Asse bly Designators
Axcera has assigned assembly numbers, Ax designations such as A , where x= ,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 markers. Figure is an
example of a marked cable. There may be as few as two or as many as four Markers on
any one cable. These markers are read starting farthest from the connector. If there
are four Markers, the marker farthest from the connector is the system number such as
system or transmitter 2. The next or the farthest Marker is the rack or cabinet “A”
number on an interconnect cable or the board “A” number when the cable is within a
tray. The next number on an interconnect cable is the Tray location or Board “A”
number. The marker closest to the connector is the jack or connector “J” number on an
interconnect cable or the jack or connector “J” number on the board when the cable is
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
. 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.

The Innovator CXB Series systems are 7” (43.2cm) wide standard rack mountable trays.
They are supplied with side mounted Tray Slides for ease of installation and removal. The
CHV200 system is 3 RU, 5.25” ( 3.3cm), high. The CHV400 and CHV500 systems are 9 RU,
5.75” (40cm) high, which is 3 RU, 5.25” ( 3.3cm) for the driver and 6 RU, 0.5” (26.7cm)
for the 400 watt Innovator CHVB Series amplifier tray. The CHV 000 systems are 5 RU,
26.25” (66.7cm) high, which is 3 RU, 5.25” ( 3.3cm) for the driver and 2 RU, 2 ” (53.4cm)
for the two Innovator CHVB Series amplifier trays. The CHV 500 systems are 5 RU, 26.25”
(66.7cm) high, which is 3 RU, 5.25” ( 3.3cm) for the driver and 2 RU, 2 ” (53.4cm) for the
two Innovator CHVB Series amplifier trays. The CHV2000 systems are 2 RU, 36.75”
(93.3cm) high, which is 3 RU, 5.25” ( 3.3cm) for the driver and 8 RU, 3 .5” (80cm) for the
three Innovator CHVB Series amplifier trays. The CHV3000 systems are 27 RU, 47.25”

AC Input Connections
The CHV200B single tray systems will operate with an input voltage of 85-253VAC. The
customer should provide a single point disconnect for the main AC input connection to the
transmitter. Check that the AC switch, located on the rear of the tray above the AC power
jack, is OFF. Connect the AC power cord supplied with the tray from J6 on the rear of the
tray to the AC source. If your system has the optional ASI to S3 0 Converter, check that it
is connected to the AC source.
If your system is a CHV400B or CHV500B, it also contains one amplifier tray. In CHV 000
and higher power systems, multiple amplifier trays are included. Each amplifier tray is
configured for 230 VAC operation only. Check that the ON/OFF circuit breaker or circuit
breakers in the amplifier, located on the rear panel on either side of the AC power jack, are
OFF. Connect the AC power cord supplied with the tray from J 0 on the rear of the tray to
the 230 VAC source. Refer to Table for the typical voltage and current requirements for
CHVB Systems.
If the system is mounted in a rack, an AC distribution box wired to a quad receptacle box is
used to connect the AC to the individual trays. The AC distribution box is mounted on the
upper right side of the rack accessed through the back of the rack. The main AC input for a
CHXBTD transmitter is, 95-235VAC, at least 0Amps, 50/60Hz. The customer should
provide a single point disconnect for the main AC input that connects to the transmitter. The
AC input lines connect inside the AC distribution box by first removing the two screws that
hold the cover plate to the front of the AC distribution box. Then connect the three wire main
AC input to the input lugs, L to L , L2 to L2 and Ground to Ground. The power amplifier tray
and the quad receptacle box connect through AC power cords directly to the AC distribution
box. The AC power to the optional receiver tray and the exciter/driver tray are connected
through AC power cords that plug into the quad receptacle box.
If the system is mounted in a cabinet, an AC distribution panel is supplied to connect the AC
to the individual trays. The AC distribution panel is mounted facing the rear of the cabinet
and accessed through the back of the cabinet. The main AC input for a CHV 000BTD
transmitter is, 95-235VAC, at least 30Amps, 50/60Hz. The customer should provide a single
point disconnect for the main AC input that connects to the transmitter. The AC input lines
connect to the AC distribution panel by first removing the four #8 screws that hold the cover
plate to the front of the AC distribution panel. Then connect the three wire main AC input to
the input lugs located at the top left of the AC distribution panel, L to L , L2 to L2 and
Ground to the Ground lug on the left. The AC distribution panel in a CHV 000BTD has three
circuit breakers that distribute the AC to the individual trays, which are the Exciter and the
two power amplifier trays. The circuit breakers, which are accessed through the rear door of
the cabinet, supply the AC though AC line cords, that connect to the AC input jacks mounted
on the rear panels of the trays. CB is a 30 Amp circuit breaker which supplies the AC to the
(A2), top, Power Amplifier A tray. CB2 is a 30 Amp circuit breaker which supplies the AC to
the (A3), bottom, Power Amplifier B tray. CB3 is a 0 Amp circuit breaker which supplies the
AC to the (A ) Exciter/Driver tray. A maximum of four 30 Amp circuit breakers for four
amplifier trays and two 0 Amp circuit breakers for two Exciter/Driver trays can be installed in
the AC Distribution Panel.

