IR Learning indicators
— Each button on the MLC front panel has four
memory blocks, which can be programmed with up to four IR (or RS-232)
commands. The IR Learning indicator LEDs provide visual feedback,
indicating the following:
• Which of the four memory blocks contains a command
• Which of the four memory blocks is ready to be programmed or
configured
• The IR Learning status of the controller
2
Enable Macro LED
— The LED located immediately above the four green IR
LEDs is labeled E, for Enable Macro. This LED lights amber when you place a
button in macro mode. (See
Setting up macros
, in chapter 3.)
3
IR Learner/transmitter
— These sensors allow for IR control of the MLC and
for IR learning. The two LEDs (one for transmitting, one for receiving) send
and receive IR signals, enabling the MLC to learn commands and clone
configurations from another MLC.
The IR remote control must be pointed directly at these LEDs for best results.
The MLC can “learn” IR commands in order to control the projector. IR
learning of projector control codes is necessary only if there are no RS-232
codes available for that projector or if you need to customize the driver. The
IR learning procedure is discussed in chapter 3.
4
Configuration switches
— These DIP switches place the MLC in IR learning
mode or data transfer mode.
•
Switch 1:
Enables IR learning.
•
Switch 2:
Enables data transfer, such as cloning the MLC’s configuration
onto another MLC 52.
•
Switch 3:
Disables IR repeats during playback. For most applications,
this switch is placed in the off position.
Switch 4 is not used.
