Settings for the REAC Ports and Expansion Slots

In the REAC / SLOT window, you make the settings for expansion
interfaces attached to the REAC ports and expansion slots.
* When restarting the unit with the expansion interface installed,
wait for about one second before you turn on the power.

REAC / SLOT Window

To display the REAC / SLOT window, go to the SYSTEM window and
tap <REAC / SLOT>.
The following three tabs are available.

5 REAC A/B tab

Here you make settings for the REAC ports (A, B, SPLIT/BACKUP).
5 SLOT D tab
5 SLOT E tab
Here you make settings for EXPANSION SLOT D or E.
Operation methods differ according to the attached expansion
interface.
REAC A/B Tab
Selects the REAC A/B port REAC mode from
among the following.
5 MASTER
MODE
5 SLAVE

About the REAC SPLIT/BACKUP Port

The SPLIT/BACKUP port is used to split or back up (duplicate) REAC
A or B. In the REAC / SLOT window REAC A/B tab, you use <TARGET>
to specify split/backup for either the REAC A or B port.
Whether split or backup is performed is set automatically according
to the connected equipment.
If the device connected to the SPLIT/BACKUP port supports a
REAC backup (redundant) connection, then if a problem occurs
in the main REAC connection (the REAC A or B port), the system
automatically switches to the backup REAC connection (the SPLIT/
BACKUP port).
When using an Ethernet switching hub to extend the REAC backup
connection, use the same model of switching hub for both the
main REAC connection and the backup REAC connection.
When a split REAC device is connected to the SPLIT/BACKUP port,
audio is distributed to the split REAC device.
The REAC SPLIT/BACKUP port is compatible with REAC EMBEDDED
POWER, and can supply power to devices compatible with REAC
EMBEDDED POWER.
When a REAC device is connected, the system automatically detects
whether the device is compatible with REAC EMBEDDED POWER
and supplies power if compatible. Power is not supplied if the
device is not compatible with REAC EMBEDDED POWER.

Requirements for switching hubs

Switching hubs used to connect REAC devices must meet the
following conditions:
5 We recommend a switching hub that supports 1000BASE-T
(IEEE 802.3ab, Gigabit Ethernet)
5 100BASE-TX interface must be supported (IEEE 802.3u, Fast
Ethernet)
5 Full duplex communication (simultaneous bidirectional
communication) must be supported

Caution when using a switching hub

5 The network propagation time between REAC devices is
approximately 375 microseconds, but if the signal passes
through a switching hub, there will be approximately 200
microseconds of delay for each unit.
5 Up to four switching hubs can be connected in series.
5 Connect REAC devices to a switching hub that supports
100BASE-TX.
5 Carefully read the owner's manual of the switching hub you use.
