INSTALLATION PROCEDURE

UNPACKING

Please inspect all material thoroughly upon arrival. Axcera certifies that upon leaving our facility the
equipment was undamaged and in proper working order. The shipping container should be inspected for
obvious damage indicative of rough handling.

Remove the unit(s) from the shipping container and inspect for damage. Check for dents, and scratches, or a
broken switch, meter or connector. Remove the top cover of the unit and again inspect for shipping damage.
Extract all packing material from inside and around the unit. Check for loose hardware and connectors,
retighten if needed. Any claims against in-transit damage should be directed to the carrier. Save all packing
material in case it is needed in the future.

INSTALLATION OF TRAY(S)

í Units are shipped with chassis slides mounted to the each side. Included in the Installation Material Kit

are two cabinet mount slide assemblies that will be mounted in the rack. Install the Tray slides into the
cabinet. Refer to the "Cabinet Mounting Instructions Slides Drawing" which follows, for detailed
instructions.

í Slide the unit into the cabinet. If it does not slide in and out smoothly, some adjustment is necessary.

Pull out the unit (only enough for clearance) and loosen the hardware holding the cable slides to the
cabinet. Move the front of the Tray up or down or side to side to remove the rubbing. Retighten the
hardware after the adjustment is complete.

í Also included with the unit is a cable retractor assembly, which consists of two parts, a cabinet mount

retractor and a tray mount retractor.

n The cabinet mount retractor has a long aluminum channel hinged to a mounting piece with two bolts.

This is mounted to the rear of the left hand, facing the front of the unit, cabinet mount slide assembly.

n The retractor is a short aluminum channel hinged to a slide mount. This piece slides into a receptacle

mounted to the rear panel of the unit.

These cable retractors work together to move the wire harness and coaxial cables in and out with the movement
of the unit to avoid pinched wires.

í After the units(s) are physically in place, the process of interfacing them into the system begins by

making connections to the back of the units.

CONNECTIONS

Once all equipment is in place, making connection to the back of the tray (s) is a relatively simple process.
Each wire is clearly marked with a number corresponding to the tray where it connects.

NUMBERING

The numbering system used on wires that connect to the back of the trays is as follows:

FIRST NUMBER - Channel designator

SECOND NUMBER - Connector on back of tray

EXAMPLE: A wire marked 2 10 would go to channel 2 in the group, connector J10

Finally, verify that AC power (J1) is connected to each unit. Once this is complete, proceed to the initial turn
on procedures.

NOTE: All Axcera products are designed for operation with either 115VAC or 208/230 VAC, 50/60 Hz
input. Systems are shipped from the factory properly configured for the standard of the country of destination.

SYSTEM DESCRIPTION

FREQUENCY GENERATOR TRAY

The Frequency Generator tray is configured to control multiple VCXO’s. within the 4 Channel VCXO
assembly. The selected VCXO output is sent to the VHF Buffer/Combiner Board where the RF signal is
amplified. The output of the VHF Buffer/Combiner Board is multiplied by four and filtered, then processed
by the PLL Board. Once again the signal is multiplied and filtered producing an L.O. output to the agile
upconverter. A liquid crystal display on the front panel provides access to various menus through the use of
five soft touch keys.

10-WATT AGILE UPCONVERTER/AMPLIFIER

The 10-Watt Agile Upconverter/Amplifier accepts an input signal of +25 to +35 dBmV and is compatible
with any QAM signal up to 256 and VSB up to 16. Operating frequency range is from 2572-2614 MHz.
The signal is processed through the unit in a similar manner to that of an analog system with IF circuitry
performing ALC, frequency response and delay correction as well as linearity correction. The RF signal is
sampled, peak detected, and fed to a control amplifier before being connected to the output of the tray.

INITIAL TURN ON 5543A DIGITAL AGILE PAGE 4

INITIAL TURN ON

Prior to turning on the system, be sure all connections are in the correct place, and AC power is connected
to the back of each tray. Next, follow the steps below:

í Turn on each circuit breaker (CB1) located on the back of each unit beginning with the AC
Distribution Panel.

í Verify that each unit is in standby mode. Upon initial turn on, the following LED indicators should
be on.

FREQUENCY GENERATOR

- Operate and fault LED should flash twice and then go off.

UPCONVERTER.AMPLIFIER

-PLL LOCKED

-IF INPUT PRESENT

-THERMAL INTERLOCK

-EXTERNAL 10 MHz PRESENT (optional)

í After verifying that each unit is in standby mode and that the initial turn on LED indicators are
on, press the OPR softkey located on the front of the Frequency Generator Tray. The following
additional indicators should light:

FREQUENCY GENERATOR

-OPERATE

UPCONVERTER/AMPLIFIER

-ENABLE

-SWITCHING SUPPLIES

í IN THE EVENT ANY RED LED’s ARE ON, RETURN THE UNIT TO STANDBY MODE AND
CONTACT AXCERA SERVICE IMMEDIATELY.

OPERATION 5543A DIGITAL AGILE PAGE 5

UNIT OPERATION

Located on the front of the Frequency Generator Tray are soft-keys and a liquid crystal display. Four menu
screens are available: status, mode, fault, and channel setup. Initially when the unit is turned on, a title
screen appears which displays the company logo, address, and phone number.

Next, the status screen appears as follows:

STATUS: STANDBY
CHANNEL : A1
MANUAL MODE
PRV DWN UP OPR NXT

The first line displays the status of the system. To change from standby to operate, press the OPR button.
The unit will switch to operate mode. Displayed on the second line is the channel the frequency generator is
tuned to. To scroll through the channels press the DWN or the UP key. The channel menu is only available
in standby mode.

From the status screen press the NXT key. The display will then read as follows:

MODE SELECT
STATUS : STANDBY
MANUAL MODE
PRV AUT NXT

This menu allows easy switching from manual to automatic mode. In order to make any changes in channel
setup, the unit must be in manual mode. Automatic mode runs through a continuos loop checking for faults
detected by the ABS (Automatic Backup System), which will detect any problems and send the appropriate
information to the Frequency Generator.

Once again, press the NXT key. This will access the fault menu:

FAULTS : 0

NONE

PRV CLR NXT

Displayed on the first line is the total number of faults (if any) and a specific list of the particular fault (s).
Scroll through the list by using the DWN and UP key. The CLR key is used to clear the fault from the
display, but if the fault condition remains, the message will return.

Finally, a channel setup is available. The unit must be in standby to make any changes.

CHANNEL SETUP
CHANNEL : A1 (AVAIL)

PRV DWN UP UNAV NXT

The UP and DWN key will scroll through the available channels and indicate if that particular channel is
available or unavailable. Press the UNAV key to change which channels are available and unavailable.
