Headphone Interface J1
Plug a set of stereo headphones into J1 to monitor the NOAA weather station.
Computer Interface J2
Connect your computer’s serial port to the WX-200 receiver at connector J1. Use Radio Shack shielded
RS-232 cable (cat No. 26-117B) or equivalent. This cable is a DB-9 male to DB-9 female with pins 2-2
and 3-3.
12VDC Interface J3
Connect a 12VDC power supply to the WX-200 receiver through the 2.5mm power jack J2. The
center pin is positive. In stand-by mode the WX-200 requires 100 ma.
Repeater Interface PTT Ground [J4-1]
Connect this pin to the transmitter chassis ground. This will insure that during an alert the PTT line
will be returned to transmitter chassis ground.

Connect this pin to the controller PTT output.
Repeater Interface PTT Output [J4-3]
Connect this pin to the transmitter PTT input.
Repeater Interface Weather Alert Disable Input [J4-4]
Connect this pin to a user function switch on the controller. When this input is grounded, the receiver
will not respond to alerts issued by the weather station. NOTE: When this input is momentary
grounded, the WX-200 will reset, canceling the alert.
Repeater Interface Weather Alert Stop Output [J4-6]
When a weather alert is received, embedded in the digital message is the length of the alert. When
this time period has expired, this output will go active high (TTL) for one second.
Repeater Interface Weather Alert Start Output [J4-7]
When a weather alert is received, this output goes active high (TTL) for one second.
Repeater Interface Ground [J4-8]
Connect this pin to controller ground. This provides a common ground between the controller and
WX-200 receiver.
Repeater Interface Weather Alert Enable Input [J4-9]
Connect this input to a user function switch on the controller. When this input is grounded, the
weather receiver will activate.
Repeater Interface TX Audio Input [J4-10]
Connect this input to the controller transmit audio output.
