Owner's Manual

9. RS-232 Connectors
Provide serial control and capabilities for possible future
expansion. The RS-232 connector labeled 1 is available for
performing configuration downloads and Flash memory
software upgrades. The RS-232 connector labeled 2 is
available to support possible future expansion.
10.Trigger Output Connectors
Provide 12V DC output to control connected components.
Two trigger output connectors are available on a removable
terminal block. The connector labeled PWR—the power
trigger output connector—is not configurable. It is activated
when the MC-4 is activated and deactivated when the MC-4
is deactivated. The trigger output connector labeled 1 can be
configured for remote or program operation. See “Trigger
Setup” on page 3-52 for more information.
REMOTE CONTROL OVERVIEW
The MC-4 remote control provides full operation of the MC-4,
performing commands such as menu navigation that are not
available from the front panel. See “Command Matrix” on page
2-9 for more information about the commands remote control
buttons perform when each command bank is active.
OPERATION CONSIDERATIONS
The bulleted items that begin below describe factors that can
improve or impede remote control operation. Observe these
items as well as the remote control battery installation instructions
before operating the remote control.
Please note the following before operating the MC-4 remote
control:
• The remote control must be in line of sight with the front
panel IR receiver. Eliminate obstructions between the remote
control and the IR receiver. The remote control may become
unreliable if strong sunlight or fluorescent light is shining on
the IR receiver.
• For optimal performance, position the remote control at a 30
degree angle no more than 17 feet (5m) from the MC-4. If
the MC-4 is placed inside a glass cabinet, tinted glass will
reduce the remote control range.
• Remote controllers for different components can interfere
with one another. Avoid using remote controls for different
components at the same time.
• The remote control batteries should be replaced as needed.
See “Remote Control Battery Installation” on page 1-5 for
instructions.
MENU NAVIGATION
The remote control Menu arrows must be used to navigate the
extensive menu structure shown in the Appendix. The table on
the next page indicates the navigation functions remote control
Menu arrows perform.
