TB14 and TB14H 10Mb Media Converters Installation and User Guide (09/04)
All of the Magnum “TB14s” 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 and also an
( ∝ - 50Ω ) internal termination switch to control the BNC port by eliminating the TEE –
Connector. The BNC connector complies with IEEE 802.3 10BASE2 specifications.
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.

2.4 Applications
The primary function of a 10Mb Ethernet Media Converter is to permit two
different 10Mb media types to coexist inexpensively within the same network by
allowing data to be transmitted and received between different media types.
Magnum “TB14s” Media Converters are typically used where new 10BASE-T
networking equipment is being installed and connected to existing BNC Ethernet cabling.
Magnum “TB14” Media Converters have an external AC power supply and internal DC
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 and BNC. The
wide variety of options of AC and DC power supply qualify the TB14 s for use in office
locations as well as industrial and even outdoor applications.

In this application, in a Industrial environment where extended temp. supported units is a
requirement, the existing BNC network needs to connect with RJ-45 ports in a hub /
switch to expand the existing application. The rugged Magnum TB14s with various
extended temperature features easily qualifies to be deployed in this requirement and
smoothly serve the needs by changing BNC media to RJ-45.

3.5 Calculating Overall Segment Distance
Important Note
: Special consideration must be given to maximum cable
segment lengths of a Magnum TB14 and TB14H Media Converter. It is recommended
that IEEE 802.3 specifications for overall maximum segment distances be adhered to in
order to maintain optimum network performance. (See also Technical Specs, Maximum
Standard Ethernet Segment Distances, Section 1.1 of this manual.)
When installing the Magnum TB14s 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. Cable segment length on each side of the Media Converter
is 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%.

TB14 and TB14H 10Mb Media Converters Installation and User Guide (09/04)
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%
A Distance Calculation Example:
Connectivity between ThinNet and TP Ethernet Media.
In this example, 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 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.

..
30
TB14 and TB14H 10Mb Media Converters Installation and User Guide (09/04)
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 Magnum BNC Media Converters that can be
used in series is three. The cumulative noise from more units together causes packet
alignment errors and excessive dropped packets.

TB14 and TB14H 10Mb Media Converters Installation and User Guide (09/04)
3.6 Connecting Ethernet Media
It is recommended that both of the media (TP and BNC) be connected with
power off so that both ports are connected when power is applied to the logic in the
electronics. If power is on, connect the Twisted Pair media before the BNC media. If
BNC is connected before TP with power on, it can create a Jabber condition, in which
case the JAB LED will come on and no packets will be processed.
See Sections 4.4 for details of the LEDs on the media converter models.
3.6.1 Connecting Twisted Pair (RJ-45 ports)
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.
www GarrettCom com
..
32
TB14 and TB14H 10Mb Media Converters Installation and User Guide (09/04)
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.
Use the LINK LED 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 4.6 for uplink switch information.) If this does not help, ensure that the cable is connected
properly at both ends and is not defective.
3.6.2 Connecting ThinNet (10BASE2)
Note: connect TP media before connecting BNC media if power is on in the
Media Converter unit. See Section 3.6 Connecting Media above.
www GarrettCom com
..
33
TB14 and TB14H 10Mb Media Converters Installation and User Guide (09/04)
Connect the ThinNet coax cable to the BNC connector on the TB14s 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.
The TB14s media converter is also equipped with “Terminator
Switch” (∝-50Ω), which can be used to eliminate the standard “T” connector by moving
