Daisy-Chaining Encoders
Encoders can be daisy-chained to one another. This is particularly useful when only a single distribution point and
one display exists in a room. Daisy-chaining transforms multiple encoders into a single multiple-input encoder with a
single multicast IP address.
In the diagram below, three dual-channel OmniStream encoders are connected to a switch. In order to daisy-chain
them, they must be reconnected in a different configuration. Each encoder has been labeled with an arbitrary IP
address, for identification purposes.

IMPORTANT:
The optional OmniStream power supply (AT-PS-48083-C) must be connected to each
encoder that is daisy-chained, in order to supply the required power. Note that since each encoder
must use an external power supply, connection to a PoE switch is not required.
1. Reconnect the encoders to one another, and to the switch, as shown in the illustration below.
2.
Connect the optional OmniStream power supply (AT-PS-48083-C) to each encoder in the chain.
NOTE:
Single-channel encoders do not support daisy-chaining. In addition, the OmniStream R-Type
Encoder (AT-OMNI-512) does not support daisy-chaining and
cannot
be combined with OmniStream
Pro daisy-chain configurations.
3.
Login to AMS. Refer to
Accessing Encoders in AMS (page 16)
4. Click
SESSION
in the menu bar.
5. Create an encoder group for using each encoder in the chain. Refer to
information. Since there are three encoders in this example, each encoder will be listed under the
Session
page,
as shown. Encoders can be added to an encoder group in any order.
