SWITCHERS
10
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 11-in 1-out
switcher.
7.6 LOOP CONTROL WITH RS-232 COMMAND
When multiple MX2216RM units are connected to
form a single switcher and RS-232 commands are
used to control these units, please connect the
units according to following diagram.
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
