1.2 REGULATORY
1.2.1 Maximum Permissible Exposure Limits
DO NOT TRANSMIT with this base station and antenna when persons are within the MAXIMUM
PERMISSIBLE EXPOSURE (MPE) Radius of the antenna. The MPE Radius is the minimum distance
from the antenna axis that ALL persons should maintain in order to avoid RF exposure higher than the
allowable MPE level set by the FCC.
FAILURE TO OBSERVE THESE LIMITS MAY ALLOW ALL PERSONS WITHIN
THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION, WHICH
EXCEEDS THE FCC MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMIT. IT IS
THE RESPONSIBILITY OF THE BASE STATION LICENSEE TO ENSURE THAT
THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS ARE OBSERVED AT ALL
TIMES DURING BASE STATION TRANSMISSION. THE BASE STATION
LICENSEE IS TO ENSURE THAT NO BYSTANDERS ARE WITHIN THE RADIUS
LIMITS.
1.2.2 Determining MPE Radius
THE MAXIMUM PERMISSIBLE EXPOSURE RADIUS is unique for each site and is determined
based on the complete installation environment (i.e. co-location, antenna type, transmit power level, etc.).
Determination of the MPE distance is the responsibility of the VIDAMAX user. Calculation of the MPE
radius is required as part of the installation. The Limit for Uncontrolled Exposure Power Density (Pd )
is 10 W/m2 for fixed mounted device.
The M/A-COM 4.9 GHz VIDAMAX Base Station is a fixed mounted radio. After installation and
commissioning, the safe distance from the 9 dBi omni-directional antenna is greater than 20 cm
(8-inches).
1.2.2.1 MPE Calculation for omni-directional Antenna
This MPE Minimum Distance Calculation is based on using a 9 dBi gain omni-directional antenna
mounted directly to the base station RF port.
Basic M/A-COM 4.9 GHz VIDAMAX Base Station specifications:
P: Maximum Peak Conducted Power = 27 dBm
G: Maximum Omni Antenna Gain = 9 dBi
Frequency Range = 4.94 to 4.99 GHz
R: Minimum Distance between User and Antenna = 0.2 m
Equation from FCC:
Pd = P * G / ( 4 * π * R 2 )
Pd = 0.5 W * 7.94 / (4 * 3.1415926 * 0.2 2) = 7.89 W / m2 < 10 W / m2
8
MM-009804-001
The calculation indicates that the minimum 0.2 meter distance between user and the omni-directional
antenna (directly mounted to the base station RF port) is required when operating the M/A-COM 4.9 GHz
VIDAMAX Base Station.
1.2.2.2 MPE Calculation for Directional Antenna
This MPE Minimum Distance Calculation is based on using a directional antenna with more than 9 dBi
antenna gain.
Basic M/A-COM 4.9 GHz VIDAMAX Base Station specifications:
P: Maximum Peak Conducted Power = 27 dBm;
G: Maximum Omni Antenna Gain – Cable Loss = 27 dBi – 1 dB = 26 dBi; (Use numerical GN value
for the calculation ): GN = 10 ^ (G /10)); For G = 26 dBi, GN = 10 ^ (26 /10) = 398
Frequency Range = 4.94 to 4.99 GHz;
Rmin: Minimum Distance between user and antenna to comply with FCC MPE Level (10 W / m2 );
Equation from FCC:
Pd = P * G / ( 4 * π * Rmin 2 )
Rmin = SQRT( 0.5 W * GN / (4 * 3.1415926 * 10 ) )= SQRT ( 3.9789E-3 * GN )
Rmin = 1.26 m, for G =26 (i.e., GN = 398 )
The calculation provides guidelines for users to estimate the minimum safe distance when a high gain
antenna is connected to the M/A-COM 4.9 GHz VIDAMAX Base Station. The user should always keep a
safe distance from antenna greater than 20 cm or SQRT (3.9789E-3 * GN).

