SIERRA VIDEO 2 Chapter Video Overview Analog Video Signal Path Overview The Yosemite Family of analog video routing switchers are based on conventional “single stage” crosspoint matrix design. The signal path consists of three elements or modules: 1. Input buffer 2. Crosspoint modules 3.
SIERRA VIDEO Input Buffers Each input buffer consists of a small adapter on the rear of the frame that converts the 75 ohm analog video input into a buffered, very low impedance load (under 5 ohms). Each adapter module contains a 400 Mhz linear circuit. The signal is distributed via a PWA (“Printed Wiring Assembly,” also known as a circuit board) motherboard to the crosspoint matrix portion of the router. The 64x64-frame assembly consists of two sections.
VIDEO OVERVIEW Crosspoint Modules The Yosemite Family analog video switcher uses the newest technology available for the crosspoint matrix. The crosspoint matrix is built using 250MHz high performance surface mount crosspoint arrays. The crosspoint modules in the Yosemite analog video routers are 32x32 switching sub-matrices. The 32x32 matrix consists of eight 16x8 250MHz crosspoint IC’s.
SIERRA VIDEO Input / Output Sub-assemblies Yosemite 6464V/D The 32x32/ 32x24 crosspoint modules are part of a larger plug-in sub-assembly. In the 64x64 system, two 32x32 crosspoint modules are combined with a 32-channel output assembly to constitute a 64x32 subunit. A complete 64x64 7RU system consists of two of these sub-assemblies. A 32x64 system would consist of 32 input buffers installed with only one of the two possible 32x32 crosspoint modules installed in each 64x32 assembly.
VIDEO OVERVIEW Digital Video Signal Path Overview The Yosemite Family of digital video routing switchers are based on the same aforementioned conventional “single stage” crosspoint matrix design. The signal path consists of four elements or modules: 1. Input buffer 2. Crosspoint modules 3.
SIERRA VIDEO As with the Yosemite analog routing switcher, we have based our digital video design on the most up-todate crosspoint technology. The basic switching device is a GaAs (Gallium Arnside) 64x33 1.5Gbps integrated circuit.
VIDEO OVERVIEW Input / Output sub-assemblies The 64x64 digital video router is comprised of two plug-in sub-assemblies. One half of each of these assemblies is a 64x33-crosspoint module. The 64x33 crosspoint module mates with a 33 channel output driver module to complete the sub-assembly. Because the basic crosspoint unit is a 64x33 module, the 96x96 frame is not suitable or cost-effective for digital video. The 128x128 frame has up to four plug-in sub-assemblies.
SIERRA VIDEO Additional Monitoring Outputs As stated in the above paragraphs, the “33rd” output on each sub-assembly is an additional output. The Yosemite 64x64 system is actually a 64x66 and the 128x128 is actually a 128x132. Each of the “33rd” outputs appears on the BNC connectors on the front of the output module assembly, rather than on the rear of the frame. The most common use of the 33rd outputs is service monitoring. In the 64x64 system, the extra outputs are mapped to outputs 65 and 66.
SIERRA VIDEO 3 Chapter Audio Overview Introduction The Yosemite Series Audio routing switchers from Sierra Video are modular for those applications requiring worry-free performance and mission critical reliability. The advanced features and performance set it apart from the competition. These include: Modular configurations expandable by 32 input and/or 32 output increments Compact frame size – 3RU (6464 frame) or 5RU (128128 frame). Hot-swappable I/O boards.
SIERRA VIDEO Frame Configurations Yosemite Audio frames can be ordered in a “mono” or “stereo” mode. Configuration is done at the factory or can be changed in the field (see section on “stereo mode” operation).
AUDIO OVERVIEW Analog Audio Signal Path Overview The Yosemite Family audio routing switcher signal path consists of two modules: an input buffer, and a combination crosspoint module / output driver module. The same two modules are used for both frame sizes: 64x64 and 128x128. Input Buffers Each input buffer module has 32 identical circuits. Yosemite routers are designed to work in broadcast and production facilities, and are compatible with balanced interconnections. The buffers have multiple purposes: 1.
SIERRA VIDEO Crosspoint Sub-assembly Modules The analog audio crosspoint module used in the Yosemite Family is a 128x32 module. The switching integrated circuit (IC) is a HCMOS 16x8 array. Thirty-two of these switching IC’s are arranged to form a 128x32 matrix. Each output bus from the switching matrix feeds a differential output. The output driver provides a symmetrical low impedance output signal.
