Introduction
Ethernet connectors
Ethernet cables use RJ45 plugs. REAC equipment provides an RJ45
connector for each REAC port.

For critically important communication, it is vital to protect the RJ45
plug and connector. For such situations, REAC RJ45 connectors use a
sturdy Neutrik EtherCon plug. Using the EtherCon RJ45 plug allows
a latched-type connector similar to an XLR plug.
Neutrik Corporation provides EtherCon RJ45 plugs as well as The
Neutrik Corporation manufactures EtherCon RJ45 plugs, as well as
EtherCon plugs that can be added to the RJ45 plug of commercially
available Ethernet cable.
The RJ45 connectors of REAC ports can accept either RJ45 plugs
or EtherCon plugs.
Cautions for handling Cat5e cables
• Do not apply excessive force to Cat5e cables.
• Do not bundle (bend) a Cat5e cable to a radius less than 25 mm,
or fold it in two.
• Do not tightly bundle a Cat5e cable.
• Do not place multiple Cat5e cables in parallel for an extended
distance.
• Do not place Cat5e cables near a source of electrical noise
(power supply cord, motor, fluorescent lights, etc.).
Here is a typical example of connections using the S-1608.
When connecting REAC devices to each other, the REAC mode of
one device must be set to Master, and the REAC mode of the others
must be set to Slave.
In this system, the M-400 is normally set to be the master (FOH
setting), while the input/output units are set to be slaves.
For a more detailed description of connections, refer to “REAC
applications” (p. 181).
Cat5e Ethernet cables up to 100 meters long are supported. If
you need a longer connection, we recommend that you use the
optional S-OPT.

Cautions when making REAC
connections
• REAC connections are designed so that noise will not be
produced even if you hot-swap (plug or unplug a live
connection). However in rare cases, noise may occur at the
audio output of the system. To prevent hot-swapping from
causing damage to your speakers or other equipment connected
to the audio outputs, please observe the following points.
• Make REAC connections while holding down the [MUTE ALL
OUTPUTS] of the input/output unit
• Before you make REAC connections, mute the outputs using [F6
(MUTE ALL OUT)] in the MUTE GROUP screen (p. 145).
In some cases, the muted state will continue even after you
release your finger from [MUTE ALL OUTPUTS] of the input/
output unit. In this case, press [MUTE ALL OUTPUTS] once
again to mute, and then release your finger to unmute the unit.
