Introduction

Manual Overview

This manual contains the description of the Innovator CU5-1800BTD/BRD ATSC
Transmitter/Regenerative Translator and the circuit descriptions of the boards, which
make up the system. The manual also describes the installation, setup and alignment
procedures for the system. Appendix A of this manual contains the system level
drawings for the Innovator CU5-1800BTD/BRD ATSC Transmitter/Regenerative
Translator. NOTE: Information and drawings on the Axciter, if part of your system, are
contained in the separate Axciter Instruction Manual.

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 diagram and interconnect drawings
provided in Appendix A.

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 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 system number such as
system 1 or translator 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.

EMERGENCY FIRST AID INSTRUCTIONS

Personnel engaged in the installation, operation, or maintenance of this equipment are
urged to become familiar with the following rules both in theory and practice. It is the
duty of all operating personnel to be prepared to give adequate Emergency First Aid and
thereby prevent avoidable loss of life.

RESCUE BREATHING

1. Find out if the person is
breathing.

You must find out if the
person has stopped breathing.
If you think he is not
breathing, place him flat on
his back. Put your ear close to
his mouth and look at his
chest. If he is breathing you
can feel the air on your
cheek. You can see his chest
move up and down. If you do
not feel the air or see the
chest move, he is not
breathing.

2. If he is not breathing,
open the airway by tilting his
head backwards.

Lift up his neck with one
hand and push down on his
forehead with the other. This
opens the airway. Sometimes
doing this will let the person
breathe again by himself.

3. If he is still not breathing,
begin rescue breathing.

-Keep his head tilted
backward. Pinch nose shut.

-Put your mouth tightly over
his mouth.

-Blow into his mouth once
every five seconds

-DO NOT STOP rescue
breathing until help arrives.

LOOSEN CLOTHING - KEEP
WARM

Do this when the victim is
breathing by himself or help
is available. Keep him as
quiet as possible and from
becoming chilled. Otherwise
treat him for shock.

BURNS

SKIN REDDENED: Apply ice cold water to
burned area to prevent burn from going
deeper into skin tissue. Cover area with a
clean sheet or cloth to keep away air. Consult
a physician.

SKIN BLISTERED OR FLESH CHARRED:
Apply ice cold water to burned area to
prevent burn from going deeper into skin
tissue.

Cover area with clean sheet or cloth to keep
away air. Treat victim for shock and take to
hospital.

EXTENSIVE BURN - SKIN BROKEN: Cover
area with clean sheet or cloth to keep away
air. Treat victim for shock and take to
hospital.

exterior damage and make note of any dents, broken seals, or other indications of
improper handling. Carefully open each package and inspect the contents for damage.
Verify that all materials are enclosed as listed on the packing slip. Report any shortages
to Axcera. In the event any in transit damage is discovered, report it to the carrier.
Axcera is not responsible for damage caused by the carrier. If the equipment is not
going to be installed immediately, return all items to their original packaging for safe
storage. Save all packing material for future use. If equipment is ever removed from
the site, the original packaging will ensure its safe transport.

Installation

The Innovator CXB Series systems are designed for simple installation. Expensive test
equipment is not required for installation and set up and to keep a system operational.
Prior to installing the product, review the following items. Check that they have been
installed, tested and/or inspected.

Building Structure

Refer to Figures 3 and 4, and Tables 2 and 3 for detailed information on the jacks and
connectors. Connect the On Channel RF Input (BRD), –78 to –8 dBm, or the SMPTE-310
Input (BTD), to the 50Ω BNC input jack J1, located on the rear panel of the CU5 thru
CU125 systems and the driver trays for the CU250 and higher power systems.

If used, connect the external 10 MHz reference input to the 50Ω BNC 10 MHz input jack
J6 located on the rear panel of the CU5 thru CU125 systems and the drivers for the
CU250 and higher power systems. If used, connect the external 1 PPS reference input
to the 50Ω BNC 1 PPS input jack J7 located on the rear panel of the CU5 thru CU125
systems and the drivers for the CU250 and higher power systems.