4 DESCRIPTION
The VIDAMAX system delivers public safety grade wireless broadband data services for mission critical
applications, such as video surveillance, broadband hot spots, remote precinct connectivity, and LMR
backhaul.
M/A-COM’s new VIDAMAX broadband network applies the open standard IEEE-based wireless
broadband communications protocol of 802.16 to the 4.9 GHz band, thereby providing true Quality-of-
Service (QoS) while operating on contention-free licensed frequencies.
The VIDAMAX Base Station provides hardened, public safety grade base station infrastructure for M/A-
COM’s 4.9 GHz VIDAMAX broadband network.
4.1 VIDAMAX SYSTEM OVERVIEW
VIDAMAX provides integrated public safety grade wireless broadband video and data services for mission-
critical applications. VIDAMAX combines the security of the licensed 4.9 GHz public safety frequency
band with robust 802.16 technology to create a true public safety broadband network. With this state-of-
the-art network, public safety customers can implement applications such as streaming video, web
applications, economical licensed LMR backhaul, and other bandwidth intensive applications. Since the
network provides guaranteed Quality of Service (QOS), it is especially suited for applications such as
video surveillance, perimeter control, and mobile command. VIDAMAX is integrated with M/A-COM’s
VIDA network allowing seamless sharing of network management and administration.
Figure 4-1: VIDAMAX Wireless Broadband Video and Data Services
4.2 THE VIDA NETWORK SOLUTION
By leveraging advances in standards-based Information Technology, M/A-COM has developed a unique
IP-based network solution to solve the many challenges that critical communications users are confronted
with. These challenges include delivering different types of information reliably, ensuring technology
does not become quickly obsolete, and being able to acquire equipment from multiple vendors.
VIDAMAX addresses these challenges and is part of a total network solution called VIDA (Voice,
Interoperability, Data, and Access). VIDAMAX is fast, secure and standards based and will allow critical
communications customers to obtain access to information that its users need today and into the future.
16
MM-009804-001
Figure 4-2: VIDA Network Solution
Figure 4-2 depicts a picture of the VIDA Network Solution and how many different communications
systems are built on the solid foundation of a wide-area IP network. This provides an open architecture
for the integration of public safety voice and data airlink protocols including OpenSky, EDACS, and
P25IP. This open architecture enables mission critical communications customers to have one integrated
solution to meet numerous voice and data needs.
4.3 THE VIDAMAX NETWORK
VIDAMAX is the broadband extension of VIDA and as a complete broadband distribution system, can
serve as the airlink to the user, as well as a wireless extension of the core IP network upon which the
VIDA network is based (Figure 4-2).
VIDAMAX integrates the sophisticated Quality-of-Service (QoS) and solid security of the 802.16-2004
(WiMAX) protocol with the licensed protection of the 4.9 GHz public safety band to provide public
safety grade wireless broadband data services for mission critical applications.
17
MM-009804-001
Figure 4-3: VIDAMAX Broadband Network
Figure 4-3 illustrates a typical deployment scenario of the VIDAMAX 4.9 GHz broadband network. It
provides secure, public safety grade broadband services to both fixed and mobile clients. Conceptually,
the system can be seen as extending the enterprise WAN to remote locations using the licensed 4.9 GHz
public safety band. Some common applications for this system include:
• Remote surveillance video
• Mobile broadband access to vehicles (“Hot Spots”)
• Connection of remote precincts to the enterprise and/or VIDA network
• Backhaul of IP based LMR traffic
4.4 VIDAMAX NETWORK COMPONENTS/FEATURES
The basic architecture of the 4.9 GHz VIDAMAX network is a point-to-multipoint network. A system
consists of one or more base station(s) and at least one client (Figure 4-3). There are two configurations
of client devices; fixed and mobile. Fixed client devices are usually mounted outdoors with directional
antennas and have a range of up to 10 miles. Mobile clients are vehicle mounted and use an omni-
directional antenna. The range of a mobile client to base station is a few hundred meters.
18
MM-009804-001
Figure 4-4: Network diagram of small VIDAMAX system
The base station implements the 802.16-2004 protocol in a 5 MHz channel, delivering an over-the-air
throughput from 4 to 19 Mbps. All communication over this channel is scheduled by the base station,
with contention slots provided for subscriber stations to request bandwidth. This coordinated scheduling
feature of the protocol provides significant advantages such as:
• Minimizes contention between clients
• Maximizes channel utilization
• Maximizes ability to coordinate frequency usage among users
• Enables guaranteed bandwidth services for critical multimedia applications.
The use of a scheduling protocol also makes the network more resilient to simple denial of service attacks
that can disable other broadband networks.
To allow for great flexibility when designing a network, up to 16 “connections” can be established
between the base station and each client, with a different QoS for each connection. Low priority
processes (such as email) can be mapped to best effort services while high priority processes (such as
19
MM-009804-001
streaming video or LMR backhaul) can be mapped to Unsolicited Grant Services (UGS) to provide
guaranteed throughput.
4.5 4.9 GHz VIDAMAX BASE STATION
The VIDAMAX Base Station provides hardened, public safety grade base station infrastructure for M/A-
COM’s 4.9 GHz VIDAMAX broadband network. The VIDAMAX base station implements the IEEE 802.16-
2004 protocol to deliver an over-the-air throughput from 4 to 19 Mbps. All communication over the
wireless channel is scheduled by the base station, with contention slots provided for subscriber stations to
request bandwidth. Up to 16 “connections” can be established between the base station and each
subscriber in the network, with different QoS for each connection, allowing for great flexibility when
designing a network. Low priority processes (such as email) can be mapped to best effort services while
high priority processes (such as streaming video or LMR backhaul) can be mapped to unsolicited grant
services (UGS) which offer guaranteed throughput. Network convergence is provided in the form of
802.16 classifier rules that ensure network level QoS over the airlink.
Base station configuration and management is provided via a browser interface to M/A-COM’s Unified
Administration System (UAS). The base station additionally supports localized SNMP management for
single/limited site deployments. SNMP attributes are defined in the MIB II, the 802.16 and the M/A-
COM using an open MIB. Base stations may optionally be configured as DHCP and/or TFTP servers.
All subscriber station management can be performed over the air. The VIDAMAX base station provides
strong protection against unauthorized network access through the use of certificates for subscriber
authentication. Authentication keys are distributed using RSA Public Key encryption. The cryptographic
methods provided by the security sub layer use DES, 3-DES, and AES algorithms.
The VIDAMAX Base station is housed in a hardened, outdoor enclosure that satisfies IP66 requirements for
outdoor deployments. The base station is designed with flexible mounting configuration to allow for both
pole mount and fixed structure mounting. To provide for flexible RF deployment configurations, the base
station provides options for (1) direct mounting of an omni-directional antenna on the base station (2)
direct mounting of a directional antenna on the front face of the base station and (3) remote mounting of
an antenna through the connection of an RF cable to the base station. The base station comes in two
power/network configurations: one with 110 VAC power and RJ-45 Gigabit Ethernet configuration and
one with +24 VDC power and 100-BaseFX fiber configuration.

