Using This Manual
This manual details installation and checkout procedures for the All Weather, Inc. Automated
Weather Observing System (AWOS) 3000. The AWOS 3000 is available in multiple configura-
tions, with each AWOS configuration having a unique suite of sensors. This manual is organized
around the individual sensors, with each sensor covered in its own chapter. A table at the
beginning of each chapter lists the AWOS configurations that include the sensor.
The first two chapters cover installation and checkout of the Central Data Processor (CDP) and
Data Collection Platform (DCP), which are included in all systems. The remaining chapters
cover the installation of the sensors and their accessories.
Detailed installation drawings and wiring diagrams are provided in Chapter 17, Drawings.
Checkout procedures are provided for each sensor or component. These are intended to verify
operation when a sensor or component is replaced in an existing system. When a complete
system is installed, checkout is accomplished by performing the Annual System Revalidation
procedure described in the AWOS 3000 Maintenance Manual (3000-027).
1.1 General Precautions
Note that ultraviolet-resistant cable ties must be used whenever cable ties are called for.
Note that the metallurgy of the stainless U-bolts will cause the nuts to seize to the U-bolts and
twist them off. Lubricate the threads with anti-seize compound before assembling.
Electrostatic discharge (ESD) precautions must be followed when working with printed circuit
boards and wiring the data interfaces. At a minimum, wear a grounding wrist strap and connect
the ground to a chassis ground inside the enclosure you are working in.
Observe basic electrical safety procedures such as turning the power or circuit breaker off when
working with the AC power interfaces.
All test and calibration equipment must be traceable as specified by the National Institute of
Standards or other standards organizations where specified.

2.1 CDP Installation
The CDP is self-contained. It is installed indoors, at a location with access to AC power and any
auxiliary communication and data lines required. Installation of the CDP primarily involves
routing external cables into the CDP rack and connecting them to the CDP back panel. The
installation of individual CDP options (AWOS Net, UHF Radio, etc.) is covered later in this
chapter in the sections devoted to those options.
The CDP is a 22" × 20.5" × 20" 11RU small equipment rack that weighs 138 pounds. The CDP
must be place in a stable location for its size and weight.
Drawing 3000-019 in Chapter 17, Drawings provides the CDP wiring diagram for reference.
2.1.1 Back-Panel Connections
Connections to external devices and data sources (such as the AWOS DCP, ADAS, GPS NTP
server, and printer), as well as internal components (such as VHF Radio and Modem) are made
at the back panel. The back panel is located inside the CDP rack, just above the bottom shelf (see
Figure 8). Figure 2 shows the back panel connectors.
Figure 2. CDP Back Panel Connectors (front end)
External cables are routed to the back panel through an access hole located in the right rear
corner at the top of the rack enclosure.
2.1.2 Connecting Power
Power is supplied to the CDP through the UPS housed in the base of the CDP rack. A power
cord is included and installed, and is routed through the access hole in the top of the CDP
enclosure. Connect this power cord to a suitable AC outlet.
2.1.3 Connecting the VHF Antenna
The VHF antenna and antenna cable must be installed. A mast for the antenna should have been
installed as part of the site preparation. The cable from the VHF Ground-to-Air (GTA) radio
antenna must be routed to the CDP rack and connected to the back panel.
1. Using the radiator length chart on the UHF/VHF Antenna Assembly instructions
(included with the VHF antenna and also in Chapter 17, Drawings), find the optimum
radiator length for the VHF radio frequency.
Note that the radiator lengths remain unchanged from the provided length for standard
VHF GTA frequencies used for AWOS systems.

2. Using a hacksaw, trim the radial length of the antenna (Part M489103) to the length
specified. Cover the end of the radiator with the plastic end cap provided with the
antenna.
3. Coat the threaded ends of the radials with PTFE lubricant (supplied with antenna). Attach
the radials to the radiator section.
4. Coat the threaded portion of the U-bolt with PTFE. Attach the U-bolt to the antenna as
shown.
5. Coat the threaded portion of the radiator with PTFE. Attach the completed antenna to the
U-bolt mount as shown.
6. Attach the antenna to the mast installed on the building for the VHF radio antenna.
7. Attach the VHF radio antenna cable (Part M491361) UHF connector to the antenna.
8. Route the antenna cable to the CDP location.
9. Do not trim the antenna cable before you attach the BNC connector to the antenna cable
since shorter antenna cable lengths mean less signal loss, and this translates to an
increased effective radiated power by the antenna, which may then exceed regulatory
specifications. Figure 3 shows how to attach the BNC connector to the antenna cable.
10. Connect the cable to the BNC connector labeled VHF on the front side of the back panel.
Figure 3. BNC Connector Installation

2.1.4 Connecting Optional Printer
A parallel port is available on the CDP back panel for connection to a printer. Connect the printer
as follows:
1. Connect the Centronics 36 end of the parallel printer cable (Part 20912-A) to the printer
cable connector on the printer.
2. Feed the printer cable through the access hole in the top of the CDP enclosure.
3. Connect the other end of the printer cable to the DB25 connector labeled PRINTER on
the front side of the back panel.
2.2 CDP Rack Layout
The CDP components are housed on two shelves inside the rack’s lockable enclosure. The
shelves can be accessed via the front door or either of the side doors. The easiest entry point will
depend on the component being accessed.
2.3 CDP Top-Shelf Components
The top shelf (Figure 5) is attached to the back of the CDP monitor and contains the CPU/Hard
Drive assembly, Power Supply, Interface Board, Voice Modem, and communication option
(RS-485 converter or UHF radio). The shelf is accessed by removing four screws from the

