ESTING COMMANDS PLACED ON THE VIRTUAL KEYPAD
Commands placed under buttons in the Virtual Keypad window may be tested prior to downloading to the
MRC88 Controller. To test commands, the Dragon PC must be connected to the front panel COM PORT or
USB Port and emitters must be placed in the proper Source and Zone IR Emitter output ports. For Fast Testing,
an emitter placed in the COMMON IR port will be sufficient.
1. Select the appropriate button on the Virtual Keypad with the IR codes placed under it to test. (i.e. The
PLAY button:). The button should be outlined in blue.
2. Select the TEST button located in the bottom right-hand side of the Virtual Keypad window. Commands
listed under the Macro Command List for that selected Command should now be executed in order of
appearance out of the proper Ports on the MRC88 Controller.
PROGRAMMING POWER MANAGEMENT AND SENSE TRIGGER CODES
The MRC88 has the ability to control and manage all of the source components connected to the system
keeping all components powered ON when any zone is active and to turn all components OFF 10 seconds after
the last Zone is powered down (Power Management feature). The MRC88 also polls these components
continuously, checking the power state every 10 seconds and comparing it to the system just in case a
component gets out of sequence such as during power surges or other miss-happenings.
The MRC88 Controller features two sensing methods. One is Video Sensing. All eight source video inputs are
set to detect a video input signal (NTSC and PAL sync). When video is detected, the MRC88 controller knows
when to send or not send power commands to keep components in sync with system activity. The other method
is Current Sensing. Current Sensing functions the same way, but detects the difference in current drawn by
the component when it’s either ON or OFF(Standby Mode). Current Sensing requires the use of the CSM1
Current Sense Module (not included).
In ADVANCED mode, the system also has the ability to trigger Command Macros with a power state (i.e.
change a lighting scene when a device is turned on). This is called Sense Trigger.
Programming for these two features is explained below.
PROGRAMMING POWER MANAGEMENT
Power Management operates by checking all Zones Power ON/OFF status of the MRC88 System and
comparing it to the Power ON/OFF state of the Source Components. If the two states disagree the Controller
will send out the appropriate Power Command to the source Component until they are the same (If any Zone of
the MRC88 System is ON it will make sure all Components listed under Power Management are also ON).
[One or More Zones ON] AND [Source Component OFF] = Issue IR command listed under POWER ON in
the Power Management Window to Source Emitter Port
[One or More zones ON] AND [Source Component ON] = Do nothing.
[All Zones Off] AND [Source Component ON] = Issue IR command listed under POWER OFF in the Power
Management window to Source Emitter Port
[All Zones Off] AND [Source Component Off] = Do nothing.
NOTE: IR commands issued for power management will be output from the corresponding source IR and
common IR outputs.