4.5.1 Summary of Key Features
4.5.1.1 Airlink Features
The VIDAMAX Base Station implements the 802.16-2004 protocol to deliver an over-the-air throughput
from 4 to 19 Mbps. All communication over the wireless channel is scheduled by the base station, with
contention slots provided for the VIDAMAX Client to request bandwidth. A protocol with coordinated
scheduling provides significant advantages such as:
• minimizing contention between clients
• maximizing channel utilization
• enabling guaranteed bandwidth services for critical multimedia applications.
The use of a scheduling protocol also makes the network more resilient to simple denial of service attacks
that can disable other broadband networks.
Up to 16 “connections” can be established between the base station and each client in the network, with
different QoS for each connection, allowing for great flexibility when designing a network. Low priority
processes (such as email) can be mapped to best effort services while high priority processes (such as
streaming video or LMR backhaul) can be mapped to unsolicited grant services (UGS) which offer
guaranteed throughput.
4.5.1.2 Network Features
Network convergence is provided in the form of 802.16 classifier rules that ensure network level QoS
over the airlink.
Network management is provided via a browser interface to M/A-COM’s UAS. The base station
additionally supports localized SNMP management using an open MIB. Base stations may optionally be
configured as DHCP and/or TFTP servers. All VIDAMAX Client management can be performed over the
air.
4.5.1.3 Security Features
The VIDAMAX base station provides strong protection against unauthorized network access through the
use of certificates for client authentication. Authentication keys are distributed using RSA Public Key
encryption. The cryptographic methods provided by the security sublayer use DES, 3-DES, and AES

