Remote Configuration and Control Connectors

The following connectors are available for remote configuration and control of the AVT 200HD from a computer or other control system or via IR remote control.

KRS-232/IR connector — Connect a host device, such as a computer, touch panel control system, or RS-232 capable PDA to this 5-pole captive screw connector for entering SIS commands and using the Windows-based control software (see “Wiring for RS-232 Control” later in this section, for information on connecting to this port).

To extend IR control, you can also connect an optional IR Link to this port (see “Wiring for IR Control,” later in this section).

LLAN port — If desired, connect the AVT 200HD to a computer or to an Ethernet LAN via this RJ-45 connector. Through this port, you can control the tuner using SIS commands, the AVT 200HD Configuration & Control Program, or the HTML pages that are pre-loaded on the AVT (see “Ethernet Connection,” on the next page).

The two LEDs on this connector indicate the status of the Ethernet	LAN
connection. The amber activity LED indicates that the RJ-45
connector is transmitting or receiving data. This LED flickers as the Activity		Link
tuner communicates. The green link LED indicates that the AVT is
properly connected to an Ethernet LAN. This LED lights steadily.

MReset button — This recessed button initiates four reset modes on the AVT 200HD. To select a reset level, use a pointed object such as a small Phillips screwdriver to press and hold the button while the AVT is running or while it is powering up (see “Resetting from the Rear Panel” in the “Operation” section).

NReset LED — When you are selecting a reset mode, this LED blinks the appropriate number of times to indicate the level of reset or that the reset is complete.
