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.
