IR OUTPUT PORTS

IR (Infrared) codes are stored in the HT-MSU during configuration programming. The labels of the IR Outputs identify what source number these ports are designed to operate. SRC1 means source

1.The outputs are labeled SRC1 through SRC6, TV/7 and RCV/8. If the TV is to be controlled via IR codes, then the IR Output TV/7 port should be used. However, if the TV will be controlled via RS232, then the TV/7 IR output can be used to control an alternate IR source. These IR outputs are dedicated and routed, meaning IR codes stored for source number 3 (i.e., a DVD player) can only be emitted from the IR output port labeled SRC3. RCV/8 can be used either for the receiver in the home theater or a source number 8.

RS232 OUTPUT PORTS

RS232 is a serial device control protocol that allows sources to be controlled via a transmit-receive cable. (See the Installation section for wiring information.) RS232 codes are stored in the HT-MSU as string codes during configuration programming. The labels of the RS232 Outputs identify what source number they are designed to operate. SRC1 means source 1. The outputs are labeled SRC1 through SRC6, TV/7 and RCV/8. If the TV is to be controlled via RS232 codes, then the RS232 TV/7 port should be used. However, if the TV will be controlled via IR, then the RS232 TV/7 port can

be used to control an alternate RS232 source. These RS232 outputs are dedicated and routed, meaning RS232 codes stored for source number 3 (i.e., a DVD player) can only be emitted from the RS232 output port labeled SRC3. RCV/8 can be used either for the receiver in the home theater or a source number 8.

SOURCE POWER STATUS CONNECTIONS

To properly automate home theater sources, the HT-MSU needs to “know” when the source is powered On or Off. There are three ways that sources are powered on:

1.Toggle Power: A source via its remote control has one button for turning that source On and Off. When trying to automate such a device, you must provide the HT-MSU the “Power Status” as feedback using the Status connection on the HT-MSU’s top edge (detailed below).

2.Separate On and Off Power: A source via its remote control has one button to turn the source On and a different button to turn the source Off. When trying to automate such an IR device, you should provide the HT-MSU the “Power Status” as feedback so the IC2 System will act faster using the Status connection on the HT-MSU. If a source is to be controlled via RS232 and it has separate On and Off codes, you do not need to provide the HT-MSU feedback.

3.Latching Power: Latching power is an industry term that means the source has no power command/s on its remote control. A latching power source may have a “hard” power button on the front panel. To determine if a source is latching power, push its “hard” power button in, take its power cord and plug it into a live AC power outlet. If it turns on when plugged into the outlet and turns off when unplugged from the outlet, it is a latching power source. Latching power sources do not need a Power Status
