1. INTRODUCTION
The Model 1190 Data Collection Platform (DCP) is used with Automated Weather Observing Systems (AWOS)
for collecting and processing sensor signals. Located at the sensor station, the DCP collects data from the
sensors, performs error detection on the received information, converts the sensors’ data into engineering units,
and transmits a message packet containing sensor data and status information to the Central Data Platform
(CDP) once every five seconds.

2. INSTALLATION
2.1 DCP INSTALLATION
The Model 1190 DCP mounts to the sensor tower
using Unistrut; the optional barometric pressure (Model
7150 or 7190) and radio kits mount inside the DCP
enclosure. Installation drawings in the Drawings chap-
ter of this manual illustrate the installation proce-
dures. Refer to those drawings when installing the
DCP (1190-007), the 7150 or 7190 barometric pres-
sure sensor (M403316-003), and the 20980-A radio
(M403316-003).
Two or three junction boxes—1) AC power,
2) ceilometer and visibility signal, and 3) landline
(present only when a radio data link is not used)—that
were installed during the site preparation procedure
are located at the edge of the tower foundation. After
installing the DCP on the tower, install flexible or
rigid conduit between the junction boxes and the
holes in the underside of the DCP enclosure. Route
the wires from the junction boxes through the conduit
into the DCP.

Simulator to verify the DCP’s +5 V power supply.
2.3 COMMUNICATION CONNECTIONS
The DCP can communicate with the CDP (Central
Data Platform) using one of three available methods:
RS-232, RS-485, or UHF Radio. Only one of these
methods can be in use at any one time, with the active
method determined by the settings of switch SW1.
(Refer to the DIP Switches section of the Operation
chapter of this manual for the required switch
settings.) Connections for RS-232 and RS-485
communication are found at TB4.
2.3.1 TB4—RS-232 Wiring
The distance between the DCP and CDP is generally
too great for RS-232 communication. The RS-232
port provided at pins 5–7 of TB4 is intended as a
maintenance port, allowing DCP operation to be
checked using a laptop computer. The three pins have
the following functions.
1. Pin 5 is data transmit (TX), and should be con-
nected to the laptop’s data receive (RX) line.

1190 Data Collection Platform User's Manual

2. Pin 6 is data receive (RX), and should be con-
nected to the laptop’s data transmit (TX) line.
3. Pin 7 is ground (GND).
Note: Remember that only one communication method
can be in effect at any one time, and is determined by
the SW1 switch settings. If communication between
the DCP and CDP is via RS-485 or UHF radio, other
communication will cease while the RS-232 port is
activated.
2.3.2 TB4—-5 V Power
A –5 V output is available at pin 8 of TB4. This
is used as a test point by the Model 11920 Sensor
Simulator to verify the DCP’s –5 V power
supply.

cate with the CDP, pins 9 and 10 of TB4 are used to
make the connection.
1. Connect the positive lead of the RS-485 line from
the CDP to pin 9 of TB4.
2. Connect the negative lead of the RS-485 line
from the CDP to pin 10 of TB4.
3. Connect the ground lead of the RS-485 line from
the CDP to pin 7 of TB4.
2.3.4 TB4—Other RS-485 Connections
The two remaining RS-485 connections on TB4 (1–2
and 3–4) are used to connect RS-485 sensors such as
the 6490 Present Weather Sensor, 8364-E Visibility
Sensor, the 8339/8340 Ceilometers, and the 6500
Thunderstorm/Lightning Sensor.
Wait until all sensor wires have been inserted when
connecting more than one wire to a terminal block
pin before securing the terminal block screw.

terminal block TB4.
2.4 OTHER SERIAL SENSOR WIRING
When using a 2040/2040H/2040HH Ultrasonic Wind
Sensor, a 6495 Freezing Rain Sensor, or a legacy 8329
Ceilometer, a separate serial sensor interface “daughter
board” is added to the backplane to interface to each
sensor. The daughter boards are connected to one
another via an internal RS-485 bus. Connect the
sensors’ signal cables to their appropriate daughter
boards at TB1 pins 1–3 on the daughter board. The
daughter boards connect to H4 on the DCP.
2.5 POWER WIRING
2.5.1 AC Power Wiring
(See drawing M404802-004 in the Drawings chap-
ter.) AC line power is input to the DCP via the AC
Interface Board (M404802). Connect incoming AC
power to TB1 on the AC Interface Board (not TB1 on
the DCP backplane) as follows:
1. Connect the AC LINE (hot) wire to TB1, pin 1.
2. Connect the AC NEUTRAL wire to TB1, pin 2.
3. Connect the AC GROUND wire to TB1, pin 3.

