???Use cables having connectors compliant with IEC 60169-8.
???The Canare L-5C2VS or equivalent is recommended.
Optical Cables (optical fiber, SC connectors, multi-mode, core diameter of 50/125 micro meters or 62.5/125 micro meters)
???No single cable should be longer than 2,000 meters.
???Use cables having connectors compliant with ISO/IEC 9314-3.
REAC Cables
???Ensure that the cables used for REAC connections conform to the Cat 5e (Enhanced Category 5) standard.
???No single cable should be longer than 100 meters.
???To maintain transmission quality, use of the following optional REAC cables is recommended.
*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.
About REAC Connector Covers
When using a commercially available Ethernet cable to connect a REAC device, 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???re using an optional REAC cable (described above).
About Ferrite Cores
Two ferrite cores are included with the S-MADI. Attach the ferrite cores to the REAC cable being connected to the S-MADI. 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.

Troubleshooting
The SELECT buttons have no effect.
Is the PANEL LOCK switch set to [LOCK]?
To enable operation, set this to [UNLOCK]. No operation is possible when it is set to [LOCK].
WORD CLOCK input and output contains errors.
The word-clock output of the S-MADI is a signal that the S-MADI re-generates internally based on the signal being input as the clock source. This means that slight difference may occur between the input and output. When splitting signals input from a source device to other devices, use a commercially available split connector (p. 15).
Input and output are not possible.
Is the sampling rate of the connected equipment set to 44.1 kHz or 48 kHz?
The S-MADI supports sampling rates of 44.1 kHz and 48 kHz. Set all connected equipment to the identical sampling rate, matched to the sampling-rate of the S-MADI.
The S-4000H does not support 44.1 kHz or 48 kHz, and so it cannot be connected to the S-MADI.
REAC input is not output from MADI OUT.
When the unit is set to [THRU], signals input to the MADI IN connector are sent from the MADI OUT connector (thru-out). When you want to convert REAC input into MADI output, set the OUTPUT switch to [OUT].
Output contains noise.
Does the frequency tolerance of the sampling clock in the input MADI signal exceed +/- 40 ppm?
If the value is exceeding +/- 40 ppm, S-MADI cannot convert accurately. Connect an external word-clock generator or other such device, and change the CLOCK SOURCE setting to [WORD CLOCK].
Transmission to/from digital snake is not possible.
Is a suitable cable used to make the connection?
Refer to ???About Connection Cables??? (p. 18) and use a suitable connection cable.
Have the REAC mode settings (master, slave, or split) been made correctly on the respective equipment?
Refer to ???Connection Example 1??? through ???Connection Example 6??? and make the correct REAC mode settings.
