For SW ARxi and SW AR HVxi , pins 12 and 24
are Loop In and Loop Out, respectively. For
SW AR MX, SW AR MX HV, and
SW 6 Composite, pins 12 and 24 are unused.
The tally pins can be used for remote indication of the
switcher's selected input. Tally 1 – 6 (pins 14 – 19) indicate
the switcher's selected input number with a logic low (0V);
the tally pins are normally at logic high (5V). For example,
with switcher input 2 selected, the front panel LED for that
input would be on, tally 2 (pin 15) would be 0V, and the
remaining tally pins would be 5V.
You can use the schematics in figure 25 as a guide to design
and build indicator circuits for the tally pins. An example
of an LED circuit is shown to the left, and two versions of
incandescent lamp driver circuits are shown to the right.
The +5V source on remote connector pin 13 is limited to
100 mA. If a different voltage or a higher current is
required, an external voltage source is required.

5. Power the switcher on.
To operate the IR-101, press the key for the desired input
while aiming the hand-held unit at the IR detector. The
approximate operating range is 30 feet.
To change the selected input to 1 on an
SW AR MX, SW AR MX HV, or
SW 6 Component switcher, remote connector pin 1
must be shorted to ground for less than 2 seconds.
If pin 1 is shorted for 2 seconds or longer, the mode
is displayed by a blinking LED, and the selected
input does not change.
The IR detector receives infrared signals from the hand-
held IR-101 remote control, and it converts them to logic
signals. The logic signals are used by the adapter to
duplicate front panel input selection.
Remote control design information
Contact/manual remote connector pin assignments are
shown in the table on the next page. To select a different
switcher input number through the
remote connector, momentarily connect
the pin for the desired input number to
pin 25 (logic ground).
The duration of a momentary connection is defined
as 250 – 500 milliseconds.
To change the selected input to 1 on an
SW AR MX, SW AR MX HV, or
SW 6 Component switcher, remote connector pin 1
must be shorted to ground for less than 2 seconds.
If pin 1 is shorted for 2 seconds or longer, the mode
is displayed by a blinking LED, and the selected
input does not change.
