4.
Remote Audio Ports status indicators
Provides information about the RAD audio channels. The numbers 1 through 4 at the top of
the front panel correspond to the RAD ports 1 through 4 on the back of the HAL. For exam-
ple, 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. How-
ever, not all RAD models use all four channels. For example, the RAD1 model provides two
microphone inputs, so for that model, 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 CAT 5 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.
5. 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 run-
ning
RaneLink II

, is solid when Halogen is exclusively connected to HAL, is off
when HAL has yet to be discovered.
l
Link LED
(green) – indicates if the Ethernet network is connected. If the HAL is con-
nected to an Ethernet network but the Link LED is off, this indicates a problem with the
connection.
6. The
Expansion Network LED
If lit, indicates that an Expansion Network device is properly connected to the HAL. If an
Expansion Network device is properly connected to the port and powered on yet the status
LED remains dark, there is likely a problem with the connection.
7.
Fault, Locate, and Power LEDs
The
Fault LED
flashes red when something in the hardware goes awry. The first step in trou-
bleshooting the problem is to open the Halogen software and check the status of this HAL
device.
The
Locate LED
flashes green when you place this HAL device in Locate Mode (via the Hal-
ogen software). The purpose of this Locate functionality is for verification, when working in
the software, of the physical device you are configuring or viewing.
The
Power LED
lights when the HAL hardware is powered on.
