Connecting a Two-Way Ring-Down Device

If a Two-Way Ring-Down Device is to be used, see Figure 4-1 and position the Two-Way Ringdown

Device where the necessary connections may be made. A two conductor communications cable from the

FMU must be routed to the Two-Way Ringdown Device, then an RJ-11 jack must be installed on the end

of the communications cable for connection into the Device. The two conductors in the cable must be

installed in the two middle positions of the RJ-11 jack. Either conductor may be positioned in either of the

two middle positions. Plug the RJ-11 jack into either receptacle on the face of the Device. The two RJ-11

jacks labeled 1 and 2 on the face of the device are not polarity sensitive. Either cable may be plugged into

either jack. Software setup is the same as for a telephone line connection except the phone number

entered in the software is any two digit (minimum) number.

If at least one data-grade analog USA telephone line is available (possibly to a fax machine), the Two-

Way Ringdown Device should be positioned where a cable may be connected between a jack for the

telephone line and the Two-Way Ringdown Device. This will permit Syn-Tech's Product Support to

modem connect with either the FMU or Central Controller, if necessary. The Two-Way Ringdown Device

uses an AC power adapter much the same as the one used by external modems.

FMU Installation

Mounting the FMU Pedestal

NOTE

Very Important! Leave adequate clearance for parts replacement when selecting a mounting location. The

upper cabinet and pedestal doors must open fully, and any attach screws (Pedestal I/O Board, Relay

Assembly) which enter from outside the FMU must remain accessible.

Figure 4-2 illustrates the FMU footprint. The FMU must be mounted on a rigid surface. Asphalt is not a

satisfactory mounting surface. The FMU upper cabinet should not be installed until the pedestal mount is

complete. If desired for a particular application such as an installation in a kiosk, the FMU upper cabinet

may be rotated 180 degrees to permit the pedestal door to open to the inside of the kiosk while the upper

cabinet door faces outside. When using this mount method, leave sufficient work space between the back

of the pedestal and the kiosk wall to permit removal of the screws that retain the relay assemblies and

Pedestal I/O Board.