AUDIO OVERVIEW Digital Audio Signal Path Overview As with analog audio systems described above, the digital audio Yosemite routing switchers use digital modules with the same form factor. Our digital audio frames are available with both asynchronous and synchronous options. These audio AES/EBU compatible routers use high-frequency digital 110 ohm balanced line receivers. They can also be ordered to support S/PDIF single-ended signals with an input/output impedance of 75 ohm.
SIERRA VIDEO Digital Audio Output Accessories 75 ohm Unbalanced Digital Audio By using BNC adapter panels, each of the 110 ohm balanced inputs is converted to 75 ohm unbalanced 1 V P-P nominal input level. The BNC conversion / adapter panel option for the outputs converts each output to BNC connectors with 75 ohm source impedance and nominal 1 V P-P output level. The adapter panels require more space than the routing switcher.
SIERRA VIDEO 4 Chapter Installation Introduction Installation procedures are similar for all frames covered under this manual. However, differences between video frame and audio frame installation exist. Exceptions, if any, have been noted in each of the following paragraphs. Video Frame Rack Mounting Carefully inspect the frame to ensure that there has been no shipping damage. Make sure all modules are seated completely in the frame.
SIERRA VIDEO Vertical Spacing Requirements It is important to provide unrestricted vertical cooling space for all three Yosemite analog and digital video routing switcher frames. Cooling of the Yosemite Family video switchers is by vertical convection cooling. Some models have supplemental cooling fans built into the power supply sub-assemblies. However, the power supply fans are only used for the power supplies and are not intended to promote airflow to the crosspoint and output module assemblies.
INSTALLATION Before Connecting To Video Devices Yosemite video routing switchers have a unique video input design. At the rear of frame, each video input buffer / processing circuit is built in a separate “adapter” See “Video Overview: Input Buffers” for more information. One end of the “adapter” is a BNC connector. The other end of the adapter is a 15 pin D miniature connector.
SIERRA VIDEO Vertical Interval Switching Sync Input The sync input is used to generate vertical interval switching. If no sync is available, the routing switcher will switch at a random point rather than in the vertical interval. There are two BNC connectors labeled “sync” located above the power supply mains and RS-485 control panel connectors on the left of the video frame. These are “looping” inputs. Connect either composite sync or video with sync to either sync input BNC.
INSTALLATION Audio Frame Mounting Carefully inspect the frame to ensure that there has been no shipping damage. Make sure all modules are seated completely in the frame. Each of the Yosemite audio routing switchers described in this manual can be rack mounted in a standard 19" (RU) EIA rack assembly and includes rack "ears" at the ends of the front of the frames. Ventilation Yosemite Family audio frames use horizontal airflow and may be mounted adjacent to other equipment.
SIERRA VIDEO Connecting To Audio Devices Mono Analog Audio Audio sources and destination devices (such as amplifiers or recorders) may be connected to the switchers via a 5-pin latching, removable, terminal block style connectors located at the back of the switchers. Balanced/Unbalanced Analog Audio Connections All audio sources from the routing switcher are balanced audio. Connect the balanced audio to the balanced input of your destination device(s).
INSTALLATION Stereo Analog Audio Yosemite Audio frames can be ordered in a “mono” or “stereo” mode and are pre-configured at the factory. Input and output connections differ when the unit is in the stereo mode. In the mono mode connectors are wired as silk screened on the rear of the router.
SIERRA VIDEO Balanced Digital Audio Yosemite digital audio routers use 25-pin “D” connectors for input and output connection. All inputs are internally terminated with 110 ohms in the digital audio routing switchers. Likewise, all outputs are source-terminated with 110 ohms (55 ohms per line). When balanced digital audio is ordered, Sierra Video supplies a removable screw terminal adapter. Use of the adapter is optional. Each adapter panel connects to 4 of the 25-pin “D” connectors.
INSTALLATION Use of the screw terminal adaptable is optional.

INSTALLATION Unbalanced Digital Audio Since all audio sources and destinations in the routing switcher are balanced, Sierra Video supplies BNC adapter panels when you order unbalanced digital audio. By using BNC adapter panels, each of the 110 ohm balanced inputs is converted to 75 ohm unbalanced 1 V P-P nominal input level. The BNC conversion / adapter panel option for the outputs converts each output to BNC connectors with 75 ohm source impedance and nominal 1 V P-P output level.
SIERRA VIDEO Video Plus Audio Frame Combinations Multiple video frames are frequently combined to form “multi-level” systems. The Yosemite Family can accommodate up to 8 separate control levels. At each of these levels there can be more than one channel of physical routing switchers. Frequently, component video (YC, RGB, etc.) will share the same control level. The same may be true of multiple analog audio channels.
