    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.

    (connectors) located on the module. Remote Control Panels On the rear panel of the Shasta 1616D there is a 9 pin mini-XLR connector. The mini- XLR connection utilizes RS-485 serial control. The remote control panels have two mini-XLR connectors wired in parallel. The dual connectors allow multiple panels connected to the same router to be looped from one panel to the next.

  • Page 17: Operation

    Connectors associated with the system’s internal control are located on the rear of the routing switcher frames. The Shasta 1616D may be controlled via local or remote control panels or by “Host” commands using the 9-pin RS-232/422 serial port (see the Protocol section of the manual).

  • Page 19: 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 — 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.
  • Page 20 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.

  • Page 21: Leader And Trailer

    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.

  • Page 26 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.

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.

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.
