These voltage levels can be set using analog outputs from different control systems or spare dimmer control outputs.
7.5 MANUAL LOOP CONTROL
Loop control is used when multiple units of the MX2406RM are connected to form a single switcher. When the input channel button is pressed the loop control pin is internally grounded and the MX2406RM Switcher selects INPUT 4 as the default input.
In this configuration, loop control pin 6 on the 9 pin D connector is connected to the same pin on all switchers.

MX2406RM
The loop control pin has an internal 100k resistor to +5volts. This limits the number of switchers that can be looped to a maximum of 10 switchers that can be daisy chained together using this method.
More specifically, the output of one switcher is connected to INPUT 6 of the next switcher. Once loop control is enabled these switchers will automatically switch video signals to the output of the second switcher through INPUT 6. Keep in mind that you are always going to have one less input than the total number of inputs available on all switchers. The figure above is for an

When multiple MX2406RM units are connected to form a single switcher and
If you want to make 11 by 1 switcher using two 6 by 1 switchers, the following commands need to be used to control these switchers:
