IR signals from a Mitsubishi Remote are directed to the RMC input of IC7A00. The signals are filtered, pro- cessed and directed over the IR-IN-BUSY line to the SYS-5 µPC on PCB-DTV TUNER. If the SYS-5 cir- cuitry is busy, it holds the IR-IN-BUSY line Low until it is clear to receive data.

If it is a Mitsubishi command the SYS-5 µPC directs it to the DM Module. The signal is processed and routed

back to the TV µPC over the DM-RXD line. If the commands are for a System 5 component they are di- rected to the SYS-5 IR Blaster Outputs.

Other manufacturers IR signals are amplified by the Wide Band Preamp, directed through IC7C50 to the Repeater IR Blaster Outputs. If IR signals are being output at that time the IR-OUT-EN line disables IC7C50 until the current IR output has ended.
