SECTION 1 General Information
1.0 INTRODUCTION
This manual contains installation, operation,
and maintenance information for the Integrated
L-Band Up/Dn Converter manufactured by
VertexRSI, Longview, Tx. Information is
organized according to section. Within each
section the pages, figures and tables are
numbered by section and by order of appearance within the section. Unless otherwise
noted, any information about the unit applies
to the LT-3600, Base Part Number 201667.
1.1 SAFETY INFORMATION
This equipment has been designed to minimize
exposure of personnel to hazards.
WWAARRNNIINNGG
A continuous safety earth ground must be
provided from the main power source
through the main power cord. This is
provided in the power cable shipped with
the unit. If this power cord is damaged, it
should be replaced with cord of equal or
better specifications. This cord can be
obtained from VertexRSI.
Servicing instructions are for use by trained
personnel only. To avoid dangerous electric
shock, do not perform any servicing unless
qualified to do so. Do not replace components
with the power cord connected to the
equipment.
WWAARRNNIINNGG
Some of the adjustments described in this
manual are performed with power applied
while protective covers are removed.
Always be careful not to come on contact
with dangerous voltages while performing
these procedures, and never work alone.
With power applied to the unit and the
cover removed, be aware that a rotating fan
is operating.
1.2 GENERAL INTRODUCTION
This manual provides operation and service
instructions for the Integrated L-Band Up/Dn
Converter. The unit consists of a power supply,
forced-air cooling system, microprocessorbased CCA (circuit card assembly) and control
circuitry and the modules required for up and
down conversion. It incorporates extensive
monitor and control functions that are
accessible from the front panel as well as
through a remote serial bus. A general
description of the front and rear panels is given
in Sections 1.5 and 1.6. A description of the
Keypad and Display can be found in Section 3.
The Integrated L-Band Up/Dn Converter is
housed in an enclosure destined for mounting
in a standard EIA 19-inch rack, requiring a
1.75-inch high vertical space.
1.3 PURPOSE OF EQUIPMENT
The Integrated L-Band Up/Dn Converter is a
fully synthesized up and down converter
covering 575 or 1000 MHz bandwidth
receiving RF frequencies in up to 125 kHz
steps. The unit incorporates extensive monitor
and control functions that are accessible from
the front panel as well as through a remote RS232/422/485 bus.
The LT-3600 can be configured to
accommodate various requirements involving
an IF of 70 or 140 MHz, non-inverted or
inverted spectrum, with standard or highstability 10 MHz reference oscillator or any
combination the user desires. Combined with
jumper selectable and user programmable
options, the LT-3600 is flexible to user
requirements.

1.4 SPECIFICATIONS
The specifications for the Integrated L-Band
Up/Dn Converter are listed in Table 1-1, along
with the mechanical dimensions.
1.5 FRONT PANEL
All the operating controls and indicators for the
Integrated L-Band Up/Dn Converter are
located on the front panel. The front panel is
depicted in Figure 1-1. Alarm and level
monitoring of the L-Band Up/Dn Converter
CCA, an external LNB, and SSPB modules is
accomplished through the front panel display
and keboard interface.
1.6 REAR PANEL
The rear panel is depicted in Figure 1-2. It
incorporates, from left to right, Grounding Lug
(GND), Power Connector, Optional 10MHz
high stability reference output (J1), 10 MHz
(J4), On/Off Switch for Dc output on J4
(SW2), Cooling Fans, Down Converter
StarSwitch Interface (Opt.) (J5), SSPB monitor
and control (J6), Remote Serial Interface (J7),
Up Converter StarSwitch Interface (Opt.) (J8),
IF In (J9), On/Off Switch for Dc output on J10
(SW3), L-Band Out (J10).
In the lower right hand side of the rear panel is
a label that refers to the operation and
maintenance manual and revision level that
applies to this converter.
1.7 COOLING
Cooling of the equipment is achieved by
pulling in cool air through the two side inlet
grills. The heated air exits the equipment
through the two rear panel mounted exhaust
fans.

1.8 Part Number Configuration
The Part Number Selection Chart shows configuration options that are set at the factory prior to
shipment. The voltage output to J4 and J10 may be changed as required by the customer, however
this requires removal of the cover and resetting internal jumper connections. This should be
performed by qualified personnel.
