displaying the appropriate information on its LCD screen, there is no need to check these
LEDs on the HAL. If a RAD indicator is solid red or the DR is reporting a problem, however,
view the corresponding indicators on the HAL to determine if the problem is originating there.
Following are descriptions of the indicators on the HAL:
RADs:
o
The RAD indicators on the rear panel correspond with the indicators on the individual
RADs, providing information on the health of the wiring. If a RAD is functioning prop-
erly and the HAL is communicating properly with the RAD, all four indicators on the
rear panel of the HAL should be green for each connected RAD.
o
The RAD indicators on the front panel provide information about the actual connection
and any activity between each RAD and the HAL. For each port to which a RAD is
connected, the Enabled indicators for each active RAD channel should be yellow. (If
the Enabled LEDs are flashing yellow, they indicate the RAD model specified in the
HAL configuration does not match the physical RAD model detected on the port.) If
audio is flowing through the system, you may see activity on the Signal and/or Over-
load indicators.
DRs:
o
The DR indicators on the front panel provide information about the actual connection
between each DR and the HAL. If everything is A-OK, the DR LED should be solid yel-
low. If the LED is flashing yellow, this indicates a mismatch between the physical DR
and the configured DR for this port.
o
The DR indicators on the rear panel provide information about the health of the wiring,
indicating if the data communications and power are functioning properly. If solid
green, all is well. If one or both LEDs turn red, this typically indicates a problem with
that specific twisted pair.
5. When you are confident that a device is working properly, you can attach it to the switchbox:
l
If installing a RAD, insert its label before attaching it to the switchbox (if it was not
already labeled off-site). The RADs are shipped with factory labels inserted. You can
use these, but in most cases you will probably want to customize the label. If your
audio designer did not provide you with customized labels, you will need to generate
them. See "Generating RAD Labels" on page 34 for details. Insert the paper label in the
slot behind the Lexan window and trim the excess paper. If you do not need to use the
label slot (for example, you may be labeling the RAD some other way), you can flip
over the factory-provided label and insert it.
l
If a RAD contains an XLR tab and you do not need it, you should remove it before
attaching the RAD to the wall. You can do so by inserting something with a small tip
in the back of the RAD where the XLR tab is connected. Push down on the metal con-
nection and pull the XLR tab away from the RAD. The connectors in the RADs are
manufactured by Neutrik. We have found that the pins provided by Neutrik for removal
of the XLR tab work much better for this task than paper clips, straight pins, or any-
thing else you might find lying around the office. If you do not have a Neutrik pin avail-
able, contact Rane Corporation and we will gladly send one to you.
l
Use the captivated screws on the RAD or DR to attach it to the switchbox. Note that
the screws are in slots so that you can adjust the device if need be (for example, to level
it inside a switchbox that isn’t level). Also, take note of the four metal circles at the top
and bottom of each device—the ones that look like Mickey Mouse ears! You can bend
or snap these off and use them for various purposes. For example, if the switchbox is not
