Professional Multimedia Switch Crestron C2N-MMS
The sync input impedance can be set to either 1k, 500, or 75 ohms. The setting from
the factory is 1k ohms and should work with most RGB sources. If the signal quality
is poor, lowering the input impedance to match the impedance of coax cable may
alleviate sync signal problems that are associated with RGB cables greater than the
typical VESA standard (typically six feet).
For laptops that require the presence of a monitor to enable its video output, the
C2N-MMS has a selectable feature (DDC) that simulates the presence of a generic
high-resolution monitor so RGB sources (such as a laptop computer) will transmit a
signal even when a RGB device is not connected to the C2N-MMS output. Changing
a DIP switch setting can enable or disable this feature. The C2N-MMS is shipped
from the factory with the DDC feature disabled.
NOTE: The sync input impedance and DDC feature should be set prior to placing
the C2N-MMS in an equipment rack.
Finding the DIP Switches
The DIP switches that configure the RGB input ports are located inside the
C2N-MMS. The only tools required are a #2 Phillips screwdriver and a grounding
strap (or grounded workstation).
CAUTION: The C2N-MMS contains ESD-sensitive devices. Perform the following
procedure while wearing a grounding strap that is properly grounded or on a
grounded workstation to avoid damaging the C2N-MMS.
1. Make all connections to the C2N-MMS as described in “Hardware
Hookup” on page 11.
2. Open the C2N-MMS by removing the 16 screws (located on the sides and
top of the C2N-MMS) securing the top cover. Use a #2 Phillips screwdriver
to remove the screws.
3. Remove the lid to expose the DIP switches as shown in the following
diagram.