In Translator (BRD) systems there is a SMPTE-3 0 loop-thru from the output of the
Demodulator Board at J4, mounted on the rear panel of the transmitter or driver tray, to
the input to the Modulator Board at J5, mounted on the rear panel of the transmitter or
driver tray. There is a jumper installed from J4 to J5. To feed SMPTE-3 0 directly to the
Modulator Board, remove the jumper and insert SMPTE-3 0 into J5. This is only used in
Translator (BRD) systems not Transmitter (BTD) systems.
The digital RF ON Channel output of the CHV200B and the driver tray for CHV400B and
higher power systems is at J9 the 50Ω “N” connector RF output jack located on the rear
panel. In the CHV200B system the output of the tray at J9 connects to the low pass, digital
mask filter and then to the antenna for your system. In CHV400B and higher power
systems the output of the driver tray at J9 is connected to J the 50 Ohm “N” connector RF
input jack located on the rear panel of the 500 Watt, 750 Watt, kW amplifier tray or to a
splitter in multiple amplifier systems. In CHV200B systems, check that the system power
metering interface cable is connected from J 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 amplifier tray. This cable provides the control, status and operating parameters of the
amplifier tray to the driver tray. In CHV 000B or higher power systems, the output of the
driver tray is split and connected to J the “N” type connector RF input jack on the amplifier
trays. Check that the system power metering interface cable is connected from J the 9
position “D” connector located on the rear panel of the driver tray to J9 the 9 position “D”
connector located on the System Metering Board. Also check that the serial connection is
cabled from the RJ-45 connector J 3 on the driver tray to the RJ-45 connector J on the
system metering board. The system metering board provides serial RJ-45 connections at J2
and J5 that are cabled to the RJ-45 serial port J5 on the rear panel of the amplifier trays.
These cables provide the control, status and operating parameters of the amplifier trays to
the driver tray through the System Metering Board.
The digital RF ON Channel output of the amplifier tray is at J2 the 50Ω “7/ 6” ( . cm) Din
connector RF output jack located on the rear panel that connects directly to the digital mask
filter, the low pass filter and then to the antenna for your system in single amplifier
systems. In multiple amplifier tray systems the outputs of the trays connect to a combiner
and then the digital mask filter, the low pass mask filter, the output coupler and finally to
the antenna for your system. The output coupler provides a forward and a reflected power
sample that are cabled to the System Metering Board at J8 reflected and J3 forward. Also
connected to the system metering board at J 0-6 & 9, is the output of the overtemperature
switch mounted to the reject load that is used as the reject interlock by the system. The
samples and interlock are fed through J9 on the system metering board to J on the driver
tray.
This completes the connections of the system.
