10.1.1 Use of Kramer Machines
A router may be represented via the Kramer protocol as a maximum of two
machines. Based on the largest supported, 8 level switcher, the levels
correspond accordingly:
Level Machine # Function
1 1 Video
2 2 Video
3 1 Audio
4 2 Audio
5 1 RGB Mute
6 2 RGB Mute
7 1 Audio Levels
8 2 Audio Levels
Parameter Terminology:
Setups - Setup # 0 refers to the present switcher status. Setup # 1 and higher
are the settings saved in the switchers memory, (i.e., those used for store and
recall).
Bi-Directional - specifies a bi-directional command. If the switcher receives
the code, it will perform the instruction; if the instruction is performed, the
switcher will use the same codes for its response.
