Create ties
N • Video ties cannot be made between the computer video group and the low resolution video group.
• Program audio ties can be made only to the computer/audio output group (outputs 1 through 6).
• Mixing audio inputs into the output audio using SIS commands requires a complex command. See appendix B,
“Command/Response table for DSP SIS commands”.
• Video and audio ties between the low resolution video input group and the low resolution video outputs group are
always made with the program audio redirected. In such an operation, the switcher automatically ties the audio to an
output in the computer/audio outputs group (outputs 1 through 6) as follows:

If the video is tied to output 7, the audio is tied to output 1.

If the video is tied to output 8, the audio is tied to output 2.

If the video is tied to output 9, the audio is tied to output 3.

If the video is tied to output 10, the audio is tied to output 4.

If the video is tied to output 11, the audio is tied to output 5.

If the video is tied to output 12, the audio is tied to output 6.
• Commands can be entered back-to-back in a string, with no spaces. For example: 1*1!02*2&02*04%4*6$.
• The quick multiple tie and tie input to all output commands activate all I/O switches simultaneously.
• The matrix switchers support 1-, 2-, and 3-digit numeric entries (1*1, 02*02, or 003*003).
N The & tie command for RGB and the % tie command for video can be used interchangeably on the matrix switcher, but
you cannot switch between groups. The switcher returns an X13 error if you try.
N The & view tie command for RGB and the % view tie command for video can be used interchangeably on the matrix
switcher.
