Magnum 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.
All of the Magnum 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. The Media Converters 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 noise from 4 or more units together
causes packet alig nment errors.

Magnum Media Converters have an external power supply, enabling them to be
used to convert signals among media that does not have a power source as part of the
cabling system, such as twisted pair, BNC and Fiber. (AUI ports can supply power).
2.5 Full / hal f-duplex applications.
Of the various 10Mb media types, only the twisted-pair to fiber combination is
capable of full-duplex (i.e., simultaneously transmitting and receiving on the same cable
segment) operation. Full-duplex is rarely required at 10Mb, but might occasionally be
desired to connect a 10Mb RJ-45 switch port over a fiber link to a full-duplex RJ-45 NIC
in a remote server, or to connect to another full-duplex 10Mb RJ-45 switch port.
The various TF15 units tagged FULL/HALF DUPLEX operate transparently to
the simultaneous TX / RX condition, and do not indicate Collisions or Jabber even if
they are present. They are suitable for all normal half- and full-duplex applications.

recommended that IEEE 802.3 specifications for overall maximum segment
distances be adhered to in order to maintain optimum network performance.
(See Technical Specs, Maximum Standard Ethernet Segment Distan ces,
Section 1.1 of this manual.)
3.2 Calculating Overall Segment Distance
When installing the Magnum Media Converter, it is important to consider the
combined overall segment length of both of the attached media types. The overall
segment length is calculated by adding together the segment lengths on both sides of the
Magnum Media Converters. Segment length on each side of the Media Converter is
Special consideration must be given to maximum
GARRETT
24
Magnum 10Mb Media Converters Installation a nd User Guide (07/98)
measured as a percentage of the maximum allowable standard media distance for the
given media type. The percentages, when added together, must not exceed 100%.
Media Distanc e * Formula for Magnum Me dia Converters:
X% + Y% < 100%
Where X = The segment distance on one side of the Magnum
Media Converter divided by the Standard Maximum
Media Distance for that media type, x 100%
Where Y = The segment length on the other side of the Magnum
Media Converter divided by the Standard Maximum
Media Distance for that media cabling type, x 100%
Notes:
1) Media distance calculation is the same for both half and full duplex media converters.
2) Single-mode fiber distances more than approximately 4Km will exceed the collision

In the figure shown above, the length of Segment X is 72m (216 ft). This is
39% of the maximum allowable distance for 10BASE2 media (185 m) [72/185 x 100% =
39%]. The length of Segment Y is 55m (165 ft). This is 55% of the maximum allowable
GARRETT
27
Magnum 10Mb Media Converters Installation a nd User Guide (07/98)
distance for UTP 10BASE-T media (100 m) [55/100 x 100% = 55%]. The total of the
two percentages (39% + 55%) is 94%, which is allowable.
Note 1
:
Where more than one media converter is used in one
segment run, the percentages for all of the cabling lengths in the run
must be added together and must not exceed 100%.
Note 2
:
If the total segment distance calculation result is greater than
100%, consider using a Magnum Repeater so that each cable type can
be 100% of its maximum allowed length.
Note 3
: The maximum number of 10Mb Media Converters that can
be used in series is three. The cumulative noise from four or more
units together causes packet alignment errors.

3.3 Connecting Ethernet Media
Connecting Ethernet media to the Magnum Media Converter is very simple and
straightforward. Using a properly terminated media segment, simply attach the cable end
to the appropriate connector.
See Sections 4.2 and 4.3 for a description of the LEDs of the media converter
models.
3.3.1 Connecting Twi sted Pair (RJ-45, standar d and Link Pass-through models)
The following procedure describes how to connect a 10BASE-T twisted pair
segment to the RJ-45 port on the Magnum Media Converters. The procedure is the same
for both unshielded and shielded twisted pair segments.
GARRETT
29
Magnum 10Mb Media Converters Installation a nd User Guide (07/98)
1. Using standard 10BASE-T media, insert either end of the cable with an RJ-45
plug into the RJ-45 connector of the Magnum Media Converter.
2. Connect the other end of the cable to the corresponding device.
3. Use the LINK LED (non-Link pass-through models) to ensure proper
connectivity by noting that the LED will be illuminated when the units are
powered and proper connections established. If the LINK LED is not illuminated,
change the setting of the up-link switch (See Section 4.4 for up-link switch
information.) If this does not help, ensure that the cable is connected properly at
both ends and is not defective.
4. For the TF15LP model with the Link-Pass-through feature, The two LINK LEDs
operate together, and either both LEDs are lit or neither is lit. Both of the
attached cables must be operable for LINK to be indicated. Absence of LINK
does not point to the problem cable segment, and the fault may be in either.

3.3.2 Connecting ThinNet 10BASE2
Connect the ThinNet coax cable to the BNC connector on the TB15 Media
Converter in the same manner as is done for any standard BNC connection. Be sure that
the BNC segment is properly terminated using a standard “T” connector and terminator.
3.3.3 Connecting Fiber Optic multi-mode, si ngle mode
The following procedure applies to 10BASE-FL multi-mode and single mode
applications using the TF15, TF15s, TF15SC, TF15LP and TF15-hdx Media Converters.
All have ST-type fiber connectors, except the TF15SC which has SC-type connectors.
The TF15s single-mode differs from the other fiber media converters in terms of
the maximum distance allowed. The others are used for a multi-mode fiber segment
lengths of up to 2km. The TF15s is used for single-mode fiber segments of up to 10km
in length. The following table is provided for general information:

3. Connect the Transmit (TX) port (light colored post) on the Magnum Media
Converter to the Receive (RX) port of the remote device. Begin with the colorcoded strand of the cable for this first TX-to-RX connection.
4. Connect the Receive (RX) port (dark-colored post) on the product to the Transmit
(TX) port of the remote device. Use the non-color coded fiber strand for this.
5. The LINK LED corresponding to the fiber port on the front of the product will
illuminate (for standard non-Link-Pass-through models) when a proper
connection has been established at both ends (and when power is ON in the units
at each end). If LINK is not lit after cable connection, the normal cause is
improper cable polarity. Swap the fiber cables on the product connector to
remedy this situation.
6. For the Link Pass-through model, connection is the same except that the LINK
indication will not be present unless LINK is made for the cables on both sides.

5.1 Before Calling for Assistance
1. If difficulty is encountered when installing or operating the Magnum Media
Converter, refer back to Section 3.0, Installation and Section 4.0, Operation. Check to
make sure that the various other components of the network are operable.
2. Check the cables and connectors to ensure that they have been properly
connected, and the cables/wires have not been crimped or in some way impaired during
installation. (About 90% of network downtime can be attributed to wiring and connector
problems.)
3. Make sure that the external DC power supply is properly attached to the
unit, that it is of the proper type, and that it is plugged into a functioning electrical outlet.
Use the PWR LEDs to verify the unit is receiving proper power.
