Connection Options

The WatchDog weather station communicates with a PC

through either the

Computer

AUX

port which are lo-

cated under the LCD and keypad. The communication

options are separated into 3 main categories.

Direct Communication

There are 3 options for connecting directly to the station.

PC interface cable

The cable that accompanies the

SpecWare software. Connects to the

Computer

port.

A 75

ft Direct Connect Cable (item 3660

75SP)

This

cable has a modular (telephone

type) connector on

one end and a 9

pin RS

232 connector on the other.

Comes with surge protection and connected to the

station through the

AUX

port.

Short

Range Modem Pair

The weather station can

be hardwired up to 4000 feet from a PC with a twisted

pair cable and a short

range modem pair. Powered

with an A/C adapter and connected to the station

through the

AUX

port.

Caution

: Extended lengths of cable can attract lightning.

It is recommended that these cables always be connect-

ed to surge protectors. This provides upgraded protection

against voltage surges caused by nearby lightning strikes.

Wireless Radio Communication

There are 2 options for contacting the station by a wire-

less radio connection. The short

range transceiver can

communicate up to 1000 ft. The mid

range radio has a

range of 2 miles. Both wireless options require line of

sight between the base and remote radios. See the

WatchDog Wireless Modem
