Introduction
1.1: Manual Overview
This manual explains the installation,
setup, alignment, and maintenance
procedures for the LX Series modular
Digital VHF High Band driver/transmitter.
If your transmitter contains external
power amplifier assemblies, then
information and drawings on the external
amplifier assemblies are contained in
Volume 2. NOTE: Information on the
Axciter Modulator, the Upconverter Sled
and the Downconverter Sled are
contained in the separate Axciter Manual.
This instruction manual is divided into five
chapters and supporting appendix.
Chapter 1, Introduction, contains
information on the assembly numbering
system used in the manual, safety,
maintenance, return procedures, and
warranties. Chapter 2, system
description, maintenance and remote
control connections, describes the
transmitter and includes discussions on
system control and status indicators,
maintenance and remote control
connections. Chapter 3, site
considerations, installation and setup
procedures, explains how to unpack,
install, setup, and operate the transmitter.
Chapter 4, circuit descriptions, contains
circuit-level descriptions for boards and
board-level components in the
transmitter. Chapter 5, Detailed
Alignment Procedures, provides
information on adjusting the system
assemblies for optimal operation.
Appendix A contains drawings and parts
lists.
1.2: Assembly Designators
Axcera has assigned assembly numbers,
Ax designations such as A1, where
x=1,2,3…etc, to all assemblies, modules,

1.2: Assembly Designators
Axcera has assigned assembly numbers,
Ax designations such as A1, where
x=1,2,3…etc, to all assemblies, modules,
and boards in the system. These
designations are referenced in the text of
this manual and shown on the block
diagrams and interconnect drawings
provided in the appendices. The Block
Diagrams, Interconnects, Schematics,
Assembly Drawings and Parts Lists are
arranged in increasing numerical order in
the appendices. Section titles in the text
for assembly or module descriptions or
alignment procedures contain the
associated part number(s) and the
relevant appendix that contains the
drawings for that item.
The cables that connect between the
boards within a tray or assembly and
that connect between the trays, racks
and cabinets are labeled using Brady
markers. Figure 1-1 is an example of a
Brady marked cable. There may be as
few as two or as many as four Markers
on any one cable. These Brady markers
are read starting furthest from the
connector. If there are four Brady
Markers, this marker is the transmitter
number such as transmitter 1 or
transmitter 2. The next or the furthest
Brady Marker is the rack or cabinet
number on an interconnect cable or the
board number within a tray. The next
number on an interconnect cable is the
Tray location or number. The Brady
marker closest to the connector is the
jack or connector number on an
interconnect cable or the jack or
connector number on the board within a
tray.