• Black wire to GND terminal on the converter.
9. Connect the RJ-11 connector end of the RS-485 cable to the back of the RS-485 RJ-11
jack on the back panel (see Figure 2, Figure 6, and Figure 8).
10. If the RS-485 cable from the DCP is already terminated in an RJ-11 jack, which is likely to
be in a wall-mounted terminal box close to the CDP rack, use the M491861-00 RJ-11 cable
to connect to this jack, then feed the cable through the top of the rack and connect the other
end to the front of the RS-485 jack on the CDP back panel. This completes the installation.
If there is no wall-mounted terminal box, use the M417210-00 RJ-11 terminal box in-
cluded with the RS-485 converter kit. Try to install the M417210-00 RJ-11 terminal box
within 3 feet (1 meter) of the CDP rack on a convenient surface using the two mounting
screws that are included. Use the fork lugs provided to terminate the wires from the DCP.
Although the wires from the DCP may have various colors, the corresponding signals
must be matched with the specified colors inside the terminal box.
• Connect the RS-485(+) wire to the screw terminal associated with the red wire.
• Connect the RS-485(-) wire to the screw terminal associated with the green wire.
• Connect the RS-485 ground wire to the screw terminal associated with the black
wire.
Now you may connect the M491861-00 RJ-11 cable as described at the start of this step.

Connecting the UHF Antenna
When a UHF radio data link is used for communication between the DCP and CDP, the antenna
and antenna cable must be installed. A mast for the antenna should have been installed as part of
the site preparation. The cable from the UHF antenna must be routed to the CDP rack and
connected to the back panel.
1. Install the antenna on the mast provided on the roof of the building, or other appropriate
location. The antenna should be pre-cut for the 450–470 MHz range (standard AWOS
UHF frequency range). Refer to the UHF/VHF Antenna Assembly instructions (in
Chapter 17, Drawings) for more information on how to do this.
2. Connect the UHF connector of the RG-58 antenna cable (Part M491361) to the antenna.
3. Route the antenna cable to the CDP location.
4. Feed the cable through the access hole in the top of the CDP enclosure.
5. If you wish, you may trim the antenna cable before you attach the BNC connector to the
antenna cable. The length of the antenna cable will not affect the operation of the UHF
data link, which will remain within regulatory specifications, although shorter antenna
cable lengths mean less signal loss, and this translates to an increased effective radiated
power by the antenna. The BNC connector is attached as for the VHF antenna cable as
shown in Figure 3.
6. Connect the cable to the BNC connector labeled UHF on the front side of the back panel.

2.5 GPS NTP Time Standard
A Network Time Protocol server using a GPS receiver (see Figure 10) maintains time synchro-
nization at the CDP. The server, housed in a small, oval package, is installed outside the CDP. It
can often be affixed to the top of the rack, depending on satellite reception.
Figure 10. GPS NTP Time Standard Server
To install the GPS NTP Server:
1. Install the server at a location outside the rack with good satellite reception. Depending
on conditions, the server can often simply be affixed to the top of the rack.
If you experience difficulty accessing the GPS satellite signal, move the server to a
location where it has a clear line of sight to the sky without any metal shielding it.
2. Route the server’s cable through the access hole in the top of the rack enclosure
3. Connect the cable to the USB connector labeled GPS on the CDP’s back panel (see
Figure 2).
2.6 NADIN Interface Connection

2.7 Remote Displays Using AWOS Net
An AWOS Net Controller may be used to receive AWOS data directly from the DCP and output
it to a display or local network. When used to provide data over a local network, the controller is
normally installed in the CDP rack as explained in Section 2.4.1.
When used with remote displays, the AWOS Net controller is installed at the site of the remote
display. Three AWOS Net models are available for these remote display applications, with each
model using a different method for communicating with the CDP.
• The 2210 is the standard AWOS Net with an RS-232 link to the AWOS for hard-wired
connections for distances up to 50 feet.
• The 2210-R uses an RS-485 link to the AWOS for hard-wired connections for distances
up to 4000 feet.
• The 2210-U uses a UHF radio link to the AWOS when landline connections are not
feasible.
When RS-232 communication is used, the AWOS Net Controller connects directly to the CDP
within 50 feet of the CDP. In RS-485 and UHF applications, a second small enclosure, the
Communication Interface, houses the hardware for the communication link in the vicinity of the
remote display.
2.7.1 RS-232 Communication Package
The RS-232 communication package should be used when the AWOS Net will be within 50 feet
of the AWOS CDP. Figure 11 illustrates the connections.
The RS-232 communication package consists of the following items.
• M491834-00 serial Y cable, which installs at the CDP and includes a DB9 to RJ-45
adapter
• Second DB9 to RJ-45 adapter, which comes mounted to the data communications serial
connector on the AWOS Net controller
• Power supply consisting of a cable and a power adapter for connecting to AC power
• CAT 5/6 straight-through Ethernet cable (customer supplied), used to connect the AWOS
Net to the CDP
Note that this cable is used only as a serial extension cable, and all that is critical is that
a crossover cable will not work correctly.
Figure 11 shows the CDP connections and the installation of the AWOS Net Controller that are
described below.
