10. After the firmware transfer is completed, select the Base unit menu item and then select Who am I? It
should now display the correct three-digit firmware version that you just loaded into the MRC44 unit. If this
is true, the new firmware has been successfully installed and is ready for use.
RC68+ IR CODE TRIGGERED SEQUENCER
The MRC44 Controller/Amplifier can generate IR code sequences triggered by single RC68+ commands. This
feature can be useful in eliminating partial sequence execution from hand-held controllers and allowing a wider
range of programmable remotes that can be used with MRC44 that don’t allow sequence programming.
When the MRC44 Controller/Amplifier receives certain RC68+ commands, via the Keypad IR sensor or an
external IR sensor, the system will output a sequence of IR commands. The sequence can be any combination
of Source Commands, RC68+ Commands and Internal Amplifier Commands. The IR codes in the sequence will
be output to Source components via the appropriate emitter output and to the common IR output for control of
other devices and systems. Any Internal Amplifier Commands will be processed by the MRC44
Controller/Amplifier internally.
In the MRC44 System Window, Click on RC68 in the lower right hand corner of the MRC44 System Window
and the image shown in Figure 22 will appear.

Programming RC68+ Triggered Sequences
Example: Turn on a zone, select a source and play a CD player from a single RC68+ command received from a
hand-held programmable remote.
1. Open the MRC44 System Window to the RC68 IR Command Macro Window as shown in Figure 22.
2. Open the palettes for the devices to be controlled in the sequence.
3. Select the RC68+ Sequence Trigger Command. (e.g. Click on button ‘80’. It will be outlined in blue.)
NOTE: The shaded buttons are not available for this application. They are reserved for system set-up
modes. See “Fine Tuning” Page 42.
