Safety Considerations
This product and manual must be thoroughly understood
before attempting installation and operation. To do so
without proper knowledge can result in equipment failure
and bodily injury.
Caution: Before applying ac power, be sure that the
equipment has be properly configured for the available
line voltage. Attempted operation at the wrong voltage
can result in damage and voids the warranty. See the
manuals section on installation. DO NOT operate equipment
with cover removed.
Earth Ground: All Datron products are supplied with a
standard, 3-wire, grounded ac plug. DO NOT attempt to
disable the ground terminal by using 2-wire adapters of
any type. Any disconnection of the equipment ground
causes a potential shock hazard that could result in personal
injury. DO NOT operate any equipment until a suitable ground
has been established. Consult the manual section on ground-
ing.
Servicing: Trained personnel should only carry out servicing.
To avoid electric shock, DO NOT open the case
unless qualified to do so.
Various measurements and adjustments described in this man-
ual are performed in ac power applied and the protective
covers removed. Capacitors (particularly the
large power supply electrolytics) can remain charged for
a considerable time after the unit has been shut off. Use
particular care when working around them, as a short circuit
can release sufficient energy to cause damage to the equipment
and possible injury.
To protect against fire hazard, always replace line fuses
with ones of the same current rating and type (normal
delay, slow-blow, etc.). DO NOT use higher value
replacements in an attempt to prevent fuse failure. If
fuses are failing repeatedly this indicates a probable
defect in the equipment that needs attention.
Use only genuine Datron factory parts for full performance
and safety of this product.

CHAPTER 2
INSTALLATION
This section contains information necessary to install the RT7000 in its
operating environment. Power, antenna, and accessory connections are
discussed. System diagrams are provided to show the proper connections to a
variety of accessories.
Unpacking and Inspection
When unpacking the RT7000, carefully remove the equipment from its
container and inspect it for any possible damage. If anything is damaged, notify
Datron. Check the equipment against the packing list. Save the original
container and packing materials for storage or reshipping purposes.
Location Considerations
The RT7000 can be deployed successfully in various locations, in a number of
different configurations, depending on whether remote or extended control is
used. Information in this section pertains to the main body of the RT7000,
whether it is controlled locally or from a remote site.
Fixed Station Unless otherwise specified when ordered, the RT7000 is shipped ready for
operation. It is also available for mounting in a rack, provided the appropriate
rack kit is ordered.
Make sure the temperature at the location is within the specified range, and that
there is adequate ventilation around the rear of the RT7000 to allow for air flow.
The RT7000 has a rear panel heat sink to dissipate heat that is generated from
the power amplifier during transmission. The RT7000FAN-1 external option
provides continuous cooling when conditions require heavy use.
To prevent unwanted noise, locate the RT7000 as far away as possible from
electrostatic and magnetic field-generating equipment.
When attaching external cables to the RT7000, allow for sufficient slack in the
cables. This prevents damage from sharp bends and ensures easy disconnection.
Vehicular or
Marine
Use the mobile mount to mount the RT7000. It may be necessary to fabricate
special supplementary brackets to complement a particular vehicle or shipboard
location. Datron offers rack, mobile, and shock mount kits for the RT7000,
suitable for most installations.

RT7000-MSOP 2-3
Rear Panel Connections
The rear panel of the RT7000 is made of die cast aluminum and is attached to
the rear side panels by 4 hex head bolts. The heat sink maintains the
temperature within operational specifications eliminating the need for an
internal cooling fan. It fills most of the rear panel area leaving room for the
fan power connector and optional pre/postselector RF connections.
The accessory, remote control and RF connections are wired to the Interface/
Power supply board.
Power to the
RT7000
Input power for the RT7000-12 is nominally 13.8 Vdc, with a maximum
current requirement of 25A. The recommended operational voltage range of
the transceiver is 11 to 15.5 Vdc. The RT7000-28 requires +28 Vdc at a
maximum of 15A (range of 22-30 Vdc). The DC input connector on the rear
panel is a 2 pin, 30A circular receptacle that has a square mounting flange
with 2 male pins. The mating plug is attached to the input DC power cable
(C991556). This cable, supplied with the RT7000, has a convenient
connection to a variety of DC power sources. For specific connections, refer
to the "Power Cabling Accessories" figure on page 2-6.
The DC power connection between the RT7000 and its power source should
be as short as possible. If a Datron power cable is not available, use a 14 AWG
cable for runs up to 3 feet, a 12 AWG cable for runs to 9 feet, or a 10 AWG
cable for longer runs.