4.7 VIDAMAX Base Station Antenna Options
The VIDAMAX Base Station allows users to choose many different antenna types to meet their application
requirements. Depending on the location and site planning, a directional antenna can significantly extend
the effective coverage area of the base station. For example, one can choose a high gain directional
antenna to effectively cover a long strip of highway, in the meantime avoiding the area further away from
the highway (where coverage is no longer needed) to reduce the total number of base stations. Another
example could be using a 90-degree sectional antenna to effectively cover a town-center area while
avoiding rural regions where no coverage is required. The user can directly mount an omni-directional
antenna to base station RF antenna port. Additionally, four mounting holes are provided on the VIDAMAX
Base Station chassis to allow a directional antenna to be mounted on an optional bracket. Finally, the user
can choose other industry means for mounting a directional or omni-directional antenna separate from
base station. In this case, however, the total length of cable should not exceed 5 feet. Choose high
quality 50-Ohm cable with the lowest loss at 5 GHz.
CAUTION
The four antenna mounting holes on VIDAMAX base station can sustain a pulling
force of 100 mph (160 km/h) sustained wind and survive wind gusts to 136 mph
(220 km/h). It is the user’s responsibility to estimate the force induced by antenna
to ensure the integrity of the product.
Basic Antenna Requirements:
Omni Antenna: Vertical Polarization
9 dBi Maximum Gain
Directional Antenna: Linear Vertical
26 dBi Maximum Gain
(Reduction of Transmitter Power is required if the Effective Maximum Antenna
Gain is greater than 26 dBi.)

cable that provides at least 1 dB of insertion loss. It is recommended that this antenna be installed with a minimum of 10
feet of LMR-400-UF antenna feeder cable (Cable Loss = 1.1 dB at 5 GHz). The effective Antenna Gain in this case will
thereby be less than 26 dBi. Also, due to its size, the MT-466003 needs to be individually mounted on the pole.

