Remove the Magnum Media Converter from the shipping container. Be sure to
keep the shipping container should you need to ship the unit at a later date.
In the event there are items missing or damaged contact your supplier. If you need
to return the unit use the original shipping container. Refer to Section 5,
Troubleshooting, for specific return procedures.
2.2 Product Description
Magnum TF14 and TB14 10Mb Media Converters offer a compact, cost-effective
way to adapt to non-RJ-45 Ethernet cabling as network requirements change and grow.
The design provides units that are very small, power-efficient, but also full-function.
The “14” series offer a graceful way to convert and transmit data among twisted
pair, fiber and thin coaxial network cabling environments. A variety of twisted-pair-to-
fiber models provide for multi-mode or single-mode, transparent full- and half-duplex
mode, and normal or Link Pass-through operation. Magnum TF14 and TB14 Media
Converters cost significantly less than full repeaters and can be used whenever media
distance limitations will not be exceeded in the segment. All units are compatible with
Ethernet V 1.0 / 2.0 specifications and comply with IEEE 802.3 standards.

Magnum TF14 and TB14 10Mb Media Converters are designed for quick and
easy installation even in very tight spaces. Media cables are easily attached to the
corresponding Media Converter. Because of their compact size, Magnum Media
Converters can be Velcro®-mounted on an office wall or the side of a desk or cabinet. A
rack-mount tray that neatly holds the units and associated power supplies is available.
The standard “1-per-unit” external power supply plugs into a nearby AC wall
socket or power strip. Each converter features a full set of LEDs that convey essential
diagnostic and status information. See Section 4.1, for LED function specifications.
Magnum Media Converters are designed to provide low-temperature operation
over an extended period to make them some of the most reliable in the industry. Their
high-strength fabricated steel packaging shields against Radio Frequency Interference
(RFI) and Electromagnetic Interference (EMI).
Magnum TF14 and TB14 10Mb Media Converters are specifically designed to
convert data signaling to allow transmission between two different Ethernet cabling
types, allowing migration to a new media type while preserving segments of the pre-
existing wiring structure. In addition, the TF14 allows fiber segments to be used with
new RJ-45 Ethernet hubs and switches that have insufficient (or none at all) fiber ports.

All of the Magnum “14” Media Converters comply with the IEEE 802.3
10BASE-T specification for 10 Mb/sec traffic via shielded (STP) or unshielded twisted
pair (UTP) segments. They feature an up-link or cross-over switch to eliminate the need
for a special cross-over cable when connecting to a hub or concentrator.
Note: experience shows that the maximum number of 10Mb Media Converters
that can be used in series is three. The cumulative signal noise from 4 or more units
together in series may cause packet alignment errors.
Fiber models: The Magnum TF14 (multi-mode ST), TF14s (single-mode ST), and
TF14-LP (Link Pass-through, ST) are equipped with one fiber-ST and one twisted pair
RJ-45 connector for use in IEEE FOIRL or 10BASE-FL compliant networks. The up-link

All fiber models operate in transparent full- or half-duplex mode, supporting
matched sets of either mode type, i.e., attached devices are either both full-duplex or both
half-duplex.

The
Magnum TB14 is
equipped with one
BNC and one RJ-45
port. The BNC port
has an internal
termination switch, allowing BNC attachment without a “T” connector. The BNC
connector complies with IEEE 802.3 10BASE2 specifications.

2.3 Features and Benefits
!
!!
!Reduces Network Costs
Magnum Media Converters offer the ideal solution to quickly and
inexpensively connect Twisted Pair with Fiber or ThinNet media within
an expanding Ethernet network where full repeaters are not required.
!
!!
!No added Repeater Hop Count
Media Converters do not add signal timing delays associated with full
repeaters, and can be installed without increasing the repeater hop count
of an existing network.
!
!!
!Fiber / twisted-pair models for all fiber modes
A variety of twisted-pair-to-fiber models provide for multi-mode or single-
mode fiber, transparent full- or half-duplex mode, ST connectors, and
normal or Link Pass-through operation.
