Important Notes on Installation and Connections
When using commercially available Ethernet cables to connect REAC devices, fit the included REAC connector covers onto the
REAC ports. Electromagnetic noise may be a problem if these are left unattached.
* Attaching a REAC connector cover is not necessary when you are using optional REAC cables (described below).
* When using commercially available Ethernet cables, be sure to use cables that conform to the Cat 5e (Enhanced Category 5) standard or higher.

Four ferrite cores are included with the R-1000. Attach ferrite cores to all REAC cables being connected to the R-1000. Clamp each
ferrite core onto the cable at a location near the plug at the end of the cable, pressing down on the ferrite core until it clicks
closed.
* When attaching a ferrite core, be careful to avoid pinching your fingers.
* When connecting a REAC device, use a cable that has ferrite cores attached to it.

Observe the following points with respect to the cables used for REAC connections.
• Never use cables with damaged or torn coverings.
• Never step on cables or subject them to undue stress.
• Never wind cables too tightly or bend them over.
• Be sure to use cables that conform to the Cat 5e (Enhanced Category 5) standard or higher.
• No single cable should be longer than 100 meters.
Compared to analog transmission, digital transmission of audio signals by means of REAC (Roland Ethernet Audio Communication) is extremely
resistant to external noise, but depending on the usage environment, in very rare instances, noise can occur. Selection of the wrong cable and
incorrect cable handling are especially likely to cause noise.
To maintain transmission quality, use of the following optional REAC cables is recommended.
• 100-meter cables : SC-W100S (cable only) or W100S-R (with reel)
• 20-meter cables : SC-W20F