2-4 RT7000-MSOP
Two DC power supplies are available from Datron when a +12 or +28 Vdc
primary power source is not available:
UPF7000A-12 Heavy duty power supply permits continuous duty opera-
tion. Runs off 84-240 VAC, 50/60 Hz and requires a
C991511 cable.
UPF7000A-28 Heavy duty power supply permits continuous duty opera-
tion. Runs off 84-240 VAC, 50/60 Hz and requires a
C991511 cable.
The waterproof fuse holder (pin 630005) on the rear panel contains either a
25A (12V), 3-AG fuse or 15A (28V), 3-AG fuse.
Antenna
Connection
The RT7000 is designed to work into a 50 ohm RF impedance. The output RF
antenna connector is a type N connector. Broadband antennas and dipoles can
be connected directly to this output, while high-power amplifiers and antenna
tuners use specially-designed Datron cables. For specific connections, refer to
the "RF Cabling Accessories" figure on page 2-7.
External Fan
Connection
The external fan cooling kit (RT7000FAN-1) mounts on the back of the
heatsink and is mandatory for light duty cycle HF data applications.
Accessory
Connections
A variety of external accessories are available from Datron for use with the
RT7000. For some of these accessories and their control cabling, refer to the
"Control Cabling Accessories" figure on page 2-8. For more information on
any individual accessory, refer to the manual for that piece of equipment.
There are three accessory connectors on the rear panel, each with different pin
assignments. If multiple accessories are required that share one or more of the
accessory connectors, an external accessory combiner box (RT7000IOX) can
be attached to any of these connectors. Each of the three connectors on the
rear panel is a circular MIL-C with 26 pins. For the location of these
connectors, refer to the "Rear Panel Connections" figure on page 2-3.
External
Encryption
Using the 7000ENCR option, the RT7000 allows provision for an embedded
encryption board. External encryption can also be used with the RT7000 and
connected to Accessory 1 or Accessory 2.
Telephone
Couplers
Telephone couplers like the RT5810 or RT5850 use either Accessory 1 or
Accessory 2.
EIA Data
Interface
Standards
The RT7000 interfaces with a variety of data communications equipment
(DCE) or data terminal equipment (DTE) using EIA standards RS232, RS422
or RS485. Accessory 1 is configured to provide the standard I/O port (COM1)
for these interfaces. The RS232 protocol is standard; all others are optional. It
is necessary to order the 7000RS option and to specify the required protocol
so the appropriate interface chip is inserted into the processor.

2: Installation
RT7000-MSOP 2-5
If the 7000RS option is installed, the COM1TXD and COM2RXD becomes a
2-wire bidirectional RS422/485 interface.
A 3-wire RS232 interface is also available on Accessory 2.
Automatic
Antenna
Tuners
The RT7000 interfaces with the complete line of Datron automatic antenna
tuners. This includes the older AT/RAT100 and RAT1000 as well as the newer
AT/RAT7000B and RAT1000B.
The AT/RAT100 and RAT1000A and RAT1000C connect to Accessory 2. The
AT/RAT7000 uses Accessory 3.
Data Terminal
Interface
The RT7000 interfaces with its own line of data terminals or to other external
units using Accessories 1 and 2.
External
Printers
A standard parallel printer connects to Accessory 1 to obtain a hard copy of
text messages stored in the RT7000.
ALE/Transcall/
Selcall Alarm
The external ALE/Transcall/Selcall alarm driver is available on Accessory 2.
External
Speaker
An external speaker attaches to the RT7000 at Accessory 2.
External
High-Power
Amplifiers
The RT7000 interfaces with all existing Datron high-power RF booster
amplifiers using Accessory 3.
