  • Page 12: Sequoia Family Overview

    Sequoia Family Overview Introduction The Sequoia Family of routers provides a high-end multi format solution for every routing requirement. Broadcast, Post Production, Government and large-scale presentation customers can take advantage of Sequoia’s ability to mix signal formats within the same frame. With 16 levels of control standard, the system controller can provide any Sierra Video System router with complete control.

  • Page 13: Frame Configuration

    INTRODUCTION Frame Configuration Each frame can be configured in a wide variety of sizes. The building-block modules are incremental, based on: Frame size Different crosspoint modules Input and Output buffer modules Flexibility in frame size, combined with an incremental module building block design, allows for a large array of configurations that will match your requirements.

Exceptions, if any, have been noted in each of the following paragraphs. Rack Mounting Carefully inspect the frame to ensure that there has been no shipping damage. Make sure all shipping material is removed from the router frame.

  • Page 18: Connecting To Video Devices

    SIERRA VIDEO SYSTEMS Connecting To Video Devices Video input and output devices (such as monitors or recorders) may be connected to the routing switchers through the BNC type connectors located on the back of the unit. Keep in mind that the output signal format will be the same as the input signal.

  • Page 19: Control Port 1 (By Default The Terminal Port)

    This port can be either RS-422 or RS-485 using a 9 pin D connection. Connections to the 9-pin are shown in the table below. “Transmit” and “Receive” are names used by the Sierra Video Systems router. For connection to an external PC or other controlling device use the opposite names.

  • Page 20: Control Panels

    There are four male 3-pin connectors labeled "CTL PNL RS-485" (for Control Panel) on the back of the processor frame. Each Sierra Video Systems control panel has two connectors. The connectors are in parallel for daisy chaining multiple control panels.

  • Page 21: Sync Input

    INSTALLATION Sync Input The “BNC” sync input is used to generate accurate vertical interval switching. If no sync is available, the router will switch at a random point rather than in the vertical interval. There are three BNC connectors labeled Ref 1, Ref 2, Ref 3. These are "looping" inputs. Connect either composite sync or video with sync to any of the reference inputs.

  • Page 22: Control Processor Dip Switch Settings

    SIERRA VIDEO SYSTEMS Control Processor DIP Switch Settings Your switcher has been configured at the factory for the settings you are most likely to need. However, if you want to configure the switcher differently, you can do so by setting the switches located on the processor board (behind the front panel).

  • Page 23: Router Crosspoint Control

    INSTALLATION DIP switch settings for software versions 11.35 or newer Router Crosspoint Control When multiple frames, audio and/or video, are combined into the same control system, all of the frames must be installed so that the high-speed control interconnect system is limited in length. The total length should not exceed 25 feet (7.6 m).

  • Page 25: Theory Of Operation

    Tahoe and Shasta family products and is supported by multiple control and automation companies (see Chapter on Communication Protocol). A wide variety of control panels are available, operating on the standard Sierra Video Systems RS-485 control panel network using a simple twisted pair of wires. Control panels can be located up to 5,000 feet (1,500 m) away from the frame.

  • Page 26: Led Definitions

    SIERRA VIDEO SYSTEMS makes sense to reinitialize the non-volatile RAM. To accomplish a re-initialization, turn on DIP switch S1-8, power up the router, power it down, and turn off S1-8. If for any reason a customer decides to do this, it is highly recommended that they record as much of their router setup data as possible, using the terminal port to access the data.
  • Page 27 THEORY OF OPERATION Preferred Master Switch A requirement of both processors in a two processor (redundant) system is that they are set so that one is the preferred master processor and the other is the preferred standby processor. This setting determines which processor will become the master processor when both processors are powered on at the same time.
  • Page 28 SIERRA VIDEO SYSTEMS When it is necessary to remove a processor from the router, the master processor should not be removed while the synchronization is in process, i.e. while Yellow LEDs are flashing. If it is removed, the standby processor will take over with possibly out-of-date configuration information.
  • Page 29 THEORY OF OPERATION protocol displays a message to the user that a standby processor is now available, and asks him to press the “Control/C key combination”. After Control/C is pressed, the router configuration screen is displayed. This serves to synchronize both processors to the same terminal screen. Processor Health Monitoring and LEDS Each processor monitors its own health, as well as that of the other processor, and displays a healthy/sick indication on the processor edge LEDS.
  • Page 30 SIERRA VIDEO SYSTEMS If the standby processor has determined that it is “sick” (it is flashing its LEDd), it will refuse to take on the job of master processor, even if the other processor is not present. A processor can only be master processor when it thinks itself is okay.

    GRIP software or generic terminal software running on an IBM compatible PC. The de-scrambling process is different for each and every Sequoia router configuration. As part of the circuit description and schematic diagrams for the crosspoint modules, Sierra Video Systems include the de-scrambling lists for each module.

  • Page 33: Digital Video Signal Path Overview

    THEORY OF OPERATION Digital Video Signal Path Overview The Sequoia Series digital video routers are based on a conventional "one stage" (for compact routers up to 128X128 in size) or “two stage” (for expandable routers up to 512X512 in size) crosspoint matrix design.

  • Page 35: Operation

    To change to RS-422 see the “Installation” section of this manual. Connections to the 9-pin are shown in the table below. “Transmit” and “Receive” are names used by the Sierra Video Systems router. For connection to an external PC or other controlling device use the opposite names.

