SWITCHERS
The loop control pin has an internal 100k resistor to +5volts. This limits the number of switchers looped to a maximum of 10 switchers that are 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

If you want to create an 11 by 1 switcher using two 6 by 1 switchers, the following commands must be used to control these switchers:
Input 1 through Input 6 | [OUT01] |
Input 7 through Input 11 | [OUT02] |
This will setup each switcher as a different output number. To control the switchers, use the following commands (connect transmit line from control system to receive line on both switchers):
[I01O01] Select input number 1
[I02O01] Select input number 2
[I03O01] Select input number 3
[I04O01] Select input number 4
[I05O01] Select input number 5
[I06O01] Select input number 6
[I01O02] Select input number 7
[I02O02] Select input number 8
[I03O02] Select input number 9
[I04O02] Select input number 10
[I05O02] Select input number 11
