Figure 7. Typical Baseband Rack Layout Diagram 7/11/95 Chapter 3: Baseband, Page 39 Rauland RANGER System Planning Pre-Ins talla tion lnforma tion RANCLI 01 and RANCLI 01 CP Classroom Controllers l You will need to pull one video cable or one fiber-optic cable to each location that will receive video from the headend. If a classroom has distributed local origination, an additional coax or fiber video cable will be required, as well as additional hardware (RANAVMSI and RANFTl for fiber). If using RS485 control in the classroom, an additional l-pair shielded data-grade wire will also need to be pulled. For more information refer to the Installation manual, KI-I 856. l If a RANCLINTF classroom cable interface plate is used in a coax-based system, the 2-gang box that will hold the RANCLINTF must be mounted within five feet of the RANCLIOI or RANCLIOICP Classroom Controller. l For fiber systems, an 8 x 10 x 4 backbox (RANBOX4) is required to hold the RANFBINT TV Interface Box. It should be mounted within 5 feet of the RANCLlOl or RANCLIOICP. l The l-pair shielded wire can be looped from one classroom to another as long as it does not exceed the maximum distance per AXLINK port specified in the documentation for the RANEXP Master Port Expander, RANEXPAD Master Port Expander, RANBROAD Master Port Expander, or RANCPU Control System Master Card. The control pair can also run on independent AXLINKS. Each link is subject to the specifications for maximum distance per AXLINK port specified. l If using a RANAVJ Audio and Video Jack, a single-gang electrical box must be mounted so that it is easily accessible for the local device (e.g., camera) that will be plugged in. Install an RG59 (or equivalent) cable and one shielded-pair to the RANCLINTF TV Interface Box. l If using a RANDATA for Level III laser disc control, a single-gang electrical box must be mounted so that it is near the computer running the Level III program. Install one shielded data-grade pair from the RANDATA to the RANCLINTF TV Interface Box. Headend Video RANCAGE Card Cage The RANCAGE is a card cage that houses Fiber, Multiplexer, and Demultiplexer cards used with a RANGER system (RANAVMS2, RANAVDS2, RANFT4, or RANFR4). This cage holds any combinaiion of ten cards regardless of the type of card. The RANCAGE requires 12 VDC at 20 mA and mounts in a four-rack unit (7”) space. Parts Required 4 Mounting screws (RB Part # B0439) and 4 washers (RB Part # WL03 15) Chapter 3: Baseband, Page 40 7/l l/95 Rauland RANGER System Planning Note: The RANxx VSyy is a modular unit.

Connection between classrooms and the media center are controlled through the RANCPU Control System Master Card which interfaces to the Video Matrix Switch via an RS232 connection. The switch then connects to the source device or other audio/video inputs through a multiplexer module (RANAVMS2) permitting the use of a video-only switch. The RANxxVSyy is available in increments of ten inputs and ten outputs. The Auto Patch Switcher is available in increments of four inputs and four outputs. Parts Required 1 Interface cable (refer to drawing VW2374 for the RANxxVSyy switch and VW2375 for the Autopatch switch) 1 Power cord (supplied with the switch) 1 RAN232 Serial Control Card (see “RAN232” for more information) Associated Equipment 1 RANCC16 Control Card Cage (see “RANCC16” for more information) 8 Mounting screws (RB Part # B0439) and 8 washers (RB Part # WLO315) for RANIVSYYI RANA VMS2 Audio/Video Multiplexer Module The RANAVMS2 is a stereo audio/video multiplexer module that combines a media resources audio and video signals onto one 75Q coax cable. This cable then connects to the video matrix switch, which then passes the signal over another 75Q coax, cable to the classroom. The RANAVMS:! consists of two multiplexer modules on one PC board allowing two resources to be connected to one RANAVMS2. These stereo audio/video multiplexer modules are housed in a RANCAGE card cage with a 12 VDC at 400 mA power source. 7/l l/95 Chapter 3: Baseband, Page 4 1 Rauland RANGER System Planning Parts Required 1 75Q video cable with Phono to Phono connectors (refer to drawing VW2377) or Phono to BNC (refer to drawing VW2376) for RANVFLOP and RANSVHS 1 or Phono to Phono audio cable (refer to drawing VW2385).

