NOTE:

NOTE:
For optimum performance, Crestron strongly recommends using DM cable
or CresFiber fiber optic cable, available from Crestron. Other high-quality
CAT5e/STP wiring (such as CresCAT-D) or fiber optic cable (such as InfiniCor300)
may also be used with varying performance. Do not use low-skew CAT5e/STP
cable.
NOTE:
When using fiber, it is recommended that you have at least two spare fibers
for each location. DigitalMedia fiber optic components use SC multimode
connectors.
DMNet Power
Devices connected to each DMNet port can receive power from the DM-MD8X8’s
internal power supply or from an external power supply such as the C2N-SPWS300.
To power a DMNet port using the DM-MD8X8’s internal power supply, install a
jumper on the
EIG
connector from the
E
(External) pin to the
I
(Internal) pin as
shown in the following diagram.