26
MM-009804-001
6 PLANNING THE INSTALLATION
6.1 ENVIRONMENTAL EVALUATION
Before installing the VIDAMAX Base Station, the System Engineer and installer should plan the site
selection before attempting to install the base station. Since high frequencies do not readily pass through
trees or buildings, consideration should be given to the following:
• Ensure there are no obstructions (such as buildings or trees) in the radio path between base station
and fixed client units
• Ensure the any future building construction or tree growth will not obstruct the radio path
• Ensure there is sufficient clearance around the Fresnel Zone so there is minimal interference from
obstacles along the radio propagation path
• Ensure the installation adheres to any local building codes and permits
• Ensure sufficient electrical power is available at the installation site
• When using directional antennas, align the base station antenna to maximize the received signal
strength indication (RSSI)
• Ensure area around an omni-directional antenna is clear (at least 30 inches) so as not to distort the
RF pattern
• Locate the base station away from any sources of interference that could degrade the performance
of the base station
• Ensure the base station and fixed clients are within maximum coverage range of reception
• Maximum standard CAT-5 cable length connecting the base station to the Ethernet LAN is 100
meters and maximum antenna cable length is 5-feet
6.2 POLE-MOUNT INSTALLATIONS
The VIDAMAX Base Station is designed to accommodate pole mounting. Typically, pole mounting means
mounting the base station on a light post (horizontally) or telephone pole (vertically) as shown in Figure
6-1. A kit containing two mounting brackets and hardware for attaching the base station to a pole can be
optionally purchased. The bracket accommodates mounting on a pole with a diameter in the range of one
(1) to six (6) inches. The installer must provide straps necessary to secure the base station brackets to the
pole.
CAUTION
When mounting the base station on a pole, the installer must ensure the mounting
bands are strong enough (resistance to rotation) so the base station can withstand 100
mph (160 km/h) sustained wind and survive 136 mph (220 km/h) wind gusts.
27
MM-009804-001
Figure 6-1: Pole Mounting the VIDAMAX Base Station
6.3 ELECTRICAL POWER
There are two configurations of the base station. The AC version is configured to accept 110 VAC power
from standard U.S. utility power distribution. The DC Hardened version of the base station accepts
+24 VDC (negative ground) power from a power supply or battery.
6.3.1 AC Power
An AC powered VIDAMAX base station requires at least 2 amperes of electrical service:
6.3.2 DC Power
A DC powered base station requires a +24-volt (nominal) DC power source. This source must have a
continuous-duty current rating of at least 3 amperes. Refer to Section 2, Specifications for additional
information.
6.4 SITE GROUNDING
Installers should review the recommended grounding procedures in the Site Grounding and Lightning
Protection Guidelines manual, AE/LZT 123 4618/1 and ensure a suitable ground is installed between the
base station ground lug and earth ground. Grounding must also be in compliance with any local and
national electrical codes.
28
MM-009804-001
7 INSTALLATION
The VIDAMAX Base Station resides in a Die Casting Metal Chassis to meet tough environmental
conditions. The user can choose different antenna types (omni-directional or directional) depending on
the application. It is preferred that the user specifies 50-Ohm low loss (@5GHz) cable with minimum
length (5-feet maximum) between the antenna connector and antenna port on the base station to avoid
further loss of RF power.
The base station is available as either as +24 VDC (hardened) or 110 VAC version. The total power
consumption is less than 60 Watts.
For the AC version, the radio uses weatherproof RJ-45 for connector as data and network connections.
M/A-COM recommends using the DC hardened version of the VIDAMAX base station in the areas that
experience frequent thunderstorms. In this version, weatherproof LC fiber-optic connections are
employed, and lightning protection is internally provided within the base station for the RF antenna and
DC power ports. Additional external lightning protection for the GPS antenna port may optionally be
installed.
Both the RJ-45 and LC fiber-optic connectors achieve weatherproof properties only when
properly mated with M/A-COM approved cabling. For the Service port, the dust cap is to
be installed in normal operation.
7.1 TOOLS AND TEST EQUIPMENT REQUIRED
The following tools and test equipment are recommended for installing and testing the VIDAMAX Base
Station:
• Common hand tools, including screwdrivers, wire cutters, pliers, etc.
• Modular Plug Tool, 3-231652-0 (Tyco/Electronics-AMP)
Includes; Hand Tool, 2-231652-0 and Die Set, 1-853400-0
• Digital Voltmeter (DVM), capable of measuring AC and DC voltage
• Agilent E4440A, PSA series high-performance spectrum analyzer
• Laptop Computer

• Keys and/or lock combinations to access the site and equipment shelter (if any), or points of
contact to obtain them
• Site entry alarm system pass-codes and/or disable keys
• Information about work practices needed to work safely at the site
Other important information that may or may not be included on the SDO includes:
• Type of mounting—metal pole, wooden pole, tower base, exterior wall, etc.
• Drawing or description of each site showing how the equipment is to be installed
• Applicable inspections completed (pole installation, electrical, local build code, etc.)
7.4 MOUNTING THE BASE STATION
As shown in Figure 7-1, pole-mounting brackets can be installed onto the mounting surface of the base
station so it to be mounted (a) horizontally, for instance, on the arm of a light post, or on a vertical (b)
post. In both cases, two metal straps (not included) are inserted into slots on the brackets and tightened to
the pole using industry strapping equipment.
It is important to mount the base station so that its fins are positioned vertically, as
shown in Figure 7-1 (a) and (b). This gives the base station the best thermal
performance, allowing air to move naturally through the fins
Mounting the base station with the fins vertically also allows the RF antenna port to be in the best
position for mounting the omni-directional antenna, as shown in Figure 7-1.