The digital RF ON Channel output of the CU5 thru CU125 systems and the driver trays is
at J9 the 50Ω “N” connector RF output jack located on the rear panel. In CU5 thru
CU125 systems, the output of the tray at J9 connects to the digital mask filter and then
to the antenna for your system. In CU250 and higher power systems, the output of the
driver tray at J9 is connected to J1 the 50 Ohm “N” connector RF input jack located on
the rear panel of the 250 Watt, 500 Watt amplifier tray or to a splitter in multiple
amplifier systems. Check that the system power metering interface cable is connected
from J11 the 9 position “D” connector located on the rear panel of the driver tray to J4
the 9 position “D” connector located on the rear panel of the 250 Watt or 500 Watt
amplifier tray. This cable provides the control, status and operating parameters of the
amplifier tray to the driver tray. The digital RF ON Channel output of the amplifier tray
is at J2 the 50Ω “7/16” (1.1cm) Din connector RF output jack located on the rear panel
that connects directly to the low pass filter, the digital mask filter and then to the
antenna for your system in single amplifier systems or to a combiner and then the low
pass filter, the digital mask filter and finally to the antenna in multiple amplifier systems.

Regenerative Translator Turn On Procedure

Initial On Site Turn On Procedure

After the Innovator CXB Series tray or trays are installed and all input, output and AC
connections are made, the system is ready for the initial on site turn on. Check that the
output of the CU5, CU30, CU50, CU100, or CU125 tray is connected to an appropriate rated
load or to the digital mask filter and the antenna for your system. If your system is a CU250
or higher power system, check that the output of the amplifier tray or the combiner assembly
is connected to an appropriate rated load or to the low pass filter, the digital mask filter and
the antenna for your system. Check that the main AC power to the System is ON.

If you have a CU5, CU30, CU50, CU100 or CU125 system, push ON the switch located on the
rear panel of the tray above the AC power jack. The large fan mounted on the rear panel of
the tray should operate. If your system is a CU250 or higher power system, switch ON the
ON/OFF circuit breakers located on the rear panel of the amplifier tray(s) mounted on each side
of the AC input power jack. The two fans mounted in the amplifier tray should operate.

The Operate/Standby LED and Status LEDs on the CU5, CU30, CU50, CU100 or CU125 should
be Green indicating the system is in Operate and performing normally. The Operate/Standby
LED showing Amber indicates the System is in Standby. The Status LED showing a blinking Red
LED indicates a Fault is occurring now. The Status LED showing Amber indicates that a Fault
occurred since the last time the Fault indications were reset.

If your system is CU250 or higher power, the Enable LED and Status LEDs on the 250 or 500
Watt Amplifier Tray should be Green indicating the system is in Operate and performing
normally. The Enable LED showing Amber indicates the System is in Standby. The Status LED
should be Green indicating no faults in system. If the Operate/Standby LED shows Amber it
indicates that the System is in Standby. If the Status LED is blinking Red it indicates a Fault is
occurring now. If the Status LED shows Amber it indicates that a Fault occurred since that last
time the Fault indications were reset. The output power is factory set according to customer
request and does not need adjusted. If a problem occurs, call Axcera field support at 1-724­873-8100 for information on modifying the power level of the system.

NOTE: The RF System Interlock is provided on J12, a D connector, located on the rear panel

of the CU3, CU30, CU50, CU100 or CU125 tray. The RF System Interlock at J12-5
provides the customer with a means of connecting the system to protection circuits,
for the loads, thermal switches, combiners, or the antenna, in the output of your
system, that will place the system in Standby if the protection circuit opens. The
Reject Load Interlock at J11-6 provides the customer with a means of connecting the
system to protection circuits, for the reject load in multiple amplifier systems, which
will place the system in Standby if the protection circuit opens. If the interlocks are
not used in your system, a plug with a jumper from J11-5 to J11-9, ground, for RF
system Interlock and another plug with a jumper from J11-6 to J11-9, for Reject Load
Interlock, need to be connected. These jumpers provide the RF System and Reject
Load Interlocks, which allow the system to go to operate. Without the jumpers, the
system will remain in Standby.
