Introduction

The following items are included with the M-200i. Make sure that

all of them are present:

• The M-200i itself

• Power cord

* Use only the power cord that was included with the M-200i.

• AC Adaptor

• DOCK cable

• Tablet Stand

• Owner’s manual (the document you’re reading)

985

The explanations in this manual include illustrations that depict

what should typically be shown by the display. Note, however,

that your unit may incorporate a newer, enhanced version of the

system, so what you actually see in the display may not always

match what appears in the manual.

The following input/output units can be connected to the M-

200i’s REAC ports:

• S-1608 stage unit

• S-0816 FOH unit

• S-4000S 40-channel I/O modular rack (Ver. 2.010 and later)

• S-0808 8x8 I/O UNIT

• S-4000M REAC MERGE UNIT

The REAC port on the M-200i does not support REAC

EMBEDDED POWER. When you connect an S-0808, install an

external battery on the S-0808 to power via the DC IN port.

Note, however, that when the connection on the M-200i is

made via an S-4000M or S-4000D, the S-0808 is powered by the

S-4000M or S-4000D, and so no external battery is needed.

In this manual, we may abbreviate these units as the S-1608, S-

0816, or S-4000S, or may refer to them collectively as input/

output units.

Text enclosed in square brackets [ ] indicates a button. For

example, the direction to “press [METER]” means that you are to

press the METER button.

The REAC (Roland Ethernet Audio Communication) interface is

the core of a V-Mixing system. It uses a proprietary protocol

based on Ethernet technology, and allows 40 channels of digital

audio to be sent in each direction via a single Cat5e Ethernet

cable.

REAC can do the following:

• Send 40 channels of digital audio in each direction

• Send audio up to 100 meters on one Cat5e cable

• A switching hub or the S-OPT option can be used to extend

the cable.

• Use a switching hub to easily split the signal

• The transmission delay between REAC devices is extremely

small (approximately 375 microseconds)

When the signal passes through a switching hub, there will be

approximately 200 microseconds of delay for each unit.

Since Cat5e Ethernet cables are used, it’s very easy to connect

REAC devices to each other. Cat5e Ethernet cables are commonly

used for computer network connections, and have RJ45 plugs.

Types of Ethernet cable

There are two types of Ethernet cables. Although both types have

the same exterior appearance, their RJ45 plugs are wired

differently, as follows:

• Crossover cable

The internal wiring of the cable is crossed at each RJ45 plug.

This means that the connections of the RJ45 plugs will differ

at each end of the cable.

• Straight cable

The internal wiring of the cable is the same at each end.

Crossover cables (such as RSS SC-W20F, RSS SC-W100S, or RSS

W100S-R) should be used when connecting to the REAC ports on

this product.

Certain cautions apply if you’re using a conventional switching

hub with this system. For details, refer to “REAC applications” (p.

96).
