S-4000 Digital Snake Owner’s Manual

Appendix C: Ethernet Switching Hub Requirements

To be used in a REAC system, an Ethernet switching hub must meet the following requirements:

•

1000BASE-T transmission speed (IEEE802.3ab, Gigabit Ethernet)

•

Support for 100BASE-TX devices (IEEE802.3u, Fast Ethernet)

•

Bi-directional (full-duplex) communication

Connect REAC devices only to switching hub ports that support 100BASE-TX.

The transmission protocol for REAC is based on 100BASE-TX (Fast Ethernet). To transfer 40
channels of digital audio, REAC uses the full bandwidth of this protocol. However, some 100BASE-
TX switching hubs cannot handle this amount of data traffic. Gigabit Ethernet switching hubs
can handle a larger amount of data traffic, so we recommend them for use with REAC devices
(just be sure that the Gigabit switching hub you use supports 100BASE-TX devices).

When using switching hubs in-line for REAC cable length extension, a maximum of four hubs
can be used. (Total cable length with four switching hubs: 500 meters. See Chapter 6 for more
information.)

Consult the switching hub’s documentation for information on its proper use.
