Telecast Fiber Systems

Introduction The Cobra™ is a high-performance link that interconnects triax-equipped cameras to their base stations using lightweight fiber optic cable. By use of a Personality Module specifically installed in each Cobra chassis, compatibility is achieved with a wide variety of cameras and base stations. Both Camera and Base Station unit Cobras can be installed in a 19 inch electronics rack or used as portable units with a carrying handle. Mounting brackets attach to the sides for rack mounting. The Cobra maintains component video levels for maximum flexibility and performance. The bidirectional system supports all CCU functions over long distances, including return video and intercom. The Cobra also provides power to the camera; more than 1,000 feet (300 m) of triaxial cable can be driven, if necessary. Camera-specific Personality Modules that adapt the system to various camera and triax connector types are installed into the front panel of each Cobra chassis. The power supply adapts to and supports virtually all known triax systems by configuration of the Personality Module, including: • AC and DC powered cameras, and • Component, Composite, RGB, wideband and High Definition cameras. Special features of the Cobra system include • Safety power interlock • Wideband, low noise operation • Flexible triax connector options • Full CE safety rating

Unpacking the Cobra The Cobra system consists of four parts: the two Cobra chassis — one for the CCU end and one for the camera end — and the two Personality Modules that correspond to the type of camera being used. The Personality Module is shipped pre-configured and installed in the Cobra chassis according to the sales order. The system is assembled by carefully sliding the Personality Module into the corresponding chassis. Each Personality Module is labeled in three places as to whether it is the base station end or the camera end: twice on the faceplate and also at the rear of the PC board attached to the faceplate. Make sure that the correct module is installed into each chassis.

Installing the Personality Modules 1. On a flat surface, be sure that you have the chassis and Personality Module for the base Station end of the camera chain. 2. Locate the rails in the chassis and insert the personality module onto these rails. 3. Fully slide the Personality Module into the chassis and tighten the thumb-screws. All internal connections are made at the rear of the Personality Module and are invisible to the user. Perform the same above procedure when installing the Personality Module into the Camera end chassis. 1

Cobra™

Setting Up a Cobra System The chassis is completely sealed on five sides. All connections are made to the remaining side, the front panel, which houses the Personality Module. This construction assures maximum imperviousness to difficult field environments while providing a unit also suited for permanent installation. The Personality Module is a plug-in module which contains the appropriate circuitry necessary to properly interface with the selected camera. Personality Modules are specific to the camera type used in the link. The Personality Module plugs into the front panel on both Camera and Base Station units of the link; see Figure 1. The faceplate of the Personality Module is labeled with the module ID from which you can identify compatible camera types. Figure 1 shows the camera interface for use with wide band Sony and Ikegami base stations.

Figure 1. Cobra Front Panel- 2 Fiber System The interconnections between the Cobra Base Station unit and the Cobra Camera unit with its video camera are shown in Figure 2. Connections to both units are identical. The primary power source is from AC line power into the Power Entry Module. This module is further discussed in the next section. The system operates properly from 47 to 65 Hz and within ± 10 volts. Triax RF In/Out Camera Power In Triax RF In/Out

Figure 2. Cobra Interconnected Video System 2

Telecast Fiber Systems The video, audio, intercom and control signals are carried by the optical fiber between the Personality Modules at the Cobra Camera unit and the Cobra Base Station unit. Triax cable is used to connect the camera CCU to the Base Station end Cobra and to connect the video camera to the Cobra Camera unit. Since the optical fiber cannot carry an electrical current, power for the camera is provided by a power supply built into the Cobra camera-end unit.

Operation of the 120/240 VAC Power Entry Module The Cobra can accept either 120 VAC or 240 VAC by use of the Power Entry Module, shown in Figure 3 The unit accepts AC line voltage with a standard IEC/NEMA type power cord. A window on the Power Entry Module reflects the current VAC setting, either 120 or 240. Verify that the voltages on the units are set properly before operating the system.

Changing the Input Voltage Perform the following steps when changing the input voltage to the Cobra: 1. Use a small, flat-blade screwdriver in the notch at the top of the module to gently pry open the module cover and expose the fuse block. The cover is hinged at the bottom and will open easily. 2. Gently pop out the fuse block. 3. Turn the block over and replace it back into the module. 4. Close the module cover. The new input voltage value will be reflected in the voltage value window. Note: The same procedure is followed for fuse replacement. Be careful to replace fuses with ones of equal voltage, current and duration.

