Rear Panel
D [PRIMARY]/[SECONDARY] Connectors
The Rio can be connected to other Dante-compatible
devices (such as a CL-series product) via these
etherCON (RJ45) connectors using standard Ethernet
cables (CAT5e or better recommended).
If DIP switch 4 on the front panel is set upward (to
DAISY CHAIN), audio signals coming into one of
these connectors will be output from the other. Refer
to “Daisy Chain Network” in the “About Connections”
section (see page 13) for more information on daisy
chain connections.
If DIP switch 4 on the front panel is set downward (to
REDUNDANT), the [PRIMARY] connector will be
used for primary connection, and the [SECONDARY]
connector will be used for secondary (backup)
connection. If the unit is unable to transmit signals
through the [PRIMARY] connector for some reason
(e.g., due to damage or accidental removal of the
cable, or a failed network switch), the [SECONDARY]
connector will automatically take over the
connection. Refer to “About Redundant Networks” in
the “About Connections” section (see page 13) for
more information on redundant networks.
NOTE
• The use of Ethernet cables with Neutrik EtherCon CAT5e
compatible RJ-45 plugs is recommended. Standard RJ45
plugs can also be used.
• Use STP (shielded twisted pair) cable to prevent
electromagnetic interference. Make sure that the metal
parts of the plugs are electrically connected to the STP
cable shield by conductive tape or comparable means.
• Connect only Dante-compatible devices or
GbE-compatible devices (including a computer).
E [LINK/ACT] Indicators
These indicators show the communication status of
the [PRIMARY] and [SECONDARY] connectors.
They flash fast if the Ethernet cables are connected
properly.
F [1G] Indicators
These indicators light when the Dante network is
functioning as Giga-bit Ethernet.
G AC IN Connector
Connect the supplied AC power cord here. First,
connect the power cord to the device, then insert the
power cord plug into the AC outlet.
The supplied power cord features a special latching
mechanism (V-LOCK) to prevent the power cord
from being accidentally disconnected. Connect the
power cord by inserting the power cord fully until it is
locked.
CAUTION:
Be sure to turn the power off
before connecting or
disconnecting the power cord.
Press the latch button on the
plug to disconnect the power
cord.
H [FAN] Switch
Sets the internal cooling fan to operate at either
[HIGH] or [LOW] speed.
This switch is set to [LOW] when the unit is initially
shipped from the factory. As long as the unit is
operated within the specified ambient temperature
range either the [LOW] or [HIGH] setting can be
used. The [HIGH] setting is recommended if the
ambient temperature is high, if the unit is in direct
sunlight even if the ambient temperature is within the
specified operating range, and in any situation in
which fan noise is not a problem.
If two or more Rio units are mounted in the same rack
and the fan speed is set to [LOW], leave a 1U rack
space between every two units. Also either leave the
open spaces uncovered or install appropriate
ventilating panels to minimize the possibility of heat
buildup. If three or more Rio units are mounted
without space in the same rack, set the fan speeds to
[HIGH].