INSTALLATION Default Yosemite Settings Before Sierra video ships a Yosemite, the routing switcher system is set with critical initial settings, unless otherwise specified at the time of order. These settings allow the user to install the system and have it quickly operational. Basic Size The number of sources, destinations, levels, and physical layers are the first items to be programmed.
SIERRA VIDEO Mapping Virtual & Physical Tables Virtual-to-physical mapping tables, used in software version. 5.01 and later, are configured for one-to-one mapping (e.g. source 1 is mapped to physical input 1) on all levels. An exception is made in the case of partially-stuffed routing switchers with holes. In these routers, the mapping is set to skip over the holes. This creates a discrepancy in the mapped input/outputs and the silk screened numbers on the rear of the frame.
INSTALLATION Control Processor DIP Switches S1 S2 S3 S4 505150 Control Processor Board S2 S1 504001 Control Processor Board Note: Changing any Dip Switch causes an automatic reset after a few seconds DIP Switch settings sometimes vary according to the version of software being run in the processor board. **The software version installed the 505150 processor is labeled on U14 and U24 of the processor module.
SIERRA VIDEO Dip Switch Activation Yosemite DIP Switch devices have eight numerically marked switches. DIP Switch devices are labeled as S1, S2 or Switch 1, Switch 2. To activate a function or feature, locate the DIP Switch that controls that action in the tables below. Move the DIP Switch lever to the “ON” or “OFF” position specified in the table. For most cases, the silk-screened numbers on the device denote “OFF”, differing from the opposite silkscreened “ON”.

SIERRA VIDEO 5 Chapter Operation Control System Overview The Yosemite Family’s three port control system incorporates many powerful features, while retaining control compatibility with many leading third party control systems and with most earlier generation SV routing switchers. The control systems uses an intuitive interface for routing switcher control and configuration, pass wording, salvo setup, multiple input/output configuration and name configuration.
SIERRA VIDEO Port 1 (Terminal Port) Yosemite routing switchers have two 9-pin RS232 connectors that allow you to control the switcher using a standard personal computer or other external devices (such as Creston or AMX). Port 1 is shipped with Terminal protocol mode set as default. A 9-pin connector labeled “RS232/422 Port 1”, located above the sync input reference mains, is used for a simple terminal (V=T100 emulation capability).
OPERATION Port 2 (Host Port) Port 2 is shipped with Host protocol mode set as default. A 9-pin connector labeled “RS232/422 Port 2”, located above the sync input reference mains, follows an ASCII protocol control.
SIERRA VIDEO Changing Ports 1 & 2 Between Host & Terminal To change a port setup, send special character sequences to the port (or type this sequence in at a terminal). See DIP SWITCHES for more information. To switch Port 1 to Host protocol: 1. Turn off the switcher and remove the serial control module (504001, 505150) 2. Turn off Dip Switch 5 on the 504001’s S2; turn on Dip Switch 4 on the 505150’s S3. 3. Reinstall the serial board and turn power back on. The serial port now uses the Host protocol.
OPERATION Port 3 (RS-485 Control Panels) Yosemite Family video routing switcher frames have four male 3-pin connectors labeled “RS-485 Control Panels” on the rear. Yosemite Family audio frames have just two male 3-pin connectors on the rear. Each Yosemite control panel has two parallel connectors. Four RS-485 Control Panel Connectors Located on the Rear of the Frame The maximum system cable length is 2,000 feet (310m) when the RS-485 network operates at the higher speed of 31.25K baud.
SIERRA VIDEO 6 Chapter 505150 Processors Introduction Two types of control processors can be used to control the Yosemite routing switcher. The Sierra video 505050 module is the most popular in the Yosemite line. This control processor is installed in a video frame and can control the routers interconnected to the video frame. If Yosemite Family video frames are not ordered in a system, a Sierra video 504001 Tahoe controller module is installed in one of the audio frames.
SIERRA VIDEO Processor Health Monitoring and LEDs Processor LEDs Each processor monitors its own health and displays a healthy/sick indication on the processor edge LEDs. Two LEDs indicate the health of the processor on which they are located, two LEDs indicate the health of the other redundant processor, and two offer other important information. Both processors continually monitor the following expected conditions within the processor: Presence of vertical sync interrupt.
