GTP-870HD Owner’s Manual

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 GTP-870HD 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 GTP-870HD is powered on or a particular in-

put is selected.

• RS232 Port - This allows you to control the GTP-

870HD with a home automation system or to up-

grade the unit’s ﬁrmware through the RS232 port

on your PC.

Remote IR Sensor Connections

1 Obtain 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.

3 Connect the remote IR sensor’s mono mini-plug

to the Main IR input on the GTP-870HD.

4 Conﬁrm the remote IR sensor is working.

• Conceal the GTP-870HD front panel and at-

tempt to control the unit by pointing the re-

mote at the remote IR sensor.

Screen/Power Trigger Connections

1 Using 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.

2 Make sure the Main Trigger is enabled in the

menu system; see page 33.

• The default setting is on for all inputs.

3 Conﬁrm the trigger is working.

• Power on the GTP-870HD or select the input

for which the main trigger is enabled.

• The connected device should power on.

PC Connections

1 Contact Adcom for information on the avail-

ability of ﬁrmware updates and instructions for

implementing them.

2 When instructed, use an RS232 cable to connect

the RS232 port on the GTP-870HD to the RS232

port on your PC.

Media Center & Home Automation Control Systems

1 The RS232 port can also be used to control the

GTP-870HD from a media control center, home

automation system, or PC.

• See Discrete Remote Control Commands on

pages 53-54 for more information.

Notes:

• To conﬁgure the Main 12V DC

trigger, see page 33.

• For a list of Discrete Remote

Control Commands, see pages

53-54.

• 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.
