Making Cascade Connections
The Emerge EMS series of products have been specifically designed to be flexible in order to
support both your immediate and future needs for media streaming. In addition to the standard
connections made from transmitters to receivers, you can also link extra transmitters to
transmitters and/or receivers to receivers in order to provide more display/speaker outputs. These
non-standard links are called cascade connections.
Important Limitations When Cascading Emerge EMS units
• There should never be more than three cascade connections between the Primary Transmitter
• There should never be more than three cascade connections between the Primary Transmitter
(the one connected to the source PC) and any receiver. The cascade connections can all occur
at the transmitter end or all at the receiver end (EMS1000MP-R only) or at a mixture of both.
• Each cascade connection reduces the overall link length permissible from a transmitter to the
final receiver in a branch. To calculate the recommended overall maximum link length for a
branch, count the number of cascade connections between the Primary Transmitter and the
final receiver in that branch. The effects of cascade connections on overall branch link lengths
are as follows:

EMS1000P models should always be limited to link lengths of 600 feet or less, regardless of
cascade connections, due to a lack of skew compensation adjustments.
The lengths of transmitter cascade connections should never be longer than 6 feet (2m) and can be
The lengths of transmitter cascade connections should never be longer than 6 feet (2m) and can be
considered to have a negligible effect upon overall link lengths.
The maximum resolutions achievable are: 1600 x 1200 x 60 Hz at 200m and 1280 x 1024 x 60Hz
The maximum resolutions achievable are: 1600 x 1200 x 60 Hz at 200m and 1280 x 1024 x 60Hz
at 300m. If you are using lower resolutions then it may be possible to achieve longer transmission
distances than shown in the above table although we do not recommend runs longer than 1000ft
in any installation. If you are running shorter cables then it may be possible to use more cascades
than shown in the above table.
