CHAPTER 2: Introduction to the HAL System Provides status information about mic/line-plus analog inputs connected to the HAL. The numbers correspond to the mic/line-plus input ports on the rear panel. These LEDs provide information on the following: l Overload LED (red) - indicates that the mic/line-plus input is experiencing a signal overload l Signal LED (green) - indicates the presence of an audio signal on the mic/line-plus input 3. Line Output LEDs Provides information about HAL analog outputs. The numbers correspond to the line output ports on the rear panel. These LEDs provide information on the following: l Overload LED (red) - indicates that the line output is experiencing a signal overload l Signal LED (green) - indicates the presence of an audio signal on the line output 4. Digital Remote LEDs Indicates which Digital Remotes are enabled. Each numbered LED corresponds to the Digital Remote port with the same number. If a Digital Remote is connected on a port but its Enabled LED is off, there is likely a problem with the shielded CAT 5e connection or with the Digital Remote itself. If an Enabled LED is flashing, it indicates that the physical Digital Remote model does not match the Digital Remote model specified for this port in the HAL configuration. 5. Remote Audio Ports status indicators Provides information about the RAD audio channels. The numbers at the top of the front panel correspond to the RAD ports on the back of the HAL. For example, the LEDs for number 1 provide information about the RAD connected on port 1. Under each RAD number are LEDs for four audio channels, two input and two output. These four LEDs represent the maximum number of channels a RAD is capable of transporting. However, not all RAD models use all four channels. For example, the RAD1 model provides two microphone inputs, so only the two columns of indicators labeled IN would be active. These LEDs provide information on the following: l Overload LED (red)-indicates that the channel is experiencing a signal overload l Signal LED (green)-indicates the presence of an audio signal on this channel l Enabled LED (yellow)-indicates the availability of the associated audio channel. If a RAD is connected on this port and all Enabled lights are off, this indicates a problem with the shielded CAT 5e connection or with the RAD. If the Enabled LEDs are flashing, this indicates that the physical RAD model does not match the RAD model specified for this port in the HAL configuration. 6. The Ethernet Comm and Link LEDs Provides status information about the HAL Ethernet connection. l Comm LED (yellow) - flashes when HAL has been discovered by at least one PC running RaneLink II1, is solid when Halogen is exclusively connected to HAL, is off when HAL has yet to be discovered. 1A service needed by Halogen to establish a connection with HAL. 17
