In some cases, these frames may be configured with no audio or less outputs. Consult the rear panel serial number and model number to verify your order and product.
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 2 Chapter Installation Introduction Installation procedures are similar for all four frames covered under this manual. 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. Important; Rear-mounting brackets must be installed prior to installation of the router into a rack.
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).
VS/DE SERIES Audio Adjustments Unity gain is set at the factory. Audio gain is adjusted via a menu option. See “Menu Items” in the Operation section Chapter 3. Audio gain can also be adjusted via the 9 pin serial port using the SVS GRIP program (refer to the GRIP manual), or SVS serial protocol (see the communication protocol section of this manual for details). Audio Follow Video and Breakaway Audio Configurations Video and Audio signals are switched by separate crosspoint modules.
SIERRA VIDEO SYSTEMS Sync Connector There are two BNC connectors labeled "VID. REF IN". 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.
VS/DE SERIES Names Source, Destination, Salvo, and level names can be applied using two methods. Names can be applied using the GRIP program (See the GRIP manual for details on naming), or names can be applied using the serial port (See the Generic Protocol section of this manual). Salvos A Salvo is a group of Sources and Destinations that are stored in the routing switcher and switched by a single “Salvo Take” command.
SIERRA VIDEO SYSTEMS 3 Chapter Operation Introduction The purpose of a routing switcher is to switch any of the inputs (source) to any one of the outputs (destination). Any input can be connected to any or all outputs but each output can only be connected to a single input. Control remains the most important component of your new system. The standard local control panel empowers full control of the routing switcher while allowing external RS-232 control via the serial port.

SIERRA VIDEO SYSTEMS Select System Parameters – Selecting system parameters allows access to adjust various settings of the 9 pin serial port and control panel port on the rear of the router. A “Disable Front Panel” option is also contained in this menu. Adjust Audio Gains – This menu path allows the input gain to be adjusted. The input gain may be changed from –10db to +20db in .5db to 1db increments. The output gain can be changed from output mute, -61db to +15db in .5db to 1db increments.
VS/DE SERIES Control via 9-pin Connectors The 9-pin connectors allow you to control the routing switcher via an external computer. On some switcher models, the serial port can be changed internally for RS422 configuration (RS232 is factory configuration). Each routing switcher model has one port and it is labeled on the back panel as “RS232/422 Control” (refer also to the illustrations of back panels shown in Chapter 1): Connection to the RS-232/422 port is made using a standard 9 pin (pin to pin) cable.
SIERRA VIDEO SYSTEMS Host Mode The 1616VS matrix switchers have one 9-pin RS232 connector that allows you to control the switcher using a standard personal computer or other external devices (such as Creston or AMX). The switchers are shipped in the “Host” mode but can be changed to the “Terminal” mode by the following procedure: ? Connect a terminal to the serial port and send the following command: **HOST0!! The port now uses the terminal protocol.
SIERRA VIDEO SYSTEMS 4 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 SYSTEMS If a leader character (**) is encountered within the command string being processed by a router, the command string up to that point is discarded and a new command string is expected. This ensures that a router will always act on a complete command string sent to it, even if the previous one was never completely received.
VS/DE SERIES ** XXX !! might generate this response from the router: ** ERROR Syntax: No Number:XX !! The descriptive string always ends with a colon and up to three characters from the command string that caused the error. Generally, the error can be assumed to have occurred just before these characters Leader and Trailer The simplest possible command string would be “**!!” which consists of the leader and trailer characters but no command between them.
SIERRA VIDEO SYSTEMS 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.
VS/DE SERIES “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.
SIERRA VIDEO SYSTEMS ** 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.
VS/DE SERIES “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.
SIERRA VIDEO SYSTEMS before the “K” command in the same command string as the “K” command. The password that is set remains in effect until another “K” command is received from the same remote address. It would be used to establish a password for a remote address, to be used for such things as locking and unlocking outputs and modifying the router configuration.
VS/DE SERIES 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. For example, the command: ** M139 K9664 !! establishes password 9664 as the password for remote address 139.
SIERRA VIDEO SYSTEMS ** 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. The U2 mode of operation is generally more convenient because it produces more immediate feedback to the controlling device that is sending a crosspoint change command.
VS/DE SERIES “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).
SIERRA VIDEO SYSTEMS “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.
VS/DE SERIES 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.
SIERRA VIDEO SYSTEMS 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. As with all router configuration parameters, the output lockout data is stored in non-volatile storage and thus is retained across router power-ups.
VS/DE SERIES 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. If the command were received towards the beginning of a field rather than the end of a field, the delay would be closer to two fields. Industry parlance is to call this a one-field delay, because only full fields of delay are counted. The delayfields argument of this command takes into account the hardware delay.
SIERRA VIDEO SYSTEMS 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.
VS/DE SERIES When a “G” command is sent by the router, it will always include this space, but the space is optional when sending a “G” command to the router. Character string arguments are delimited on both sides by a tilde (‘~’) character. Generally character strings may contain any printable ASCII character except tilde, asterisk, and exclamation. Every “G” command must be terminated with a tilde (‘~’) 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. 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.
VS/DE SERIES Audio Signal Problem No audio at the destination device, regardless of source selected Remedy ?Confirm that your sources and destination device are powered on and connected properly. Audio signals connected to the input of your switcher should be properly wired from the output of your source. Audio signals connected to the output of your switcher should be properly wired to the input of your destination device.
SIERRA VIDEO SYSTEMS Switching Malfunctions Problem The switcher succeeds in switching a number of sources then fails to switch one. Remedy Malfunction in the particular source or cable assembly. NOTE: The most common failure mode in transferring the signal of an audio source is a break in the connecting wire. ?Disconnect the source from a channel that is switching successfully and connect the suspect source to it.
