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 (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:

Notes

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 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 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.