505150 PROCESSORS LED Diagnostics While the Yosemite Family video routing switchers are in operation LEDs indicate the system’s performance. There are six colored LED bulbs located on the edge of the processor, and ten DIP Array LEDs located in U1. These LEDs reveal possible problems and can help you troubleshoot the routing switcher performance.
SIERRA VIDEO Diagnostic Startup Sequence When the switcher is powered up or resets for any reason (as when a DIP Switch is changed), it performs a series of self-tests, signaling progress using the DIP Array and Colored LEDs on the 505150 processor board. The startup self-test sequence is fast but provides important diagnostic checks.
505150 PROCESSORS Terminal Diagnostics The results of the last startup self-test can also be viewed using the diagnostics screen in the terminal protocol. Enter “D” to display this screen. A startup self-test result code will be displayed as an 8-bit number: ABCDEFGH. Bits that are 1 indicate failures.
SIERRA VIDEO System Size and Terminal Command A routing switcher with a 505150 process has a maximum matrix size of 128 sources, 256 destinations, and 8 levels while one with a 504001 has a maximum matrix size of 128 sources, 128 destinations, and 8 levels. The actual size is set with the TyLinx Pro software program (see TyLinx Pro manual for details), terminal protocol control/W “U” subcommand or the host protocol “G ROUTER_INFO” command.
505150 PROCESSORS Non-volatile RAM The control processor board contains battery-powered RAMS, which are used to store the crosspoint matrix state, mapping information, salvo presets, source/destination/input/output/level names, control panel configuration, source/destination restrictions, output lockouts, and other non-volatile information. Any information stored in the non-volatile RAM remains there when the switcher is powered down.
SIERRA VIDEO Redundant 505150 Processors Introduction The Yosemite Family supports the use of redundant processors. A system with this option has two different control processors. At any given time, one of the processors is the master and the other is the standby processor. The master processor is the one that controls the system.
505150 PROCESSORS Preferred Master Switch A requirement of the two processors is to set one CPU as the master processor and the other CPU as the slave. The setting is made with DIP Switch S1-1. It is essential that S1-1 be set opposite on the two processors for redundancy to function properly. This DIP Switch setting determines which processor will become the master processor when both processors are powered on at the same time.
SIERRA VIDEO Processor Synchronization The “usual state of affairs” for redundant processors is that both processors always power up at the same time, and continue to operate until power down. In that situation, the standby processor always is up-todate with regard to any router configuration information that the master processor has received (crosspoints, salvos, panel’s settings, input/output/level names, etc).
505150 PROCESSORS In Terminal Mode, this lapse could cause potential problems because the user often stays in submenus longer. Because the standby processor starts up in the main terminal menu, it is unable to sync itself to a submenu and any information the user is trying to submit will be lost.
SIERRA VIDEO Redundant Processor Status and Terminal “T” Screen Terminal protocol provides a way to examine the status of the redundant processors. This is done by entering “T” to display the redundant processor status screen. See Terminal Protocol. Remember that the screen is being produced by the master processor, including controlling the display of terminal protocol screens.
SIERRA VIDEO 7 Chapter 504001 Processors Introduction Two types of control processors can be used to control the Yosemite routing switcher. If Yosemite Family video frames are not ordered in a system, a Sierra video 504001 Tahoe controller module is installed in one of the audio frames. All Yosemite audio frames have a module position pre-wired for a 504001 processor. Dual or single processors can also be mounted outside of the Yosemite audio frames in the 1 rack unit (1.75”) processor frame.
SIERRA VIDEO LED Diagnostics While the Yosemite Family routing switchers are in operation LEDs indicate the system’s performance. On the 504001 processor there are ten DIP Array LEDs located in LED1. These LEDs reveal possible problems and can help you troubleshoot the routing switcher performance. 504001 LED Indicators to the right of DIP Switches LED LED1 LED2 LED3 LED4 LED5 LED6 LED7 LED8 LED9 LED10 Meaning Terminal receive data.

504001 PROCESSOR Diagnostic Startup Sequence When the switcher is powered up or resets for any reason (as when a DIP Switch is changed), it performs a series of self-tests, signaling progress using the DIP Array on the 504001 processor board. The startup self-test sequence is fast but provides important diagnostic checks.
SIERRA VIDEO Startup Self-test Results The results of the startup self-test that was done when the routing switcher started up the last time can be displayed using the diagnostics screen in terminal protocol. Enter “D” to display this screen Refer to Terminal Protocol section for more information. A startup self-test result code will be displayed as an 8-bit number: ABCDEFGH. Bits that are 1 indicate failures.