7.8.2 Installing a Directional Antenna
The directional antenna (weight less than 5 lb and size less than 350x350 mm^2) can be mounted on the
base station using the universal mounting bracket. This mounting bracket is located on the antenna
mounting face (cover) of the base station. The universal mounting bracket can then be adjusted to point
the beam of the antenna in the direction needed for network connectivity. An antenna weighing more than
5 lb cannot be mounted directly on the base station. A separated mounting bracket is required to mount
the antenna directly on the pole while an antenna feeder cable connects the base station to the antenna.
A low loss RF cable (not included) is needed to connect between the base station antenna connector and
the Directional Antenna.
To mount the directional antenna to the base station:
1. Using the four bolts, lock washers and flat washers included in the optional antenna mounting kit,
attach the universal antenna mounting bracket to the base station as shown in Figure 7-4.
2. Attach the antenna panel bracket assembly to the antenna panel.

9 TROUBLESHOOTING AND SERVICING
9.1 TUNING AND CALIBRATION PROCEDURE
Every VIDAMAX Base Station is fully calibrated for frequency and power before shipment to ensure
compliance with FCC requirements. No further tuning is required by the customer or installer during the
installation process.
9.1.1 Transmit Frequency Accuracy Calibration
The accurate frequency setting is a key parameter for VIDAMAX Base Station. Base station frequency
accuracy is guaranteed by a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO)
with 1.5 ppm frequency drift over full temperature range. The factory calibration procedures calibrate the
default VCTCXO setting to minimize the frequency error. This minimizes the frequency variation from
base station to base station. The base station will automatically use default value after each reboot.
9.1.2 Transmit Power Level Calibration
The power level calibration is performed at CH1, CH5, CH10 (lowest, middle, and highest) to ensure the
over-band performance. An Agilent PSA E4440A under spectrum emission mask mode is used to
perform the calibration. A standard baseband OFDM QPSK 3/4 Signal (Downlink Burst, 50% duty, 10
msec. frame) is used for the calibration. The on board 30 dB/ 1 dB step attenuator is used to adjust power
level. The cable loss (radio antenna port to PSA input) is calibrated out so the PSA can measure channel
power at the antenna port. After the TX power level calibration step, the FCC emission mask is used to
check TX spectrum at CH1, CH5 and CH10 to ensure the compliance. After calibration, the base station
uses the calibrated TX power as a default value to initialize the radio.

MM-009804-001
11 CABLE FABRICATION
11.1 ETHERNET CABLE PLUG KIT
For the AC version of the base station, the Ethernet cable connected to the base station uses a RJ-45
connector protected by an Industrial Circular Ethernet plug assembly that protects the RJ-45 connector
from the elements.
The Stranded Wire Plug Kit (Tyco Electronics # 1738607-2), shown in Figure 11-1, consists of an
8-position Category 5e RJ-45 plug, load bar, and plug assembly. The load bar is used to hold the cable
wires for insertion into the RJ-45 plug. The RJ-45 plug must be terminated and then installed into the
plug assembly. The RJ-45 plug is held in the plug assembly by the locking tab. The cable fitting holds
the RJ-45 plug in the plug assembly and seals the plug at the cable end. When engaged, the connectors
are held together by a locking mechanism (coupling ring and bayonet lock), which prevents accidental
disconnection. The engaged connectors are sealed by the interfacial seal.

