    EF-701M - Overview

    The ClearCom Encore EF-701M is a Four Wire RS-422 Partyline Intercom Interface with Call Signal. This interface converts a single channel of standard or TW party line intercom to four-wire audio, while also converting call signals to RS-422 data (and back). The resulting four-wire audio plus RS-422 data can then be sent to a Clear-Com Matrix port, fiber-optic converter (modem) or connected to another EF-701M over twisted-pair cable such as CAT-5E. When used with a Matrix system, the EF-701M allows a party-line channel to be connected to the frame with up to 5000' of cable. With its excellent hybrid null and wide-range level controls the unit may also be used as a best-quality stand-alone two-to-four-wire converter.

    The EF-701M 's low profile and compact size add to its portability. It can easily be mounted on a utility rack shelf and up to three units will fit across in a standard 1-RU rack space. No additional power connection is required, as the EF-701M obtains its DC operating current through the party-line connection on pin 2 of the XLR connector. For systems where only one or two of part- line channels are needed, the EF-701M is ideal. Simply run UTP cable from the Matrix frame to the EF-701M, which is connected to and powered by the party-line system. A rear panel dip- switch on the EF-701M selects connection for the four-wire audio and data as the RJ-45 jack, instead of the DB-15, simplifying set-up.

    In addition to its acting as a visual indicator, call signaling can be used to trigger relays or functions in other intercom equipment. An amber data LED provides the user with continuous status on the data link between two EF-701M's and will indicate whether a proper link has been established. The EF-701M also includes internal jumpers to select different baud rates for the RS-422 data.

    Please Note! This item is just one component of a larger system. Please refer to the diagram for ideas and recommendations for your Clear-Com intercom system.