1190 Data Collection Platform User's Manual

2.5.2 DC, Battery Backup, and Solar
Power Wiring
TB1 on the DCP backplane provides input power
connections for a +15VDC supply (provided by the
AC Interface Board), backup battery power, and solar
power.
+15 V DC Power
The DCP is usually powered by the AC Interface
Board, which provides a +15VDC output. This +15 V
is input to the DCP at pins 5 (+) and 6 (-) of TB1.
1. Connect the positive lead from the AC Interface
Board to pin 5 of TB1.
2. Connect the negative lead from the AC Interface
Board to pin 6 of TB1.
Battery Power
An optional Battery Backup Kit with a battery charg-
ing circuit and a rechargeable 12 V backup battery
allows the DCP to remain powered during short
power outages. The Battery Backup Kit connects to
pins 1 (+) and 2 (-) of TB1.
1. Connect the positive lead to pin 1 of TB1.
2. Connect the negative lead to pin 2 of TB1.
The battery charging circuit on the DCP supplies cur-
rent to the battery at different levels and voltages
depending on the state of the battery. A low-voltage
battery cut-off device in the Battery Backup Kit is
used to power down the DCP during voltage sag
arising from excessive discharge of the battery. As
long as the battery voltage is above the 10.0 V dis-
connect voltage, the charging circuit senses the nor-
mal drop in battery voltage and provides a trickle
charge to charge the battery to its full capacity. The
charging process can be monitored by looking at two
LEDs on the DCP backplane.
When lit, the green BATT. CHARGE LED indicates
that the battery is charged to operating levels and/or
DC power is at normal levels.
When no battery is connected or when the battery
voltage drops below the disconnect voltage, the
BATT. CHARGE LED will be on as long as power
is being supplied to the DCP.
When lit, the red FLOAT CHARGE LED indicates
that the battery is being charged.
When the battery voltage falls below the disconnect
voltage and there is no power being supplied to the
DCP, the FLOAT CHARGE LED will be on and the
BATT. CHARGE LED will be off.
The table below summarizes the DCP Battery LED
status indications.
DC power normal, battery fully charged
DC power low, battery above cutoff voltage
DC power low, battery below cutoff voltage
DC power normal, battery below cutoff voltage
DC power normal, battery above reconnect
voltage but not fully charged
Solar Power
Where conditions permit, the DCP can be powered by
a solar power kit rather than by the AC Interface
Board. (Consult All Weather, Inc. for solar power
requirements for a given site.) The solar power unit
connects to TB1 at pins 3 (+) and 4 (-).
1. Connect the positive lead from the solar power
unit to pin 3 of TB1.
2. Connect the negative lead from the solar power
unit to pin 4 of TB1.

3.2 MAINTENANCE SWITCH
A maintenance switch (SW3) is located on the DCP
backplane, on the lower right side of the board. This
momentary switch should be pressed any time
maintenance is performed on any part of the AWOS
system, prior to beginning maintenance. The switch
closure will be recorded by the CDP, thereby alerting
airport personnel that sensor data may be invalid (due
to calibration or maintenance checks being per-
formed), and keeping an ongoing log of maintenance
activity at the site. The ON state of the switch (shown
both on the DCP’s LCD display and at the CDP) will
be reset to OFF automatically after five minutes. This
switch must be pressed to enable several maintenance
functions from the keypad.
3.3 DIP SWITCHES
(Note: DIP switches SW1 and SW2 are set at the
factory according to each system’s specific
configuration.)
Two DIP switch assemblies (SW1 and SW2) on the
DCP backplane are used to set configuration para-
meters for the DCP. These switches are set at the
factory and should not need to be changed.
The first set of switches, SW1, specifies the commu-
nication method in use between the DCP and CDP
(RS-232, RS-485, or UHF Radio). Table 1 shows the
switch settings for each communication setup.
