5.2 Control via the Infrared Controller
The included RC-44 Infrared Remote Controller has a Power Switch at the top right that
can be used to turn the 1T-MX-3344 on and off. Beneath that switch you’ll find four rows
of selector buttons. The top row controls selections for output number one, the second
row controls input selections for output two and the third and fourth rows control input
selections for outputs number three and four respectively.
Operation is similar to front panel operation but instead of stepping through the
available inputs, you simply press the appropriate input button for the output you wish to
control.
As an example, pressing the second button from the left on the second row of buttons
will cause input number two to appear on output number two. Pressing the third button
from the left on the second row of buttons will cause input three to appear on output two
and so on.
5.3 Control via the RS-232 Option
Using appropriate control codes, it is possible to switch any input to any output under
control of a computer or other hardware control device.
To use this functionality, first prepare a control cable by reference to the table below.
Make certain that you have continuity between the pins as shown.