11.1.2 Cable Selection
The RJ-45 plug will accept Category 5e, 100–ohm unshielded round cable with the following
specifications:
• Cable type: 8–conductor
• Conductor size: 24 AWG
• Conductor type: 7–strand copper
• Conductor insulation diameter: 0.039 in. (0.99 cm) maximum
• Cable jacket diameter range:
RJ-45 plug accepts: 0.190 through 0.220 in. (4.83 through 5.59 cm) OD (single jacket)
Cable fitting accepts: 0.18 through 0.31 in. (4.6 through 7.9 cm) OD (double jacket)
11.1.3 Cable Preparation
Prepare the cable using the following procedure:
CAUTION
Reasonable care must be taken not to scrape or nick any part of the cable during
the stripping operation.
1. Slide the plug assembly (cable fitting end first) onto the cable. See Figure 11-2, Detail A.
2. Proper strip length is necessary to insert the conductors into the contact slots. The recommended strip
length is given in Figure 11-2, Detail B.

MM-009804-001
Insulation of individual conductors must not be cut or removed. This could result in
shorted or open connections.
Figure 11-2: Cable Preparation
3. Conductor pairs must be oriented side–by–side in the order shown in Figure 11-3, Detail A. The end
of the cable jacket must be flattened so that the conductor pairs lay side–by–side.
4. Properly sequenced conductor pairs should extend into the cable jacket to the dimension given in
Figure 11-3, Detail B, creating an oblong shape.
5. The conductor tips must be trimmed evenly to the dimension shown in Figure 11-3, Detail C. Proper
orientation of conductors must be maintained.
6. The conductor pairs must be untwisted and arranged according to EIA/TIA T568A or T568B (defined
in Figure 11-3, Detail D). IT IS CRITICAL that the pairs are NOT untwisted inside the cable jacket.
When arranging conductor pairs, IT IS IMPORTANT that Conductor 6 be crossed over Conductors 4
and 5 as shown in Figure 11-3, Detail C.

11.1.4 Termination
Terminate the RJ-45 plug to the cable end using the following procedure:
1. The conductors (maintaining arrangement) must be inserted into the load bar (oriented so that the
cable notch will align with the contacts) until the cable jacket rests against the cable notch. The
conductor twist must not enter the front of the load bar. The conductors must be trimmed evenly and
square with the front edge of the load bar to the dimension given in Figure 11-4, Detail A.

MM-009804-001
2. The conductors must be retracted from the load bar so that the conductors protrude from the end of
the load bar to the dimension given in Figure 11-4, Detail B. The top of the load bar must not be
deformed.
If the load bar is deformed, the conductor twist entered the front of the load bar
3. The load bar (oriented so that the cable notch is aligned with the contacts) must be inserted into the
RJ-45 plug until it butts against the mating feature of the RJ-45 plug, and the conductors are bottomed
on the wire circuits. The cable jacket must be against the cable notch after the load bar is fully seated.
The conductors must not be exposed between the cable jacket and cable notch. The ends of the
conductors must be clearly visible through the front of the RJ-45 plug. See Figure 11-4, Detail C.
If the conductors do not bottom on the wire circuits, they must be re-trimmed (after
removing the load bar/cable assembly from the RJ-45 plug), and re-inserted into the
RJ-45 plug. If the conductors are too short, the cable must be re-stripped.
4. The RJ-45 plug must be terminated to the cable according to the instructions included with the
tooling.
11.1.5 Assembly
Assemble the RJ-45 connector into the plug assembly using the following procedures:
1. Align the locking tab of the RJ-45 plug with the wide slot at the front (end opposite the cable fitting)
of the plug assembly. See Figure 11-5, Detail A.
2. Depress the locking tab, and insert the RJ-45 plug into the plug assembly. Gently pull the cable until
the RJ-45 plug is fully seated. There should be approximately 12.7 mm [.50 in.] of the RJ-45 plug
protruding from the front of the plug assembly. See Figure 11-5, Detail B.
CAUTION
To avoid damage to the connection, the cable must be pulled GENTLY when
seating the RJ-45 plug.
3. While holding the RJ-45 plug in position, rotate the cable fitting as shown in Figure 11-5, Detail B
until tightened to a torque of 1.13 N–m [10 lbf–in.].
The given torque must be met in order for the cable fitting to seal the plug at the cable
end.
