Sierra Video Systems Factors Affecting Quality of Results There are many factors affecting the quality of results when signals are transmitted from a source to a destination. Signal cables — Use only the best quality cables to avoid interference and degraded signal quality and elevated noise levels. Sockets and connectors of the sources and destinations — Use only the highest quality, since "zero ohm" connection resistance is the target.
Sierra Video Systems Installation 2 Chapter Introduction The Shasta 88D routing switcher consists of two pieces, the electronics frame and a separate in-line power supply. The electronics portion of the 88D is contained on a single plug-in circuit board which plugs into a 1RU frame. 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.
Sierra Video Systems Connecting To Video Devices Video sources 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 that of the input signal format. All signal connections that use more than one cable interconnecting between devices should be of equal timing length (example: cables between a camera and the switcher should have the same time delay).
Shasta 1616D Sync Input There are two BNC connectors labeled "SYNC". This is a "looping" input for sync referencing. Connect either composite sync or video with sync to either BNC. If desired, use the second BNC to loop the signal to another device. If the loop is not used, terminate the second BNC with 75 ohms. If no sync is available, the routing switcher will switch at a random point rather than during the vertical interval of the reference signal.
Sierra Video Systems Operation 3 Chapter Control System Overview The Shasta Family’s control system incorporates many powerful features, while retaining control compatibility with many leading third party control systems and with earlier generation SVS routing switchers. The control system uses an intuitive interface for routing switcher control. A variety of control panel styles are available including singlebus, X-Y, and simple keypad.
Sierra Video Systems Communication Protocol 4 Chapter 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 Systems The protocol uses only 7-bit ASCII characters. The 8th bit of received characters is treated as if it is 0. Within the command string, certain ASCII characters may be present and are ignored: any 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.
Shasta 1616D Leader and Trailer The simplest possible command string would be “**!!” which consists of the leader and trailer characters but no command between them. This command string would generate the response “**OK!!” followed by “CR”. This can be useful for verifying that the serial link to the switcher is operational. 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 Systems “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.
Shasta 1616D For example, the command: **L!! might return the following string: ** L64,3,32,VIDEO~AudioL~AudioR~~ OK !! indicating that the router has 64 outputs, 3 levels, and 32 inputs, and the levels are named "VIDEO", "AudioL", and "AudioR". “O”: Output Status Inquiry The command "O" requests that matrix status information for a single output be returned to the host. The status information is sent as a “Y” command or a “V” command or as a sequence of L “X” commands, where L=number of levels.
Sierra Video Systems “S”: Status Inquiry Use command S to request that status information be returned to the host. The status information is sent as a string of L x O substrings, where L = number of levels and O = number of outputs. Each level/output combination generates a single substring of status. Thus, a 21-level 16 output router would generate 2x16 = 32 substrings of status command output. The length of each substring depends on the size of the particular switcher involved.
Shasta 1616D receives a protected command (one which requires use of a password) from a remote address, it compares the current password for that remote address with the password required to execute the protected command. Protected commands consist of many of the “G” commands that change router configuration, as well as take and salvo trigger commands when the output to be taken is locked.
Sierra Video Systems Normally the server will assign remote addresses to its clients. However, it should always provide a way to send these addresses to the client, because the client needs to know its address in order to know how to interpret some responses. By simply passing each “M” response command received from the router back to the client, the server can let the client know what its address is.
Shasta 1616D and then sometime later, perhaps up to several seconds later, the crosspoint change reports will be sent as separate command sequences for each output: ** Y1,18 !! ** Y8,34 !! On the other hand, if U2 is in effect, the response to the original crosspoint change command sequence will be: ** Y1,18 Y8,34 OK !! and no additional crosspoint change reports will be sent because they already HAVE been sent.
Sierra Video Systems mapped to a physical connector (on virtual-mapped routers) on one or more levels, those levels are simply not changed. 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” commands were issued for the outputs immediately following the “W” command. No response is generated if this command is being used to define a salvo.
Shasta 1616D “D”: Delay vertical sync intervals The command "D" is used to delay before continuing execution of the commands that follow. It must be followed by a number giving the number of vertical sync intervals by which to delay. If the number is 1, the delay will be to the VERY NEXT vertical sync interval. If the number is 0, no delay occurs. The number must be no larger than 255.
Sierra Video Systems Only supported connect commands (those connect commands whose command letters appear in the "I" command response) may follow the register letter up to the tilde character. The connect commands do not take effect until the register is triggered using the "T" command below. The maximum allowed number of connect commands is determined by the particular router.
Shasta 1616D the administrator password in a “K” command, that will not permit the device to reroute locked outputs (but it can use the administrator password to unlock locked outputs using the “B” command). Output lockouts apply on all levels. On virtual-mapped routers, a level may be left out of a lockout by making sure the level is unmapped for the destination being locked.
Sierra Video Systems A typical router will have a minimum delay that is between 1 and 2 fields. Suppose a crosspoint command is received just before a vertical field mark. The software may be able to prepare the crosspoint data and send it to the hardware when that vertical field mark occurs, but the hardware itself typically has a one-field delay in it, so the soonest that such a crosspoint would switch would be one field (plus a little) from when it was received.
Shasta 1616D later devices’ input value as being the one in effect. To prevent this scenario, we recommend that an appropriate fielddelay value be chosen, set, and left alone. Here is an example of an “F” command: ** F5 Y1,5 X2,6,3 !! 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 “!” character.
Sierra Video Systems 5 Chapter Troubleshooting Introduction NOTES: If the output signal is disturbed or interrupted by electromagnetic interference, the signal should return and stabilize when the interference ends. If not, turn the power switch off and on again to reset the switcher. If the following recommended actions still do not result in satisfactory operation, please consult your Sierra Video Systems Dealer.
Sierra Video Systems Video Signal Problem No video at the output device, regardless of input selected. Video level is too high or too dim. Remedy Confirm that your sources and destination device are powered on and connected properly. Video signals connected to the input of the switcher should be of an identical signal format as the output of your source. Video signals at the output of your switcher should be of an identical signal form required by your video monitor or recorder.
Shasta 1616D Control Problem Remedy No control of Matrix Switcher from PC software Confirm the correct wiring of the connecting cable. Be sure to use the serial adaptor provided if using a standard PC serial cable. Confirm that all Dip Switches on the control processor are set properly. See Dip switch settings on page Error! Bookmark not defined.. Confirm that the baud rate of your computer COM port is set to the same as that of your Matrix Switcher (9600-Baud recommended).