Figure 3. 120/240 VAC Power Entry Module 3

Cobra™ Cobra Line Voltage Selection The Cobra systems operate on AC mains power and can work with a variety of voltages. The internal power supply can be set for two operating ranges: 120/240 VAC (normal) and 100/200 VAC (low) +/- 10%, both at 50/60 Hz. To change from Normal to Low line voltages, it is necessary to change the transformer connections to the Power Entry Module. Remove all external connections from the Cobras. Remove the (7) #4-40 and (3) #2-56 screws in the Cobra faceplate and carefully withdraw the chassis from the cover. The connections to the transformer are color-coded and are connected to the Power Entry Module with 0.187" pressed-on spade-type connectors ("Fastons"). Warning: Warning: Be sure to remove all external connections from the Cobra including the power cord before attempting these changes. To convert from Normal to Low voltage operation remove the YELLOW and BLACK transformer leads from the Power Entry Module. Cover these leads with insulation (electrical tape) to prevent contact with the chassis or other components. Connect the unused BLUE and RED leads according to the Table 1, below. It is imperitive that the leads go to the correct positions or damage to the Cobra may result. Re-assemble the Cobra to complete the conversion 100/200V D C B A

Table 1. Power Entry Module Connections To convert back to Normal voltage, reverse the above procedure. Warning: Read the following paragraph before attempting to hook up your Cobra system. High voltage, 250 VAC or 300 VDC, is generated within the Cobra Camera unit and appears on the triax connector.

Camera High Voltage and Safety Interlock The 250 VAC or 300 VDC high voltage to operate the video camera is developed in the Cobra Camera unit and carried over the triax link to the camera. The voltage is determined by the specific Personality Module installed at each end of the Cobra link. Line voltage is displayed above the power switch, which is above the line cord entry point. When the power switch is on, the AC ON LED illuminates. The RX STATUS LED illuminates when receiving an optical signal. See page 8 for a more complete explanation of this LED. Fiber connections are below the LEDs. Refer to Figure 4. 4

Telecast Fiber Systems

Figure 4. Front Panel Indicators and Power Input - Dual and Single Fiber Systems The Cobra power supply output voltage is enabled by the presence or absence of a triax connection between camera and Cobra. Various voltages are available at the backplane of the Cobra. When a Personality Module is inserted, the correct voltage for that particular camera is made available at the triax connector. This serves as a safety feature to keep all high voltages away from the user. The HV PRESENT LED located next to the triax connector on the camera-end Personality Module illuminates whenever voltage is available to the camera. Note: It is not necessary for the fiber link to be present or for the base station to be on for the video camera to be powered up. The Cobra supplies voltage whenever it detects the intercom signal on the camera triax.

Personality Modules The Personality Module is specific to the camera type used in the link. A triax connector provides the interface with the selected camera. All low level signal processing as well as voltage selection and control is provided on this module. Status indicators for functions relevant to the particular module type are provided. See the Faceplate Indications section beginning on page 11. A safety interlock disables internal high voltage when the Personality Module is removed. With the exception of the WB and SB Camera End Personality Modules, discussed below, there are no user servicable parts or switches on the Personality Modules. A representative module front panel and circuitry is shown in Figure 5.

Figure 5. Personality Module

SB & WB Personality Modules for Sony and Ike Cameras The Camera End Personality Modules for certain Sony and Ikegami cameras have one or two user configurable switches. The SB-1 Personality Module handles Sony standard band 370 and 375 as well as Ikegami standard band 323A/355/366 and 377-LR. Since Sony cameras handle video signals as luminance/chrominance and Ikegami handles its video as RGB, we are able to accommodate both camera types on a single Personality Module. This Personality Module has two switches. The first selects between video output (component for Sony, RGB for Ikegami) and the second selects between start-up power (DC for Sony, AC for Ikegami). The position of these switches is shown in Figure 6 on the next page. It is important that these switches be set properly. They will be factory pre-configured according to your specific order. The WB-1 Personality Module handles Sony wideband 500/550/700/750 as well as Ikegami wideband 388. These models use component video, eliminating one of the two switches. This module has only the switch for determining start-up power (DC for Sony and AC for Ikegami). The position of this switch is shown in Figure 6 on the next page. It is important that this switch be set properly. The switch will be factory pre-configured according to your specific order.

