Control Connections

Sensors, triggers, and PCs, oh my. If you’ve gotten this far, you’re really fine-tuning your home theater. This section is all about control:

Remote IR sensors - These allow you to control your GFR-700 even if it is behind closed doors or otherwise concealed from view.

Triggers - These allow you to automatically power on connected devices, such as motorized movie screens and connected amplifiers, when the GFR-700 is powered on or a particular input is selected.

RS232 Port - This allows you to control the GFR- 700 with a home automation system or to up- grade the receiver’s firmware through the RS232 port on your PC.

Remote IR Sensor Connections

1Obtain a remote IR sensor.

Choose a remote IR sensor from an electron- ics distributor that suits your particular in- stallation needs.

Install the remote IR sensor according to the manufacturer’s instructions.

3Connect the remote IR sensor’s mono mini-plug to the Main IR input on the GFR-700.

4Confirm the remote IR sensor is working.

Conceal the GFR-700 front panel and at- tempt to control the receiver by pointing the remote at the remote IR sensor.

Screen/Power Trigger Connections

1Using a cable with dual mono mini-plugs, con- nect the Main 12V DC trigger jack to the 12V DC trigger on your compatible device.

Common compatible devices include ampli- fiers, motorized screens, and high-end au- dio/video components.

2Make sure the Main Trigger is enabled in the menu system; see page 33.

• The default setting is on for all inputs.

3Confirm the trigger is working.

Power on the GFR-700 or select the input for which the main trigger is enabled.

The connected device should power on.

PC Connections

1Contact Adcom for information on the avail-

ability of firmware updates and instructions for implementing them.

2When instructed, use an RS232 cable to connect the RS232 port on the GFR-700 to the RS232 port on your PC.

Media Center & Home Automation Control Systems

1The RS232 port can also be used to control the GFR-700 from a media control center, home au- tomation system, or PC.

See Discrete Remote Control Commands on pages 49-50 for more information.

Notes:

To configure the Main 12V DC trigger, see page 33.

For a list of Discrete Remote Control Commands, see pages 49-50.

The 12V trigger is simply a “trigger” and not a relay driv- er. Some motorized screens will require an outboard de- vice to be used in association with the 12V trigger. See the screen manufacturer’s instruc- tions or ask your dealer or distributor.