SIERRA VIDEO 8 Chapter Communication Protocol Introduction The protocol uses the 7-bit ASCII character set, usually sent over an RS232-C or RS422 serial link — 9600 bps is recommended with 8 data bits and no parity. The protocol is compact, with few characters required to cause switch changes to occur. It is also human-readable and thus easy to understand and use.
SIERRA VIDEO ASCII character whose code is less than the SPACE character (includes all control characters and the SPACE character) and the DEL (ASCII 7F) character. Alphabetic characters within the command string may be in either upper-case or lower-case letters. The router always sends upper case characters, except for character strings such as input, output, and level names, which may have lower case characters in them.
SPECIFICATIONS The following is the set of commands available for sending to the router, a subset of which may be implemented in any given routing switcher.
SIERRA VIDEO “R”: Router Reset Use this command to force the routing switcher to reset, by sending it the command "RESET". If an administrator password has been set (using the “G ADMIN_PASSWORD” command described later in this document), then the password must be sent in a “K” message prior to sending this command, else this command will generate an error.
SPECIFICATIONS “L”: Matrix Size and Level Names Inquiry The command "L" requests that matrix size (Nout, Nlvl, Nin) and level name information (lvl1, lvl2, etc.) be returned to the host. The information is sent as a string of characters.
SIERRA VIDEO ** X12,4,2 X-,4,3 X0,4,4 !! giving the status of levels 2, 3, and 4 (level 1 presumably not being a single-output-per-input level). Note that on level 3 the ë-ë (dash) indicates that the input is disconnected, and on level 4 the 0 indicates that the connection to the input is either unknown or that input does not exist or is not available on that level. If the router has only one level, or if all levels are connected the same, it might instead use the Y command.
SPECIFICATIONS “K”: Set Password The command "K" is followed by a password, which may be 0 to cancel the previous password, thus causing no password to be specified, or, it may be a value between 1 and 9999 to supply a password, which remains in effect until another password (or password 0) is supplied in another “K” command.
SIERRA VIDEO controlling devices will honor the system. A dedicated hacker can always hack into the system if he chooses. Note, however, that the server in a client/server relationship can provide a great deal of added security for the system, forcing the correct “M” command to be sent each time, and filtering out bogus “M” commands received from clients. When the router receives an “M” command in a command string, it echoes the same “M” command in its response.
SPECIFICATIONS To turn off output change reporting, use the command: **U0!! The difference between an argument value of 1 versus 2 has to do with the response generated by the router when it receives a crosspoint connect command (“V”, “W”, “X”, “Y”, or “Z” command).
SIERRA VIDEO For example, the command: **W0,8,3,7!! says that connections are to be made on all levels: from input 8 to output 1, input 3 to output 2, and input 7 to output 3. An input number of 0 means the output connection is to be left unchanged. An input number of ë-ë (dash) means the output is to be disconnected. If the router does not support disconnected outputs, the output connection will be left unchanged.
SPECIFICATIONS An input number of 0 means the output connection is to be left unchanged. An input number of ë-ë (dash) means the output is to be disconnected. If the router does not support disconnected outputs, the output connection will be left unchanged. Any input or (implied) output number may be specified as long as it exists on at least one level. No connection will be made on any level on which an input or (implied) output number does not exist.
SIERRA VIDEO “P”: Preset a Salvo The command "P" is used to set up a salvo, which is a series of connect commands for later execution with the "T" command. It must be followed by a register letter from A to Z or a register number from 1 to 256 giving the register into which the connect sequence is to be stored, followed by zero or more connect commands (V, W, X, Y, or Z), followed by a "~" (tilde) character. Registers A-Z are the same registers as 1-26.
SPECIFICATIONS not the administrator password. Any use of a password larger than 9999 also fails. In any of those cases, the output lock status remains unchanged and an error response is generated. The “B” command response will indicate that the output still has the same lock state as before.
SIERRA VIDEO “F”: Field Delay The command "F" is used to specify the delay between the time a crosspoint change request is received by the router and the time the crosspoint switch actually occurs. It must be followed by a number giving the number of video fields of delay desired. If the number is smaller than the smallest delay that the router can handle, the smallest delay is used instead. If it is larger than the largest delay the router can handle, the largest delay is used instead.
SPECIFICATIONS The fielddelay value applies to the entire router, not just to the control port on which the “F” command is received. It is therefore recommended that a single value be settled on for the fielddelay value, rather than changing the value constantly depending on needs. Once changed, the router records the value in non-volatile memory and uses it each time it is powered up, so it is only necessary to change it one time.
