would clear the matrix, and when finished, the following response would be generated:

**OK!!<CR>

This command only clears the crosspoint settings. Any data stored in the setup memory space or the values from the audio gains are not changed by this command. In order to clear or reset these values, the following additional types or clear commands are used:

"Config": Configure Matrix

Request: **CONFIG1234 , oo , ii , l , f1 , f2!!

The Configuration command is protected with a four-digit password (1234 in the above example is a placeholder). The command tells the software the size of the switching matrix, the number of levels and several special functions such as the assignment of levels used for RGB muting and audio gain controls. Like the clear commands explained above, the configure command must begin with the six letters CONFIG, upper or lower case and without spaces between the letters. The present software will accept output values from 1 to 64 (oo) and input values from 2 to 64 (ii) and level values up to 8

(l). f1 and f2 are eight bit (0-255) flag values that can be used to define special system operations. They are normally sent as 000 and 000.

The Config command must have all six arguments in order to affect a change in the router configuration.

Note: changing the router configuration with this command does not change the contents of the non-volatile memory that stores the router’s current state or the contents of the setup registers. Most routers are based on an eight level scheme. When the configuration flags are both set to 000 and 000, the eight levels are used as follows:

Level 1. First video level. If the router is an RGBHV router this level is used for RGBHV.

Level 2. Second video level. This video level can be another RGBHV level or it can be composite video or SDI video, etc.

Level 3. First stereo audio level. The crosspoint hardware will switch left and right channels together as one level.

Level 4. Second stereo audio level. The crosspoint hardware will switch left and right channels together as one level.

Level 5. Used to effect RGB mute switching in conjunction with Level 1. Level 6. No assignment – can be used as a video or audio channel as needed. Level 7. Used in conjunction with level 3 to effect remote control of audio levels.

Level 8. Used in conjunction with level 4 to effect remote control of audio levels.
