Installation guide

These LEDs provide information on the following:

Overload LED (red) – indicates that the mic/line-plus input is experiencing a signal overload

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:

Overload LED (red) – indicates that the line output is experiencing a signal overload

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 mod-

els 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:

Overload LED (red)–indicates that the channel is experiencing a signal overload

Signal LED (green)–indicates the presence of an audio signal on this channel

Enabled LED (yellow)–indicates the availability of the associated audio channel. If a RAD is con-

nected 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.

Comm LED (yellow) – flashes when HAL has been discovered by at least one PC running Rane-

Link II

, is solid when Halogen is exclusively connected to HAL, is off when HALhas yet to be

discovered.

Link LED (green) – indicates if the Ethernet network is connected. If the HAL is connected to an

Ethernet network but the Link LED is off, this indicates a problem with the connection.

7. The Expansion Bus LED

A service needed by Halogen to establish a connection with HAL.
