Overview
Cable Connection:
The following illustration shows the full segments of the LCD for
description purposes only and will not appear like this during normal
operation and use.
Using this method of operation will provide interference free transfer of the
weather data from the sensors to the base station. The data sending interval
from the sensors to the base station will also be more frequent compared to
using 433MHz transmission and will result in higher power consumption.
Therefore batteries will have a shorter life span for cable connection compared
to using 433MHz. To operate using cable connection, simply use the enclosed
32ft cable and connect the thermo-hygro sensor to the base station. Once the
connection is detected, the base station will automatically continue reading the
data from the sensor.
The user may at any time switch from cable connection to using 433MHz (or
vice versa) by simply disconnecting (or connecting) the cable from the base
station to the sensor. When the base station detects no cable connection to
the sensors, the base station will automatically change to using 433 MHz for
reception of the weather data from the sensors.
The data receiving intervals are as follows:
-
Using cable connection data is updated every 8 seconds.
-
Using wireless 433 MHz data is updated from 16 to 128 second intervals
depending on wind speed and rain activity.
Using the AC adaptor to operate the base station will also supply power to the
sensor if the cable is connected to it. Batteries used for 433MHz transmission
may be left in the sensor when using cable connection for power back up in
case of AC power failure. A loss of power would desynchronize the base
station and the sensor and no weather data will be received. To synchronize
the units so that the weather data can be received, press and hold the PLUS
(+) key for 2 seconds. However in general, batteries that will not be used for
long periods should be removed to avoid leakage.

Using 433MHz wireless transmission of weather data from the sensor to the
base station will provide users greater freedom as to where units can be
positioned without the need to be restricted by cable.
Note:
If no outdoor weather data is displayed or the signal to the sensors is lost
during setting up, mounting, changing of batteries to the sensor or plugging or
unplugging cables, simply press and hold the PLUS (+) key for 2 seconds and
a short beep will sound to synchronize the base station to sensors. Without
being synchronized, weather data will not be received.
