REAC applications
This chapter explains more advanced ways to use REAC.
For basic information about REAC, refer to “Basic knowledge
about REAC” (p. 13).
By connecting a REAC splitter between the REAC master and
slave, you can split the output from the REAC master device and
distribute it to multiple REAC split devices.
fig.REACsplit.eps
To assign a REAC device to operate in split mode, you must set its
REAC mode to Split. The REAC split device will function solely to
receive signals from the REAC master device.
Caution when using a REAC splitter
For a REAC splitter, you can use the S-4000-SP, S-4000D, or an
Ethernet switching hub. Switching hubs that meet the following
conditions can be used with the M-300:
•
1000BASE-T compatible device (IEEE 802.3ab, Gigabit
Ethernet) that supports 100 BASE-TX (IEEE 802.3u, Fast
Ethernet)
•
Full duplex communication (simultaneous bidirectional
communication)
The network transmission time between REAC devices is
approximately 375 microseconds, but if the signal passes
through a REAC splitter (S-4000-SP, S-4000D, or an Ethernet
switching hub), approximately 200 microseconds of delay will
occur for each device. A maximum of four REAC splitters can be
connected in series.

REAC A port
The REAC A port belongs to the REAC A system. The REAC A port
operate as the REAC master or the REAC slave.
REAC A port output
The forty channels from the output patchbay are output to the
REAC A port.
fig.ReacAOuts.eps
When the M-300’s REAC is set to MONITOR/BROADCAST (p. 140),
the REAC A port operates as the REAC split. In this case, the M-300
cannot output signals to the REAC A.
REAC B port
The REAC B port belongs to the REAC B system, which is separate
from the REAC A port. The REAC B port always operates as the
REAC master.
REAC B port output
The forty channels from the output patchbay are output to the
REAC B port.
