Chapter 1 - Introduction and Specifications
WX-1000 Weather Receiver
The WX-1000 is a highly sensitive, quality receiver, with good front-end protection
designed to function in the high RF environment typical of many repeater sites. A
digital decoder responds to Specific Area Message Encoded (SAME) alerts transmitted
by the NOAA weather station located in your geographic area. Select your county code
and the type of alert. Select warnings and or watches.
During a weather alert, a
relay in the WX-1000 will disconnect the transmitter from the controller and connect
it to the weather receiver.
The relay provides a ground for the transmitter PTT
line. Weather audio will be transmitted for the period of the alert announcement. A
programmable alert timer provides back-up protection.
Weather Alert Log
As alerts are received the WX-1000 stores the date, time and type of alert in nonvolatile memory. Storage space is provided for forty alerts. Use the RS-232 port
and the WX-1000 configuration program to down load the data. A print driver is also
provided.
Front Panel Controls And Displays
Two toggle switches control weather receiver operation. The MONITOR switch activates
the speaker. The VOLUME control includes the power switch and adjusts the speaker
output level. The red ALERT LED flashes when an alert is received. This LED will
continue to flash until the alert period has expired or the spring loaded RESET
switch is pressed. The RESET switch has two functions during an active alert.
A
short activation then release will voice the present alert.
A long activation
(longer than one second) then release will cancel an alert. NOTE: The MONITOR switch
must be down to receive weather alerts.
Alert Start Logic Output (J3-7)
An ALERT START output provides a TTL logic high two second pulse when a weather alert
is received.
This output can be used to set off an external alarm or trigger the
controller to execute a macro or load a “SEVERE WEATHER ALERT” memory save.
Alert Stop Logic Output (J3-6)
Included in the digital packet is the length of the severe weather alert. The WX1000 stores this information and generates a stop logic output when the time period
has expired. An ALERT STOP output provides a TTL logic high for one second. This
output can be used to trigger the controller to reload the “NORMAL” memory save.
Weather Enable Input (J3-9)
When this input is grounded the weather receiver will activate. When connected to a
controller's user function output switch, weather reports on demand are available.
Weather Disable Input (J3-4)
When this input is grounded the WX-1000 will not respond to weather alerts issued by
the NOAA weather station. Once a “Sky Warn Net” is activated, it may be desirable to
stop any additional alerts.
Weather Reset Input (J3-12)
Momentary grounding this input will reset the WX-1000 receiver terminating the alert
and message. Note: From the “WX-1000 Hardware Inputs Outputs” window dot the circle
to select “Cancel any activate alerts.”
3
Alert Message Timer Selection
At the conclusion of an alert message the weather station send a digital termination
packet.
The WX-1000 decodes this packet and turns the transmitter off.
If the
weather station fails to send the termination packet the alert message timer will
take over. Select this time with the WX-1000 configuration program.

Chapter 2 - Interfacing to Repeater
CAT-1000 Interface
Connect the WX-1000 to the CAT-1000 and the repeater as shown in Figure 2-1. PTT and
transmit audio from the CAT-1000 are connected to the repeater's transmitter through
the normally closed contacts of the double pole double throw relay located in the WX1000. Set the power switch to on, the WX-1000 will announce the firmware version.
When a weather alert is received, the relay will switch the weather alert audio to
the TX audio input and provide a PTT signal to key the transmitter.