  • Page 36: Host Mode

    SIERRA VIDEO SYSTEMS Connection to PC; 2 RX 2 TX 3 TX 3 RX 5 GND 1 , 9 GND Host Mode Sequoia series routing switchers have several 9-pin RS-232 connectors that allow you to control the switcher using a standard personal computer or other external devices (such as Creston or AMX).

  • Page 37: Communication Protocol

    SIERRA VIDEO SYSTEMS Chapter Communication Protocol Introduction The protocol uses the 7-bit ASCII character set, usually sent over an RS232-C or RS422 serial link — 115.2K Baud is recommended with 8 data bits and no parity. The protocol is compact, with few characters required to cause switch changes to occur.

  • Page 38: Generic Protocol

    SIERRA VIDEO SYSTEMS Generic Protocol Commands are sent to a routing switcher in a group called a command string. A command string can contain zero or more commands, limited only by the size of the receive buffer of the router, whose size depends on the particular router model.

  • Page 39: Leader And Trailer

    GENERIC PROTOCOL After the command string has been executed, the routing switcher returns the string " OK " (with a single space character before and after the word "OK"), followed by the trailer (!!) and a CR (carriage return, ASCII 0D) character, to the host. This indicates that the command has executed successfully.

  • Page 41 GENERIC PROTOCOL “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.
  • Page 42 SIERRA VIDEO SYSTEMS “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. The first characters are a space followed by "L", some optional values described below, then the number of outputs...
  • Page 43 GENERIC PROTOCOL “N”: Input Status Inquiry The command "N" requests that matrix status information for a single input be returned to the host. This command is only useful on those router levels that allow an input to be connected to at most one output.
  • Page 44 SIERRA VIDEO SYSTEMS This indicates that output 1 is connected to input 12 on level 1, and that output 2 is connected to input 2 on level 1. The number of digits used for each number is generally the maximum number of digits ever required for that particular switcher.
  • Page 45 GENERIC PROTOCOL requests that password 1777 be stored as the current password for remote address 197. The command: ** M197 Y7,9 !! requests that output 7 be connected to input 9, using the password stored for remote address 197 as the output lockout override password. The take will succeed if output 9 is either not locked or is locked with password 1777.
  • Page 46 SIERRA VIDEO SYSTEMS ** M139 OK !! If remote address 13 later sends the command: ** M139 Y8,27 !! to request that output 8 be connected to input 27, the router would check to see if output 8 has been locked. If so, the router compares the password of remote address 139 (which has previously been set to 96643) to the password that was used to lock output 8.
  • Page 47 GENERIC PROTOCOL **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). For example, suppose the router sends the following crosspoint connect commands in a single command sequence: ** Y1,18 Y8,34 !! If U1 is in effect, the response to this command will be:...
  • Page 48 SIERRA VIDEO SYSTEMS “W”: Connect Outputs The command "W" is used to request that a connection be made. It must be followed by a level number, a comma, and a comma-separated list of input numbers, one for each output, up to the number of outputs in the router.
  • Page 49 GENERIC PROTOCOL “X”: Connect Crosspoint Use command X to request that a connection be made. It must be followed by an output number, a comma, an input number, a comma, and a level number. For example: **X8, 3, 2!! This string says that a connection is to be made between output 8 and input 3 on level 2. If the level number is specified as “0”, this means that the connection is to be made on all levels (AFV).
  • Page 50 SIERRA VIDEO SYSTEMS If “U2” is in effect (see “U” command), the response will include one or more V, Y, or X commands to report the new status of the outputs. The response will be the same as if “O”...
  • Page 51 GENERIC PROTOCOL “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 "~"...
  • Page 52 SIERRA VIDEO SYSTEMS If the “password” and “lock” arguments are both 0, this is a query for lock status of the specified output. A “B” command is sent to report the lock status. If the “password” argument is not 0, this is a request to change the lock status of the specified output.
  • Page 53 GENERIC PROTOCOL indicating that output 21 is NOT locked. Or, the response might be: ** B21,6741,1 OK !! indicating that output 21 is locked with password 6741. To clear this lockout: ** B21,6741,0 !! To lock output 96 using password 439: ** B96,439,1 !! If successful, the response would be: ** B96,439,1 OK !!
  • Page 54 SIERRA VIDEO SYSTEMS The delayfields argument of this command takes into account the hardware delay. So, if a router has a minimum delay, including the hardware delay, of one full field, as described in the previous paragraph, then a delayfields value of 1 causes this minimum delay to be used. A delayfields value of 0 will also cause this minimum delay, because the router uses its minimum if a smaller value is specified.
  • Page 55 GENERIC PROTOCOL This says that input 5 is to be connected to output 1 on all levels and input 6 is to be connected to output 2 on level 3, after a delay of 5 fields from the beginning of the field that follows receipt of the “!”...
  • Page 56 SIERRA VIDEO SYSTEMS Some “G” commands may initiate an action or report the occurrence of an event, instead of querying or changing a router parameter. Commas are used to separate arguments in the “G” command. Space characters should not appear within the “G” command arguments, except when they appear within strings.
  • Page 57 GENERIC PROTOCOL out which variables a particular router actually supports. Refer to documentation for each router for a description of the variables. A variable value is typically an unsigned decimal number, but may also be a signed decimal number. The “G VARQRY” command can be used to determine the allowed range of values.