Hookups The following procedure details a suggested hookup sequence for the Cobra video system. Use only single mode fiber with Cobra links. Refer to Figure 7 on the next page. Caution: Before starting a hookup, be sure that the power switches on both Cobra units are off. Also, check out each section of triax for open or short circuit conditions before using it with your Cobra system. 1. Run a triax cable from the base station (CCU) to the Cobra Base Station unit. Practical limits to cable lengths are given in Table 2 on page 9. 2. Remove the caps covering the SC/APC connectors of each Cobra unit and run the optical fiber supplied with your Cobra system from the OPTICAL I/O connector on the front of the Cobra Base Station unit to the same input on the Cobra Camera unit. Be sure that these connectors are clean and free of any dust or grime. The practical length limit for this single mode fiber is 20 km. See Figure 4 on Page 5 for the location of these connectors. 3. For Single-Fiber systems, connect the fiber to the top "A" SC/APC bulkhead connector. 7

Cobra™ 4. For 2-Fiber systems, connect the first fiber to the top SC/APC bulkhead connector "A" at each end and connect the second fiber to the bottom SC/APC bulkhead connector "B" at each end. Note: SC/APC connectors are angle polished and have green plastic bodies. The angle polish minimizes back-refections to optimize performance. Do Not attempt to connect normal, flat polished connectors (SC/PC) to this unit. These connectors have blue plastic bodies. If optional connectors have been installed on your unit, be sure to use the appropriate connector type. TAC Series fiber optic cable, supplied by Telecast, is impervious to electrical interference and can be used in temperature conditions from -55 C to +85 C. 5. Run a triax cable from the video camera to the Cobra Camera unit. Practical limits to cable lengths are given in Table 2 on page 9. 6. Set each Cobra voltage selector to match the local source. Connect a power cord from each Cobra to the AC mains source. 7. Turn power on to both Cobra units. Camera Unit

Checking Fiber Connections Once the fiber is connected on each end and the units are powered ON, the RX STATUS light will indicate the status of your connection. The position of this LED is shown in figure 4 on page 5: • A GREEN indication means that optical power is between 0 and -12 db. This is optimal. • A MIXED GREEN/RED indication means that optical power is between -12 and -16 db. The system will still function but is less than optimal. Clean your SC/APC connectors and check the fiber run for tight radius bends and other conditions that might lead to loss. 8

Telecast Fiber Systems • A RED indication means that optical power is greater than -16 db and the unit has squelched off. Clean your SC/APC connectors and check the fiber run for tight radius bends and other conditions that might lead to loss. Note: Optical measurements are +/- 1 db and optical output is nominally -0.5 db.

Transmission on Fiber and Triax Fiber Characteristics Signal transmission between the two Cobra units over a single mode fiber is bidirectional. In a single-fiber system, the two signals are at differing wavelengths and are separated by a Wavelength Division multiplexer (WDM) within each Cobra unit. • From Camera unit to Base Station unit: 1300 nm • From Base Station unit to Camera unit: 1550 nm • In a two-fiber system, the wavengths are the same at 1300 nm. • The maximum fiber length is 20 km, or an optical signal loss of no more than 10dB.

Fiber Testing Warning: Never look directly into the unit of a connected optical fiber while any component of the system is operating. Eye damage is possible. Use the optical power meter listed Accessory List on page 10 as a means of testing the optical signal level and its transmission over the fiber. Instructions for this test procedure are supplied with the power meter.

Triax Cable Lengths Triax cable losses increase in relation to the increasing frequency of the electrical signal being carried. The loss is greater when carrying a 54 MHz signal than when carrying a 36 MHz signal, and so forth. Practical limits to the length of cable that can be used are given in Table 2. Triax Diameter 3/8 inch 1/2 inch

Camera unit 250 m 400 m

Base Station unit 100 m 100 m

Table 2. Triax Lengths

Return Video Viewfinder displays in the video camera operate in two ways: • The viewfinder image is developed and displayed within the camera and is not transmitted from the base station. • The viewfinder image is developed and then conveyed from the base station back to the camera as Return Video for display. Operation is determined by the type of camera used and the specific Personality Modules installed in your Cobra system. 9