Mono audio sources will only need 1 cable. 1 75Q video cable with Phono to BNC connectors for composite out to the video matrix switch input (refer to drawing VW2376) Associated Equipment 1 RANCAGE Card Cage (see “RANCAGE” for more information) 1 RANPS 12 Power Supply 1 Media device (e.g., RANVCR, RANCDI, RANLASER, RANVFLOP, or RANMENU) RANA VDS2 Audio/Video Demultiplexer Module The RANAVDS2 is a stereo Audio/Video Demultiplexer module that takes a combined Video Matrix Switch output signal and converts that signal back to separate audio and video signals. The RANAVDS2 consists of two demultiplexer modules on one PC board allowing two resources to be connected to one RANAVDS2. These stereo audio/video demultiplexer modules are housed in a RANCAGE Card Cage with a 12 VDC at 400 mA power source. They are usually used in conjunction with an operator console or preview monitor (e.g., RANMON13). Parts Required 1 75Q video cable with Phono to Phono connectors (refer to drawing VW2377) or Phono to BNC (refer to drawing VW2376) for RANVFLOP and RANSVHS 1 or Phono to Phono audio cable (refer to drawing VW2385) 2 1 75Q video cable with Phono to BNC connectors for composite out to the Video Matrix Switch output (refer to drawing VW2376) Associated Equipment 1 RANCAGE Card Cage (see “RANCAGE” for more information.) 1 RANPS12 Power Supply 1 Output device (e.g., RANMON13 or RANPCVID). Chapter 3: Baseband, Page 42 7/l l/95 Rauland RANGER System Planning RANSYNCR Sync Generator The RANSYNCR is a black and white camera which produces a sync pulse that is needed to keep the RANGER systems video output in sync when no resource is assigned to a classroom monitor. It mounts on the side of one of the media center equipment racks and requires a 24 VAC power supply. Parts Required 1 VP0266 (24VAC power supply) 2 BNC to Phono 75R video cables (refer to drawing VW2376) Associated Equipment 1 3-conductor wire to interconnect the VP0266 to RANSYNCR RANFT4/RANFT4FM or RANFTl/RANFT7FM Fiber Transmitter Card These transmitter cards convert a coax signal to fiber. The RANFT4 is an AM Quad Fiber Transmitter Card that transfers a baseband audio/video signal from the video switcher over a fiber-optic cable to a classroom (the RANFTI is a single module). In fiber optic based systems one RANFT4 is required for every four outputs (classrooms). While these modules are not required for baseband coax systems, it is possible to have some outputs that are fiber optic and some that are coaxial. The RANFT4FM and RANFTlFM are FM versions of the RANFT4 and RANFTI. Each transmitter mounts in the RANCAGE Card Cage, and requires 12 VDC at 280 mA. Parts Required 1 RANCAGE Card Cage (to mount the RANFT4 or RANFT4FM) 1 RANFBINT TV Interface Box (to mount the RANFRl or RANFR 1FM) Associated Equipment 1 Multimode Fiber-Optic cable 1 BNC to BNC 750 video cable (refer to drawing VW2375) for the RANFT4 RANFR4/RANFR4FM or RANFR 7/RANFR I FM Fiber Receiver Card These receiver cards convert a fiber signal back to coax. The RANFR4 is an AM Quad Fiber Receiver Card that receives a baseband audio/video signal from the video switcher over a fiber-optic cable to a classroom (the RANFRl is a single module). In fiber-optic based systems one RANFRI is required for each classroom that is receiving a fiber Chapter 3: Baseband, Page 43 Rauland RANGER System Planning signal. One RANFR4 is required for every four classrooms that have distributed local origination. While these modules are not required for baseband coax systems, it is possible to have some inputs that are fiber optic and some that are coaxial. The RANFR4FM and RANFRIFM are FM versions of the RANFR4 and RANFRl. Each receiver mounts in the RANCAGE Card Cage, and requires 12 VDC at 340 mA. Parts Required 1 RANCAGE Card Cage (to mount the RANFR4 or RANFR4FM) 1 RANFBINT TV Interface Box (to mount the RANFTI or RANFTIFM) Associated Equipment 1 Multimode Fiber Optic cable 1 BNC to BNC 75L2 video cable (refer to drawing VW2375) for the RANFR4 RANMENU Character Generator VGA to NTSC RANMENU uses an IBM compatible PC to generate and display classroom TV menus for the RANGER system. A PC running RANMENU software interprets live serial data fed from a RAN232 Serial Control Card housed in the RANCC16 Control Card Cage. The data is formatted and sent to the computer VGA video output where it is then converted to a composite NTSC signal via a VGALNTSC scan converter. The video output is then redirected through the method used for video distribution. The RANMENU is comprised of software, interface cable, and a VGA/NTSC converter. Rauland-Borg does not supply a computer. The RANMENU software requires an 8088 or better computer capable of displaying VGA color graphics. The computer requires a license for DOS 3.3 or better, a floppy drive and a RS232 port. No monitor, keyboard, or hard drive is required.
