong signal might cause Moire-patterns on the screen, and too low levels will result in noisy images. In some cases the gain level of the amplifiers is not sufficient to compensate for system losses, due to long cables. The problem can be solved either by changing the cable path or by an installation of one or more line amplifiers. In some ports severe reflections from buildings, cranes etc. can cause distortion to the TV-picture due to the characteristics of the omnidirectional receiving antenna. There is no remedy for such a problem. 2.3.3.1 Supply voltage and cut-out relay The SAILOR CAS 3500/3700 Headend uses the SAILOR PS3522 Power Supply. This power supply handles input voltage in the range of 100-250 VAC. It supplies 15 VDC voltage to the active SAILOR Mark and SAILOR VPA antennas and antenna combinations. It also supplied 24 VDC to the cassette modules. Connect the cut-out relay function to the SAILOR PS3522 using either 24 VDC control voltage or a not-energized relay or switch.

Video and audio input levels can be adjusted from the front panel, as well as the RF output level. You can install the module in a cabinet or separately. The supply voltage is fed from the power supply to the unit by loop-connecting the supply cable from module to module. When combining the signals to a CAS 3000/CAS 3700 system take special precaution to avoid interference with terrestrial signals. Consult your distributor for further advice.

Chapter 3 BM4 VHF/UHF DSB Modulator 3 3.1 General description The BM4 VHF/UHF DSB Modulator features four separate double-sideband S-channel modulators capable of operating in PAL B/G, D/K, I, M/N and NTSC M/N. Video and audio input levels are adjustable from the front panel as well as the RF output level. The unit is especially suited for connection with the S-band input on the SAILOR CAS 3500/3700 Headend systems. You can install the module in a cabinet or separately. The supply voltage is fed from the power supply to the unit by loop-connecting the supply cable from module to module.

For example; if channel S13 is used, the S14 must be empty, meaning that the next modulator should use S15. Otherwise there will be picture distortion and interference between the modulated signals. 18 Channel tables
